maziggy	019fb1c8af	Track which nozzle each AMS feeds through the Filament Track Switch ... With a switch fitted, an AMS is not wired to a nozzle any more. It is plumbed into one of the switch's two inlets and reaches both nozzles through it, so every unit reports its extruder as "not fixed" (0xE) and ams_extruder_map comes back empty. Bambuddy had nothing to fall back on but the AMS unit number, so AMS-A was badged R and AMS-B was badged L purely because their unit ids are 0 and 1, a third unit got no badge at all, and every one of those labels was wrong. The binding needed no new telemetry. BambuStudio reads it out of bits 24-27 of the same AMS info string we already parse for the type and the extruder id -- 0 is In-B, 1 is In-A -- and it only means anything when a switch is installed, because without one 0xE really does mean an uninitialised unit. That gates the read, which forced the switch block to be parsed before the AMS block: _handle_ams_data runs early in _process_message and _update_state only much later, so the binding was lost on every frame that carried both. The badge letters stay L and R, In-A reading as L, with the inlet named in full in the tooltip -- the letter is the inlet's position and not a claim about which nozzle that AMS feeds, since the switch can route either inlet to either outlet. Both views update live now. The switch fields were missing from the WebSocket payload, and the frontend shallow-merges each push over its cached status, so an absent field kept whatever the last full fetch left behind. The broadcast dedup key had no term for them either, so "Join IN-B" on the printer screen moved nothing: the binding is not in the tray component of that key, and not in the AMS change-hash, which covers tray fields only and must stay that way because it drives Spoolman sync. The rest of this is the calibration half, which is where it actually bites. K-profiles are calibrated per nozzle and the printer numbers its calibration table per nozzle too, so entry 16 exists on both hotends and means a different profile on each. A tray holds exactly one index. Move an AMS to the other inlet and every configured slot in it silently keeps pointing at the old hotend's table -- measured on the maintainer's H2C, a black PLA calibrated 0.018 left and 0.020 right stayed on the left profile after the move, and a manual RFID re-read only re-asserted the same wrong one. Bambu has not solved this either; their AMS dialog carries "TODO: fila_switcher broken the connection of ams->extruder" above the line that decides which nozzle's profiles to offer. Three copies of "which extruder is this slot on" each ended in else 0, which on a switch machine filed every profile under the right-hand nozzle. They now share one resolver that returns None for "unknown", because unknown and extruder 0 are very different answers on a dual-nozzle machine and conflating them is what bound a left-nozzle profile to a slot sitting on the right. The per-slot K value on the printer card had the same confusion from the other direction: its lookup was keyed on cali_idx alone, so one nozzle's K silently overwrote the other's. Moving an AMS now re-selects each configured slot's counterpart profile for the nozzle it has arrived on. Only the calibration binding moves, and only for slots whose spool already has a profile for that nozzle: configuring a slot is a deliberate preparation step, so a slot we know nothing about, or a spool calibrated on one hotend only, is left exactly as the operator set it. Nothing fires on the first sighting of a binding either, since every reconnect learns them afresh and re-applying there would overwrite a choice made by hand. Configure Slot resolves against the slot's own nozzle throughout. Option identity carries the extruder, so a filament calibrated on both hotends gives two distinguishable entries instead of two that collapse into whichever the printer listed first; options name the hotend; matches are scoped to the nozzle the slot feeds, with the other hotend's profiles still reachable under Other K profiles; and the slot's active index is resolved as a pair rather than followed into the wrong table. Inlet to nozzle is one table, In-A to the left hotend and In-B to the right, measured rather than assumed -- fila_switch.out cannot be used for it, reporting [1, 1] unchanged across a 90-second capture, both outlets claiming the same extruder. The print dialog picks up the same inlet labelling in its slot dropdown, replacing a left/right hint that never rendered because it matched snow-encoded values against global tray ids; decoding it correctly would not have saved it, since the firmware never reports which inlet is currently paired with which outlet. The dialog also notes when every filament a print needs sits behind one inlet, which is legal but slow -- a change between two filaments on the same inlet retracts the outgoing spool all the way back to its AMS, where a change across the two only retracts as far as the switch. Assigning an AMS to an inlet remains printer-side. BambuStudio can read that binding and has no command to write it, so there is no wire format to copy.	2026-08-17 15:46:06 +02:00
maziggy	a0778f931b	Show which Filament Track Switch inlet each AMS feeds ... With a switch fitted, an AMS is not wired to a nozzle any more. It is plumbed into one of the switch's two inlets and reaches both nozzles through it, so every unit reports its extruder as "not fixed" (0xE) and ams_extruder_map comes back empty on these machines. The printer card had nothing to fall back on but the AMS unit number, so AMS-A was badged R and AMS-B was badged L purely because their unit ids are 0 and 1, a third unit got no badge at all, and every one of those labels was wrong. The SpoolBuddy assign modal had the same fallback in a worse form, mapping anything that was not extruder 1 to R. The binding turned out to need no new telemetry. BambuStudio reads it out of bits 24-27 of the same AMS info string we already parse for the AMS type and the extruder id -- 0 is In-B, 1 is In-A -- and it is only meaningful when a switch is installed, because without one 0xE really does mean an uninitialised unit and those bits carry nothing. That gates the read, which in turn forced the switch block to be parsed before the AMS block: _handle_ams_data runs early in _process_message and _update_state only much later, so the binding was lost on every frame that carried both. _parse_fila_switch is split out and called first, and left in _update_state as well so that stays a complete absorb step. The badge keeps L and R rather than A and B, because the lettering is familiar and matches the physical layout. It is a different colour from the plain nozzle badge, and its tooltip names the inlet in full, since the letter is the inlet's position and not a claim about which nozzle that AMS feeds -- the switch can route either inlet to either outlet. An AMS still reporting a real extruder id keeps its ordinary badge, which BambuStudio also treats as authoritative over any switch binding, and a switch that has been fitted but not yet set up on the printer shows nothing rather than a guess. The print dialog's slot dropdown gets the same label. It replaces a left/right hint that never once rendered: ftsExtruderForSlot compared snow-encoded in[] values against global tray ids and could not match. Decoding it correctly would not have saved it -- the firmware reports which slot sits in each inlet and which nozzle each outlet feeds, but never which inlet is currently paired with which outlet, so no per-slot nozzle can be derived. That function is gone rather than fixed. The dialog also points out when every filament a print needs sits behind one inlet. Bambu's own guidance is that this is legal but slow: a change between two filaments on the same inlet retracts the outgoing spool all the way back to its AMS before the next can be fed up the shared tube, where a change across the two inlets only retracts as far as the switch. All on one inlet means every change in the job takes the slow path, and moving a single spool fixes it. So it advises, it does not block. Both views update live. Two things were stopping that. fila_switch and ams_switch_inlet were absent from printer_state_to_dict, and the frontend shallow-merges each WebSocket push over its cached status, so a field the push omits keeps whatever the last full fetch left behind. And the broadcast dedup key had no term for either, so "Join IN-B" on the printer screen moved nothing: the binding is not in the tray component of that key, and it is not in the AMS change-hash either, which covers tray fields only and must stay that way because it drives Spoolman sync. Assigning an AMS to an inlet remains printer-side. BambuStudio can read the binding and has no command to write it -- its switch class is parse and getters only, and the recommended-arrangement popup draws and publishes nothing -- so there is no wire format for us to copy. Adding the two fields to PrinterState broke four test modules whose SimpleNamespace stubs predate them. The stubs are fixed rather than the production reads made defensive: the real dataclass always carries both, and a getattr in the dedup key would silently stop tracking the field if it were ever renamed.	2026-08-17 15:45:32 +02:00
maziggy	88feb69bc3	Stop auto K-profile calibration leaving an archive behind ... With flow dynamics calibration on, the printer lays down a pressure-advance line before the print itself and announces it over MQTT through the same print-start event a real print uses. Bambuddy archived it: a row named auto_pa_line_calib_mode marked as having no 3MF, sitting in among the user's actual prints, with a Print Started and a Print Completed notification for each one. The printer's other internal jobs were already skipped, but only by the /usr/ path they carry -- bed levelling reports as /usr/etc/print/auto_cali_for_user.gcode. The pressure-advance line carries no path at all. It arrives as a bare subtask name, so a rule that only ever looked at the filename could not see it. Falling past the guard it reached the no-3MF fallback, where print_name is subtask_name or filename, and named the row after the calibration. Internal jobs are now recognised by name as well as by path, from either field, in one place both callbacks share. The match is exact after normalising away the directory, one print-file suffix and case, rather than a prefix or substring rule: "auto" and "calib" are ordinary words in a user's own filenames, and a rule loose enough to catch some unnamed future calibration would quietly swallow somebody's print. The completion is suppressed too, and that half matters more than the noise. With no archive to close, the completion falls into the no-archive notification path -- which attributes an unmatched completion to any queue item the printer finished in the last five minutes and emails its owner. This calibration runs alongside a real print, so silencing only the start would have told that print's owner their job was done, early, and again for real later. The guard sits inside the no-archive branch, so the plate-clear gate, the queue reconciliation and the SD-card cleanup all still run; only the notification is skipped. Skipping the run early also drops the FTP sweep that preceded the fallback -- six candidate names across five directories with retries, around a hundred connections looking for a file that cannot exist, aimed at a printer that is in the middle of calibrating. auto_cali_for_user no longer sends a Print Started notification either. It is the same event about the same kind of job, and the archive was never the only thing wrong with treating it as a user's print.	2026-08-17 15:45:07 +02:00
maziggy	7354650835	Move Camera View Mode from Settings onto the camera button ... Whether a camera opened in its own browser window or as a floating overlay was one dropdown in Settings > General > Camera, applied to every camera on the install. Deciding per printer meant leaving the Printers page, changing the setting, coming back, opening the camera, and going back again to undo it -- five steps for a choice you make while looking at the printer you want to watch. The camera button on the printer card is now a split control. The icon opens the camera whichever way you opened the last one; the caret beside it offers both modes, and picking one opens the camera that way as well as making it the mode the icon uses from then on. A menu that only changed a preference would have left the user a second click to do the thing they had already asked for. The mode in effect is ticked. The choice lives in the user's own browser, so two people watching the same farm can each have the view they want. camera_view_mode survives as the default a browser that has never chosen starts from, and is written back when the user holds settings:update. The local value wins on read: someone below that permission cannot write theirs back, and a preference that silently reverted on the next render would be worse than none. Two things were consolidated on the way through. The popup-opening code -- saved geometry, and deliberately no noopener so the browser copies sessionStorage and its auth token into the new window -- was duplicated between the printer card and the Cam Wall tile handler; it is now utils/camera, with the geometry parse wrapped so a corrupt cameraWindowState falls back to defaults instead of throwing, which neither copy did. The Cam Wall follows the same remembered mode, since a tile has no room for a split button of its own. The effect that force-closed every open overlay when the setting flipped to window is gone. It made sense for a global switch; with the choice made per click, closing viewers someone deliberately opened does not. No new locale strings: the four the settings control used are reused as the menu's labels and tooltips and the caret's own label, so all 13 locales stay in parity untouched.	2026-08-17 15:44:47 +02:00
maziggy	85dc768b80	Let a busy or offline printer take a dropped file (#2849) ... Dragging a sliced file onto a printer card refused the drop unless the printer was connected and neither RUNNING nor PAUSE. The overlay went red with "Printer busy", handleCardDrop returned early, and the file was discarded with no toast and nothing uploaded. The card's Print button was hidden by the same condition, so both routes into "Print from Printer Card" closed at once and the way through was the File Manager, uploading and queueing by hand. The gate never described a real constraint. Every print Bambuddy sends becomes a queue item; dropping onto an idle printer only looks instant because the scheduler dispatches it on the next pass. Busy is a timing difference, not a different path. The modal has always passed disableBusy={false} to PrinterSelector, and asapToastShouldPromiseLaterStart exists precisely to say "this will start later" when the target cannot take it now. cleanup_library_after_dispatch is a print_queue column consumed at dispatch, not on close, so the transient upload survives however long the item waits. Offline is included for the same reason: the queue dispatches when the printer comes back, so a machine that is powered down can be given work. The overlay now says which one is happening -- "Drop to print" when the job would start immediately, "Drop to queue" when it would wait, covering a print in progress, a paused job, an AMS mid-cycle, a plate not yet cleared, and a printer that is offline. The predicate behind that wording is the one the modal already used for its own later-start notice, lifted out of PrintModal into utils/printer as isPrinterCurrentlyDispatchable so the card cannot promise something the modal contradicts a second later. The drop is also gated on the permissions the flow actually exercises. It uploads to the library and creates a queue item, so library:upload and queue:create -- the pair the Print button beside it has always checked. printers:control, which it checked before and never uses, meant someone holding that alone got the file uploaded and then rejected by the queue, leaving a library row behind with nothing pointing at it. The refusal now names whichever of the two is missing instead of claiming the printer is busy. printers.cannotPrint is dropped in favour of printers.dropToQueue across all 13 locales; its text was both unused and, after this, wrong. The Print button stays inside the expanded-card block, so S-size cards still show the drop zone and no button, exactly as before.	2026-08-17 15:44:18 +02:00
maziggy	64a1defa7a	Stop the AMS temperature alert firing for heat the user asked for (#1802) ... The alert compares against ams_temp_fair, the same threshold that colours the printer card, which defaults to 35C. Drying deliberately runs at 45C for PLA, 65C for PETG and up to 85C on an AMS-HT, and the alert repeats once an hour for as long as the condition holds, so a twelve-hour dry sent twelve notifications about a temperature the user chose. It then kept sending them while the unit cooled back down, which is the half the reporter confirmed on an AMS 2 Pro and an H2C. Dispatch now consults the drying state the firmware already reports. dry_time alone is not enough: it reads 0 through the cooling phase that closes a cycle, so dry_status -- info bits 4-7, already parsed for the drying-complete edge -- carries the rest. That constant moves out of bambu_mqtt into a leaf util rather than being duplicated; drying_preflight would have been the natural home, but it imports printer_manager, which imports bambu_mqtt, and bambu_mqtt is one of the callers. The cool-down afterwards is held by a latch released as soon as the unit reads back at or below the threshold, rather than after a fixed delay, so a 65C cycle in a cold basement and a 45C one in a warm room each get the time they actually need. A two-hour cap bounds the one case the latch cannot resolve on its own -- a unit that never returns below the threshold -- and since such a unit would have been alarming with no drying involved, releasing there restores the ordinary behaviour instead of inventing a new alert. Two exclusions are deliberate. Humidity is untouched, because during drying that reading falling is the whole point. And dry_status 6, HeatOutOfControl, is kept out of the active set: an AMS that has lost thermal control is exactly when the alert should still arrive, so it must never read as expected heat. A cycle plus its cool-down outlasts a restart, so the latch is a settings row rather than a dict beside _ams_alarm_cooldown -- the internal timestamp-row pattern support.py already uses. It is read once per pass and written back only when a unit changed it. Stamps ahead of now are clamped on read, since a box whose clock jumps backwards writes them and suppression is measured as now minus the stamp; without the clamp the cap would measure from a moment that has not happened yet and hold the alert quiet for the skew on top of it. No new setting. The reporter was offered the opt-out checkbox they asked for and said they would not want it if the alert simply never fired during drying.	2026-08-17 15:43:42 +02:00

maziggy	c5e0055864	Track which nozzle each AMS feeds through the Filament Track Switch ... With a switch fitted, an AMS is not wired to a nozzle any more. It is plumbed into one of the switch's two inlets and reaches both nozzles through it, so every unit reports its extruder as "not fixed" (0xE) and ams_extruder_map comes back empty. Bambuddy had nothing to fall back on but the AMS unit number, so AMS-A was badged R and AMS-B was badged L purely because their unit ids are 0 and 1, a third unit got no badge at all, and every one of those labels was wrong. The binding needed no new telemetry. BambuStudio reads it out of bits 24-27 of the same AMS info string we already parse for the type and the extruder id -- 0 is In-B, 1 is In-A -- and it only means anything when a switch is installed, because without one 0xE really does mean an uninitialised unit. That gates the read, which forced the switch block to be parsed before the AMS block: _handle_ams_data runs early in _process_message and _update_state only much later, so the binding was lost on every frame that carried both. The badge letters stay L and R, In-A reading as L, with the inlet named in full in the tooltip -- the letter is the inlet's position and not a claim about which nozzle that AMS feeds, since the switch can route either inlet to either outlet. Both views update live now. The switch fields were missing from the WebSocket payload, and the frontend shallow-merges each push over its cached status, so an absent field kept whatever the last full fetch left behind. The broadcast dedup key had no term for them either, so "Join IN-B" on the printer screen moved nothing: the binding is not in the tray component of that key, and not in the AMS change-hash, which covers tray fields only and must stay that way because it drives Spoolman sync. The rest of this is the calibration half, which is where it actually bites. K-profiles are calibrated per nozzle and the printer numbers its calibration table per nozzle too, so entry 16 exists on both hotends and means a different profile on each. A tray holds exactly one index. Move an AMS to the other inlet and every configured slot in it silently keeps pointing at the old hotend's table -- measured on the maintainer's H2C, a black PLA calibrated 0.018 left and 0.020 right stayed on the left profile after the move, and a manual RFID re-read only re-asserted the same wrong one. Bambu has not solved this either; their AMS dialog carries "TODO: fila_switcher broken the connection of ams->extruder" above the line that decides which nozzle's profiles to offer. Three copies of "which extruder is this slot on" each ended in else 0, which on a switch machine filed every profile under the right-hand nozzle. They now share one resolver that returns None for "unknown", because unknown and extruder 0 are very different answers on a dual-nozzle machine and conflating them is what bound a left-nozzle profile to a slot sitting on the right.

maziggy	9c93884397	Stop auto K-profile calibration leaving an archive behind ... With flow dynamics calibration on, the printer lays down a pressure-advance line before the print itself and announces it over MQTT through the same print-start event a real print uses. Bambuddy archived it: a row named auto_pa_line_calib_mode marked as having no 3MF, sitting in among the user's actual prints, with a Print Started and a Print Completed notification for each one. The printer's other internal jobs were already skipped, but only by the /usr/ path they carry -- bed levelling reports as /usr/etc/print/auto_cali_for_user.gcode. The pressure-advance line carries no path at all. It arrives as a bare subtask name, so a rule that only ever looked at the filename could not see it. Falling past the guard it reached the no-3MF fallback, where print_name is subtask_name or filename, and named the row after the calibration. Internal jobs are now recognised by name as well as by path, from either field, in one place both callbacks share. The match is exact after normalising away the directory, one print-file suffix and case, rather than a prefix or substring rule: "auto" and "calib" are ordinary words in a user's own filenames, and a rule loose enough to catch some unnamed future calibration would quietly swallow somebody's print. The completion is suppressed too, and that half matters more than the noise. With no archive to close, the completion falls into the no-archive notification path -- which attributes an unmatched completion to any queue item the printer finished in the last five minutes and emails its owner. This calibration runs alongside a real print, so silencing only the start would have told that print's owner their job was done, early, and again for real later. The guard sits inside the no-archive branch, so the plate-clear gate, the queue reconciliation and the SD-card cleanup all still run; only the notification is skipped. Skipping the run early also drops the FTP sweep that preceded the fallback -- six candidate names across five directories with retries, around a hundred connections looking for a file that cannot exist, aimed at a printer that is in the middle of calibrating. auto_cali_for_user no longer sends a Print Started notification either. It is the same event about the same kind of job, and the archive was never the only thing wrong with treating it as a user's print.	2026-08-16 14:01:33 +02:00
maziggy	61a6ed1f20	Move Camera View Mode from Settings onto the camera button ... Whether a camera opened in its own browser window or as a floating overlay was one dropdown in Settings > General > Camera, applied to every camera on the install. Deciding per printer meant leaving the Printers page, changing the setting, coming back, opening the camera, and going back again to undo it -- five steps for a choice you make while looking at the printer you want to watch. The camera button on the printer card is now a split control. The icon opens the camera whichever way you opened the last one; the caret beside it offers both modes, and picking one opens the camera that way as well as making it the mode the icon uses from then on. A menu that only changed a preference would have left the user a second click to do the thing they had already asked for. The mode in effect is ticked. The choice lives in the user's own browser, so two people watching the same farm can each have the view they want. camera_view_mode survives as the default a browser that has never chosen starts from, and is written back when the user holds settings:update. The local value wins on read: someone below that permission cannot write theirs back, and a preference that silently reverted on the next render would be worse than none. Two things were consolidated on the way through. The popup-opening code -- saved geometry, and deliberately no noopener so the browser copies sessionStorage and its auth token into the new window -- was duplicated between the printer card and the Cam Wall tile handler; it is now utils/camera, with the geometry parse wrapped so a corrupt cameraWindowState falls back to defaults instead of throwing, which neither copy did. The Cam Wall follows the same remembered mode, since a tile has no room for a split button of its own. The effect that force-closed every open overlay when the setting flipped to window is gone. It made sense for a global switch; with the choice made per click, closing viewers someone deliberately opened does not. No new locale strings: the four the settings control used are reused as the menu's labels and tooltips and the caret's own label, so all 13 locales stay in parity untouched.	2026-08-16 13:43:15 +02:00
maziggy	47a37618a0	Let a busy or offline printer take a dropped file (#2849) ... Dragging a sliced file onto a printer card refused the drop unless the printer was connected and neither RUNNING nor PAUSE. The overlay went red with "Printer busy", handleCardDrop returned early, and the file was discarded with no toast and nothing uploaded. The card's Print button was hidden by the same condition, so both routes into "Print from Printer Card" closed at once and the way through was the File Manager, uploading and queueing by hand. The gate never described a real constraint. Every print Bambuddy sends becomes a queue item; dropping onto an idle printer only looks instant because the scheduler dispatches it on the next pass. Busy is a timing difference, not a different path. The modal has always passed disableBusy={false} to PrinterSelector, and asapToastShouldPromiseLaterStart exists precisely to say "this will start later" when the target cannot take it now. cleanup_library_after_dispatch is a print_queue column consumed at dispatch, not on close, so the transient upload survives however long the item waits. Offline is included for the same reason: the queue dispatches when the printer comes back, so a machine that is powered down can be given work. The overlay now says which one is happening -- "Drop to print" when the job would start immediately, "Drop to queue" when it would wait, covering a print in progress, a paused job, an AMS mid-cycle, a plate not yet cleared, and a printer that is offline. The predicate behind that wording is the one the modal already used for its own later-start notice, lifted out of PrintModal into utils/printer as isPrinterCurrentlyDispatchable so the card cannot promise something the modal contradicts a second later. The drop is also gated on the permissions the flow actually exercises. It uploads to the library and creates a queue item, so library:upload and queue:create -- the pair the Print button beside it has always checked. printers:control, which it checked before and never uses, meant someone holding that alone got the file uploaded and then rejected by the queue, leaving a library row behind with nothing pointing at it. The refusal now names whichever of the two is missing instead of claiming the printer is busy. printers.cannotPrint is dropped in favour of printers.dropToQueue across all 13 locales; its text was both unused and, after this, wrong. The Print button stays inside the expanded-card block, so S-size cards still show the drop zone and no button, exactly as before.	2026-08-16 12:59:59 +02:00
maziggy	7a9b4921bd	Stop the AMS temperature alert firing for heat the user asked for (#1802) ... The alert compares against ams_temp_fair, the same threshold that colours the printer card, which defaults to 35C. Drying deliberately runs at 45C for PLA, 65C for PETG and up to 85C on an AMS-HT, and the alert repeats once an hour for as long as the condition holds, so a twelve-hour dry sent twelve notifications about a temperature the user chose. It then kept sending them while the unit cooled back down, which is the half the reporter confirmed on an AMS 2 Pro and an H2C. Dispatch now consults the drying state the firmware already reports. dry_time alone is not enough: it reads 0 through the cooling phase that closes a cycle, so dry_status -- info bits 4-7, already parsed for the drying-complete edge -- carries the rest. That constant moves out of bambu_mqtt into a leaf util rather than being duplicated; drying_preflight would have been the natural home, but it imports printer_manager, which imports bambu_mqtt, and bambu_mqtt is one of the callers. The cool-down afterwards is held by a latch released as soon as the unit reads back at or below the threshold, rather than after a fixed delay, so a 65C cycle in a cold basement and a 45C one in a warm room each get the time they actually need. A two-hour cap bounds the one case the latch cannot resolve on its own -- a unit that never returns below the threshold -- and since such a unit would have been alarming with no drying involved, releasing there restores the ordinary behaviour instead of inventing a new alert. Two exclusions are deliberate. Humidity is untouched, because during drying that reading falling is the whole point. And dry_status 6, HeatOutOfControl, is kept out of the active set: an AMS that has lost thermal control is exactly when the alert should still arrive, so it must never read as expected heat. A cycle plus its cool-down outlasts a restart, so the latch is a settings row rather than a dict beside _ams_alarm_cooldown -- the internal timestamp-row pattern support.py already uses. It is read once per pass and written back only when a unit changed it. Stamps ahead of now are clamped on read, since a box whose clock jumps backwards writes them and suppression is measured as now minus the stamp; without the clamp the cap would measure from a moment that has not happened yet and hold the alert quiet for the skew on top of it. No new setting. The reporter was offered the opt-out checkbox they asked for and said they would not want it if the alert simply never fired during drying.	2026-08-16 11:45:46 +02:00

The scan pinned Trivy v0.69.1, which aquasecurity have since deleted -- retained releases now run v0.74.0 down to v0.69.2 and then jump back to v0.26.0. The tag survives, so setup-trivy resolves it, reports "found version: 0.69.1" and then exits 1 with no asset to fetch. This repository did not notice because the binary was coming back from the Actions cache on every run, which skips the download. Forks have no such cache, which is where it was reported from -- and the same failure was due here the first time that entry went cold. Both scans move to trivy-action v0.36.0 and Trivy v0.74.0; every input they pass is still declared in the new action. The comment records that this pin has to be bumped rather than left, and that a green run is not evidence it still resolves. The config scan is clean on v0.74.0, so the bump adds no new misconfiguration alerts.	2026-08-16 10:17:02 +02:00

maziggy	713a85d114	Let a bug-report capture outlive the panel that started it (#2847) ... Step 2 asks the user to reproduce the problem, and the panel sits over the part of the app they have to reach to do it. Closing it was the obvious move and it was wrong in two different ways, picked by timing alone. Reopen inside five minutes and the reset-on-open effect put you on an empty step 1 while the server stayed at DEBUG, with nothing left in the flow that could stop it -- only Stop & Submit ever did. Leave it closed and the cap fired behind you: the panel is hidden but mounted, so the timer kept running, stopped logging and filed the report with no window open and no confirmation. A capture is now written down -- description, email, was_debug and a start timestamp -- and the reset skips a run in progress, so the panel reopens on the step it left. The disc turns amber while a capture is going and Layout marks the compact header's button and offers Resume report on the debug-logging banner, since a run started there ends at that panel's button and not at the System page's raw toggle. If the cap fires while the panel is closed, it opens first, so the submission happens in front of the user. Elapsed is measured against the start time rather than counted in ticks, which a background tab throttles hard enough that five minutes was not five minutes. That timestamp also lets a run survive a reload, which matters because reloading is an ordinary step in reproducing a bug: on mount a stored run is reconciled against /support/debug-logging and resumed. One that outlived the cap unattended is not resumed and not filed -- an hour-old description is not a report anyone still expects -- but its log level is put back, which is what stayed wrong indefinitely before. The screenshot is deliberately not persisted: a 1920px JPEG runs to hundreds of kilobytes against an origin-wide budget, and it survives a close either way.	2026-08-16 09:55:12 +02:00
maziggy	a72f49be02	Stop the File Manager card menu from clipping its own top entry (#2846) ... A grid card drew its action menu inside itself and clipped its own overflow, so a card shorter than its menu lost whichever entry sat at the top. An STL card is the shortest in the library -- a square thumbnail plus a name and a size, around 270px against a seven-entry menu needing closer to 310px -- and the entry it lost was Slice, since Print is only offered for an already-sliced file. A 3MF carries a target model and a print count, two more rows, so its card was tall enough and the button appeared, which made this read as a rule about file types. It was not: the shortest card lost its first item, whatever that item was. The menu is now the shared ContextMenu, anchored to the kebab in viewport coordinates the way the archive card has always opened its own. Being fixed, it escapes both clipping ancestors -- the card and the grid's scroll container, which would have cropped the top row of cards even without the card's own overflow. The card drops overflow-hidden anyway and the thumbnail rounds its own corners instead, so nothing a child positions outside the card can be cut off again. While rewriting the block, 3D Preview and its permission tooltip stop being hardcoded English; fileManager.preview3d and fileManager.noPermissionPreview are added to all 13 locales. List view was never affected: it has no menu, only inline buttons.	2026-08-16 09:40:03 +02:00

MartinNYHC	caea50f2ca	Merge pull request #2840 from maziggy/1.2.5.3 ... **Bambuddy 1.2.5.3** **What this is** A feature-and-fix release on top of 1.2.5.2, with four things carrying most of it: the slice dialog gains OrcaSlicer's full process-parameter set, the G-code and model previews are rebuilt on the slicer's own renderer, the H2C's six-hotend nozzle rack can finally be aimed rather than guessed at, and selected categories can be restored from a Git backup commit. Around it are 39 fixes, a heavy run of them on AMS drying, slicing and the queue. Five of the features come from outside contributors. No breaking changes. Several table and column additions are applied automatically on both SQLite and PostgreSQL.

There is now a finance layer behind the print flow: cost centres with budgets, per-user wallets, and a transaction for every print. A cost centre can be picked in the print dialog, travels with the queue item and the archive, and is reserved against before the job is dispatched rather than after it finishes, so a print that would take a budget past its limit does not start. Charges settle on real filament usage at completion, and a print that aborts part-way is charged for the part that ran instead of being written off or billed in full. Every user gets a personal cost centre and wallet on first sign-in, including the first sign-in through LDAP, so a directory-backed install does not need them created by hand. A monthly reset day and timezone decide when budgets roll over. The whole feature is behind a billing toggle and is off by default, and an optional printer kill switch stops dispatch entirely once a budget is exhausted. Cost-centre management has its own permissions rather than riding on the settings ones, so a farm can let someone spend against a budget without letting them change it. Ships with a Finance page, migrations for both SQLite and PostgreSQL, and translations in all locales. - One queue item, several printer models — whichever frees up first (#671, reporter @brainomite; also delivers most of #2570, reporter @NeighborGeek) — With an H2S and an H2C, a job you don't care which machine runs still had to be queued twice: the two printers need different slices, a queue item held exactly one file, and "any H2S" and "any H2C" were separate jobs competing for the same plastic.

Order is yours to set, because "both are free right now" has to resolve the same way every time rather than following whichever match the matcher happened to see first. Candidates are otherwise tried least-attempted first, so a printer that accepts the file and never starts hands the job to the other machine on the next lap instead of spending the item's whole retry budget on the one that is wedged. The set is validated as a set: one file per printer model (two slices for the same machine are not alternatives, and picking between them arbitrarily would look like a bug the first time it chose your draft profile), every file gated against the model it is offered as, and at least one model that actually has a printer — grouping the H2C slice before the H2C arrives is fine, queueing a job nothing can ever run is not. A cross-model item deliberately holds no file of its own, so deleting one alternative leaves the job and its sibling intact; deleting or trashing every candidate holds it with an explanation instead of failing deep in the upload. Filament overrides offer everything loaded across **all** the candidate models rather than just the first — a spool loaded on only one of them is still a legitimate choice, it simply narrows which candidates can match — while AMS slot mapping is absent exactly as it is on an ordinary "Any [model]" job, because no printer has been picked yet and the scheduler derives the mapping against whichever one it takes. In the queue the job reads **Any H2D / X1C**, naming every model it is waiting on rather than filing itself under one it may never run on, and its waiting reason is given per model (`H2D: Busy: H2D-1; X1C: No matching material/color`), collapsing to a plain busy message — and no notification — when every model is merely printing. The alternatives are fixed once queued: the schedule, quantity and print options stay editable, but assigning a specific printer or narrowing to one model is refused by both the dialog and the API, since an item holding alternatives *and* a printer would dispatch down the fixed-printer path with no file to send. Cancel and re-queue to change the set. Files can also be grouped permanently with **Group as versions**, after which printing any one of them offers the others without re-selecting — this is the grouping and the print-time file matching asked for in #2570, minus its nested File Manager listing. An existing library arrives with its groups already built, from slice provenance Bambuddy has been recording since the Slice button shipped and had never read back. Translated in all locales; wiki updated. Covered by backend and frontend tests. - Batch orders: a quantity per plate, and an order that knows what it still owes (#342, reporter @cimdDev) — Printing a multi-plate file in different quantities per plate meant queueing each plate separately and tracking the counts yourself, because one shared **Quantity** field cannot say "plate 1 once, plate 2 twice, plate 3 three times". Each selected plate of a multi-plate file now carries its own quantity, and the submission becomes a **batch order** on a new **Batches** tab of the Print Queue page. What that buys is the distinction the old batch could not express: the order records how many runs of each plate were *wanted*, separately from what was queued. A run that fails, is cancelled or is skipped does not satisfy a target, so the order goes on saying it owes a print instead of quietly under-delivering — and a **Queue remaining** action re-queues exactly what is missing, for the whole order or one plate. Those new items are copied from the most recent run of that plate, so they inherit the printer or model target, AMS mapping, filament overrides and print options already chosen, and they are appended to the end of the relevant printer's queue rather than jumping ahead of work already lined up. Orders show progress against target, per-plate breakdown, and cost. Cost is measured rather than estimated: each finished run's material and energy are attributed through the queue item that produced them, so an unrelated reprint of the same file never lands in an order's total, and a multi-plate order gets each plate's own cost rather than the whole file's. Before any run has completed there is no honest figure, so cost reads as unknown instead of a fabricated `0.00`. An order becomes **completed** the moment its last run lands rather than whenever someone next opens the page, and raising a target on a finished order reopens it. Targets stay editable while the order runs, since production requirements change mid-job. The default flow is unchanged — creating an order still queues all of it immediately, and a single-plate file still has one Quantity field. Batches created before this release keep working and are labelled **Grouping only**: they only ever knew what was queued, not what was wanted, so they report progress but have nothing to dispatch. They also get closed out on the first start after upgrading — `completed` was not a reachable status before now, so every batch created since grouping shipped is still marked active however long ago its last print finished, and without that pass the new tab would open on months of accumulated history. Only batches with nothing queued or printing are touched: those whose runs all completed become completed, and groupings whose items were all cancelled become cancelled, which is what they are — calling them completed would claim output that never happened. Batches with neither queue items nor targets are no longer listed at all; those are empty shells left behind when a grouping's items were deleted with their source archive. Translated in all locales; wiki upd ated. Covered by backend and frontend tests. - Nest projects under a master project and roll their figures up (#1264) — Projects were flat. The `parent_id` column and the sub-project list already existed but nothing outside the API could set a parent, and a master project's statistics only ever covered its own prints. The project dialog now has a parent picker, and a project with sub-projects gets a second card covering the whole tree: jobs, parts, time, filament, cost, and progress against every target in the tree added together. That card is deliberately separate from the project's own stats, which keep their existing meaning — widening them would have restated the figures of anyone who had already nested projects over the API. Each listed sub-project carries its own branch's roll-up, so the rows add up to the card above them. On the Projects page a sub-project is drawn inside its parent's group rather than as another card in the grid, because two cards columns apart cannot show that they belong together whatever the caption says. Translated in all locales; wiki updated. - Keep the chamber warm between prints and skip a soak that is not needed (#2727, contributor @ticfinack) — Back-to-back prints in chamber-heated materials — ASA, ABS, PA, PC — each paid a full heat soak from cold, even when the print that just finished had left the chamber at temperature. Two changes remove that cost. While a printer sits in FINISH waiting for plate-clear and the next queued item needs chamber heat, the bed is held hot so the chamber does not cool during the bed-clearing window. The bed is the chamber's heating element here rather than a print surface, so the hold runs at the new **Keep-warm bed temperature** (90 °C by default, which also satisfies the aftermarket chamber heaters that trigger off a bed threshold) and rises to the item's own bed temperature when that is higher. It is gated on the keep-warm setting, on plate-clear being required, and on the next item actually needing the heat, and it is capped by a maximum duration so a queue that stalls does not leave a bed hot indefinitely. A follow-up closed the two dispatch exits that could drop the hold without releasing it — a claim failure returns before the rollback opens, and a vanished row left the printer id unset, which the rollback guards on — either of which left a bed hot with nothing tracking it, reachable whenever a cancel or delete landed between selection and the claim. - Restore selected categories from a Git backup commit — Bambuddy has pushed backups to GitHub, GitLab, Gitea and Forgejo for a while; now it can read one back. Pick a commit, preview what it holds, choose which categories to restore (#2656, contributor @jmoore-skild). - Edit the full print-parameter set from the slice dialog — the dialog now carries OrcaSlicer's own process tree, with its pages, groups, tooltips and ranges, and evaluates the slicer's own enable/disable rules. Slicing no longer means taking a preset exactly as it comes. - A new G-code and model preview — the vendored PrettyGCode iframe is gone, replaced by libvgcode, the renderer OrcaSlicer draws its own preview with. Real occlusion instead of screen-space lines, and it is themed and translated like the rest of the app. The model preview was rebuilt alongside it, with proper framing and lighting. - Choose which rack nozzle each filament prints from on an H2C (#1784) — the Vortek rack holds six hotends and the choice is not recorded in the 3MF, so plates went out with no assignment and the printer picked for itself. Every rack-bound filament now has a position picker showing all six and the nozzle each holds. - Home Assistant sensors on the printer card, with an optional print interlock (#1148, reporter @bsaunder; #448, reporter @baudneo) — surface HA entities on the card, and optionally block a print from starting when one of them says not to. - The Print Log shows how much filament a run used, and lets you choose its columns (#2636, reporter @ajbastien). - Auto-orient and auto-arrange when slicing server-side (#2548, reporter @ceokingcobra). - Open a File Manager model in your desktop slicer, and pick which one from the 3D preview (#2725, contributor @pascalheidmann). - Server-side slicing on an ARM64 host (#1900, contributor Felix Reissmann) — an override pins the sidecar to amd64 and runs it under emulation, with the binfmt requirement and the three-to-six-times slowdown stated up front. A separate x86_64 machine is still the recommendation. - Temperatures on the streaming overlay, and a builder for its URL (#1422, reporter @SMAW). - Open a multi-plate sliced file on the plate you asked for — the viewer gains a plate switcher and keeps the choice in its URL, and filament colours follow it instead of always coming from the first plate. - Show the plug that actually powers the printer in the card's Power row (#2830) — which plug filled that row was previously decided by nothing at all, so it could land on an enclosure fan and offer to switch the printer off by cutting it. - The Printers page remembers its status and location filters (#2833) — the only two preferences on that page that were not persisted. - The external spool can be hidden from the printer card (#1782, reporter @Arn0uDz). - Uploaded archives can be named after the filename you sent (#2610, contributor @Person2099). - The chamber temperature limit is raised from 60 to 65 °C (reported on Discord). - The Spool Inventory can be sorted by colour rather than by colour name (#2729, reporter @macwhiz). - API keys can read and run slicer pipelines (#1425) — every pipeline endpoint answered 403 to a key whatever scopes it carried. Running a pipeline requires the queue and library-manage flags together, and a 403 now names every flag the key is short of. - API clients can resolve user ids to names (#1894) — archives, the queue and statistics report ownership as a numeric id, and nothing let a key discover whose id was whose without an admin listing. - Forgejo tokens scoped to a single repository are accepted (#2775) — a repository-scoped v15 token was rejected for failing a user lookup it does not need to pass. - The MQTT debug log records the commands sent to a printer, not only what it reports back. - Queue items created from the Library's bulk Add to queue and through the webhook API now record who created them, so own-work permissions can see them. **Fixes** **H2C and multi-nozzle:** - An H2C levelled on one hotend and printed with another, several millimetres above the plate (#2800). A print command names the rack nozzle by physical position rather than by extruder index, and Bambuddy only ever had that position for jobs arriving through the Virtual Printer — everything else omitted the field and let the firmware choose. Two hardware-derived values were then corrected by the reporter's own A/B on real hardware, and the fixed/rack carriage assignment turned out to be inverted. - An H2C refused a multi-colour print outright with HMS 0500-4047, a hotend mismatch: on a rack machine the slicer writes a filament group per nozzle rather than per carriage, so a three-group plate lost a filament against a two-entry map. - The H2C nozzle rack card sizes itself to its contents instead of claiming several hundred pixels and leaving them empty, numbers its slots 1 to 6, and scales its chips with the card size. **AMS, drying and filament:** - AMS drying was torn down and restarted once per scheduler tick while a plate sat unacknowledged — about 2000 state changes over ten days, with no cycle ever running long enough to remove moisture, and hand-started cycles on other units of the same printer torn down with them (#2801). - Auto-drying re-armed into a threshold it could never reach (#2770) — an AMS reads a higher humidity warm than cold, so the reading at the moment a cycle ended always armed the next one. Five twelve-hour cycles inside four hours. - A drying cycle the printer abandons now says so, and says what the printer reported (#2770, reporter @tchavei). - A drying cycle no longer reports itself finished a minute after it starts (#2759). - The drying badge invented a temperature on a uniformly loaded AMS, showing the spools' RFID recommendation rather than the temperature that was picked (#2759 follow-up). - The drying popover no longer starts a cycle under a material you did not pick (#2774). - The nearest filament colour is picked instead of the first eligible one in tray order, and the ranking is perceptual — RGB distance overweights blue badly enough to invert the answer (#2804, #2823, contributor @grolmus). Filament type matching also agrees between the interface and the scheduler now. - Spoolman no longer charges a Bambu Studio print to the wrong spool (#2768). - "Any X2D" works on a printer that feeds from external spools instead of an AMS (#2771, reporter @Nick-C130). - AMS Filament Backup no longer charges a whole print to the substitute spool — everything needed to split the filament across the trays it actually came from lived only in memory, so a print that outlived a restart lost it. - The print dialog pools AMS Filament Backup spools in its filament check, instead of refusing a job against one slot while an identical full spool sat in the next one. - A refused AMS filament setting now says so in the log (#2756, reporter @Jostxxl). - Configuring an AMS slot shows up on the printer card straight away, without a page reload. **Queue and dispatch:** - A completion for one print closed another print's queue item, marking it completed while the printer was still working and stranding the rest of its batch (#2829). The check that fixes it also had to learn that the printer rewrites the name it echoes back, which had left queues stopped until someone cancelled by hand. - Deleting a library file destroyed the jobs queued against it — silently on PostgreSQL, and as "Library file not found" days later on SQLite (#2819). - A library-backed job was dispatched onto a spool that could not finish it: 20.5 g needed, 9 g loaded, no deficit reported (#2779). Slicer pipeline jobs and everything from the Library's bulk add were affected. - A job queued to a printer class never powered a printer on, while the same file pinned to a specific printer did (#2786). - A print that never starts now says AMS drying was running, instead of blaming the SD card (#2758). **Slicing and previews:** - A slice failed on a model whose name contains a slash — a MakerWorld title arrives with its punctuation and was used verbatim as a folder name (#2832). - A slice of a file on a network share was written to managed storage instead, showing up in the right folder in the interface and never reaching the share (#2810). - A 3MF no longer switches off supports its process preset turned on (#2820) — the carry that lets a project's support configuration survive was running in both directions. - An oversized model reads as an oversized model, not a slicer crash (#2802). The advice to update the sidecar was wrong too: it named a bare compose pull, which skips the profile-gated sidecar silently. - A preview slice no longer gives up on custom G-code the sidecar cannot parse — the silent fallback to guessing from painted faces was dropping a whole filament slot. - Bundled presets resolved their start G-code to a generic block: all 56 instantiable BBL machine presets, producing a print that heats the bed, moves the toolhead and extrudes nothing. - The process-settings panel shows the preset's own values instead of the compiled-in defaults, and names which of four causes applied when it cannot read them. - Server-side slicing is no longer offered for STEP files, which neither slicer can load from its command line. Open in Slicer still hands them to the desktop application. **Printers, archives and connection:** - Archives arrived empty from printers whose file service could not answer (#2780). Two faults: H2-series and P2S firmware can keep the sliced file on internal storage, which port 990 cannot reach — the print command says which, and we discarded it and swept anyway, around 110 doomed connections per print. And a printer whose FTPS handshake wedges now gets a five-minute cool-off instead of being retried hundreds of times a minute; one reporter's log carried 1813 identical failures, another's 3511. - Photos and filament accounting on archives that arrive without a 3MF, which on an H2S is any job started from the printer's own library (#1820). Photos were written in one place and looked for in another, and the fallback that stands in for a missing 3MF could charge nothing without a word. - The printer card thumbnail is back after navigating away and returning (#2826) — a cache hit raced the mount effect, which is why it reproduced every time for the reporter and never here. - Live updates stopped arriving while the Bambuddy tab was in the background (#2754, reporter @mic4rd). - A print stage Bambuddy cannot name is now logged at INFO, once per stage number per session, with the context needed to name it afterwards. **Interface:** - Interactive controls show a pointer cursor again (#2791) — Tailwind v4 dropped the base rule and only 15 of 934 buttons had it written by hand. - The Spool Inventory header no longer scrolls the whole page sideways on a phone (#2813). - The Virtual Printer card header wraps instead of painting outside its border (#2808). - A refused frame no longer leaves the browser's own error page inside Bambuddy's layout, and says which header blocked it (#2787). - Form controls follow the page's colour scheme — steppers, calendar buttons, dropdowns and scrollbars were drawn light on every theme. - The L and XL printer cards scale their text and icons, not just their width (#1848, reporter @misterff1). - The bug-report button no longer covers the controls in the bottom-right corner (#2750, reporter @goodjaltman). - Error and warning toasts stay up twice as long. - The Print Log is reachable again once you have no archives, and its cost and energy figures reach the browser at all. - The Docker update command is copyable, and knows where your compose file lives (#2664, reporter @pchulpjoost). - The Slicer Bundles notice is gone from Settings — bundle import was withdrawn in 0.2.5 and the panel had been sitting there since, unactionable. **Login, deployment and integrations:** - LDAP login works again on directories that define no POSIX group class (#2769, reporter @peterskotte). - A hand-written systemd service left the Virtual Printer unable to start, with nothing obvious to blame (#2549, reporter @Ru3ck3). - Bambu Cloud's anti-robot challenge is explained instead of repeated back as a bare error with nothing to click (#2790). - Home Assistant notifications carry nested data through unchanged (#1441). **Security (dependencies)** - Cleared every remaining npm audit and pip-audit finding. react-router and react-router-dom move to 7.18.2, which retires the documented CSRF exception in the CI audit gate — upstream backported the fix, so the exemption lapsed on its own and the allowlist is now empty. dompurify moves to 3.4.13 (shipped, but on a path this app never reaches: no hooks registered, in-place mode unused). js-yaml and nanoid are overridden, both development-only via eslint and postcss. - Patched two build-time frontend dependencies flagged by npm audit (GHSA-r28c-9q8g-f849, GHSA-mh99-v99m-4gvg, GHSA-rgw5-rvv9-x895). --- **Sponsors** Bambuddy is sustainable thanks to people who put their money where their use is. If this release saved you time or kept your farm running, the project runs on recurring contributions — there's no paid tier, no telemetry, no upsell, just sustainable maintenance. - GitHub Sponsors (recurring, 5 tiers from $5/mo to $300/mo) — https://github.com/sponsors/maziggy - Ko-fi (one-time or recurring) — https://ko-fi.com/maziggy	2026-08-15 16:13:31 +02:00
maziggy	907de4d64d	Suppress two Bandit false positives in the new FTP and batch-order tests ... The 1.2.5.3 code-scanning run flagged two new alerts, both in test files added this release, and both false positives.

maziggy	1f3d66e29d	[Feature]: Server-Side Slicing on linux/arm64 systems (#1900) ... * Add override file for ARM64 setups. This commit adds an override file which explicitly specifies the container platform to be linux/amd64. It forces docker to pull/build/run the amd64 image (even on arm64 hosts). Assuming binfmt support is set up, this will run the amd64 applications via emulation. * Add arm64 override file information to README. Adds a section covering the experimental setup for arm64 hosts to the README. * Make the ARM64 override survive the next compose command (#1900) The override only applies while both -f flags are on the command line, and every other instruction in this README is written bare. An ARM64 user who followed the update steps would drop the platform pin without noticing: a manifest error today, and a silent switch off emulation once native ARM64 images ship. The quick start now writes COMPOSE_FILE into .env, so the rest of the file works unchanged on ARM64 -- verified both ways, with and without that line. Two things the setup needs stated where it is read rather than one hop away in the wiki: binfmt has to be registered on the host or the container dies with "exec format error", and emulation costs roughly 3-6x native slice time. Both now lead the section, and the separate-x86_64-box route stays the recommendation it was -- emulation is the fallback for people who have no second machine, not a replacement. The compose file's own header said ARM64 was a dead end. It now points at the override, for anyone who reads the stack instead of the README.	2026-08-15 15:03:46 +02:00
maziggy	e899022116	fix(profiles): read the companion files that hold a preset's real gcode ... A bundled preset can keep a setting in `<preset> template <key>.json`, a file the preset itself does not reference -- the desktop slicer finds it by name. Walking only `inherits` never reached it, so every one of the 56 instantiable BBL machine presets resolved `machine_start_gcode` to the 577-character generic block on fdm_machine_common instead of its own 6.5-21 KB one. That block holds the M620 AMS load and the M1002 gcode_claim_action calls, so a print sliced from it heats the bed, moves the toolhead and extrudes nothing (bambuddy#2838). Companions are now folded into each ancestor as the chain is walked, at that ancestor's precedence, so a caller's own value still wins and the 0.2/0.6/0.8 variants reach their 0.4 sibling's companion. They are found by listing rather than by a fixed set of keys. Covered against the shipped bundle, not fixtures: a new e2e spec resolves all 56 presets inside the image and fails on any that still lands on the generic block.	2026-08-15 15:03:28 +02:00

maziggy	2d324dc7d0	Let API keys read and run slicer pipelines (#1425 follow-up) ... Every pipeline endpoint answered 403 for API keys whatever scopes the key carried. PR A parked all three permissions on the admin denylist until the run dispatch existed to decide about; it landed in PR C and the parking was never revisited. PIPELINES_READ now rides can_read_status. PIPELINES_RUN requires can_queue AND can_manage_library together, so the allowlist gained tuple values: a run slices into the library and then queues prints, and mapping it to either flag alone would hand that flag the other one's authority. The 403 names every flag the key is short of. PIPELINES_WRITE stays admin-only -- a key can run the recipe, not rewrite it or clear the log. Opening the run route also needed the cloud-owner fallback the direct slice route makes: a pipeline can carry Bambu/Orca Cloud presets, and resolving those reads a token off a user record that an API-keyed request does not have. retry_failed forwards the new dependency explicitly, since a direct call receives the Depends marker rather than None.	2026-08-15 15:02:53 +02:00
maziggy	ad2b22dd6b	Remember the Printers page's status and location filters (#2833) ... Pick a location, navigate away, come back, and every printer was showing again. Both filters were plain useState, and the only preferences on that page that were not remembered -- sort order, card size, view mode, collapsed sections and hide-disconnected all persist, each with the same initializer-plus-setItem shape. Give these two the same treatment. A saved filter needs a way out, though. The location dropdown is only rendered while at least one printer has a location, so a saved location that was later renamed or removed would match nothing and take its own dropdown off screen with it -- an empty page and no control to undo it. A location that is not among the available ones now resets to all, and the same for a status the dropdown does not offer. That check waits for the printers query to resolve. The list is undefined while it is in flight, so the available locations start out empty, and acting on that would throw the saved filter away on every page load. Search stays unpersisted: a box that silently refills itself on return is a surprise rather than a convenience.	2026-08-15 15:02:36 +02:00
maziggy	aa4df0c57a	Build the slice output's path from a name a folder can have (#2832) ... A print's display name comes from inside the 3MF, not from the filename, so a MakerWorld title arrives with its punctuation: "Planter Pot with Drip Tray, 12 cm / 5 inches". The slice-to-archive sink used it verbatim for the output folder and the output file, and a slash in a folder name is not a character -- it is another folder. mkdir(parents=True) created the level it implied and the file's own join added a third that nobody had made, so the slice failed with ENOENT on a path that half existed. Renaming the print first was the only way through. Reduce a display name to a single path component before it becomes one. Characters a name cannot hold are replaced rather than dropped, so the folder still reads like the model's title, and the set is the one the SD card already rejects -- which covers a Windows install too, where the colon in "Model: v2" fails the same way. The name shown in Bambuddy is untouched: a title is allowed its punctuation, and refusing the slash would reject the name this was reported about. The joins are asserted to stay under the archive directory. That was already claimed by a SEC-PATH-OK marker on both lines, citing a sanitiser that is defined in another module and was never called here; without the marker the path-join backstop flags them both. The claim is now true, and a future edit that reaches around the reduction is caught rather than trusted. The library sink takes the same embedded name, so it gets the same reduction: managed storage names the file after a UUID and never saw this, but an external folder writes the name as given. Display names are also stripped of control characters on the way into the database, in the schema and in the archive service. The validator hands back anything that is not a string rather than iterating it, so the field still answers a list or a bare int with a 422 instead of accepting the one and failing on the other. Display names are also stripped of control characters on the way into the database, in the schema and in the archive service, cleaned before the filename fallback rather than after it so a whitespace-only embedded name still falls through to the filename. The validator hands back anything that is not a string rather than iterating it, so the field still answers a list or a bare int with a 422 instead of accepting the one and failing on the other.	2026-08-15 15:02:17 +02:00
maziggy	dde724f83c	Repair no-3MF archives' photos and their silent filament writes (#1820) ... Two faults behind the same kind of print: one that arrives without a retrievable 3MF, which on an H2S is any job started from the printer's own internal library. Such an archive has no file_path, and Path("").parent is Path("."), so every site that derived the archive's folder from it landed on the data directory itself. The finish-photo capture spotted that and wrote to <archive_dir>/<id>/photos instead. Nothing else did. The photo was written in one place and looked for in another: reads 404'd, deletes dropped the name and left the file, and the notification attachment never found the image. Hand-uploaded photos worked only because upload and read agreed with each other rather than with the capture. Give the question one owner in utils/archive_paths and have all four sites ask it. Lookups check the old shared location too, so photos already uploaded there stay reachable; uploads now go where captures go. Separately, the remain%-delta fallback that stands in for a missing 3MF can charge nothing for several reasons, and did so without a word. The AMS reading is coarse and, on the reporter's printer, noisy: it rises mid-print, swings five points over a job, sits at 100% through a 36-minute print on a fresh spool, and goes negative on a nearly empty one -- which the start-of-print gate rejects, dropping the only slot that was printing. Two of their prints went uncounted for two different reasons and both read as "no spools updated", which is also what a print with nothing to charge prints. Name the slot and the two readings in each case, on the Spoolman path and on the internal-inventory path, which has carried the same gates since #1119. The Spoolman path also had no notion of which slots the print used, so a spool swapped into an idle slot mid-print reads as consumption and is billed to whoever that slot is assigned to -- the fault #1269 fixed for the internal tracker, still open here, and likeliest on exactly the prints this fallback serves, where nothing else narrows the field. Use the same three pieces of evidence it does: the print's mapping, its mid-print tray changes, and the tray it started on. The last needs storing, because the internal tracker's row is deleted before this runs and a screen-started print has no mapping to fall back on -- hence a new nullable column, and no backfill, since a row from before it existed has nothing to say. Where no evidence exists at all, every slot is still considered. Both paths also treated tray_now == 255 as naming a slot. It does not: it is the field's initial value, the fallback for an unparseable reading, and what it reports with nothing loaded. Mapped as a tray id it becomes (255, 1), so as the only evidence it excluded every real slot and charged nothing at all -- this issue's own bug, arriving by a new route. On the internal path that is live today; on the Spoolman path it would have shipped with the guard above. The external holder reports 254 when it is genuinely in use. The arithmetic is untouched: at one percent per step this cannot resolve a small print, and pretending otherwise would be worse than saying so.	2026-08-15 15:01:42 +02:00
maziggy	15eace71d6	Show the plug that powers the printer in the card's Power row (#2830) ... A printer card has one Power row: a plug name, its draw, and the auto-off and on/off buttons. Which plug filled it was decided by nothing -- the endpoint returned the first row the database handed back that was not a Home Assistant script, from a query with no ORDER BY. For the reporter that was an enclosure exhaust fan, added before the outlet their X1C is plugged into. The card showed the fan's name with '--' for watts, offered to switch the printer off by cutting the fan, and demoted the metered outlet to the small HA button row. The fan was marked as not powering the printer and hidden from the card; neither setting was consulted here, though controls_printer_power has decided the scheduler's power-on pick since #2629. Rank the candidates instead: switchable at all, controls_printer_power, enabled, show_on_printer_card, reports power, lowest id. The first rules out a script, which can only be run, and an MQTT plug, which the control endpoint rejects as monitor-only -- and an MQTT plug is exactly the kind that reports watts, so without it ahead of the power tiebreak the row could land on a plug whose on/off button answers with an error. The last is not cosmetic: with no ORDER BY, a plain UPDATE on PostgreSQL can move a row and silently swap which plug the card calls the printer's power. None of these excludes a plug. A printer whose only plug is hidden, disabled or monitor-only still needs its Power row, because that row holds the on/off button and the HA buttons are drawn inside it. controls_printer_power sits above show_on_printer_card because the two only disagree when the plug that really feeds the printer is hidden, and letting a display preference win there points the power buttons at an accessory -- the fault #2629 fixed. Power capability is read from the configuration, not measured: this runs on every card render, and it is approximate both ways, so it only breaks a tie. The scripts endpoint shares the same pick and excludes it, so a switchable main plug is not repeated as a button directly below itself. A script is left in place: a printer whose only entities are scripts falls back to showing one in the power row, and taking it out of the button row too would cost it the one-click run it has always had.	2026-08-15 15:01:19 +02:00
maziggy	46aa6affd3	Match a print completion to its queue job the way the printer names it (#2829) ... Bambuddy has no run identifier to tie a completion to a queue row, so it finds the row by printer and status='printing' alone. b5a34b7ba added a check that the completion's subtask name agrees with the file the row was dispatched with, so the printer's own calibration runs cannot close someone's job early. It compared the two names verbatim. The printer does not echo them verbatim. It substitutes underscores for spaces, so 'H2D_Carbon_Filter_(V2)_Body & Solid Lid' came back as 'H2D_Carbon_Filter_(V2)_Body_&_Solid_Lid', the check refused it, and the row stayed printing. check_queue counts every printing row as a busy printer and nothing else ever closes one, so the printer's queue stopped until someone cancelled by hand. It also truncates long names and marks the cut with '...', which would have done the same to any long title. Compare on the canonical form instead -- case, spaces and underscores -- which is the rule the 3MF lookup in this module has always used for the same names, and treat a truncation marker as a prefix match. The check keeps its purpose: the same printer the same day correctly refused a completion for auto_pa_line_calib_mode. One comparison being stricter than reality should not be able to stop a queue indefinitely, so the scheduler now closes a row itself when it has been printing for five minutes after its printer went terminal, with the status that state implies. A real completion arrives within seconds, so this only sees rows that were already stranded, and a disconnected printer never qualifies. It restores the queue only -- notifications, billing and auto-off are not replayed minutes late.	2026-08-15 15:01:00 +02:00
maziggy	2548a5d49d	Show the printer card thumbnail again after navigating back to the page (#2826) ... The cover URL is cache-busted on the print name, which does not change while a print runs. Leaving the printers page and returning therefore re-mounts with a byte-identical src, which the browser serves from its in-memory cache with no network request -- which is why the reporter's network panel was empty while the placeholder sat there. `loaded` could only ever be set by onLoad, and a mount effect reset it to false unconditionally. For a cache hit those are two racing tasks with no ordering between them: when the load event won, the effect undid it, and nothing put it right afterwards because the URL does not change again for the rest of the print. Read the element's own complete/naturalWidth in that effect instead of assuming nothing has loaded. That settles it whichever task wins, and also covers the variant the reporter proposed, where the handler is not live in time. Being a race explains why it reproduced 100% for the reporter and not at all here. Only the printer card was affected; archive thumbnails build a fresh URL every mount, so they always hit the network. CoverImage is exported so the regression tests can mount it directly.	2026-08-15 15:00:42 +02:00
maziggy	b83eea07cd	Explain a print that never reached the printer's card, instead of sweeping for it (#2780) ... Bambuddy reads a print's 3MF, cover and timelapse over FTPS on port 990, which on every Bambu model serves external storage only. Under some configurations H2-series and P2S firmware keeps the sliced file on internal storage, where Bambu Studio put it over the port-6000 service, and then no path on 990 can find it. The print command has always said which of the two it used -- `url` reads ftp://<name> or brtc://emmc/<name>. We discarded it and swept anyway: ~110 connections per print, all certain to fail, ending in an archive card with nothing on it and no stated reason. In the reporter's bundle all 35 dispatches to their H2C and P2S said internal storage, all 25 to their X1C said external, and all 44 empty cards belonged to the first two. Read the field, skip the sweep when it cannot succeed, and record which reason applied. A printer that uses the card is unaffected, and so is one we have no answer for -- silence is not evidence, and reading it as bad news would break archives that work today. The answer is held per print and dropped when that print ends, rather than kept as a standing fact about the printer. Plenty of prints never announce themselves: 14 of the 79 print starts in that bundle arrived with nothing on the request topic, started from the printer's own screen or picked up after a restart. Left standing, one slicer print to internal storage would suppress the lookup for every screen-started print after it, on a printer whose files really are on the card. The sticky reading is kept for the connection diagnostic alone, which is run after the print that prompted it and would otherwise have nothing to report. Two things that pointed the wrong way go with it. The archives banner told everyone to enable "Store sent files on external storage"; the reporter had it on for the whole three weeks and it would not have helped. The diagnostic passed a printer whose slot was empty, because it read only the toggle -- an empty slot is now a failure naming the slot, and a printer that has storage and still used its own is a warning. On P1-series that empty-slot failure yields to the existing unsupported-model skip: the toggle cannot be switched on there at all, so telling the operator to insert a card would promise a fix inserting a card does not deliver (#2524). Also close FTP sockets on the failure paths, which dropped them for the garbage collector -- 1813 in a day in that bundle -- and drop the advice to restart the printer, which the reporter tried twice while a single manual connection to the same printer handshook cleanly. This does not make the affected prints archive in full; that needs the port-6000 protocol tracked in #2762.	2026-08-15 15:00:16 +02:00
maziggy	8e553289db	Choose which rack nozzle each filament prints from on an H2C (#1784) ... The Vortek rack holds six hotends, and a multi-colour plate is sliced to use a different one per colour so it can skip the purge. Which of the six each colour takes is not in the 3MF. The same plate, sliced and sent twice from Bambu Studio with a different choice each time, produces two files that differ only in rounding in the last digit of a few extrusion figures -- the filament grouping, the toolchange stream, the 120 nozzle-change markers and project_settings.config are all identical. The choice travels only in the dispatched nozzle_mapping. Bambuddy had no way to state it, so those plates went out with no nozzle assignment at all and the printer chose for itself. That is what levelled on one hotend and printed with another, millimetres above the plate. Every rack-bound filament now carries a position picker beside its AMS slot dropdown, listing all six with the nozzle each holds. An empty position, or one holding the wrong diameter or flow type, is shown greyed out with the reason rather than hidden, so someone looking for position 4 finds it. The choice is per filament *group* rather than per slot, because a group is one hotend: two filaments the slicer grouped together share it and cannot point at different positions. Nothing has to be picked. Positions are assigned automatically, preferring one already loaded with that colour, which on the plate this was built against reproduces Bambu Studio's own pick exactly. A nozzle currently picked up onto the carriage is offered too. The firmware drops its rack position from the report entirely rather than sending a placeholder (#943), and refusing it would rule out the position most likely to be wanted -- the one the last print left mounted. Only recoverable when exactly one position is missing; two gaps are genuinely ambiguous and stay unavailable. Positions are re-checked at dispatch, not just when queued, because the rack can be re-loaded in between. The two failure modes differ on purpose: an explicitly chosen position that no longer fits stops the print, names what the position now holds, and deletes the uploaded file from the SD card so it cannot be started by hand either -- an operator who named a hotend must not silently get a different one. An automatic assignment that cannot be made instead falls back to letting the firmware choose, which is what happened before any of this existed. The pick is stored as {group: position} rather than as the expanded nozzle_mapping, though that is what goes on the wire. That column means "Bambu Studio decided, forward verbatim", and only the group-and-position form can be re-checked against what is actually mounted at dispatch. The existing multi-rack refusal in extract_nozzle_mapping_from_3mf stays. It still guards the #2800 fallback, which can only ever name one rack id. Measured on the maintainer's H2C: rack position n is physical nozzle id 15 + n, confirmed by cross-referencing two captured dispatches against Bambu Studio's own dialog. extruder_max_nozzle_count names which carriage is the rack straight from the file, and is read rather than assumed -- a fourth independent confirmation of the carriage indices fixed in 45dc139. The print dialog is also wider, on every printer. Its filament rows carry the most horizontal content in it and adding a picker truncated names to "Bamb...". The column widths themselves only change on a rack machine. Tests: 44 unit covering the plan, the resolver, the mounted-nozzle recovery and every refusal; 9 dispatch integration asserting the two real captures end to end; 7 API round-trip; 33 frontend. The API ones exist because two integration bugs got through a green suite that tested the pieces and not the seams -- the group data reached only one of the three filament-requirements routes, and the field was declared on every schema except the create one, where Pydantic dropped it in silence.	2026-08-15 14:59:41 +02:00
maziggy	7787b3fc0f	Grow the H2C nozzle rack with the printer card size ... The six rack chips were a hard-coded 28 pixels at every card size, while the body type and icons around them scale by 20% at L and 40% at XL. Set the card larger and the rack stayed put -- a shrunken strip beside neighbours that had grown around it, with the diameter figures pressing against the edges of chips that had not moved. The chips now read their size from the same scale as everything else, which needed one new rung: the icon tokens run in quarter-rem steps (i2 is 8px, i3 12, i4 16, i5 20), so 28px is i7. S and M are unchanged, as they are for every other property that control scales. The card is sized to its contents, so it simply takes the extra width rather than being told a new one -- and at L and XL that row has the room to give, so the temperature readings beside it do not go back to wrapping. Two tests: one pins i7 to 33.6px at L and adds it to the sweep asserting every token is set at XL, the other asserts the chip reads the token, so a revert to a fixed class fails rather than silently regressing.	2026-08-15 14:59:19 +02:00
maziggy	58594c60c9	Print an H2C two-nozzle plate from the carriage it was levelled on ... The two carriages were the wrong way round: extruder index 0 was treated as the fixed hotend and index 1 as the swappable rack, and it is the other way about. A plate using both was levelled with one nozzle and printed with the other, several millimetres off the plate. Three sources agree, and disagreed with the code. Telemetry reports ams_extruder_map {'0': 1, '1': 0, '2': 0}. BambuStudio, dispatching a plate that used all three of those AMS units, sent the filament from the unit on extruder 1 to physical nozzle 1 and the ones on extruder 0 to rack positions 16 and 18, and that print completed. And the two constants could not both have been right: _FIXED_NOZZLE_ID is 1 while the fixed extruder was 0, in a scheme where physical nozzle id N sits on extruder N. The old value came from the #2800 hardware A/B, where [17, -1, -1, 1] printed in mid-air and [1, -1, -1, 17] printed correctly. That result stands -- it established which wire worked. The extruder indices were not measured by it; they were inferred by pairing the working wire with a slot_extruders list produced by the 3MF reader that has since turned out to mis-read exactly these files. The reasoning is recorded at the constants so a future regression report is not re-litigated from scratch. Also withholds nozzle_mapping entirely when more than one filament group needs the rack. Two groups on one extruder means that extruder is a rack and the plate wants a different hotend per group -- which physical slot each takes is the slicer's choice against the live rack and is stated nowhere in the file, since both groups can carry identical diameter and nozzle type. Studio dispatched such a plate to 16 and 18; nothing here can reproduce that, and answering anyway is what printed in mid-air, so the firmware picks. Restores the fixed 32-entry padding that dfeac792f replaced with the plate's slot count. That was derived from a single 3-entry capture which turned out to be a calibration job; Studio's dispatch of a real project print on the same machine is 32 entries. Both constants are read in one function, on the nozzle-rack path, so no other model is affected. Verified on hardware: the plate that printed in mid-air now prints.	2026-08-15 14:59:02 +02:00
maziggy	3ce4ecfcf7	Report a print stage we cannot name at the default log level ... STAGE_NAMES is hand-maintained and every new model adds to it, so a printer occasionally reports a number that is not in it and the card reads "Unknown stage (72)" -- which an H2C did, where the table runs to 66 and then jumps to 74. Stage transitions were logged only at DEBUG, off in normal running, so the sole record that it had happened was the card itself, and by the time anyone looked the printer had moved on. The asymmetry is the point: a stage we can name is worth DEBUG, and the one we cannot is the interesting one. An unnamed stage is now logged at INFO, once per stage number per session, with the model, the stage it came from and the print state at the time -- which is what naming it afterwards needs. Named stages are unchanged, so a normal print logs nothing new. -1 is excluded: it is Bambuddy's own "not in a stage" sentinel and the field's initial value, so every print would otherwise report it on the way out of its last real stage. Fixes a latent crash found while testing this. The stage-change log line builds its text before the log level is consulted, so get_stage_name runs on every transition whatever the level is set to; a stg_cur that was not hashable -- malformed telemetry rather than an unknown stage -- raised TypeError out of STAGE_NAMES.get and aborted the whole state update. Labelling a value can no longer do that.	2026-08-15 14:58:45 +02:00
maziggy	c5cd0dbe77	Stop an H2C refusing a multi-colour print as a hotend mismatch ... The print uploaded, the printer took the command, and stopped at once with HMS 0500-4047 -- "the available hotend quantity or model does not match the sliced file". nozzle_mapping told the printer one of the plate's filaments went to no hotend while ams_mapping named the tray it comes from, and the firmware will not start a job on that contradiction. Each filament in a 3MF names the group it belongs to, and on every other dual-nozzle Bambu the group number is also the extruder index, so it was read as one. On a rack machine it is not: the rack carriage holds six hotends to the fixed carriage's one, so the slicer writes a group per nozzle rather than per carriage. The failing plate carried groups 0, 1 and 2 against a two-entry physical_extruder_map, and the filament in group 2 was dropped -- indistinguishable downstream from a slot the plate does not print, which is what reached the wire as -1. extract_nozzle_mapping_from_3mf now resolves the group through the table the file states for itself, the <nozzle id extruder_id> elements in slice_info.config. Files carrying no such table keep the direct index, so H2D slices are unaffected. A filament that still cannot be placed drops the whole mapping with a logged reason instead of half an answer: the firmware then picks its own nozzle, which is the pre-existing behaviour and far better than an answer that contradicts itself. Two related faults fixed in the same pass. The mapping was read across every plate in the file, so on a multi-plate project a slot took its extruder from whichever plate came last; it is now scoped to the plate being dispatched, in extract_filament_requirements as well. And the array is now one entry per filament slot, matching BambuStudio's own dispatch of [1, 16, 16] for a three-filament plate, rather than padded to a fixed 32. Verified against the file that failed: slot extruders [-1, 1, 0] became [0, 1, 0], and the wire [-1, 16, 1, -1 x29] became [1, 16, 1].	2026-08-15 14:58:27 +02:00
maziggy	1b944739d2	Size the H2C nozzle rack card to its contents and number its slots ... The rack card shared a row with the nozzle, bed and chamber readings but was set to flex: 2 1 190px -- a 190px floor plus twice their growth share -- to draw six fixed 28px chips. On anything wider than a compact card it claimed several hundred pixels and left most of them empty, and the width came out of the cards that needed it: the combined dual-nozzle reading was wrapping "220 / 220" onto two lines beside a mostly blank rack. It is now flex: 0 1 auto, so it takes its content width and gives the remainder back. Shrink stays enabled so it still gives way on a narrow card instead of overflowing. Each slot also carries its physical rack position 1-6 below the chip, so a nozzle can be named rather than counted along. The numbering is positional -- an empty slot keeps its number -- so "the nozzle in slot 4" means the same thing however many of the six are occupied. The #943 regression test read every span in the slot row, which the new number spans would have interleaved with the diameters; it now matches the diameter spans specifically. A second test pins the 1-6 labelling across a rack with empty positions.	2026-08-15 14:58:09 +02:00
maziggy	12a34448f9	Rank near-colour matches by how they look, and share one filament type table (#2804) ... Three follow-ups to #2804, all bearing on one decision: which spool a print uses when the exact colour is not loaded. Colour ranking is now perceptual. The ranking added in #2804 measured RGB distance, which rates a colour by how far apart the numbers are rather than how far apart they look, and it overweights blue badly enough to invert the answer: against a required #1E4821 green, a purple #38202F is the nearer of two eligible spools by RGB and four times the further once measured properly. Both sides now use CIEDE2000 -- perceptual_color_distance in backend/app/utils/color_utils.py and colorDistance in amsHelpers.ts, kept structurally identical so they can be read side by side. Verified against the Sharma/Wu/Dalal published reference set, all 31 pairs to 1e-4, and the two implementations agree to within 1e-9 across 800 sampled pairs. Eligibility is untouched, still the per-channel RGB box, so this only reorders spools that already qualified. Type matching now agrees between the interface and the scheduler. Bambu firmware treats PA-CF, PA12-CF and PAHT-CF as one material and the scheduler has always matched them accordingly, but the interface compared raw type strings and called that same pairing a mismatch. The badge contradicted what the printer was about to do, and the manual override picker, which groups by canonical type, offered the very spool the badge then rejected. The fifteen comparison sites in useFilamentMapping.ts, useMultiPrinterFilamentMapping.ts and PrinterSelector.tsx now call filamentTypesCompatible. The pipeline pre-flight reads the matcher's table instead of its own copy. That copy had drifted into disagreeing in both directions: it aliased PLA Basic to PLA where the matcher never has, so a run could clear the check and then fail to map its slots, and it lacked the nylon grouping, so it flagged runs the matcher handles without complaint. A check whose job is to predict dispatch is wrong whenever it disagrees with dispatch, whichever way it leans, so it and the scheduler now both read backend/app/utils/filament_types.py. That canonicaliser deliberately does not strip surrounding whitespace. It looks like a free improvement, but it would collapse a junk tray_type to "" just as a 3MF declaring no filament type yields "", and a typeless requirement would start matching a junk-typed tray instead of reporting the slot unmapped. Padded type strings are worth handling on their own terms, with that case addressed. One behaviour change outside the ranking: the pre-flight is stricter for a printer reporting a product name such as "PLA Basic" where the generic material belongs, which it now flags rather than passes. Rare in practice, since the printer reports material and product name in separate fields, and it is the answer the matcher would give. Nothing about which spool a print actually uses changed outside the colour ranking itself. Adds 203 backend and 6 frontend tests. The #2804 tie-break test now uses identical colours: two colours at equal RGB distance are not perceptually tied, which is rather the point.	2026-08-15 14:57:41 +02:00
maziggy	292b1b416b	Pick the nearest eligible filament colour instead of the first one in tray order (#2804) (#2823)	2026-08-15 14:57:14 +02:00
maziggy	3031e52ddf	fix(slicer): stop a 3MF from switching off supports its process preset turned on (#2820) ... --load-settings is authoritative, so since #1881 four support fields travel the other way -- enable_support, the two filament slots, and support_type -- lifted out of the source 3MF and written over the picked process preset. Bambu's shipped presets all set enable_support: 0 because supports are a per-print decision, and without the carry a project exported with PVA in the interface slot sliced single-material. But the carry ran in both directions, and the off direction is the one nobody asked for. Nearly every published model ships with supports off, so slicing one against a custom preset that deliberately enabled them stripped them back out. The reporter's preset sets enable_support 1, support_type normal(auto), support_style snug; the slice came back disabled and tree(auto). Only the style survived -- it is not one of the four carried, and they had re-entered it in the slice dialog. The source can now switch supports on, never off. Nothing is lost: every shipped preset has them off, so a preset that has them on is a deliberate choice by whoever wrote it, and a file that wants supports still gets them with its slot assignments. A file that never declares enable_support is treated as off -- no intent to act on. The truthiness rule ("1", true, 1, and the forks that write neither) now lives in one place as supports_enabled_in_config(), shared with extract_support_filament_slots_from_3mf, which had it inline. Also log the carry with the fields it took. The slice dialog shows the picked preset's values, so a carried field silently disagrees with what was on screen and this step logged nothing at all -- the report chased an unrelated sanitiser line about the source file's own settings, which was the only thing in the log that mentioned any of these keys.	2026-08-15 14:56:58 +02:00
maziggy	558159c95c	fix(queue): stop a library-file delete from destroying the jobs queued against it (#2819) ... Nothing tied a library file to the queue rows pointing at it, and the FK that describes the relationship is ON DELETE CASCADE -- which SQLite does not enforce and PostgreSQL does. So the same fault had two faces: rows left pointing at a file that no longer existed, failing at the printer with "Library file not found" days later, or rows deleted outright with no error and no history. Two routes into it, both fixed by taking the queue off the file before the row goes. Dispatch (the reported case): quantity>1 on the printer-card upload-and-print flow puts cleanup_library_after_dispatch on every copy, and _clone_queue_item copies library_file_id onto batch clones, so the first dispatch consumed the file the rest were waiting on. The copies are now pointed at the archive that dispatch just created -- it holds its own copy of the 3MF -- and the consume flag is cleared on them. A copy already printing from its own archive keeps it, a finished one keeps its outcome, and a cross-model item (#671) keeps any candidate this does not consume. Deletion: the File Manager, bulk delete, folder delete, emptying the trash and the retention sweeper all removed rows with queued work against them. Folder delete did not even clear the cross-model candidates, because the file-id walk it already performs threw its result away. Jobs waiting on a deleted file are now cancelled at that moment, naming the file, and every other row referring to it is detached rather than destroyed -- print history and batch progress are counted from those rows. A job that is printing is left alone: what is deleted is the library copy, not the copy on the machine. The trash is reversible so it still changes nothing about the queue, and a job dispatched while its file is in the trash now says so instead of "not found". Verified row for row on PostgreSQL 16 as well as SQLite: without this, PostgreSQL deletes every queue row referencing the file.	2026-08-15 14:56:41 +02:00
maziggy	03ec2aef4d	fix(ui): stop the Spool Inventory header from scrolling the page sideways (#2813) ... Five header buttons in a row that could neither wrap nor shrink came to ~600px, so on a 390px screen the header ran past the viewport and took the whole page with it -- <main> is the scroll container, so everything inside it panned. Stack below sm and wrap the actions, matching the pattern the Statistics, Settings and Archives headers and this page's own filter bar already use. Identical at >=640px. The System Information header had the same construction with one button and gets the same treatment.	2026-08-15 14:56:24 +02:00
maziggy	3ac289fccb	Attribute filament correctly when AMS backup swaps spools mid-print ... Everything the completion path needs to split a print's filament across the trays it fed from lived only in memory: the dispatched plate and slot-to-tray mapping, the spool-assignment snapshot, and the tray-change log. A print that outlived a restart lost all of it and fell back to what the printer reports at completion -- which, with AMS Filament Backup on, is the substitute tray. The whole print was charged to the spool that only finished it while the spool that ran dry was charged nothing. Persist that context in a new active_print_sessions row, append tray changes as they happen, and restore both the session and the printer's tray-change log at restart recovery. Seed the log from the current tray when there is nothing to restore, since last_loaded_tray advances even when no change is logged. Rank the queue item's stored ams_mapping above the printer's live mapping field, which is what backup rewrites. Recover plate_id from the archive or queue item, and give extract_layer_filament_usage_from_3mf a plate_id instead of taking the first .gcode member -- a Bambu Studio export stores plate 2 first, so per-layer figures were measured against the wrong plate for both inventory backends. Stop auto-unlinking a spool assignment when its slot reports empty during a running print. At a runout the spool is still in the AMS, and dropping the link leaves the completion path nothing to charge. Capture the print-start context for both inventory backends. Spoolman's own durable row (#1820) carries its plate-scoped figures and dispatched mapping but not the tray-change log, and its slot assignments -- the way. Registration in _active_sessions stays gated, since on_ams_change reads it to decide whether to skip the remain%-based weight sync (#880).	2026-08-15 14:56:04 +02:00
maziggy	0cdc9944a4	Do not close a queue item on a completion for another print ... on_print_complete finds the row to close by printer and status='printing' alone. The MQTT payload carries a subtask name but no run identifier, so nothing tied the event to the row: any completion delivered for a printer closed whichever job was printing on it. A job closed that way is marked completed while the printer is still working, leaves the queue for history, and strands the rest of its batch, because the queue correctly refuses to dispatch onto a busy printer. The handler now checks the completion against the file the row was dispatched with, recovered from its archive, and leaves the row alone when they disagree. Only a positive disagreement refuses: no archive, no file name or no subtask name is unverifiable rather than wrong, and refusing those would strand the item in 'printing' and wedge the queue -- the failure the loose lookup was avoiding in the first place. This surfaced through the test suite, which could reach a real database. conftest built its own SQLite engine, but core/config.py snapshots DATABASE_URL at import time and core/database.py builds the module-level engine and async_session from it. Tests reaching code that opens its own session -- run_with_retry, which the completion path uses, takes its sessions from core.database and so is untouched by the widespread patch("backend.app.main.async_session") -- therefore talked to whatever database .env named: the developer's own SQLite file on a plain checkout, a live install with a PostgreSQL .env. DATABASE_URL is now redirected to a throwaway file before any app import, and the run aborts rather than starts if that did not take.	2026-08-15 14:55:45 +02:00
