- 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
- Add utils/slicer.ts with OS detection for protocol handler
- Windows: bambustudio://, macOS/Linux: bambustudioopen://
- Update all usages in ArchivesPage.tsx and ModelViewerModal.tsx
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
0.1.6b2
* New Features
- Add Virtual Printer feature - SSDP discovery, TLS/MQTT, queue/auto-start modes, Docker support
- Emulates a Bambu Lab printer on your network - Bambuddy pretends to be a real printer
- Auto-discovery - appears automatically in Bambu Studio/Orca Slicer via SSDP protocol
- Send prints from slicer - slice and send directly to Bambuddy without a physical printer connected
- Two modes:
- Queue mode - prints go to "Pending Uploads" for manual review/scheduling
- Auto-start mode - prints immediately start on your default printer
- Secure communication - TLS 1.3 encrypted MQTT + FTPS with auto-generated certificates
- Access code authentication - 8-digit code like real Bambu printers
- Docker compatible - requires network_mode: host and volume mount for certificate persistence
- All archive page filters are now persistent
* Bugfixes
- Fix AMS filament matching in reprint modal
- Archive card: fixed cache bug with wrong cover image
- Minor bugfixes in queueing module (re-queue modal fix)
* Housekeeping
- Added frontend/backend tests for archive card AMS mapping
- 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

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.

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- 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".
Release Notes for 0.1.5
Highlights
This release focuses on stability improvements and bug fixes, with major fixes for browser freezing and UI responsiveness issues.
Bug Fixes
- Browser freeze on print completion - Fixed a critical issue where the browser would freeze when a print completed with the camera stream open. The fix uses buffered camera frames instead of spawning duplicate ffmpeg processes.
- Printer status "timelapse" effect - Fixed an issue where navigating to the printer page after a print completed showed metrics animating slowly from mid-print values to the final state. Printer status messages now bypass the throttled queue for immediate updates.
- Timelapse auto-download - Complete rewrite with retry mechanism and support for multiple storage paths.
- Timelapse detection for H2D - Fixed detection using the correct ipcam.timelapse field instead of xcam.timelapse.
- Reprint from archive - Fixed bug where the print button sent the slicer source file instead of the sliced gcode.
- Import shadowing bugs - Fixed ArchiveService import shadowing causing "cannot access local variable" errors.
New Features
- Failure reason detection - Automatically detects failure reasons from HMS errors (filament runout, layer shift, clogged nozzle)
- Hide failed prints filter - Toggle to hide failed/aborted prints with localStorage persistence
- Docker test suite - Comprehensive tests for build, backend, frontend, and integration
- Pre-commit hooks - Ruff linter and formatter for code quality
- Code quality tests - Static analysis to catch import shadowing bugs automatically
Changes
- Timelapse viewer default playback speed changed from 0.5x to 2x
- Archive badges now show "cancelled" for aborted prints
- WebSocket throttle reduced to 100ms for smoother updates
- Added ffmpeg to Docker image
