- Skip Objects Modal:
- Object ID markers overlaid on preview image (grid layout)
- Large prominent ID badges to match printer display
- Info banner explaining to match IDs with printer screen
- Layer warning when skip unavailable (layer <= 1)
- Red badge on button showing skipped count
- Preview image now shown when paused (not just running)
- Close with ESC key or click outside modal
- Full light/dark theme support
- Backend:
- Extract object positions from 3MF (include_positions=True)
- API returns x/y coordinates for objects (when available)
- Parse s_obj from printer MQTT for skipped state persistence
- Cover URL available in PAUSE/PAUSED states
- Tests:
- Added test for objects with position data
- Fix runtime_seconds never incrementing during prints
- Bug: first timestamp was set but never committed (updated_count was 0)
- Add needs_commit flag to ensure timestamp is saved on first iteration
Implement comprehensive theme customization with independent settings for
dark and light modes:
- Style layer: Classic (clean shadows), Glow (accent-colored glow effects),
Vibrant (dramatic deep shadows)
- Background layer: Neutral, Warm, Cool (light mode); plus OLED, Slate,
Forest (dark mode only)
- Accent colors: Green, Teal, Blue, Orange, Purple, Red
All combinations work independently (e.g., Glow + Forest + Teal). Settings
sync across devices via database and show toast confirmations on change.
Backend:
- Add 6 new settings fields (dark_style, dark_background, dark_accent,
light_style, light_background, light_accent)
- Add integration test for theme settings API
Frontend:
- Refactor index.css with 3-layer CSS variable system
- Update ThemeContext for dual-mode theme management
- Add Appearance section to Settings page with 6 dropdowns
- Update components for new ThemeContext API
- Virtual printer appears in Bambu Studio/Orca Slicer via SSDP discovery
- Secure TLS/MQTT communication with auto-generated certificates
- Queue mode (pending uploads) or auto-start mode
- Configurable access code for authentication
- Docker support with network_mode: host and certificate persistence
- Fix backup/restore for virtual printer settings (auto-save no longer overwrites)
- Add fuzzy color matching for filament comparison
Colors within RGB threshold of 40 are considered a match, fixing
cases where 3MF and printer report slightly different hex values
for the same filament color (e.g., beige #F5F5DC vs #FCECD6)
- Add POST /printers/{id}/refresh-status endpoint
Sends MQTT pushall command to request fresh AMS data from printer
- Improve Re-read button in filament check section
- Now triggers backend refresh before refetching status
- More prominent styling with text label and border
- 500ms delay after pushall to allow printer to respond
- Add AMS slot labels to matched filament display
Shows location like "PLA (AMS-B Slot 3)" instead of just "PLA"
- Add color hex tooltips on filament color circles
- Features:
- Tasmota device discovery: Auto-detect network and scan for Tasmota devices
in Add Smart Plug modal. Supports devices with/without authentication.
- Switchbar: Quick access widget in sidebar footer for controlling smart plugs
from anywhere in the app. Shows real-time status and power consumption.
- AMS Filament Preview:
- Add GET /archives/{id}/filament-requirements endpoint to extract
filament data from archived 3MF slice_info.config
- Show filament comparison in reprint modal when printer is selected
- Compare both filament type AND color with visual indicators:
- Green checkmark: Type and color match
- Yellow warning: Same type, different color
- Orange warning: Different type or empty slot
- Handle AMS-HT units (id >= 128) and virtual tray (slot 254)
- Normalize color formats between API (RRGGBBAA) and 3MF (#RRGGBB)
- File Type Badge:
- Archive cards show GCODE (green) or SOURCE (orange) badge

- Add Edit button to TimelapseViewer
- Fix browser caching with timestamp query parameter
- Change default timelapse playback speed from 2x to 1x
- Detect Docker environment automatically via /.dockerenv and cgroup
- Show subnet input field in Add Printer dialog when running in Docker
- Scan IP range for Bambu printer ports (8883 MQTT, 990 FTPS)
- Query SSDP to get printer name/serial/model from discovered IPs
- Map raw SSDP model codes to friendly names (BL-P001→X1C, O1D→H2D)
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.

- Add getStatusDisplay() helper in frontend to format status nicely
- Add get_derived_status_name() in backend to compute status from:
- stg_cur calibration stages (bed leveling, vibration comp, etc.)
- Temperature data when stg_cur unavailable (heating heatbed/nozzle)
- Include stg_cur and stg_cur_name in WebSocket broadcasts
- Update broadcast status key to detect heating phase changes
Printer cards now show: "Heating heatbed", "Heating nozzle", "Preparing",
"Auto bed leveling", "Cleaning nozzle tip", and 60+ other stage names
instead of just "Printing" or "Idle".
Root cause: When a print completed with the camera stream popup open,
spawning a second ffmpeg process for finish photo capture caused a
conflict that froze the browser tab and video window.
Solution: Buffer the last frame from active camera streams. When
capturing finish photo, use the buffered frame if a stream is active
instead of spawning a new ffmpeg process.
Backend changes:
- camera.py: Added _last_frames buffer and get_buffered_frame() helper
- main.py: Photo capture uses buffered frame when stream is active
- main.py: Moved slow operations to background tasks (energy calc,
photo capture, smart plug, notifications, maintenance)
- archive.py: Fixed sync file write blocking event loop (asyncio.to_thread)
- printers.py: Added debug endpoint to simulate print completion
Frontend changes:
- useWebSocket.ts: Throttled printer status updates (100ms) to prevent
UI overload from rapid WebSocket messages
- useWebSocket.ts: Debounced archive invalidations (3s) to prevent
cascade of re-renders on print completion
- useWebSocket.test.ts: Updated tests for throttled/debounced handlers

Backend (backend/app/api/routes/archives.py):
- Added filament_colors extraction from slice_info.config in 3MF files
- Maps filament IDs (1-based) to tool numbers (0-based)
Frontend (frontend/src/components/GcodeViewer.tsx):
1. Multi-color support: Pass extrusionColor as array of CSS color strings for multi-color prints
2. Bambu T-command filtering: Filter out special Bambu commands (T255, T1000, T1001, T65535, T65279) that corrupt tool state
3. Initial tool: Prepend T0 to ensure initial tool is set correctly
4. Disable gradient: Set disableGradient: true for multi-color to preserve actual filament colors (the gradient was turning black into gray/white)
5. Disable topLayerColor: Don't set topLayerColor for multi-color (it overrides per-tool colors)
Key fixes for Bambu G-code compatibility:
- Bambu uses special T commands (T1000, T65535, etc.) that aren't real tool changes
- The gcode-preview library's brightness gradient was modifying colors based on layer index
Commit message suggestion:
Add multi-color filament support to G-code viewer
- Extract filament colors from 3MF slice_info.config
- Pass color array to gcode-preview for tool-based coloring
- Filter Bambu special T commands (T1000, T65535, etc.)
- Disable gradient to preserve actual filament colors
- Replace manual error database with 853 codes from ha-bambulab
(Source: https://github.com/greghesp/ha-bambulab)
- Filter out unknown HMS error codes from display
(Printers sometimes send duplicate/undocumented codes for same error)
- Update HMS badge count to only show known errors
- Export filterKnownHMSErrors helper for reuse across components
- The failure analysis service was only querying status == "failed"
- Changed all queries to include both failed AND aborted: status.in_(["failed", "aborted"])
- File: backend/app/services/failure_analysis.py
Issue 2: Cannot clear failed flag in edit mode
- Added status field to ArchiveUpdate schema (backend)
- Added status to API client type (frontend)
- Added status dropdown to EditArchiveModal with options: Completed, Failed, Cancelled, Printing
- When status changes to "completed", failure_reason is automatically cleared
- File changes:
- backend/app/schemas/archive.py - added status field
- frontend/src/api/client.ts - added status to updateArchive type
- frontend/src/components/EditArchiveModal.tsx - added status dropdown
Test Summary:
- Build tests: 3 passed (image build, backend imports, static files)
- Backend unit tests: 378 passed (9 docker tests excluded)
- Frontend unit tests: 137 passed
- Integration tests: 9 passed (health, API endpoints, persistence, WebSocket)
Changes made to fix the Docker test suite:
1. Added curl to the production Dockerfile for integration tests
2. Removed deprecated version attribute from docker-compose.test.yml
3. Added --pull flag to all build commands to ensure fresh images
4. Added explicit build step before starting integration container
5. Fixed WebSocket test to accept 200 as a valid response
6. Excluded docker-marked tests from backend unit test runs (-m "not docker")
- H2D sends timelapse status in ipcam.timelapse field, not xcam.timelapse
- Added parsing for timelapse from ipcam data
- Added test to prevent regression
2. Systemd service updated - /etc/systemd/system/bambuddy.service
- Now runs as claude user instead of root
- Added ExecStartPre commands with + prefix (runs as root) to:
- Create logs and archive directories if missing
- Fix ownership to claude:claude before service starts
The service restarted successfully with the permission fixes running at startup. On the next print with timelapse enabled, both the snapshot and timelapse should be captured automatically.
1. bambu_mqtt.py: Added hms_errors to the completion callback data, which includes the HMS error codes when a print fails
2. archive.py: Updated update_archive_status() to accept an optional failure_reason parameter
3. main.py: Added auto-detection of failure reasons:
- status == "aborted" → failure_reason = "User cancelled"
- status == "failed" with HMS errors → maps module codes to reasons:
- Module 0x07 (Filament) → "Filament runout"
- Module 0x0C (Motion Controller) → "Layer shift"
- Module 0x05 (Nozzle) → "Clogged nozzle"
Frontend changes:
1. ArchivesPage.tsx:
- Badge now shows "cancelled" for aborted prints, "failed" for failed prints
- "Failed Prints" collection and "Hide Failed" filter now include both failed and aborted statuses
2. EditArchiveModal.tsx: Failure reason field now shows for both failed and aborted prints
New tests added:
- test_hms_errors_included_in_failed_completion_callback
- test_aborted_status_when_cancelled
The HMS error module mapping is basic and can be expanded as you observe more failure types. The actual Bambu HMS error codes are documented in their wiki - we can add
more mappings as needed.
