When reprinting a multi-plate 3MF file exported with "All sliced file",
the system now asks which plate to print and only maps filaments for
that specific plate.
Backend changes:
- Add GET /archives/{id}/plates endpoint to list available plates
with thumbnails, print times, and per-plate filament requirements
- Add GET /archives/{id}/plate-thumbnail/{index} for plate thumbnails
- Update GET /archives/{id}/filament-requirements to accept plate_id
query parameter for filtering filaments by plate
- Add plate_id field to ReprintRequest schema
- Update POST /archives/{id}/reprint to use plate_id from request body
instead of auto-detecting (maintains backward compatibility)
Frontend changes:
- Add getArchivePlates API method
- Update getArchiveFilamentRequirements to accept optional plateId
- Update reprintArchive to accept plate_id in options
- Add plate selection UI to ReprintModal when multi-plate 3MF detected
- Show plate thumbnails, names, and filament counts in selection grid
- Require plate selection before printing multi-plate files
- Filter filament requirements to show only selected plate's filaments
Tests:
- Add unit tests for multi-plate slice_info.config parsing
- Add unit tests for plate detection from gcode files
- Add integration tests for new plate endpoints
When exporting individual plates from a multi-plate 3MF in Bambu Studio,
all uploaded archives showed plate 1's name and thumbnail regardless of
which plate was actually exported.
Root cause: The 3MF parser used an incorrect XPath lookup (plate_idx
attribute) and didn't extract the plate index from slice_info.config
metadata.
Changes:
- Extract plate index from <metadata key="index" value="N"/> in
slice_info.config
- Remove incorrect plate[@plate_idx='N'] XPath lookup that doesn't
work for single-plate exports
- Set self.plate_number from extracted index so _extract_thumbnail()
uses the correct plate thumbnail (e.g., plate_5.png instead of
plate_1.png)
- Append " - Plate N" to print_name when plate index > 1 to
distinguish multi-plate exports
- Add 7 unit tests for plate index extraction and print_name
enhancement
Track individual parts/objects separately from print plates in projects.
Useful for multi-part builds like Voron where 25 plates produce 150 parts.
Backend:
- Add target_parts_count field to Project model
- Calculate parts_progress_percent and remaining_parts in stats
- Auto-detect quantity from 3MF printable objects when archiving
- Sum archive quantities for completed_count (parts)
- Use archive_count for plates progress
Frontend:
- Add "Target Parts" input in project create/edit modal
- Show separate progress bars for plates vs parts
- Stats footer displays both plates and parts count
- Header badge shows parts progress when target set
Scripts:
- Add update_archive_quantities.py to migrate existing archives
Tests:
- Add 5 integration tests for parts tracking
- Add 3 unit tests for 3MF object extraction
Closes#85
Fix Applied:
1. Added supports_chamber_temp() helper function that returns True only for X1/X1C/X1E, P2S, and H2 series
2. Modified printer_state_to_dict() to filter out chamber, chamber_target, chamber_heating from temperatures for unsupported models
3. Added model caching in PrinterManager so we can look up the model without a database query
4. Updated all callers (main.py, websocket.py) to pass the model
The chamber temperature widget will now simply not appear for P1S/P1P/A1/A1Mini printers since the temperatures.chamber field won't be sent to the frontend.

1. "Unknown Status (255)" bug
File: backend/app/services/printer_manager.py:291-293
Problem: A1/P1 printers send stg_cur=255 when idle (unlike X1 which uses -1). The code treated 255 as a valid stage number and returned "Unknown stage (255)".
Fix: Changed the condition from if state.stg_cur >= 0: to if 0 <= state.stg_cur < 255: so that 255 is now treated as "no calibration stage" (same as -1).
2. AMS humidity/temp displaced on mobile
File: frontend/src/pages/PrintersPage.tsx:1164-1212
Problem: The AMS row used a rigid horizontal flex layout that didn't adapt to narrow mobile screens, causing humidity/temperature indicators to be displaced.
Fix:
- Added flex-wrap to allow wrapping on very narrow screens
- Added ml-auto to humidity/temp section to keep it right-aligned
- Added max-w-[60px] sm:max-w-none to truncate long filament names on mobile
- Changed gap from fixed gap-3 to responsive gap-2 sm:gap-3
Tests Added
4 new unit tests for get_derived_status_name:
- test_stg_cur_255_returns_none - Verifies A1/P1 idle state
- test_stg_cur_negative_one_returns_none_when_idle - Verifies X1 idle state
- test_valid_stage_returns_name - Verifies valid stages work
- test_stg_cur_zero_returns_printing - Verifies printing state
All 382 tests pass.
Problem: xcam data was parsed BEFORE _was_running was set to True, so timelapse detection failed when both arrived in the same message.
Fix: Added timelapse detection at two critical points:
# Lines 1375-1381: When entering RUNNING state
if self.state.state == "RUNNING" and current_file:
if not self._was_running:
if self.state.timelapse:
self._timelapse_during_print = True
logger.info(f"[{self.serial_number}] Timelapse detected when entering RUNNING state")
# Lines 1391-1399: When print start detected
if self.state.timelapse:
self._timelapse_during_print = True
logger.info(f"[{self.serial_number}] Timelapse detected at print start")
2. Callback Error Handling (main.py + printer_manager.py)
Problem: The on_print_complete callback was hanging silently - no logs after "Found archive".
Fixes:
- Added try/except wrapper around "Update archive status" section (line 749-767)
- Added [CALLBACK] log messages at start and end of callback
- Added exception handler to _schedule_async in printer_manager.py to log any exceptions from async callbacks
3. New Integration Tests (test_bambu_mqtt.py)
Added TestRealisticMessageFlow class with 5 new tests that simulate real MQTT message sequences:
1. test_timelapse_detected_at_print_start_in_same_message - The critical race condition test
2. test_timelapse_not_detected_when_disabled
3. test_timelapse_detected_when_enabled_after_print_start
4. test_print_complete_includes_timelapse_flag_full_flow - Full lifecycle test
5. test_print_failed_includes_timelapse_flag
These tests process messages through _process_message() with proper {"print": {...}} wrapping, matching real MQTT flow.
Files Modified:
- backend/app/services/bambu_mqtt.py - Timelapse race condition fix
- backend/app/main.py - Error handling + logging for on_print_complete
- backend/app/services/printer_manager.py - Exception capture in _schedule_async
- backend/tests/unit/services/test_bambu_mqtt.py - New integration tests
Next Steps
You should restart the application to apply these changes. The next print will show:
- [CALLBACK] on_print_complete started for printer X
- [ARCHIVE] Updating archive X status...
- [ENERGY], [PHOTO], [AUTO-OFF] logs (if those features trigger)
- [CALLBACK] on_print_complete finished for printer X, archive X
