Sidebar nav items (Archives, Queue, Stats, Profiles, Maintenance,
Projects, Inventory, Files) were visible to all users regardless of
role permissions — only Settings was gated. Now each item is hidden
when the user lacks the corresponding read permission. Printers
remains always visible as the home page.
Also adds missing inventory:read|create|update|delete to the frontend
Permission type (existed in backend but was absent from the frontend
type definition).
Fix camera button permissions & ffmpeg process leak (#550)
Camera button on printer card was clickable without camera:view
permission. ffmpeg processes (~240MB each) accumulated after closing
camera streams because: (1) stop endpoint called terminate() without
wait()/kill(), (2) HTTP disconnect detection only ran between frames
so was blocked when the generator was stuck on stdout read, and
(3) no mechanism caught processes orphaned by generator abandonment
or app restarts.
- Add camera:view permission check + tooltip to camera button
- Fix stop endpoint: terminate() → wait(2s) → kill() → wait()
- Add background disconnect monitor (polls every 2s, kills ffmpeg
directly on disconnect)
- Add periodic /proc scan (every 60s) that SIGKILLs any ffmpeg
with rtsps://bblp: not in an active stream
- Add noCamera i18n key to all 6 locales
- Fix camera API test mocks for async wait() and pid attribute
The H2C dual nozzle variant reports model code O1C2 via MQTT, but only
O1C was recognized. This caused the camera to use the wrong protocol
(chamber image on port 6000 instead of RTSP on port 322), producing a
reconnect loop. Added O1C2 to all model ID maps across 8 files.
Some firmware versions send MQTT payloads with non-UTF-8 bytes.
UnicodeDecodeError was uncaught, silently dropping the entire message
and leaving printer status as "unknown" with 0°C temps and no AMS.
Fall back to decode(errors="replace") to keep JSON parseable.
The tare and calibrate buttons on the Settings page queued commands
but never executed them due to five broken links:
1. Daemon received tare command but never called scale.tare()
2. No endpoint to persist tare offset back to backend DB
3. Heartbeat never called scale.update_calibration()
4. Heartbeat response with stale values overwrote new tare to zero
5. set-factor used DB tare_offset (stale/zero), producing wrong
calibration factor — empty scale showed ~5000g
Fixed daemon to execute tare, persist result, and propagate
calibration. Calibration step now captures raw ADC at tare time
and sends it with step 2, making factor computation self-contained.
Replaced calibration weight input with compact touch numpad for
the RPi kiosk's 1024x600 touchscreen (no physical keyboard).
The tare and calibrate buttons on the Settings page queued commands
but never executed them due to four broken links:
1. Daemon received tare command via heartbeat but never called
scale.tare() — the ScaleReader was available in shared dict
but unused
2. No API endpoint for the daemon to report the new tare offset
back to the backend DB, so tare results were lost
3. Heartbeat updated config but never called
scale.update_calibration(), so ScaleReader kept initial values
4. The heartbeat response delivering the tare command still had
pre-tare values, immediately overwriting the new offset to zero
Added set-tare endpoint + API client method, and fixed heartbeat
loop to execute tare, persist the result, propagate calibration
changes to the ScaleReader, and skip calibration sync on the
heartbeat cycle that delivers a tare command.
Also replaced the calibration weight input with a touch-friendly
numpad since the RPi kiosk has no physical keyboard.

2. No API endpoint for the daemon to report the new tare offset
back to the backend DB, so tare results were lost
3. Heartbeat updated config but never called

Added set-tare endpoint + API client method, and fixed heartbeat
loop to execute tare, persist the result, and propagate calibration
changes to the ScaleReader instance. Skip calibration sync on the
heartbeat cycle that delivers a tare command, since the response
predates the tare and would overwrite it with stale values.

Frontend: Replace inline SpoolInfoCard/UnknownTagCard with full-screen
TagDetectedModal that auto-opens on NFC tag detection. Known spools show
remaining weight, fill bar, and offer "Assign to AMS" (new sub-modal with
printer selector + AMS slot grid) and "Sync Weight". Unknown tags offer
"Add to Inventory" and "Link to Spool". Modal stays open on tag removal,
won't re-open for dismissed tags, reopens on re-place after removal.
Daemon: Fix PN5180 NFC reader failing to detect tags. Each
activate_type_a() call returning None corrupts the PN5180 transceive
state, silently preventing all subsequent tag detection. Fixed by
performing a full hardware reset (RST pin toggle + RF re-init) before
every idle poll (~240ms, ~1.8 Hz rate). When a tag is present, a light
RF off/on cycle (13ms) resets the card from ACTIVE to IDLE state for
continuous re-selection. Also added error-based recovery, periodic
status logging, and accurate heartbeat NFC/scale health reporting.

won't re-open for dismissed tags, reopens on re-place after removal.
Daemon: Fix PN5180 NFC reader failing to maintain tag detection. After a
successful SELECT the card stays in ACTIVE state and ignores subsequent
WUPA/REQA. Added a conditional RF off/on cycle (13ms) before each poll,
but only when a tag is present — resets card from ACTIVE to IDLE for
re-selection. The cycle is skipped when idle to avoid degrading reader
state with continuous RF toggling, which prevented new tags from being
detected after removal. Also added a preventive full hardware reset every
60s when idle to recover from deeper stuck states, error-based recovery
after 10 consecutive exceptions, and accurate heartbeat reporting of
NFC/scale health.
Frontend: Replace inline SpoolInfoCard/UnknownTagCard with full-screen

Daemon: Fix PN5180 NFC reader failing to maintain tag detection. After a
successful SELECT the card stays in ACTIVE state and ignores subsequent
WUPA/REQA, causing immediate false "tag removed" events. Added a brief
RF off/on cycle (13ms) before each poll to force cards back to IDLE
state. Also added a preventive full hardware reset every 60s when idle
to recover from deeper stuck states where activate_type_a() silently
returns None without exceptions. Heartbeat now reports actual nfc_ok/
scale_ok instead of hardcoded True.
Frontend: Replace inline SpoolInfoCard/UnknownTagCard with full-screen
TagDetectedModal that auto-opens on NFC tag detection. Known spools show
remaining weight, fill bar, and offer "Assign to AMS" (new sub-modal with
printer selector + AMS slot grid) and "Sync Weight". Unknown tags offer
"Add to Inventory" and "Link to Spool". Modal stays open on tag removal,
won't re-open for dismissed tags, reopens on re-place after removal.
Daemon: Fix PN5180 NFC reader silently stopping tag detection. The reader
drifts into a stuck state where activate_type_a() returns None without
raising exceptions, making error-based recovery useless. Changed the
preventive idle maintenance from a lightweight RF off/on cycle to a full
hardware reset (RST pin toggle + RF re-init) every 60s — the same reset
that a service restart performs. Also added error-based auto-recovery
after 10 consecutive exceptions, promoted poll errors to WARNING, added
periodic status logging, and fixed heartbeat to report actual nfc_ok/
scale_ok instead of hardcoded True.

Daemon: Fix PN5180 NFC reader silently stopping tag detection when the
reader drifts into a stuck state. Add auto-recovery (full hardware reset
after 10 consecutive errors), preventive RF cycling every 60s when idle,
and periodic status logging. Heartbeat now reports actual nfc_ok/scale_ok
from reader instances instead of hardcoded True.
The start_bambuddy.bat launcher had Unix (LF) line endings. When a
user's git is configured with core.autocrlf=false or input, the file
is checked out with LF endings and cmd.exe fails with "the syntax of
the command is incorrect" before reaching the hash check.
Add .gitattributes forcing CRLF for *.bat files so they always get
correct line endings on checkout regardless of git config.
The purple queue counter badge in the printer card header used the raw
unfiltered queue item count, so it appeared on ALL printers of the same
model when a job was scheduled for "any [model]" — even printers without
the matching filament color. The PrinterQueueWidget below it (which
shows "Clear Plate & Start") already filtered by filament type + color.
Apply the same filament compatibility filter (type check + color override
check) to the badge count so it only shows on printers that can actually
run the queued jobs.
Enlarge all interactive elements across 9 SpoolBuddy components to meet
44px minimum tap targets on the RPi touchscreen. Increase nav icons
(20→24px), labels (10→12px), bar heights, section headers, printer
buttons, spool visualizations, fill bars, and status indicators.
Compact the dashboard stats bar and remove the printers card. Add
fullScreen prop to ConfigureAmsSlotModal with two-column layout
(filament list left, K-profile + color right) to eliminate scrolling.
When Bambuddy auth is enabled, the SpoolBuddy kiosk gets redirected to
the login page because ProtectedRoute requires a user from GET /auth/me,
which only handled JWT tokens. The kiosk daemon already has an API key
but couldn't use it to satisfy the frontend auth check.
- Backend: /auth/me now accepts API keys (Bearer bb_xxx or X-API-Key)
and returns a synthetic admin UserResponse with all permissions
- Frontend: AuthContext reads ?token= from URL on first load, stores in
localStorage, and strips from URL (prevents history/referrer leakage)
- Install script: kiosk URL now includes ?token=${API_KEY}
- Tests: 3 new integration tests (Bearer API key, X-API-Key header,
invalid key rejection)
When ADC noise kept the spread hovering around the 2g stability
threshold, the stable flag toggled every cycle, forcing a report with
a slightly different weight each time. Now only actual weight changes
of >=2g trigger reports. The stable flag is still included in each
report for consumers that need it.
5 samples at 100ms (500ms window) wasn't enough to smooth NAU7802 ADC
noise — the averaged value still varied by >2g between 1s report
intervals, and the stability state kept flipping, triggering a report
every cycle. Increased to 20 samples (2s window) so noise is smoothed
before reaching the reporting layer.
The daemon imports read_tag and scale_diag as bare modules, but they
live in spoolbuddy/scripts/ which isn't on sys.path when systemd runs
the daemon. Added scripts/ to sys.path at startup, resolved relative
to the module file. Also moved the read_tag import inside NFCReader's
try/except (was crashing the daemon instead of skipping gracefully)
and demoted hardware-not-available messages from ERROR to INFO.
NFCReader.__init__ imported read_tag and instantiated PN5180() outside
the try/except block, so a missing module crashed the entire daemon.
Moved the import inside the existing try/except so the daemon gracefully
skips NFC polling — matching the scale reader's existing behavior.
# Bambuddy v0.2.1
## New Features
- **Multiple Virtual Printers** — Run multiple virtual printers per installation, each with a dedicated bind IP and fully independent FTP, MQTT, SSDP, and Bind servers. Full CRUD API and React UI for creating, editing, and deleting instances. Supports all four modes, any of the 11 printer models, per-instance TLS certificates, and individual network interface override.
- **Background Print Dispatch** ([#112](https://github.com/maziggy/bambuddy/issues/112)) — Printing from archives and the file manager now runs in the background. FTP uploads are decoupled from API request latency, so the UI responds immediately. Real-time progress via WebSocket with per-job upload bars, status badges, and a cancel button.
- **Filament Cost Tracking** ([#452](https://github.com/maziggy/bambuddy/issues/452)) — Track per-spool filament costs and see cost breakdowns for every print. Archive cards display total cost, the print modal shows a real-time cost preview, and the inventory table includes a sortable cost/kg column. A global default filament cost setting provides a fallback. Contributed by @Keybored02.
- **Filament Override for Model-Based Queue** ([#486](https://github.com/maziggy/bambuddy/issues/486)) — When scheduling to "any printer", you can now override the 3MF's original filament choices. The scheduler matches against overridden type and color, preferring printers with exact color matches.
- **Bulk Spool Addition & Stock Spools** ([#480](https://github.com/maziggy/bambuddy/issues/480)) — Quick Add mode for inventorying filament without a slicer profile. Quantity field creates up to 100 identical spools in one transaction. Stock spools shown with an amber badge. New grouping toggle collapses identical unused spools into expandable rows.
- **Developer LAN Mode Detection** — Automatically detects printers without Developer LAN Mode enabled and shows a persistent warning banner with affected printer names and a link to Bambu Lab's documentation.
- **Clear Plate Permission** ([#446](https://github.com/maziggy/bambuddy/issues/446)) — New `printers:clear_plate` permission so users can confirm plate clears without needing full `printers:control`.
- **Full-Page Group Permission Editor** ([#446](https://github.com/maziggy/bambuddy/issues/446)) — Replaced the cramped permission modal with a dedicated full-page editor featuring a 2-column grid, search/filtering, and bulk actions.
- **External Materials & Brands in Spool Form** ([#455](https://github.com/maziggy/bambuddy/issues/455)) — The spool form now allows using custom materials and brands not in the Bambu filament catalog when adding or editing spools.
- **Energy Cost 3-Decimal Precision** ([#416](https://github.com/maziggy/bambuddy/issues/416)) — Energy cost values now support 3 decimal places (e.g., €0.123/kWh) instead of 2, for more accurate cost tracking in regions with fractional energy pricing.
- **Include Beta Updates Setting** — New toggle to opt in to beta/prerelease update notifications. Default: off (stable only).
- **Virtual Printer Dual Bind/Detect Ports** ([#445](https://github.com/maziggy/bambuddy/issues/445)) — The slicer bind/detect handshake now listens on both ports 3000 and 3002 for compatibility across BambuStudio/OrcaSlicer versions.
## Fixed
### Print Queue & Scheduling
- **Queue Empty After Container Restart** ([#523](https://github.com/maziggy/bambuddy/issues/523)) — SQLite WAL not checkpointed on shutdown. Now runs `PRAGMA wal_checkpoint(TRUNCATE)` before exit.
- **Queue Stuck on "Busy" for "Any Model" Jobs** ([#435](https://github.com/maziggy/bambuddy/issues/435)) — Queue API now uses OR logic to also return unassigned items whose `target_model` matches the printer's model.
- **Queue "Any Model" Jobs Stuck in "Waiting" After Plate Clear** ([#435](https://github.com/maziggy/bambuddy/issues/435)) — MQTT raw AMS data returned IDs as strings; fixed type casting.
- **"Queue to Any Printer" Ignores Filament Color Override** ([#486](https://github.com/maziggy/bambuddy/issues/486)) — Now requires at least 1 color match when filament overrides specify colors.
- **"Clear Plate & Start Next" Ignores Filament Override Color** ([#486](https://github.com/maziggy/bambuddy/issues/486)) — Frontend now checks override colors, mirroring the backend's color matching logic.
- **"Clear Plate & Start Next" Shown on Printers Without Correct Filament** ([#527](https://github.com/maziggy/bambuddy/issues/527)) — Widget now filters queue items by filament compatibility.
- **Virtual Printer Queue Sends Wrong Plate ID** ([#529](https://github.com/maziggy/bambuddy/issues/529)) — `plate_id` was always `1`; now extracts plate index from 3MF's `slice_info.config`.
- **Virtual Printer Queue Ignores AMS Mapping** ([#529](https://github.com/maziggy/bambuddy/issues/529)) — Scheduler now computes AMS mapping for all queue items that lack one.
- **Virtual Printer Queue Mode Doesn't Assign Printer** ([#518](https://github.com/maziggy/bambuddy/issues/518)) — Now assigns the VP's target printer or falls back to model-based scheduling.
- **Unnecessary Target Model Selector on "Any" Tab** ([#528](https://github.com/maziggy/bambuddy/issues/528)) — Dropdown hidden when sliced model is known.
- **Print Queue Shows UUID Hash Instead of Filename** ([#438](https://github.com/maziggy/bambuddy/issues/438)) — Library files now display the original human-readable name.
- **SD Card Cleanup After Print Never Runs** ([#374](https://github.com/maziggy/bambuddy/issues/374)) — Used wrong printer object type; fixed to use DB query.
- **Phantom Prints From Lingering SD Card Files** ([#477](https://github.com/maziggy/bambuddy/issues/477)) — Fixed retry loop, added cleanup on `start_print()` failure.
### AMS & Filament
- **AMS History Chart Shows Wrong Time Range** ([#535](https://github.com/maziggy/bambuddy/issues/535)) — X axis now pinned to the full requested time range.
- **Manual Spool Weight Overwritten by AMS Auto-Sync** ([#525](https://github.com/maziggy/bambuddy/issues/525)) — Added `weight_locked` flag for manual weight entries.
- **AMS Slot Auto-Config Falls Back to Generic Instead of Spool's Preset** — Fixed PFUS*/P* custom preset handling and "sticky" generic ID reuse.
- **PCTG Filament Misidentified as PC** ([#478](https://github.com/maziggy/bambuddy/issues/478)) — Reordered material parser; added PCTG to all material type arrays.
- **External Spool Mapping Inverted on H2C** ([#492](https://github.com/maziggy/bambuddy/issues/492)) — Now uses `active_extruder` on dual-nozzle printers.
- **External Spool Assignments Lost on Restart** ([#493](https://github.com/maziggy/bambuddy/issues/493)) — Now looks up external assignments in `vt_tray` data.
- **Filament Fill Level Wrong / Missing for External Spools** ([#496](https://github.com/maziggy/bambuddy/issues/496)) — Fixed priority chain, removed misleading gray fallback bar, added AMS remain fallback for external spools.
- **Wrong AMS Unit Displayed With Dual AMS on P2S** ([#420](https://github.com/maziggy/bambuddy/issues/420)) — Now cross-references `tray_now` with MQTT mapping field for multi-AMS printers.
- **H2D Tray Disambiguation Produces Bogus IDs for AMS-HT** ([#364](https://github.com/maziggy/bambuddy/issues/364)) — Fixed AMS-HT global tray ID computation across multiple code paths.
- **Usage Tracking Wrong Spool on Multi-AMS Printers** ([#364](https://github.com/maziggy/bambuddy/issues/364)) — Now decodes MQTT mapping field from snow encoding for universal spool resolution.
- **Spool Usage Lost When Spool Runs Empty Mid-Print** ([#459](https://github.com/maziggy/bambuddy/issues/459)) — Snapshots assignments at print start; splits weight across trays using per-layer gcode data.
- **Spool Form Allows Empty Brand & Subtype** ([#417](https://github.com/maziggy/bambuddy/issues/417)) — Brand and Subtype now mandatory.
### Printing & Archives
- **Inconsistent Print Cost on Reprints** ([#505](https://github.com/maziggy/bambuddy/issues/505)) — Removed redundant cost paths; now computes from current session only.
- **Finish Photo Not Captured When Archive Has No Source 3MF** ([#484](https://github.com/maziggy/bambuddy/issues/484)) — Falls back to `archive/{id}/` directory.
- **Finish Photo Not Shown for BambuStudio Prints** ([#474](https://github.com/maziggy/bambuddy/issues/474)) — Fixed path resolution for empty `file_path`.
- **Archive Endpoints Crash With "Is a directory"** ([#475](https://github.com/maziggy/bambuddy/issues/475)) — Replaced `.exists()` with `.is_file()` across 15 locations.
- **File Manager Rename Doesn't Update Displayed Name** ([#460](https://github.com/maziggy/bambuddy/issues/460)) — Rename now also updates `print_name` in file metadata.
- **"Open in Slicer" Fails for Special Characters** — Sanitizes `/`, `\`, `?`, `#` to `_` in slicer download URLs.
- **"Open in Slicer" Fails When Auth Enabled** ([#421](https://github.com/maziggy/bambuddy/issues/421)) — Added short-lived, single-use download tokens with platform-specific URL formats.
- **Non-Actionable HMS Errors Triggering Notifications** ([#470](https://github.com/maziggy/bambuddy/issues/470)) — Suppresses MQTT auth failures, cloud connection failures, and user cancellations.
- **ntfy Notifications Fail With "Illegal header value"** ([#466](https://github.com/maziggy/bambuddy/issues/466)) — Escapes newlines in HTTP headers; retries without image when attachments disabled.
- **Print Bed Cooled Notification Never Triggers** ([#497](https://github.com/maziggy/bambuddy/issues/497)) — Moved bed cooldown monitor before archive lookup early-return.
- **K-Profile Response Race Condition Crash** ([#462](https://github.com/maziggy/bambuddy/issues/462)) — Fixed TOCTOU race between MQTT callback and asyncio thread.
### Permissions & UI
- **"Power Off Printer" Not Gated by Control Permission** ([#500](https://github.com/maziggy/bambuddy/issues/500)) — Checkbox now disabled for users without `printers:control`.
- **Created Admin Users Can't See Settings Button** ([#503](https://github.com/maziggy/bambuddy/issues/503)) — Now uses `hasPermission('settings:read')` instead of hardcoded role check.
- **Settings Text Fields Reset While Typing** — Removed stale state overwrite from auto-save handler.
- **Spool Form Profile Dropdown Truncates Long Names** ([#534](https://github.com/maziggy/bambuddy/issues/534)) — Removed inline filament codes; widened modal.
### Timestamps & Dates
- **Timestamps Off by Timezone Offset in Non-UTC Containers** ([#504](https://github.com/maziggy/bambuddy/issues/504)) — Replaced `datetime.now()` / `datetime.utcnow()` with `datetime.now(timezone.utc)` across 16 files (~80 call sites). Fixed 13 frontend `new Date()` calls.
- **Inventory Date Format Ignores Settings** ([#463](https://github.com/maziggy/bambuddy/issues/463)) — Now respects date format setting.
- **Inventory Location Shows Garbled Characters for AMS-HT Slots** ([#463](https://github.com/maziggy/bambuddy/issues/463)) — Now uses shared `formatSlotLabel()` utility.
### Docker & Infrastructure
- **FTP Proxy Cannot Bind to Port 990 in Docker** — `cap_add: NET_BIND_SERVICE` didn't reliably propagate with the `user:` directive. Now sets file capabilities via `setcap` in the Dockerfile.
- **Support Bundle Leaking Personal Data** ([#473](https://github.com/maziggy/bambuddy/issues/473)) — Now queries DB for sensitive values; uses httpx `auth` parameter for smart plug credentials; redacts serial numbers fully.
- **IP Addresses Not Redacted From Support Bundle** — Added IPv4 regex that preserves firmware version strings.
### AMS Mapping & Dual-Nozzle (H2D/H2C)
- **7 AMS Mapping Fixes** — Hard nozzle filter, external spool extruder, `ams_extruder_map` race condition, `group_id` priority, dual-nozzle detection, AMS-HT `globalTrayId`, dropdown nozzle filter.
- **Nozzle Mapping Uses Wrong Source in 3MF** — Now uses `group_id` as primary source instead of `filament_nozzle_map`.
- **H2D Tray Disambiguation Triggers on Single-Nozzle Printers** — Now uses persistent `_is_dual_nozzle` flag.
- **Cancelled Print Usage Tracking Uses Stale Progress** — Now captures last valid progress/layer during printing.
- **Developer Mode Detection Always Reports Null** — Fixed `int(value, 16)` TypeError on integer MQTT field.
### Other
- **Wrong Documentation Link for "Lubricate Carbon Rods" on P2S** ([#490](https://github.com/maziggy/bambuddy/issues/490))
- **"Unknown stage (74)" on H2D** — Mapped stage 74 ("Preparing") and 77 ("Preparing AMS").
- **Color Tooltip Clipped Behind Adjacent Swatches** — Added z-index.
- **PAUSED State Never Matched** ([#447](https://github.com/maziggy/bambuddy/issues/447)) — Removed dead `PAUSED` checks; printer only sends `PAUSE`.
## Improved
- **Queue API Returns More Print Metadata** ([#524](https://github.com/maziggy/bambuddy/issues/524)) — Endpoints now include `filament_type`, `filament_color`, `layer_height`, `nozzle_diameter`, and `sliced_for_model`.
- **Filament Catalog API Renamed** ([#427](https://github.com/maziggy/bambuddy/issues/427)) — `/api/v1/filaments/` → `/api/v1/filament-catalog/` for clarity.
- **Clear Plate Dot Indicator on Sidebar** — Yellow dot on Printers icon when plate clear is needed.
- **Inventory Sidebar Always Visible** — Shows Spoolman iframe or internal inventory based on mode.
- **Queue Page Mobile Responsiveness** — Improved layout for mobile devices.
- **Storage Size Formatting & Overdue Queue Items** — UI polish and i18n fixes.
- **Brazilian Portuguese Translation** — Full translation contributed by @wreuel.
- **H2D Pro Printer Image** — Added H2D Pro image and model mapping. Contributed by @cimdDev.
- **Native Updater Script** — Systemd-based updater with backup and safety checks. Contributed by @uefigs139.
- **Docker Install iptables Option** — Option to add iptables port redirect during Docker install. Contributed by @wreuel.
- **Frontend Pre-Commit Hooks** ([#458](https://github.com/maziggy/bambuddy/issues/458)) — TypeScript type checking and ESLint on staged frontend files.
- **Show Remaining Spool Weight** — Displays remaining weight instead of used weight. Contributed by @Keybored02.

cap_add: NET_BIND_SERVICE in docker-compose.yml doesn't reliably
propagate to the Python process when combined with the user: directive
(depends on ambient capability support in the container runtime).
Set the file capability directly on the Python binary via setcap in
the Dockerfile, which the kernel honors regardless of runtime config.
The chart X axis used dataMin/dataMax domain, compressing the view to
only the data present. A 6h view with 1.5h of data looked like 1.5h.
Pin the X axis to the full selected time range, pad data edges so the
line extends to both ends, and connect through nulls for a continuous
line.
When a print was queued to "any printer" with a filament color override
(e.g., white PETG), the "Clear Plate & Start Next" button appeared on
printers that had the right type but wrong color. The backend scheduler
already rejected color mismatches, but the frontend only checked filament
types. Now passes loaded type+color pairs from AMS status to the widget
and filters against filament_overrides, mirroring the backend's
_count_override_color_matches() logic.
The SQLite WAL was never checkpointed during container shutdown, leaving
uncommitted data (including schema migrations) in the -wal file. On
restart, partial WAL recovery could cause inconsistent query results,
making the queue appear empty until a filter was applied. Add
PRAGMA wal_checkpoint(TRUNCATE) and engine.dispose() to the lifespan
shutdown handler.
Long filament profile names were cut off because inline filament ID
codes consumed horizontal space in the dropdown. Remove the codes from
dropdown items (selected code still shown below the input) and widen
the modal from max-w-lg to max-w-xl.
The print scheduler had two code paths for queue items: model-based
(target_model set) and printer-specific (printer_id set). Only the
model-based path computed ams_mapping before starting the print. VP
queue items assigned to a specific printer went through the
printer-specific path with null ams_mapping, causing the printer to
default to the first AMS slot regardless of what the 3MF required.
Add _compute_ams_mapping_for_printer() call to the printer-specific
path, matching the existing model-based behavior.
When a virtual printer auto-queued a file, PrintQueueItem was created
without plate_id. The scheduler defaulted to plate_id=1, generating
MQTT path "Metadata/plate_1.gcode". For multi-plate 3MF files sliced
on a different plate, the printer couldn't find the gcode and returned
HMS error 0500_4003. Extract plate index from the 3MF's slice_info.config
before creating the queue item.
When scheduling a print to "Any {model}", a redundant "Target Model"
dropdown appeared even though the G-code is already sliced for a
specific printer model. Changing it would lead to print failures.
Hide the dropdown when slicedForModel is known — the tab label already
communicates the target. The dropdown still appears as a fallback for
legacy files without model metadata.
The "Clear Plate & Start Next" button appeared on ALL printers of a
model when a job was queued via "Queue to Any X", even printers without
the required filament loaded. Clicking it started a print that fails.
PrinterQueueWidget now filters queue items by filament compatibility —
each item's required_filament_types must all be present in the printer's
loaded filaments (AMS + external spools). If no compatible items exist,
the widget is hidden entirely. Matching is type-only (not color) and
case-insensitive, consistent with the backend scheduler. When filament
data is unavailable, no filtering is applied (graceful degradation).
Add weight_locked flag to spools that auto-sets when weight_used is
explicitly updated via the API. Both the MQTT AMS remain% auto-sync and
the manual force-sync endpoint skip locked spools. Usage tracker delta
tracking is unaffected. Users can re-enable AMS sync by setting
weight_locked to false.
Queue endpoints now return filament_type, filament_color, layer_height,
nozzle_diameter, and sliced_for_model from the archive or library file.
Previously this data was only available via the archive API.
