Problem: At print start, the MQTT mc_remaining_time was often 0 or unavailable because the printer hadn't fully processed the gcode yet.
Solution: Modified the notification system to prioritize the print_time_seconds from the 3MF file parsing (which is always available after archive creation) over the
MQTT remaining time.
Files changed:
- backend/app/services/notification_service.py:
- Added optional archive_data parameter to on_print_start() method
- Added priority logic: archive data > MQTT remaining_time > raw_data mc_remaining_time
- backend/app/main.py:
- Created _send_print_start_notification() helper function
- Moved notification sending to AFTER archive creation (when print_time_seconds is available)
- Added fallback notification sending at early return points (auto_archive disabled, file not found, etc.)
Issue 2: Timelapse Auto-Assignment
Problem: Timelapses couldn't be auto-assigned reliably because printer dates could be off in LAN-only mode, making timestamp matching unreliable.
Solution: Track whether timelapse recording was active during the print via MQTT, and if so, auto-fetch the most recent timelapse file on print completion.
Files changed:
- backend/app/services/bambu_mqtt.py:
- Added _timelapse_during_print instance variable
- Track when timelapse is active during a print (in both data and xcam parsing)
- Reset the flag on new print start
- Include timelapse_was_active in the print complete callback data
- backend/app/main.py:
- Added timelapse auto-scan logic in on_print_complete()
- If timelapse_was_active is True and status is "completed":
- Wait 5 seconds for timelapse to finalize
- Scan printer's timelapse directory
- Find most recent file by mtime
- Verify it was modified within 30 minutes of print completion
- Download and attach to archive
- Send WebSocket update
- Separate AMS and AMS-HT notification switches (one per device type)
- Fix notification variables not showing (duration, filament, estimated_time)
- Add fallback values for empty notification variables ("Unknown" instead of blank)
Settings:
- Fix API keys badge count only showing after visiting tab
- Move External Links card to third column above Updates
- Add Release Notes modal for viewing full notes before updating
Statistics:
- Fix filament usage trends not showing (wrong API parameters)
- Move dashboard controls (Hidden, Reset Layout) to header row
- Remove duplicate Reset Layout button
Camera:
- Fix ffmpeg processes not killed when closing webcam window
- Add /camera/stop endpoint with POST support for sendBeacon
- Track active streams and proper cleanup on disconnect
Backend:
- pytest configuration with async support and coverage
- Unit tests for notification service (23 tests)
- Unit tests for smart plug manager (12 tests)
- Unit tests for archive service (16 tests)
- Integration tests for API endpoints
- Fix: notifications now send immediately (digest is summary only)
Frontend:
- Vitest configuration with jsdom and coverage
- MSW for API mocking
- Component tests for Toggle, Button, Card, ConfirmModal (77 tests)
- Test utilities with custom render wrapper
CI/CD:
- GitHub Actions workflow for automated testing
- Backend lint, unit tests, integration tests
- Frontend lint, type-check, unit tests, build
