- Remove created_at from backup_metadata.json
- Remove exported_at from K-profile files
- Remove exported_at from cloud profile files (filament, printer, process)
- Remove exported_at from app settings backup
- Git already tracks file modification history, so these were redundant
- Backups now only show changes in git diff when actual data changes
Add new setting "Check printer firmware" in Settings → General → Updates
that allows users to disable automatic firmware update checks from
Bambu Lab servers.
Closes#169
Some A1/A1 Mini firmware versions incorrectly report stg_cur=0 (which
maps to "Printing") even when the printer is idle. This is a known
firmware bug also observed in the Home Assistant Bambu Lab integration.
- Add A1_MODELS constant listing affected model variants
- Add has_stg_cur_idle_bug() helper to identify affected models
- Update get_derived_status_name() to check gcode_state before stg_cur
for A1 models: if IDLE + stg_cur=0, return None to show "Idle"
- Fix only applies when all conditions match (A1 model + IDLE + stg_cur=0)
- Non-A1 printers and A1 printers without the bug are unaffected
Closes#168
- Queue now shows correct plate thumbnail based on selected plate_id
(previously always showed plate 1 regardless of selection)
- Archive cards now support plate browsing for multi-plate 3MF files:
- Left/right arrows to cycle through plates on hover
- Dot indicators at bottom show current plate (clickable)
- Lazy-loads plate data only when user hovers
- Added getArchivePlateThumbnail and getLibraryFilePlateThumbnail API methods
Closes#166
The GitHub backup settings page was showing "1/2 connected" even when
both printers were connected. This happened because the code read
printer status from the React Query cache, which is only populated by
WebSocket messages received on other pages.
Changed to use useQueries to fetch printer status directly from the API
(/api/v1/printers/{id}/status) instead of relying on cached WebSocket
data. Results are cached for 10s and refreshed every 30s.
Printers report filament_id (e.g., GFA00) but the Bambu Cloud API expects
setting_id format which has an "S" inserted after "GF" (e.g., GFSA00).
- Add _filament_id_to_setting_id() helper function
- Transform IDs before API calls: GFx## -> GFSx##
- User presets (P-prefix) and already-correct IDs unchanged
- Improved warning message to show both original and transformed IDs
- Changed stale-issue-label from feedback to stale (so stale issues get the "stale" label)
- Added remove-issue-labels: 'feedback' to remove the feedback label when issues are auto-closed
- Changed stale-issue-label from feedback to stale (so stale issues get the "stale" label)
- Added remove-issue-labels: 'feedback' to remove the feedback label when issues are auto-closed
Expose printer telemetry at /api/v1/metrics in Prometheus text format for
integration with Grafana, Prometheus, and other monitoring systems.
Backend:
- Add metrics.py route with GET /api/v1/metrics endpoint
- Support optional bearer token authentication
- Export printer metrics: connection, state, temperatures, fans, WiFi
- Export print metrics: progress, remaining time, layer count
- Export statistics: prints by status, filament used, print time
- Export queue metrics: pending and active jobs
- Add prometheus_enabled and prometheus_token settings
Frontend:
- Add Prometheus Metrics card in Settings → Network tab
- Toggle to enable/disable metrics endpoint
- Optional bearer token field for authentication
- Display list of available metrics
Tests:
- Add test_metrics_api.py with 7 integration tests
- Test access control (disabled, enabled, token auth)
- Test metrics format and content validation
- Add draggable resize handle to folder sidebar (200-500px range)
- Persist sidebar width in localStorage
- Double-click resize handle to reset to default width
- Add "Wrap" toggle button in Folders header for text wrapping
- When wrap enabled: folder names break across lines, menu always visible
- When wrap disabled: folder names truncate with tooltip on hover
- Persist wrap preference in localStorage
Closes#160
- Automatically turn on chamber light before plate check if it's off
- Restore light to original state after modal closes or check completes
- Add 2.5s delay for light to turn on and camera to adjust exposure
- Remove manual light warning from plate check modal
- Apply to both manual plate checks (modal) and automatic checks on print start
The print queue now supports two sources:
- archive_id: Print from existing archive (existing behavior)
- library_file_id: Print from file manager library files (NEW)
Previously, queue items from the file manager failed with "Archive not
found" because the scheduler only handled archive-based prints.
Changes:
- Add LibraryFile model import
- Update _start_print() to handle both archive and library file sources
- Handle absolute vs relative file paths correctly
- Update logging and MQTT notifications to use correct filename
Fixes GitHub issue #163
The scheduler compared timezone-aware datetime.now(UTC) with naive
datetimes from the SQLite database, causing "can't compare offset-naive
and offset-aware datetimes" error.
Fixed by adding UTC timezone to naive datetimes before comparison.
The print scheduler only considered IDLE, FINISH, and unknown as valid
idle states. This caused the queue to not process items when the printer
was in FAILED state (e.g., after an aborted print).
Added FAILED to the list of idle states since a failed print means the
printer is ready to accept a new print job.
New feature to automatically backup K-profiles, cloud profiles, and app
settings to a GitHub repository with scheduled or on-demand execution.
Features:
- Configure GitHub repo URL and Personal Access Token
- Schedule backups hourly, daily, or weekly (background scheduler)
- Manual backup trigger with real-time progress tracking
- Skip unchanged commits (only creates commit when data changes)
- Backup history log with status and commit links
- Requires Bambu Cloud login for full profile access
- New Settings → Backup & Restore tab consolidating all backup options
- GitHub backup config included in local backup/restore (except PAT)
Backend:
- New models: GitHubBackupConfig, GitHubBackupLog
- New service: GitHubBackupService with scheduler and GitHub API client
- New routes: /github-backup/* for config, status, logs, and triggers
- Updated settings.py to include github_backup in backup/restore
Frontend:
- New GitHubBackupSettings.tsx component with auto-save
- Updated SettingsPage with Backup tab and status indicator
- Added API types and methods to client.ts
Tests:
- Backend integration tests for all GitHub backup API endpoints
- Frontend API type and endpoint tests
- Add "Plate Detection" option to backup modal
- Store printer_id_to_serial mapping in backup for calibration files
- Remap printer IDs during restore based on serial numbers so files
like printer_3_ref_0.jpg get correctly renamed if printer 3 becomes
printer 2 on the new system
- Add parents=True to mkdir calls in config.py to fix startup crash
- Labels/metadata are now correctly restored via the metadata.json files
- Add "Plate Detection" option to backup modal for exporting empty plate
reference images (requires Printers to be selected)
- Add parents=True to mkdir calls in config.py to create full directory
tree on first run (fixes startup crash when data dir doesn't exist)
- Update BackupModal test to use exact match for "Printers" text
- Check cv2.imwrite() return value to catch silent failures
- Verify reference image file exists after save
- Validate file size is reasonable (>1KB) to detect corruption
- Add logging for save, rotate, and delete operations
- Use temp directory for plate calibration during tests to avoid
deleting real user calibration files
Previously, calibration could report success even if the image file
failed to save. Additionally, running tests would delete real
calibration files because tests shared the same plate_calibration_dir.
New Features:
- Queue bulk edit: Select multiple pending items and edit printer
assignment, print options, or cancel them at once (Issue #159)
- Tri-state toggles (unchanged/on/off) for selective field updates
Fixes:
- Progress milestone notifications showed wrong time (e.g., "17m" instead
of "17h 47m") - fixed by converting remaining_time from minutes to
seconds (Issue #157)
- File Manager folder names now show full name on hover tooltip (Issue #160)
Backend:
- Added PATCH /queue/bulk endpoint for bulk updates
- Route ordering fixed to prevent /bulk matching as /{item_id}
Frontend:
- Added checkbox selection to pending queue items
- Added bulk action toolbar with Select All, Edit Selected, Cancel Selected
- Created BulkEditModal with tri-state toggles for each setting
Tests:
- Added 7 integration tests for bulk update endpoint
Closes#159
The remaining_time from printer state is in minutes (from mc_remaining_time),
but _format_duration() expects seconds. This caused "17h 47m" to display as
"17m" in milestone notifications.
Closes#157
