The print scheduler was hardcoded to use Tasmota service when powering
on printers for queued prints. Home Assistant plugs were not checked,
causing "Tasmota device not found" errors.
Changes:
- Make get_service_for_plug() public in smart_plug_manager
- Update print_scheduler to use smart_plug_manager.get_service_for_plug()
instead of tasmota_service directly
- Fixes both _power_on_and_wait() and _power_off_if_needed() methods
Closes#200
- Implemented batch STL thumbnail generation API endpoint.
- Added Pydantic schemas for batch thumbnail requests and responses.
- Created service for generating thumbnails from STL files using trimesh and matplotlib.
- Updated file upload and ZIP extraction endpoints to include thumbnail generation option.
- Enhanced frontend to support STL thumbnail generation during file uploads and ZIP extractions.
- Added integration and unit tests for the new thumbnail generation features.
- Updated requirements to include necessary libraries for STL processing.
Transparent spools (like Natural PLA Support) report color "00000000"
which was being skipped as invalid. Now these spools are synced with
a light cream color (F5E6D3) that represents how natural PLA looks.
Fixes#190
Backend - X1E model-based queue support:
- Fix 'PrinterState' object has no attribute 'ams_units' error
by accessing AMS data via status.raw_data.get("ams", [])
- Add model name normalization in print_queue.py to convert
"Bambu Lab X1E" or "C13" to canonical "X1E" format
- Add case-insensitive model matching in print_scheduler.py
using func.lower() for database queries
Fixes#162
The _get_missing_filament_types() method was incorrectly accessing
status.ams_units and status.virtual_tray, but PrinterState stores
this data in raw_data["ams"] and raw_data["vt_tray"] respectively.
This caused "'PrinterState' object has no attribute 'ams_units'" error
when using model-based queue assignment with filament type requirements.
Fixes#162
Enhance Home Assistant script support with automation triggers and
printer card visibility control.
- Script automation: Run scripts automatically when main plug turns on/off
- Show/hide scripts on printer cards (configurable per script)
- Scripts appear in dedicated row on printer cards with quick-run buttons
- Toast notification when triggering scripts from settings/sidebar
Closes#176
- Add trimesh and matplotlib dependencies for software-based 3D rendering
- Create stl_thumbnail service with generate_stl_thumbnail() function
- Handle mesh simplification for large files (>100k vertices)
- Auto-generate thumbnails during STL file upload and ZIP extraction
- Add POST /library/files/{id}/regenerate-thumbnail endpoint
- Add POST /library/generate-stl-thumbnails batch endpoint
- Add "Generate Thumbnails" button to file manager toolbar
- Add "Regenerate Thumbnail" option to file context menu
- Add unit and integration tests for new functionality

- 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
Model-based queue assignment:
- Extract printer_model from sliced 3MF files during upload
- Display sliced-for model in archive view
- New queue mode: assign to "Any [Model]" instead of specific printer
- Scheduler auto-assigns to first idle printer of matching model
- Filament validation: only assign to printers with required filament types loaded
- Waiting reason display shows why jobs are waiting (e.g., "Waiting for filament: Printer1 (needs PLA)")
- "Waiting" status badge (purple) distinguishes from regular "Pending"
Queue notifications (7 new events):
- Job Added: When a job is added to queue
- Job Assigned: When a model-based job is assigned to a printer
- Job Started: When a queue job starts printing
- Job Waiting: When a job is waiting for filament (enabled by default)
- Job Skipped: When a job is skipped due to previous failure (enabled by default)
- Job Failed: When a job fails to start (enabled by default)
- Queue Complete: When all queued jobs finish
Backend changes:
- New columns: print_queue.target_model, print_queue.required_filament_types, print_queue.waiting_reason
- New columns: notification_providers.on_queue_job_* (7 event triggers)
- Notification templates for all queue events
- Scheduler validates filament compatibility before model-based assignment
- Queue API extracts filament types from 3MF when adding model-based items
- Local backup/restore includes queue notification settings
Frontend changes:
- TypeScript interfaces updated for new fields
- Queue page shows waiting reason and "Waiting" badge
- Notification settings includes "Print Queue" section with 7 toggles
Closes#162
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
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
- 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
- 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
- Add USB camera type to external camera service
- Auto-detect available V4L2 devices on Linux
- New API endpoint: GET /api/v1/printers/usb-cameras
- Use ffmpeg for USB camera capture and streaming
- Add "USB Camera (V4L2)" option in Settings UI
- Debounce camera URL input to avoid saving on every keystroke
Closes#143
Automatically detect if objects are on the build plate before printing
and pause the print immediately if detected.
Features:
- Per-printer toggle to enable/disable plate detection
- Multi-reference calibration: store up to 5 reference images per printer
for different plate types (textured, smooth, high-temp, etc.)
- Automatic print pause when objects detected at print start
- Push notification and WebSocket alert when print is paused
- ROI (Region of Interest) calibration UI with sliders to adjust
detection area
- Reference management: view thumbnails, add labels, delete references
- Works with both built-in and external cameras
- Uses buffered camera frames when stream is active (no blocking)
- Split button UI: main button opens modal, chevron toggles on/off
- Green visual indicator when plate detection is enabled
- Included in backup/restore
The on_print_progress notification method existed but was never called.
Added milestone tracking in on_printer_status_change that:
- Tracks last notified milestone per printer
- Detects when progress crosses 25%, 50%, 75% thresholds
- Sends notification via notification_service.on_print_progress()
- Resets tracking when progress drops below 5% (new print)
Closes#157
Printers without an SD card store files in the root folder `/` instead of
`/cache`. Added root folder to search paths in both main.py and bambu_ftp.py
so 3MF files can be found regardless of storage configuration.
Closes#146
