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.
All backend timestamps used datetime.now() (server local time) or the
deprecated datetime.utcnow(). The frontend's parseUTCDate() assumes
timestamps without timezone indicators are UTC and appends 'Z', so
stored timestamps were off by the timezone offset when the container's
timezone wasn't UTC.
Backend: replaced datetime.now() and datetime.utcnow() with
datetime.now(timezone.utc) across 16 files (~80 call sites) for all
database fields and DB comparisons. Cosmetic timestamps (filenames,
user-facing local time formatting) intentionally left as local time.
Frontend: replaced 13 new Date(backendTimestamp) calls with
parseUTCDate() across 8 files to correctly interpret UTC timestamps.
The "Power off printer when done" checkbox in the print modal and the
auto power off tri-state toggle in the bulk edit modal were accessible
to all users regardless of permissions. Users without printers:control
can now no longer enable auto power off — controls are disabled and
visually dimmed.
When scheduling a print to "any printer" (model-based assignment),
users can now override the 3MF's original filament choices per slot.
The override dropdown shows compatible filaments loaded across all
printers of the selected model, filtered by type and nozzle (H2D).
The scheduler matches against overridden type/color instead of the
original 3MF values, preferring printers with exact color matches.
Backend:
- New GET /printers/available-filaments endpoint (aggregates loaded
filaments across printers of a model, includes extruder_id for
dual-nozzle nozzle-aware filtering)
- New filament_overrides JSON column on print_queue table
- Scheduler applies overrides before AMS mapping, clears tray_info_idx
on overridden slots so color matching takes priority
- Printer selection prefers printers with most override color matches
Frontend:
- New FilamentOverride component with per-slot override dropdowns
- Type-filtered options (PLA slots only show PLA)
- Nozzle-aware filtering (H2D: only shows filaments on correct extruder)
- Integrated into PrintModal for model-based queue mode
Tests:
- 11 backend unit tests (color match counting, override application)
- 12 frontend tests (rendering, type/nozzle filtering, interactions)
i18n: All 6 locales (en, de, fr, it, ja, pt-BR)
This allows users sending particularly large prints to slow printers such as the P1-series to start a print and then move onto another task in Bambuddy immediately (such as starting more prints on more printers). It also gives the user visibility into what's happening instead of a loading indicator appearing for an indefinite period of time.
The new toast-based UI uses websockets to update in real time. It will also appear for other users / instances of Bambuddy, not just the user who started the prints, allowing more transparency and handling cases where the user closes the page and then comes back wanting to know the status of the dispatching.

- 5 backend tests: cancel_job single-lock TOCTOU, batch reset re-check,
job lifecycle
- 2 FTP regression tests: voidresp error handling (upload-loop fix),
A1 model voidresp skip
- 1 frontend test: reprint toast suppression
- CHANGELOG: background dispatch feature + test coverage entries
- README: add background dispatch to Scheduling & Automation
- Website: add feature item to Automation section
- Wiki: add Background Print Dispatch section to print-queue.md
- Add progress bar, time remaining, ETA, and layer count to currently printing item
- Remove duplicate formatDuration & formatETA functions, now imported from utils/dates
- Remove formatTime (duplicate of formatDuration)
- Update formatETA to support optional i18n translation
- Update translation: common.tomorrow
When scheduling a multi-plate file from the file manager, the modal
allowed submission without selecting a plate. Now auto-selects the
first plate by default and enforces plate selection for both archive
and library files.
Dual-nozzle H2D/H2D Pro: filament matching now respects nozzle assignments
from the 3MF file. Each AMS unit feeds a specific nozzle (L/R), and the
scheduler/frontend constrain matching to only trays on the correct nozzle.
Falls back to unfiltered matching when no trays exist on the target nozzle.
L/R badges shown in the filament mapping UI. Translated in en/de/ja/it.
Fix AMS slot config overwritten on startup: on_ams_change unconditionally
unlinked BL spool assignments on every MQTT pushall, then re-assigned them
sending ams_filament_setting without setting_id — clearing the printer's
filament preset. Now compares spool RFID identifiers before unlinking.
Fix BL spool detection false positives: removed tray_info_idx from detection
logic in both backend is_bambu_lab_spool() and frontend isBambuLabSpool().
Third-party spools using Bambu generic presets had GF-prefixed tray_info_idx
values, causing misidentification. Now uses only tray_uuid and tag_uid.
SQLite WAL mode with 5s busy timeout reduces "database is locked" errors.
When editing a queue item, the scheduled time was being displayed in UTC
instead of the user's local timezone. This caused confusion where:
- User selects April 2, 2:00 PM local time
- After saving, it appears shifted by their timezone offset
- Month/day could appear swapped due to the timezone difference
The fix converts the UTC time from the server to local time when
populating the datetime-local input, using toDateTimeLocalValue()
instead of toISOString().slice(0, 16).
Closes#233
- Added query to fetch library file details in PrintModal
- Updated backend FileResponse schema to include metadata fields (print_name, print_time_seconds, filament_used_grams, sliced_for_model)
- Updated backend get_file endpoint to extract and return metadata fields
- Updated frontend LibraryFile interface to include metadata fields
- Now slicedForModel is properly extracted from both archives and library files

Issue #233: Respect user date/time format in queue scheduler
- Replace native datetime-local input with custom text inputs
- Add date parsing/formatting utilities for US, EU, ISO, and system formats
- Add calendar button that opens native picker for convenience
- Pass dateFormat and timeFormat settings to ScheduleOptionsPanel
- Show format-appropriate placeholders (MM/DD/YYYY, DD/MM/YYYY, etc.)
Closes#233

Closes#104
- Print from File Manager with plate selection, AMS mapping, and print options. Closes#94
- Add to queue without creating archive (reduces clutter)
- Queue displays library file name, thumbnail, and print time
Fixes:
Queue items from File Manager now reference library files directly instead of
creating archives upfront. Archives are created automatically when prints start.
Added ability to send prints or queue items to multiple printers at once:
- Checkbox selection for multiple printers in reprint and add-to-queue modes
- "Select all" / "Clear" buttons for quick printer selection
- Same filament slot mapping applies to all selected printers
- Progress indicator during multi-printer submission (e.g., "Sending 2/3...")
- Info message: "Slot mapping below applies to all N printers"
- Ideal for print farms with identical filament configurations
Implementation:
- Added multi-select props to PrinterSelector component
- Added computeAmsMapping() utility function for imperative AMS mapping
- Updated PrintModal to handle array of selected printers
- Created unified PrintModal.test.tsx replacing three separate test files
Closes#104
