- 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.
prints (not just completed), matching get_printer_total_hours behavior
- Add option to keep or delete archives when deleting a printer
- Custom maintenance types no longer auto-assign to all printers
- Add UI to manually assign/remove custom maintenance types per printer
- Add backend endpoints for assigning types to printers and removing items
- Exclude static/assets from large file pre-commit check
- 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".
When navigating to the printer page after a print completed, status
metrics would animate slowly from mid-print values to final state.
Root cause: The message queue processed messages one at a time with 16ms
delays. If 50+ status updates queued during a print, they took 800ms+ to
process, causing multiple throttle windows and the visual "timelapse".
Solution: Handle printer_status messages directly without queueing.
They're already throttled (100ms) so don't need queue rate limiting.
Other message types still use the queue.
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
When a print completes, multiple WebSocket messages are sent rapidly
(print_complete, archive_updated, etc.). Each was immediately invalidating
the archives query, causing a cascade of rapid re-renders that crashed
the browser tab.
Added debounced query invalidation to useWebSocket.ts:
- Multiple invalidation requests within 100ms are coalesced into one
- Uses requestAnimationFrame to avoid blocking the main thread
- Properly cleans up timeouts on unmount
- Cache connected state in ref to prevent flicker when status
briefly becomes undefined during query refetches
- Use cached value for shouldHide calculation instead of raw status
- 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
- Add ~80 HMS error code descriptions covering:
- 0300 series: temperature, fan, motor, force sensor, build plate errors
- 0500 series: storage, network, module communication, camera errors
- 0700 series: AMS communication, filament, hotend matching errors
- 0C00 series: toolhead camera, lidar, AI detection errors
- 1200 series: external spool errors
- Fix 0500_0400_0002_0043 description (toolhead camera dirty, not file system)
- Always link to HMS home page (wiki.bambulab.com/en/hms/home) instead of
specific error pages that may not exist

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.
- frontend/src/components/TimelapseViewer.tsx:17 - Changed from 0.5 to 2
2. Archive page: hide failed prints filter with persistence
- Added hideFailed state initialized from localStorage.getItem('archiveHideFailed')
- Added localStorage persistence via useEffect
- Added "Hide Failed" toggle button (red styling when active) next to the Favorites button
- Filter is automatically bypassed when viewing the "Failed Prints" collection
- "Reset" button also clears this filter
The filter state persists across page refreshes and browser sessions via localStorage.
Changes to ToastContext.tsx:
- Added 'loading' toast type with a spinning Loader2 icon
- Added showPersistentToast(id, message, type) function for toasts that don't auto-dismiss
- Exposed dismissToast(id) function to allow programmatic dismissal
- Added green-themed styling for loading toasts
Changes to SettingsPage.tsx:
- When exporting a backup that includes archives, shows a persistent "Preparing backup..." toast with spinner
- The toast is automatically dismissed when the download starts or if an error occurs
- For non-archive backups (which are fast), no loading toast is shown
The user will now see clear feedback when creating a backup with print archives - a toast with a spinner appears immediately after clicking export and stays visible
until the download dialog appears.
