The filament list is positional from the modal down to the CLI's
filament_N.json parts, but for a source that already carries slice_info the
requirements endpoint returns only the slots the plate consumes. A
MakerWorld model declaring four filaments and painting with slot 4 alone
therefore showed one dropdown, whose PETG pick the CLI bound to slot 1 —
slot 4 sliced with the profile baked into the source, and the print came out
PLA.
The endpoint now takes full_slots, which widens that answer to every
project slot with used_in_plate flags, and only the slice modal passes it.
Print-time AMS matching shares the endpoint and keeps the used-only list, so
it still asks for exactly the spools the job needs.
Telegram groups with Topics enabled always received notifications in the
General topic, since only Bot Token and Chat ID were configurable. Splitting
notifications per printer meant running a separate chat for each one.
The Telegram provider now takes an optional Forum Topic ID - the last number
in a topic's link, t.me/c/1234567890/25 - and routes its messages there. Left
empty, nothing changes.
The value is coerced to an int once in _send_telegram and attached to both the
sendMessage JSON body and the sendPhoto form data. That ordering matters:
Telegram rejects a string message_thread_id in the JSON body while accepting
one in the multipart call, so passing the raw form value through would have
worked for thumbnail notifications and 400'd for plain-text ones. A
non-numeric value is rejected in the form and again server-side before any
request goes out.
No migration - provider config is a JSON blob.
Adds Forum Topic ID plus help text to the Telegram section of the provider
dialog, translated in all 13 locales. Backend tests cover omitted / blank /
int-typed / non-numeric values and both send paths; frontend tests cover the
field being optional, absent for other providers, round-tripping on save, and
blocking save on a bad value.
Published models often deviate from the stock Bambu profile on purpose -
five walls, 100% infill, a 0.1mm first layer. Re-slicing one for a
different printer discarded all of it: the picked process preset
overrides the file's embedded settings, and that override is precisely
what makes cross-printer re-slicing work, so it cannot just be dropped.
"Slice as designed" (#2611) does not help - it is all-or-nothing and
only offered when the picked printer already matches the design's
target.
The deviation list does not have to be computed. Bambu Studio writes it
into the 3MF as different_settings_to_system, laid out as
[process, *filaments, printer] - verified against real files at 2, 3 and
4 filament slots. The parser refuses any file whose array length
contradicts its own filament count rather than guessing an index, since
reading the printer slot as the process slot would carry the designer's
machine_start_gcode onto a foreign printer.
The slice dialog now lists exactly which print settings the author
changed and what each was set to, with a checkbox per setting. Design
intent - wall count, infill, layer and first-layer height, supports,
seam, brim, ironing - is ticked by default. Printer-specific values -
speeds, accelerations, jerk, fans, temperatures, prime-tower geometry -
are listed with a badge but start unticked: tuned for the author's
machine, they can be merely wrong on the target or outside the range its
profile accepts, which fails the slice outright.
Only ticked keys are sent, and only keys the source actually flags as
changed are applied. Values are written into the outgoing process JSON,
the same mechanism the support carry-over has used since #1881: for a
Standard preset pick that JSON is an inherits stub, so the patch is the
child in the chain and wins over the flattened parent. Process slot
only - filament picks are honoured as chosen.
The wiki's "this is not a settings merge" note under Slice as designed
described the gap this closes; rewritten to point at the new panel.
Translated in all locales; wiki updated. Covered by backend and frontend
tests.
When a print reaches a terminal state Bambuddy holds the queue until
someone confirms the build plate is clear. That gate was visible only in
the Web UI: the printer's own MQTT push reports nothing beyond RUNNING,
PAUSE, FAILED, FINISH and IDLE, so an external automation could not tell
"finished" from "finished and still waiting for a human".
The per-printer status topic now carries an awaiting_plate_clear field,
and every transition is additionally published on a new retained topic,
bambuddy/printers/{serial}/plate_clear. Retained, and published from the
flag itself rather than from printer telemetry: a subscriber learns the
state of every printer the moment it connects, and the state stays
correct after Auto Off powers a printer down - telemetry stops there,
which would otherwise leave the status topic frozen at false.
Publishing is edge-triggered. The queue clears the gate on every
dispatch whether or not it was up, and no subscriber should see a
"plate cleared" for a plate that was never dirty. Persistence and the
WebSocket broadcast stay unconditional; they are idempotent and predate
this.
A matching Plate Clear Required notification event was added, off by
default on every provider because it fires after every print at the
same moment as the print-complete alert. Only the rising edge notifies.
Acknowledging still goes through POST /printers/{id}/clear-plate.
Two tests in test_printer_manager_status_broadcast.py asserted
_schedule_async.call_count == 2 for the setter. The new emission makes
it three on a transition, so they now assert that the persist and
broadcast coroutines are actually scheduled - which is the contract

frontend tests.
A spool created by Quick Add, a CSV import or an RFID scan has no slicer
preset, brand or subtype. Reopening it in Edit Spool demanded all three
before anything could be saved, so changing its storage location, cost
or notes was impossible - and Copy Spool had the same gate with no Quick
Add toggle to waive it. The preset you were then forced to pick auto-
filled material, brand and subtype from the preset name, silently
rewriting a hand-entered manufacturer (Elegoo -> Generic) so the spool
no longer appeared where it had been filed.
Editing and copying now require only what the backend requires: the
material. Preset, brand and subtype stay fully visible and editable -
nothing is hidden the way Quick Add hides it - and the required-field
markers no longer advertise a rule that isn't enforced. Selecting a
preset fills only fields that are still empty or that a previously
selected preset had filled, so values the user (or the saved spool)
provided survive; switching between presets still replaces what the
earlier one contributed.
The brand and material dropdowns also no longer filter themselves down
to the brand/material pairs known to the color catalog and slicer
presets. Elegoo is catalogued only for PLA, which made a real product
like Elegoo ASA look impossible to enter. Both lists now always offer
everything known, with paired entries ranked first under Suggested and
the rest under All, and a spool's own custom brand or material is always
present in its own dropdown. The SpoolBuddy write-tag form shares these
fields and gets the same treatment.
Lastly the Quick Add layout no longer leaks out of create mode: quick-
adding a spool and then opening Edit left the edit form in the reduced
layout with no toggle to leave it, because the toggle is create-only.
Frontend only. Translated in all locales; wiki updated. Covered by
validation and form-interaction tests.
The live Obico classification was only visible under Settings ->
Failure Detection, so tracking how detection matched an ongoing print
meant flipping between the Printers screen and Settings.
Each printer card's badge row now shows an AI badge whenever detection
is enabled for that printer, like the other health badges: gray Idle
while no print is being watched, then green Safe, amber Warning, or
red Failure while a print is actively monitored. The tooltip carries
the current smoothed score; clicking jumps to the full detection
status and history in Settings. Printers excluded from the monitored
subset show no badge.
Served by a new lightweight /obico/printer-status endpoint readable
with printer permissions alone - it exposes only the enabled flag, the
monitored-printer set, and per-printer classification, keeping ML URL
and other configuration behind the existing settings-gated endpoint.
Bark is the open-source, account-free iOS push app (self-hostable
via bark-server). Configure with just the device key from the app;
the server URL defaults to the official api.day.app relay and
accepts a self-hosted instance. Optional settings: notification
Group, Sound, and iOS Interruption Level - Time Sensitive breaks
through scheduled summaries, Critical bypasses Silent mode and
Focus, Passive delivers silently.
bark-server can wrap failures in an HTTP 200 body ({"code": 400}),
so the sender checks the body code as well as the HTTP status.
Unknown interruption levels are dropped rather than forwarded.
When an HA notification provider targets a notify service (e.g.
notify.mobile_app_myphone), a new optional Data (JSON) field is
forwarded as the service call's nested "data" object - the same
place HA automations put mobile push options like priority, ttl,
channel, and group. ttl: 0 + priority: high make Android pushes
arrive immediately; channel gives printer alerts their own sound.
JSON rather than key=value lines so numbers stay numbers and nested
options work. Validated on both ends: the UI rejects malformed JSON
before saving, and the sender fails loudly instead of posting a
half-built payload. Only included when configured - the default
persistent_notification.create path is unchanged, as its schema
rejects unknown keys.
The Most Expensive record on the Statistics page ranked prints by
filament cost alone, ignoring the per-print energy cost Bambuddy
already measures via an attached smart plug. It now ranks by
filament + measured energy cost; prints without smart-plug data
compete on filament cost alone, as before.
Filament Trends gains an Energy Over Time chart: kWh per day (per
hour for ranges of a week or less, per week for long ranges), with
the range's total kWh and energy cost in the header. The chart only
renders when the selected range contains measured energy data, so
setups without smart plugs see no change.
The /archives/slim stats feed now carries each run's energy_kwh /
energy_cost from print_log_entries. Translated in all locales.
Covered by backend and frontend tests.
The Edit Spool "PA-Profil" tab and the SpoolBuddy write-tag page fetched a
printer's calibrations with getKProfiles(printer.id), which defaults the nozzle
filter to 0.4. The printer/MQTT layer filters strictly by that diameter, so on
a multi-nozzle printer a same-filament 0.6mm K-profile was never retrieved and
the picker showed only the 0.4mm entry ("1 match"). (The AMS-Slot config dialog
was already fixed in #1899; these two pickers were not.)
Add installedNozzleDiameters(status) and a shared fetchPrinterCalibrations()
that queries every reported nozzle diameter and merges the results, falling
back to 0.4 when the printer hasn't reported nozzle hardware. Each profile row
now shows a nozzle-diameter badge so identically-named profiles are distinct.
In the Print dialog's Filament Mapping, each required filament shows its
name and the grams the job needs, e.g. "Bambu PLA Basic (281.2g)". Name and
grams shared one fixed-width column with truncate on the whole string, so a
long name pushed the "(...g)" off the end and clipped it -- partially on a
wide screen, entirely in mobile portrait. The gram usage is the number that
matters (does the spool have enough left?), so it shouldn't be the part that
gets dropped.
Pin the gram usage (shrink-0, whitespace-nowrap) and let only the name
truncate, with the full name on hover. Applied to both the Specific-Printer
(FilamentMapping) and Any-model (PrinterSelector) panels. Layout only.
The File Manager 3D Preview dialog (ModelViewerModal) rendered plate
thumbnails with the raw thumbnail_url. The plate-thumbnail endpoints are
gated behind a camera stream token passed as ?token= (an <img> can't send
an Authorization header), so with auth enabled the browser fetched without
a token and got 401 "Valid camera stream token required" — broken image
icons for every plate. The Slice dialog's picker (PlatePickerModal) and the
Print modal's PlateSelector already append the token via withStreamToken(),
which is why the same file's thumbnails showed there.
Wrap the thumbnail src in withStreamToken(), matching the other two call
sites. The token is synced app-wide and withStreamToken() is a no-op when
auth is off, so non-auth setups are unchanged.
Follow-up to 0f203ce: force color match now picks the right AMS slot, not
just the right printer. The slot mapper cleared tray_info_idx when applying
an override, so on a printer holding two same-colour PLA spools of different
variants (Basic GFA00 / Matte GFA01 / Silk GFA06) it could map to the wrong
one. It now keeps the variant for force_color_match overrides (both the 3MF
and no-3MF fallback paths) so the matcher pins the matching tray, and falls
back to type+colour when that variant isn't loaded. A manual filament swap
(a preference override) still clears the idx so it matches the swapped-in
spool rather than the old one.
The printer-card queue-compatibility hint applies the same variant rule.
Tapping Configure on an AMS slot left the slot popup standing on top of
the filament type/colour dialog it had just opened, so both layers were
on screen at once.
The popup is portaled at z-[60] so it can escape the stacking contexts
sibling printer cards create on the dashboard (#1336), which also puts
it above ConfigureAmsSlotModal and LinkSpoolModal at z-50. Nothing
dismissed it: it is hidden only by the pointer leaving it, and a touch
device never sends that after the tap that opened it. On desktop the
next mouse movement cleared it, which is why this is a tablet report.
FilamentHoverCard and EmptySlotHoverCard now dismiss themselves before
running any action that opens a dialog or navigates away - Configure,
Assign Spool, Unassign Spool, and both Open in Inventory links. The
dismissal clears the pending timer as well, so a queued open cannot
resurrect the card over the dialog.
Actions that report progress inside the popup are unchanged: RFID
re-read, Load and Unload render their spinner there, and Copy UUID its
confirmation tick.
Pairs the top-down plate preview with the slicer's per-object pick mask
(Metadata/pick_N.png), whose pixel colours encode the same identify_id the
firmware's skip command takes, so a click resolves to a real object rather
than an inferred bounding box. Several objects can be selected before one
confirmation; selected and already-skipped items are highlighted on the
plate; the checklist stays available when no mask exists.
view=pick serves only the active plate's mask and 404s otherwise, unlike
every other view. A render returned in a mask's place would be decoded as
object IDs — dark pixels yield small integers that collide with real ones —
and a click would then skip an arbitrary object, mid-print, irreversibly.
The 404 is what tells the UI to fall back to the checklist.
Click mapping goes through the contained rect, since the canvas paints at
mask resolution under object-contain; clicks on a letterbox bar are rejected
rather than clamped onto whichever object touches the border. Confirming
names the object when one is selected and counts them when several are,
which is what plates of identically-named clones need.
No printer-control command path was added or changed; the layer, permission
and existing skip-command guards are untouched.
An end-of-print auto-off on a plug that powers a filter fan marked the linked
printer offline and forced its state to "unknown". The mark was unrecoverable:
connected heals on the next MQTT message but state does not (only frames
carrying gcode_state rewrite it, and steady-state push_status frames are
partial), so the printer stayed "unknown" until a manual Force Refresh and the
queue never dispatched to it again.
The offline mark is now an explicit presumption: mark_power_off records the
state it overwrites and _on_message undoes it as soon as the printer sends
another report on its own topic, since inbound traffic proves the power was
never cut. A reconnect discards the saved state, so a genuine power cut is
unaffected. Each plug also gains a controls_printer_power flag (default true,
backfilled) that gates all five power-off paths, and the queue's power-on step
now picks the flagged plug instead of whichever linked plug came first.
Bed levelling, flow calibration, and nozzle-offset calibration were on/off
only, so the sole way to run bed levelling was to force a full level before
every print. Bambu Studio has always offered a third "Auto" state that lets
the printer skip the calibration when it was done recently -- the state most
users actually want. Make these three options tri-state (off/on/auto),
defaulting to auto, and leave vibration/layer-inspect/timelapse as on/off
(Bambu Studio exposes no auto for those).
Wire encoding follows Bambu Studio's source exactly: each option sends a JSON
bool (true only for "on") plus a companion int -- off=0, on=1, auto=2. The
bool fields stay booleans (the #1478 H2S regression); only the companion int
widened from {0,1} to {0,1,2}. #1721's observation that stage 8/39 stays
queued when sending 2 is the auto contract (queued, skipped at runtime if
recent), not a broken "off".
- schemas: TriState = Literal[off/on/auto] with a BeforeValidator coercing
legacy bool / 0-1 / true-false so old clients and un-migrated rows validate
- model + migration: boolean columns -> String; SQLite via column affinity +
data backfill, PostgreSQL via ALTER COLUMN TYPE guarded on information_schema
(verified on both dialects); settings rows normalised true/false -> on/off
- MQTT: start_print takes the tri-state strings and emits the paired bool+int
- Virtual Printer: reconstructs the slicer's auto/on/off from the int companion
(auto_bed_leveling / extrude_cali_flag) in both capture paths
- frontend: CalibrationMode type; off/auto/on segmented controls in the print
dialog, queue bulk-edit, and Settings -> Workflow; calibrationMode_* strings
in all 11 locales
Focusing any text field on a SpoolBuddy screen (inventory Search, or the
Search / Color Name / Brand fields on write-tag New Spool) blanked the UI
with React error #130 ("Element type is invalid ... but got: object"). It hit
both internal and Spoolman inventories, so it was not data-specific.
The SpoolBuddy shell mounts VirtualKeyboard, an on-screen keyboard that pops up
on focusin for any input -- so every field on every SpoolBuddy page tripped it,
while the main app (no on-screen keyboard) was fine. VirtualKeyboard imports the
default export of react-simple-keyboard, a CommonJS package; under the current
bundler's CJS->ESM interop that default resolves to the module namespace object
({ KeyboardReact, default }) rather than the component, so <Keyboard> renders an
object as an element type and React throws. vitest's interop returns the real
component, so it only manifested in the browser build -- a runtime, not a type,
problem.
Add a small resolveInteropDefault helper that unwraps such an interop-wrapped
default: it returns the value as-is when already a usable element type
(function/class, tag string, or a $$typeof-marked forwardRef/memo/lazy) and
otherwise falls through to .default and named exports. VirtualKeyboard resolves
the real component through it.
Server-side slicing always applied the picked printer/process/filament
triplet via --load-settings, which overrides the designer's embedded
project_settings.config — so a MakerWorld model set up for 5 walls came
out at the picked profile's default 2. That override is correct for
re-slicing a design onto your own printer/AMS, but there was no way to
slice a file the way its author configured it.
SliceModal now offers a "Use the file's built-in settings" checkbox when
the source 3MF carries embedded settings AND the picked printer matches
the design's target model. It routes to the existing embedded-settings
slice path (previously only a crash fallback), so walls/infill/filament
come from the file. Ticking it locks all four preset dropdowns — printer
included, since it's unused on this path and changing it would drop the
match and hide the toggle. The printer-match gate stops embedded settings
being honoured across models (wrong bed); there is no cross-printer
re-targeting on this path.
- schema: use_embedded_settings on SliceRequest
- route: embedded_mode branch; crash-fallback guarded against re-running
- frontend: gated checkbox locking all four dropdowns, resets on mismatch
- 2 i18n keys across all 11 locales
- tests: backend (flag skips triplet / ignored for STL) + frontend
(toggle offered on match, locks dropdowns + sends flag / hidden on mismatch)
The firmware's runout HMS text says "insert into the same AMS slot", which is
wrong under AMS Filament Backup: the firmware won't re-accept the depleted slot
and advances to the next compatible one. Bambuddy parsed print.ams.tray_now only
and dropped tray_tar/tray_pre, so the expected slot never reached the UI.
Capture tray_tar/tray_pre on PrinterState and, while paused, resolve them to
global tray IDs (expected_tray/previous_tray) on both the REST and WebSocket
status payloads via a shared resolver: single-AMS passthrough, multi-AMS
snow-mapping resolution, AMS-HT/external passthrough, and an honest null when the
slot can't be placed. The AMS graphic highlights the expected slot (amber) and
the ran-out slot (red); the HMS modal re-describes runout codes to name both,
falling back to "check the printer" when unresolved. Runout copy translated in
all 11 locales.
Reporter @Jostxxl confirmed tray_pre=1/tray_tar=2 during the pause (ran out in
Slot 2, printer expected Slot 3).
A P1S queue row with use_ams=true but ams_mapping=[-1] was silently
printed with no AMS, starting against the empty external feed and pausing
with a runout. Two faults combined:
- start_print treated -1 (unresolved) the same as >=254 (explicit
external) when deciding to force use_ams=False. Only genuine external
now downgrades; -1 never does.
- The scheduler trusted a stored [-1] as "already resolved" and passed it
through. It now recomputes from live AMS trays whenever the stored
mapping is entirely unresolved, and clears it if nothing matches rather
than sending a doomed command.
Frontend: the Print dialog no longer serializes an all-[-1] mapping while
the printer status is still loading (the hook returns no mapping), and
submit waits for AMS status with a "Waiting for AMS status" notice.
Tests: new backend + frontend regression coverage; corrected one existing
test that pinned the old [-1] -> use_ams=False behavior.
Pushover rejects priority-2 (Emergency) messages unless they carry retry
and expire. _send_pushover never sent them, so setting priority 2 always
failed with Pushover's "retry and expire are required" error. Now at
priority 2 we send retry/expire (default 60s/3600s, clamped to Pushover's
30-10800s range), surfaced as two provider fields shown only when priority
is 2. Added PushoverConfig schema fields, i18n labels across all locales,
and unit tests.
OrcaSlicer shipped a first-class external-app pairing API (OAuth 2.0 Device
Authorization Grant), so the Supabase-PKCE copy-paste flow is replaced end to
end. Connecting is now: click Connect, approve a short code on the Orca Cloud
settings page, done — no redirect, no callback paste, no client secret, works
from a LAN IP / localhost / behind a proxy.
Backend: services/orca_cloud.py rewritten to device-code request + poll (the
four RFC outcomes) + refresh_token grant + introspection + external sync pull;
routes expose /device/start and /device/poll (device_code kept server-side in
the reused orca_cloud_pending_* columns, no migration). Requests sync:read
(read-only feature). Prod endpoint by default, ORCA_CLOUD_API_BASE overrides
to staging. Wired the shared httpx client (fixes a per-request socket leak).
Frontend: device-code connect UI + api client methods; all 11 locales updated.
A queue item's "Any <model>" button labeled itself from the file's slice
metadata while the scheduler used the row's target_model, so an X1C-sliced
item targeting H2D showed "Any X1C" above "assign to first idle H2D". The
mismatch itself was created silently: sliced-for metadata loads async, and
switching to model mode before it arrived pre-selected the alphabetically
first model (H2D on a mixed farm), after which the model dropdown hid
itself. Nothing validated compatibility, so the scheduler would hand X1C
G-code to an H2D.
Frontend: never default the target silently, keep the dropdown visible in
model mode (incompatible models disabled), label from the actual target,
warn on mismatch, block submit when incompatible.
Backend: new GCODE_COMPAT_FAMILIES table (X1/X1C/X1E/P1P/P1S interchange;
everything else exact-match; missing metadata never blocks). Queue create
and update reject incompatible targets with 400; the scheduler holds back
pre-existing mismatched rows with an actionable waiting_reason instead of
dispatching them.
queueing plates we cannot map (#2552)
The override panel disappeared for a multi-plate selection in Any [model]
mode, but only once the dialog had been opened before -- which the reporter
saw as "after the file was queued or printed". The filament requirements are
keyed on the selected plate, which is null as soon as two plates are ticked.
On a cold cache the modal cannot yet tell the file is multi-plate and fetches
the whole file's requirements for one render; the panel rendered from that
union. On a warm cache it knows from the first render, the whole-file fetch
never runs, and the panel had nothing to render. Visibility was decided by a
cache race, and the "working" case listed filaments from plates the user had
not selected.
Model mode now renders one panel per selected plate from that plate's own
requirements, and each queued plate carries only the overrides for the slots
it prints, so a colour forced on one plate no longer blocks another.
Reviewing the per-plate machinery turned up four more holes, all closed here:
a manual tray pick survived a change of printer, and a global tray id names a
different spool on a different machine; a plate whose filaments could not be
read was indistinguishable from one needing none and was queued with neither
mapping nor forced colours, so Print now waits for every selected plate to
answer and names the one it cannot read; the insufficient-filament check still
weighed the whole file against a mapping the plates no longer use, and now
follows what each plate dispatches, summing demand per tray; and the
per-printer tray editor no longer appears for a multi-plate fan-out, where its
choices were collected and then discarded.
Selecting several plates hid the filament mapping panel but did not stop the
modal sending a mapping. With no single plate selected it fell back to the
whole file's filament list -- the union of every plate -- and matched against
that. Tray assignment is stateful, so where plate 1 prints red on slot 1 and
plate 2 prints red on slot 2, slot 1 claimed the only red spool and slot 2 fell
through to a type-only match on black. That one mapping went out with every
plate, and the scheduler uses a stored mapping verbatim, so plate 2 printed in
the wrong colour -- decided by a panel the user never saw.
Fetch each selected plate's requirements and map them separately: one panel per
plate, named after it, with its own tray overrides, and each queue item carries
its own plate's mapping. A fan-out across several printers would be a panel per
plate per printer, so those items carry no mapping and the scheduler maps each
plate against the printer it picks. Model mode is unchanged -- no printer means
no trays to map onto.
The tray matcher existed twice and this needed a third caller, so extract it
once and have both existing paths delegate; its 62 tests pass unchanged.
The bug only reproduces with a realistic query cache -- the shared test harness
sets gcTime: 0, which evicts the union and makes the modal look innocent -- so
the new modal tests bring their own client.
Nightly backups to a mounted NAS share ran from May and then stopped, failing
with [Errno 30] Read-only file system. The reporter checked folder permissions
-- correctly: the mount is gid=backup,dir_mode=0775, the service user is in that
group, and his own shell writes to the share fine.
Errno 30 is EROFS. A permission problem is errno 13. EROFS means the filesystem
refused the write, and it refused because we told it to: our systemd unit ships
ProtectSystem=strict, which mounts everything read-only inside the service's
mount namespace and carves back out only ReadWritePaths=<install> <data> <logs>.
A NAS share is not one of those three. Reads are unaffected -- which is why the
UI happily listed his existing backups from the share while being unable to
write a new one -- and his shell is outside the namespace entirely, so every
check he could think to run said the directory was fine.
Both installers write the unit file wholesale, so a ReadWritePaths line added by
hand disappeared on the next install, taking the backups with it. They now back
the old unit up (.bak-<timestamp>) and carry the operator's extra writable paths
forward, reporting which ones they kept. The unit template documents the
carve-out.
The output directory is probed with a real write when it is saved and when the
backup card loads, so an unwritable path is caught there rather than at 03:00
for a week. On failure the card names the cause and hands over the fix with the
operator's path already in it (systemctl edit bambuddy -> ReadWritePaths=...),
and a failed run reports the same diagnosis rather than the raw OSError. EROFS
outside systemd, permission-denied, out-of-space, not-a-directory and missing are
told apart, in all 11 locales.
Docker: a backup path that is not bind-mounted is writable -- the write lands in
the container's ephemeral layer and is lost on the next compose up. The probe
compares the directory's device against the container root and warns, with the
compose snippet that mounts it properly.
A Shelly reports one energy figure — aenergy.total, a lifetime counter in Wh
that never resets. Bambuddy had a single REST energy field and filed whatever
it found under "today", so the value never reset at midnight, and Yesterday
and Total stayed at zero: get_energy() simply never set those keys.
With `total` unpopulated, the hourly snapshot recorder skipped the plug, so
the Statistics page's energy figure was zero as well, not just the Settings
card.
Split the REST energy config in two: rest_energy_path still means "used
today", rest_energy_total_path means "lifetime counter". A Shelly has only
the latter; a Tasmota behind a REST bridge has both; sharing a URL costs one
fetch, not two.
Then derive Today and Yesterday from that counter using the snapshots we were
already taking: today = counter now - counter at the last local midnight;
yesterday = the gap between the two previous midnights. Local midnight, not
UTC — a UTC boundary rolls Today over at 02:00 in Berlin. The snapshot loop
now ticks on the local hour so a reading lands on the boundary instead of up
to an hour early. A counter that goes backwards (factory reset) reports
nothing rather than a negative.
Collateral, found while verifying on both engines: the smart-plug DateTime
columns are naive UTC but the code wrote aware datetimes into them. SQLite
drops the offset; asyncpg raises DataError. So on Postgres every snapshot
capture raised inside the loop's except, and every status poll raised on
last_checked — the whole subsystem was dead on the database we recommend for
multi-printer installs. All plug timestamps are naive UTC now.
Existing REST users with a cumulative path in the today field must move it to
the new lifetime field; the form and wiki now name which counter each wants.
Cam Wall had no URL — the only way in was the toggle on the Printers page,
so it could not be bookmarked, linked, or shown on a wall-mounted screen.
Add a standalone /camwall route. Signed in, it is the wall as it was. For a
TV or Pi with no login, it authenticates with a long-lived token in the URL.
A kiosk needs the printer list and per-printer status, both of which sit
behind PRINTERS_READ. Rather than widen camera_stream to cover GET /printers
— whose response carries serial_number and ip_address, which have no business
on a screen in a shared room — add a read-only feed at
GET /api/v1/camwall/printers that serves only what a tile draws, and gate it
on a new camwall token scope. The print filename is not served at all: a token
wall renders the compact overlay, so the part on the bed is never named.
The scope is separate rather than a widening: camera_stream tokens are already
in the wild, minted to hand out video, and must not gain the ability to
enumerate a fleet by name. camera_stream is refused by the feed; camwall
passes the stream gate so its own tiles fill.
Kiosk walls drop the settings popover and click-through entirely (not merely
hidden — a passive screen must carry no focusable control it cannot act on),
cap the overlay at compact, and poll rather than open a WebSocket. maxLive,
interval and status can be set from the URL, clamped to the popover's ranges.
A spool with no readable RFID was reported by the standard AMS with an empty
tray_type and state=9 — structurally identical to a truly-empty slot at the
tray level — so the AMS card rendered it "Empty" while Bambu Studio correctly
showed "?". The authoritative "a spool is physically here" signal is firmware's
AMS-level tray_exist_bits bitmask (what Studio uses), but Bambuddy inferred
emptiness from the per-tray state/tray_type. Confirmed from the reporter's
bundle: tray_exist_bits=f (all four slots present) with tray_is_bbl_bits=5
(only slots 0,2 Bambu) — the present-but-non-Bambu slots were the ones shown
Empty. Supersedes closed#1838.
apply_tray_exist_bits() already parses the bitmask to clear stale fields on
absent slots; it now also annotates each slot with an authoritative `exists`
bool, gated behind a new annotate_exists flag so only the printer-card path
sets it. The VP bridge leaves it off, so the `exists` key never reaches the
slicer wire format. `exists` flows through the AMSTray schema/serialization to
the frontend, where getEmptySlotKind() uses it: exists===true + no tray_type
-> "?" (present, unconfigured), exists===false -> "Empty", exists absent ->
the previous state=9/10 heuristic (AMS-HT and missing-bitmask paths unchanged).
H2D/X1C already reported present-unknown slots with a non-9 state and took the
"?" path; with the fix they reach it via `exists` and are unaffected.
P1-series printers have a MicroSD slot but no reachable control to enable
"Store sent files on external storage": current P1 firmware (through
01.10.00.00) never publishes support_save_remote_print_file_to_storage, so
the Bambu Studio toggle never renders, and the P1S has no screen — leaving
store_to_sdcard stuck False with no way for the user to change it. The
external_storage check reported a permanently-unresolvable fail.
Add NO_REMOTE_STORAGE_TOGGLE_MODELS (P1S, P1P) + has_remote_storage_toggle(),
kept distinct from the no-slot NO_EXTERNAL_STORAGE_MODELS. When a model has a
slot but no reachable toggle and the option is off, the check now emits skip
with params reason=unsupported_model rather than fail, and overall no longer
escalates. A P1S reporting the option on still passes. Model-scoped and
default-open, so X1/P2S/H2 (where the fail is actionable) are unaffected; if
a future firmware surfaces the capability, drop the model and it reactivates.
The frontend DiagnosticChecklist renders a reason-specific message variant
(external_storage.skip_unsupported_model) so P1 users see an accurate
explanation instead of the generic "needs a live MQTT connection" skip text.
The fix propagates to the support-bundle diagnostic snapshot automatically.
The README panel rendered full-width above the file grid, pushing model
files below the fold with no page scroll to get past it. On lg+ it now
docks as a fixed-width right-hand column beside the list (own full-height
scroll); on mobile it stacks on top and the page scrolls. Added a collapse
toggle (thin strip / slim bar + one-click reopen) with the choice persisted
to localStorage. New i18n keys readme.show/hide/label across 11 locales.
The 40x30 mm box label rendered its QR too densely for low-res thermal
printers — the modules bled together and wouldn't scan. Two causes: the QR
was 20% of inner width (~7.5 mm on the narrowest template, half of the
others) and used ERROR_CORRECT_M. Fix adaptively so all templates benefit:
give the roomy-layout QR a 12 mm minimum size (box_40x30 -> 12 mm, ~3.5
dots/module at 203 dpi) and switch label QRs to ERROR_CORRECT_L (same
payload, chunkier modules; a label needs no M-level recovery). Keep the
quiet-zone border at 2 — the size+L gains suffice without risking scans.
Also add a Monochrome (black & white printer) option to the label dialog:
drops the colour swatch (a useless grey block on B&W) and widens the text;
the hex-code line still carries the colour. Threaded through the renderer,
route, API client, and modal, with translations in all 11 locales.
The app was built dark-first, so hundreds of hardcoded Tailwind semantic
text/icon utilities at light shades (text-amber-400, text-blue-300, ...) had
no dark: variant. With darkMode:'class' they applied in light theme too,
producing washed-out text on pale tints and white cards — including the three
reported spots (AMS Drying banner, Archives no-3MF warning, debug-logging
banner). Give each a theme-aware pair: a darker readable shade in light theme
with the original pinned to dark:, so dark theme is unchanged. ~100 files.
The bambu-* CSS-variable palette (self-correcting) and the dark-only SpoolBuddy
kiosk are left untouched. Plain text-white is already theme-aware via the
existing index.css .text-white override, so it needed no changes.
The sidebar-ordering refactor in #1673 accidentally dropped the
`notifications` entry from `defaultNavItems` and its
`notifications:user_email` permission mapping, but kept the advanced-auth
visibility gate that references that id. With no nav entry the id never
enters the render set, so the /notifications page (route, page, and API
all intact) became reachable only by typing the URL — users could no
longer opt in/out of their own print email notifications from the menu.
Restore both the defaultNavItems entry and the permission gate, matching
the permission the user-email-preferences API actually requires
(notifications:user_email, held by both default groups). Add comments so
the entry isn't dropped again in a future sidebar refactor.
Editing a queue item that was created with "Any of model X" left the
printer selection area completely blank — the assignmentMode was
initialised to 'model' from queueItem.target_model, but the three
model-mode props (onAssignmentModeChange, onTargetModelChange,
onTargetLocationChange) were gated behind !isEditing. That flipped
modelAssignmentAvailable to false in PrinterSelector and hid the mode
toggle, the model dropdown, AND the location filter; combined with the
assignmentMode === 'printer' gate on the printer list, the whole
selector rendered empty.
Users hit this whenever they queued something to "Any of model X" and
then wanted to change the target model / location — the only workaround
was delete + re-queue.
Fix: drop the !isEditing gate on all three PrinterSelector props. The
submit path already handles both flavours (target_model+target_location
with printer_id=null vs. printer_id with the target fields nulled), so
un-gating the UI just surfaces the machinery that was already there.
Edit is still only offered on pending items, so the mode-flip can't race
an in-flight dispatch.
PrintModal carried a useEffect that reset scheduleOptions.gcodeInjection
to false whenever mode === 'create' AND effectiveQuantity <= 1. The
comment claimed the checkbox only renders for quantity > 1, but the
actual render gate in ScheduleOptions is just hasGcodeSnippets — no
quantity check. So with snippets configured + quantity = 1 (the OP
scenario): user clicks the checkbox, React updates state to true,
the parent's useEffect immediately sees effectiveQuantity <= 1 and
resets to false, and the checkbox appears un-clickable. Edit-queue-
item mode worked because mode !== 'create' short-circuited the reset.
Drop the effectiveQuantity <= 1 clause from the reset. Keep the
!settings?.gcode_snippets half as the legitimate cleanup for the
"admin removes all snippets while modal is open" case. The scheduler
reads item.gcode_injection per queue item regardless of batch size,
so single prints can inject too.
New scheduler stage that heats the bed (and the chamber, on supported
printers) and holds at temperature before each queued print starts —
the heat-soak engineering filaments need for adhesion and warp
control. Bambuddy waits between FTP upload and start_print, so the
soak runs while the printer is otherwise idle. M191 is silently
ignored by Bambu firmware, so doing this at the orchestration layer
is the only place it works.
Resolution order at dispatch:
1. PrintQueueItem.preheat_override ∈ {inherit, on, off}.
'off' skips entirely; 'inherit' falls back to the global
preheat_enabled toggle; 'on' forces the stage even when the
global is off.
2. chamber_target = item.preheat_chamber_target_override
?? max(filament_map[normalize(t.tray_type)] for loaded slots)
?? 0.
Mixed PA+PLA picks PA's 50 (max-across-slots — PA's chamber
requirement is binding, PLA doesn't suffer being warm). PLA-only
derives 0 and skips the chamber phase automatically.
3. Three hardware tiers for chamber heat:
- Active chamber heater (H2C/H2D/H2D Pro/H2S/X2D/X1E) → M141 +
chamber-sensor wait
- Chamber sensor only (X1C/P2S) → no M141, passive bed-radiation
wait with hard max-wait cap
- No chamber sensor (P1S/P1P/A1/A1 Mini) → bed + soak timer only
4. Airduct flap (H2C/H2D/H2D Pro/H2S/X2D/P2S) auto-switches to
match the chamber target — heating mode for engineering
filaments, cooling mode for PLA. Bambu firmware does NOT
auto-switch the flap with M141, so without this an ABS print
on a previously-cooling flap fights the open exhaust, and a
PLA print on a previously-hot flap recirculates ABS heat.
Idempotent: only fires set_airduct_mode when current ≠ desired.
Settings → Workflow → Queue & Dispatch → Preheat & Heat Soak card:
master enable toggle (default off — disabled installs see no change),
per-filament chamber-target editor (replaces a single global int that
shipped in the first cut and couldn't serve PA + PLA in the same
config), preheat_max_wait_seconds, preheat_soak_seconds. The Print
Options panel in PrintModal gets a Preheat sub-section with the
tri-state Inherit/On/Off control and an optional chamber-target
override input.
DB migration: PrintQueueItem gains preheat_override VARCHAR(10)
DEFAULT 'inherit' and preheat_chamber_target_override INTEGER NULL.
Idempotent via _safe_execute. Existing rows behave exactly as before
the migration.
Best-effort throughout: printer drops, refused M141 or set_airduct,
missing bed temp, lost MQTT state mid-wait all log and return cleanly.
Normal upload + start path runs after this returns regardless.
The HMS error modal had three compounding bugs that surfaced when a
user forced a wrong-plate HMS (0500_8051) and tried to dispatch the
per-fault actions.
(1) IGNORE_RESUME did not ignore. Bambuddy redirected the action on
state=PAUSE to a plain `resume` command, citing a #1830 verdict that
BambuStudio's "err-bearing shape" was firmware-silently-rejected.
BambuStudio source disagrees: DeviceErrorDialog.cpp:600 dispatches
IGNORE_RESUME via command_hms_ignore, whose wire shape is
{command:"ignore", err:"<decimal>", param:"reserve", job_id:...}.
That's a distinct command from `resume` — the firmware suppresses
the next re-check AND auto-resumes in one operation. Plain resume
means "re-check normally", which is exactly why the wrong-plate
detection re-fired 1-2 s after the user clicked Ignore. The #1830
"err-bearing shape rejected" test almost certainly sent the err as
a hex shortcode; BambuStudio passes std::to_string(int m_error_code)
i.e. the DECIMAL form, which is what the firmware matches against.
(2) Action buttons read as inert badges. The button className used
`hover:${buttonHoverColor}` — a template-literal interpolation
Tailwind's JIT scanner can't see as a literal string, so the
per-severity hover utility never reached the compiled CSS. Same
bg/text color as the severity badge above and no border made it
read as another label. No disabled state and no spinner during the
2.5 s ack wait left clicks sitting silently inert.
(3) Ack-detection 502'd on legitimate ack. The route compared
(gcode_state, hms_errors-len) before vs after publish; wrong-plate
re-pause round-tripped both fields to their pre-publish values
inside the 2.5 s window → false 502 even though the firmware fully
ack'd. PROBLEM_SOLVED_RESUME working but IGNORE_RESUME 502'ing on
the same fault was the same race resolving differently.
Fixes:
bambu_mqtt.py — new hms_ignore_command() publishes the BambuStudio
shape; existing hms_ignore(persistent) renamed to hms_idle_ignore
(unchanged shape, used by NO_REMINDER_NEXT_TIME per
DeviceErrorDialog.cpp:588). Dispatch routes IGNORE_RESUME,
IGNORE_NO_REMINDER_NEXT_TIME, and DONT_REMIND_NEXT_TIME to
hms_ignore_command (BambuStudio routes all three to the same
command_hms_ignore — the "don't remind" half is the firmware's
job). NO_REMINDER_NEXT_TIME stays on hms_idle_ignore type=0. Hex →
decimal err conversion at the helper layer with a defensive
fallback. job_id=None → empty string (matches BambuStudio's
std::string default).
HMSErrorModal.tsx — getSeverityInfo loses the dead buttonHoverColor
field. Action button uses static
`bg-white/10 hover:bg-white/20 active:bg-white/30 text-white
border border-white/20`, wires
`disabled={!hasPermission||mutation.isPending}`, and renders
`<Loader2/>` only on the button whose (action,print_error) matches
mutation.variables.
printers.py — ack-detection probes `client._last_message_time`
(bumped on every MQTT push regardless of payload) rather than
diffing state fields. The pushall that follows every command
guarantees a fresh push lands inside the 2.5 s window on any
healthy printer; only firmware-silent-drop leaves the timestamp
untouched, which is the 502 path #1830 wanted.
Two compounding bugs let an H2C-bound filament land in slot 1 of an A1
slice silently. (1) `_slicer_rejection_message` discarded the actual CLI
diagnostic - `filament preset Generic PLA @BBL H2C (slot 1) is not
compatible with printer Bambu Lab A1 0.4 nozzle.` - when the sidecar's
headline error_string was Bambu Studio's catch-all
`The input preset file is invalid and can not be parsed.` placeholder.
The real reason was in the stdout `[error] run NNNN:` line, trimmed off
before reaching the SliceJob's error_detail. (2) `pickFilamentForSlot`
used a soft `-100` mismatch penalty rather than a hard skip, leaving
the "never auto-fill an incompatible preset while a compatible one
exists" contract implicit. The unused-slot substitution in
`substitute_unused_plate_filaments` then propagated whatever slot 1
held across every unused slot - one bad pick poisoned the array.
(1) Mine `[error] <msg>` (with or without `run NNNN:`) from the full
pre-trim response; substitute the placeholder, keep meaningful
headlines. (2) Partition candidates into compatible/unknown vs
mismatch; prefer compatible whenever the bucket is non-empty, fall
back to mismatch only on graceful-degrade. Picker helpers moved out
of `SliceModal.tsx` into `utils/slicePresetPicker.ts` so the modal
file stays component-only (react-refresh lint).
filterKnownHMSErrors and the modal-local copy gated visibility on
ERROR_DESCRIPTIONS membership. H2C 0500_809C carries IGNORE_RESUME /
PROBLEM_SOLVED_RESUME but is missing from the bundled 853-entry catalog,
so the entire error — pip, count, panel, action buttons — never rendered
even though backend captured + dispatched it correctly.
The gate isn't dead code: PrintersPageBucketing pins the post-cancel
0C00_001B junk-echo regression to it. Widen the predicate to keep
(cataloged) OR (actions.length > 0) so noise is still filtered out
while user-actionable faults always surface.
Replace the modal's inline filter with the shared helper so badge
counts and modal contents agree by construction. Fall back to
hmsErrors.unknownCode ("Unknown HMS code — see the Bambu Lab wiki
for details.") when the catalog has no entry. New key translated in
all 11 locales.
New bucketing test pins PAUSE + uncataloged-with-actions = error;
existing FAILED + uncataloged-without-actions = finished stays green.
Administrators system group sync
- Fresh installs already bootstrap with ALL_PERMISSIONS, so they always have
every permission. Upgrades previously only got what one-off backfill blocks
in seed_default_groups() explicitly listed (library:purge, archives:purge,
the OWN/ALL read-flag block, orca_cloud:auth, pipelines:*). Any Permission
enum member added without a matching block silently stayed missing on
existing admin rows. The most recent gap was printer_sensor_history:read
(Sensor History charts returned 403 for upgraded admins).
- seed_default_groups() now syncs Administrators to ALL_PERMISSIONS on every
startup: append every Permission value that isn't already on the row.
Additive only -- hand-added custom permissions are preserved.
- The pure-admin one-off backfills (library:purge / archives:purge block,
the OWN/ALL + orca_cloud:auth + legacy-read-flag block, the Administrators
branch of the pipeline backfill) are retired since the sync subsumes
them. Non-admin backfills (Operators / Viewers OWN-tier reads, Operators
orca_cloud:auth, pipelines for non-admin groups, makerworld:*, clear_plate
cross-group adders) are untouched.
- Tests: test_administrators_printer_sensor_history_read_backfilled
(regression for the reported gap),
test_administrators_sync_covers_every_current_permission (generic
invariant -- any future new permission lands on admin without needing
a one-off test), test_administrators_sync_is_additive_only (custom
permissions preserved). 12/12 backfill-migration + 102/102 broader
permission tests green; ruff clean.
Pipelines runs dashboard
- PipelineRunsPage.tsx: the Pipeline / Status / Target filter row's three
native <select> elements are replaced with a bambu-themed FilterDropdown
(button trigger, floating menu, optgroup-style headers for the Target
picker, hover + selected states with a check mark, closes on outside
click and Escape). Same value/onChange contract -- visual only.
- SlicerPipelinesPanel.tsx: wrap list?.pipelines ?? [] in useMemo so the
reference is stable when the data is stable. Fixes the
react-hooks/exhaustive-deps warning where the inline fallback returned
a fresh empty array every render, invalidating both downstream useMemo
caches (target-options + filtered-pipelines list).
PR A/B turned the slice modal's preset bundle into a one-click dispatch
with a pinned target printer. PR C closes the original issue: operators
type in a number of copies, Bambuddy slices once and distributes prints
across a fleet per the pipeline's chosen fanout strategy. A new dashboard
surfaces every run with filters, expandable per-copy status, cancel,
and retry-failed-copies. WS pushes keep everything live.
Backend
- copies field on POST /run, capped by new pipeline_max_copies setting
(default 50, hard cap 1000). PipelineRun.parent_run_id chains retries.
- SlicerPipelineUpdate accepts target_kind (specific_printer /
printer_class), target_model_class, fanout_strategy.
- Eligibility matcher branches: class-targeting enumerates matching
Printer rows, runs per-printer checks via a status_lookup closure,
returns printer_reports[]. New issue kinds: no_class_matches,
class_not_set.
- _pick_assignments distributes copies per strategy:
- max_parallel: target_model set, printer_id None — scheduler picks
- round_robin: copy i → eligible[i % N], fixed printer_id
- fill_one_first: all copies pinned to eligible[0]
All three reuse the slice-once path through slice_dispatch.enqueue.
- New routes:
- GET /pipeline-runs (paginated, filterable by pipeline + status)
- POST /pipeline-runs/{id}/retry-failed (creates child run with
copies = failed+cancelled count, parent_run_id set)
- Cancel cascades to all N queue entries (only pending/queued)
- _roll_up_run_status computes run-level status from per-job statuses;
introduces partial_failure for "some completed, some failed".
- ws_manager.broadcast_to_user emits pipeline_run_updated on every
state transition with the full materialised response.
Frontend
- Pipeline editor: target_kind radio + class picker (filtered to
installed models) + fanout-strategy radio. Read-only row shows
"X1C · Round robin" for class pipelines.
- RunWithPipelineModal: copies number input bounded by
settings.pipeline_max_copies. Accepts class-targeted pipelines.
- Settings → Workflow → Queue & Dispatch: new "Slicer Pipeline limits"
card with the max-copies input.
- New /pipelines/runs dashboard page (sidebar entry, gated on
pipelines:read). Two-filter dropdown, 25-per-page pagination, per-row
expandable to job list, Cancel + Retry-failed buttons.
- useWebSocket case for pipeline_run_updated invalidates both
pipeline-runs-all and pipeline-runs/{id} query keys.
Two real gaps from the PR B drop:
1. Run-with-pipeline only existed in the file manager. Operators who keep
working files in archives had to copy them to the library to use a
pipeline.
2. Triggering a slice via a pipeline produced a silent multi-second-to-
minute wait. The manual SliceModal flow shows the sticky
"Slicing X - Generating G-code 75%" persistent toast; the pipeline
path went through asyncio.create_task directly and never registered
with SliceJobTracker.
Archive entry point
- POST /slicer-pipelines/{id}/check-eligibility and /run accept
source_archive_id as an alternative to source_library_file_id (XOR,
enforced by Pydantic validator).
- PipelineRun.source_archive_id is a new nullable FK column with the
ALTER TABLE migration in run_migrations (idempotent via _safe_execute,
works on SQLite + Postgres).
- _resolve_source branches: archive path reads source_3mf_path with
fallback to file_path, mirroring routes/archives.py.
- ArchiveCard's context menu picks up a "Run with pipeline" item next to
Slice (only on source archives), gated on useSlicerApi + pipelines:run.
Slice (only on source archives), gated on useSlicerApi + pipelines:run.
- Path-safety: SEC-PATH-OK markers added at both LibraryFile.file_path
and archive.source_3mf_path join sites, citing the upload-time
validators.
Progress toast
- Pipeline orchestration is now the `run` callable of a
slice_dispatch.enqueue call — the same dispatcher SliceModal uses —
instead of a bare asyncio.create_task. The SliceJob lifecycle drives
the existing progress toast end to end with no separate notification
surface for pipeline runs.
- PipelineRun.slice_job_id is set before the 202 returns.
- RunWithPipelineModal calls useSliceJobTracker().trackJob() from
runMutation.onSuccess.
- RunWithPipelineModal source prop is now {kind, id, filename}
mirroring SliceModal.SliceSource; api.checkPipelineEligibility +
api.runPipeline take a discriminated-union source argument.
The SliceModal forces the user to pick four slots every time (printer /
process / filament(s) / bed type). For fleet production that's tedious
and error-prone. Pipelines let an operator save a named bundle and apply
it with one click on the next file.
PR A is bundle-and-management only. PR B adds single-target dispatch,
PR C adds multi-copy batch with capability-matched fanout. Future-PR
columns (target_kind / target_printer_id / target_model_class /
fanout_strategy) ship in this migration so PR B+ is code-only, not a
schema bump.
Backend
- New model SlicerPipeline + slicer_pipelines table; soft-delete via
is_deleted so PR B+ run history can still resolve metadata.
- Pydantic schemas reuse the existing PresetRef shape from
schemas/slicer.py.
- CRUD routes at /api/v1/slicer-pipelines/ — list (newest first by id
DESC), create (201), get-by-id, partial PUT, soft-delete (204).
- Three new permissions: PIPELINES_READ / PIPELINES_WRITE / PIPELINES_RUN.
Administrators + Operators get all three; Viewers get READ.
Backfill in seed_default_groups() so existing installs upgrade
cleanly. All three denied to API keys for now.
Frontend
- Settings → Workflow splits into two horizontal sub-tabs mirroring
the Authentication tab pattern: "Queue & Dispatch" (existing
Workflow content) and "Pipelines" (new). URL deep-link via
?tab=queue&sub=pipelines.
- SlicerPipelinesPanel — list, inline rename, delete, stale-preset
warning when a referenced preset no longer resolves.
- SliceModal gets "Apply pipeline ▾" + "Save as pipeline". Apply
fills all four slot states; the filament list right-pads from
current state so a pipeline with fewer entries than the current
source's slot count keeps the existing tail.
The original #793 fix added the spool note as an HTML title= tooltip
on each picker button in AssignSpoolModal.tsx. title= only surfaces
on hover, which doesn't exist on touch devices — phone users tapping
a card just selected it, the note never appeared. Users who store
their tracking ID in the note field were blind on mobile (raised by
@EmcetPL on the closed issue).
Render the note as a small muted truncated line directly under the
weight on both the internal-inventory branch (line 436-ish) and the
Spoolman branch (line 510-ish): text-[10px] text-bambu-gray/70 mt-1
truncate, kept inside the truthy `&&` guard so empty notes don't add
a blank row. The existing title={spool.note} is preserved on the new
<p> so desktop hover and mobile long-press still surface the full
untruncated text for notes that overflow the truncate.
Mirrored across both inventory branches per the parity rule
(internal and Spoolman pickers stay shape-equal). No backend change,
no new state, no popover, no new touch target.
Three distinct bugs combined into one user-facing failure: clicking
Stop / Problem-solved-and-resume / Ignore-and-resume returned 200 OK
but the printer didn't act, modal stayed up, print stayed paused.
Verified by injecting candidate command shapes on device/<sn>/request
against a live H2D paused on a wrong-plate HMS (print_error=0x05008051).
(1) hms_resume / hms_stop dispatched the "err"-bearing shape that
BambuStudio doesn't actually send; Bambu firmware silently rejects it.
Both now send the plain shape ({"print":{"command":"<x>","param":"",
"sequence_id":"0"}}). PAUSE -> FAILED in 1.7s for stop, PAUSE -> RUNNING
in <2s for resume.
(2) IGNORE_RESUME mapped to idle_ignore, which is BambuStudio's
"dismiss a warning" command and only works for non-pause warnings.
hms_ignore now branches on state.state == "PAUSE": paused -> plain
resume; not-paused -> idle_ignore with the full-length err.
(3) 64-bit hms[]-array faults were truncated to a non-matching err.
short_code in _parse_status discarded 32 of the 64 identifier bits, so
the firmware didn't match it to the active fault. HMSError.full_code
now carries the canonical hex identifier (16 chars for hms[] faults,
8 chars for print_error faults). Catalog lookup tries 16-char first,
falls back to 8-char. HmsActionBody.print_error pattern relaxed to
^[0-9A-Fa-f]{8}([0-9A-Fa-f]{8})?$.
(4) execute_hms_action returned publish-success as success, masking
every silent-rejection bug above as 200 OK. Route now snapshots
(state.state, len(state.hms_errors)) before dispatch, awaits
HMS_ACTION_ACK_WAIT_SECONDS (default 2.5s, module-level so tests
override), and returns 502 with "Printer did not acknowledge HMS
action within 2.5s" if state didn't move.
On dual-nozzle printers (H2C/H2D), the External card stacked a
separate "Ext-L" / "Ext-R" caption below each tray to mark which
extruder it fed. That caption appeared on the External card only,
making the bottom row of the printer card's AMS panel visibly
taller than the row above it.
Fix: the L/R distinction now lives inside the slot's colour circle
in place of the numeric index, and the bottom caption is removed.
FilamentSlotCircle's slotNumber prop is widened to `number | string`
to carry the letter. Single-nozzle externals (one tray, no L/R
distinction) keep the numeric "1".
The Ext-L / Ext-R strings still drive the slot's "location" label
in the filament hover card, so detail context is preserved.
streams when one viewer closes
1) Offline tiles now show OFF (not LIVE)
CameraWall.modeByPrinter assigned 'live' to any visible printer
without considering status.connected, so a disconnected X1C wasted
a live-budget slot AND rendered the red LIVE chip on top of the
WifiOff placeholder. Disconnected printers now map to 'paused' and
don't decrement liveBudget — the existing WifiOff + Off chip
rendering takes over.
2) /camera/stop no longer kills other viewers' streams
The cam-wall tile, EmbeddedCameraViewer, and the /camera/:id popup
all subscribe to the same fan-out broadcaster for a printer.
/camera/stop used to unconditionally shutdown_broadcaster() + kill
every ffmpeg process for the printer, so closing the embedded viewer
while the cam-wall tile of the same printer was live force-killed
the source the tile was pulling from — the tile's <img> errored.
New get_subscriber_count(key) accessor in camera_fanout.py exposes
the broadcaster's subscriber list length. /camera/stop now reads
that first; when >= 1 subscriber is still attached, return
{stopped: 0, skipped: true} and leave the broadcaster + ffmpeg
processes alone. The leaving viewer's HTTP teardown still runs the
natural iter_subscriber.finally -> unsubscribe path, so its slot is
released; the broadcaster keeps serving the other viewers. Single-
viewer close still hits the immediate force-teardown (count is 0).
