Per-printer camera rotation (0°/90°/180°/270°) for cameras mounted
in portrait or upside-down. CSS rotation for live views, Pillow
rotation for notification snapshots. Setting visible in external
camera config when enabled.
Queue auto-drying: scheduler automatically starts drying on idle printers
with scheduled queue prints when AMS humidity exceeds the configured
threshold. Uses conservative parameters (lowest temp, longest duration)
for mixed filaments. Drying stops when humidity drops below threshold
(30-minute minimum prevents oscillation), when scheduled items are
removed, or when the feature is disabled. Optional "block queue" mode
delays the next print until drying completes.
Configurable presets: temperature and duration per filament type,
editable in Settings → Print Queue, used by both manual drying popover
and queue auto-drying. Separate presets for AMS 2 Pro (n3f) and AMS-HT
(n3s) reflecting different heating capabilities.
PSU detection: drying button disabled with tooltip when dry_sf_reason
indicates insufficient power. Parses drying status bits and dry_sf_reason
from AMS info hex string via MQTT.
Backend: print_scheduler.py (+316 lines), bambu_mqtt.py, printer_manager,
schemas, settings route. Frontend: PrintersPage drying presets prop,
SettingsPage drying config UI, i18n (7 locales). Tests: 27 new tests in
test_scheduler_auto_drying.py covering conservative params, presets,
state sync, stop logic, minimum drying time, and auto-stop regressions.
Start, monitor, and stop drying sessions for AMS 2 Pro (n3f) and
AMS-HT (n3s) directly from the Printers page. Flame icon in AMS card
header opens a popover with filament-based temperature/duration presets
from BambuStudio. Live countdown status bar shows time remaining.
Backend: cache module_type from MQTT get_version, expose dry_time and
module_type in both WebSocket and REST paths, add supports_drying()
with firmware gating, add server-side guard on start_drying endpoint.
Frontend: drying button, popover with filament select + temp/duration
sliders, status bar, start/stop mutations. i18n for all 7 locales.
Supported: X1/X1C (fw 01.09+), P1P/P1S (fw 01.08+), H2D (fw 01.02.30+),
H2D Pro, X1E. Not supported: P2S, A1, A1 Mini, H2S, H2C.
home_flag bit 18 is set on all printers regardless of hardware,
causing the ethernet badge to appear on WiFi-only models (A1, P1P,
etc.). The previous fix removed the feature entirely, so ethernet
printers lost their badge too.
Now only trusts bit 18 on models with an ethernet port (X1C, X1E,
P1S, P2S, H2D, H2D Pro, H2C, H2S). WiFi-only models always show
the WiFi signal badge.
home_flag bit 18 was incorrectly interpreted as "wired/ethernet
connection", causing the ethernet badge to always show — even on
printers without an ethernet port (e.g. A1, P1S). This hid the
WiFi signal indicator entirely.
Removed the wired_network field and ethernet badge UI. The WiFi
signal badge now shows correctly whenever the printer reports
signal strength.

Parse home_flag bit 18 (0x00040000) from MQTT to detect ethernet
connections. When set, the printer card shows a green "Ethernet"
badge with a cable icon instead of WiFi signal strength in dBm.
The printer info modal also displays "Ethernet" instead of WiFi
signal details.
Parse the MQTT "fun" field bit 0x20000000 to detect whether connected
printers have Developer LAN Mode enabled. Show a persistent orange
warning banner when any printer lacks it, since newer firmware silently
rejects MQTT write commands without developer mode.
- Parse fun field into developer_mode on PrinterState
- Add /printers/developer-mode-warnings lightweight polling endpoint
- Include developer_mode in printer status API and support bundle
- Orange banner with affected printer names and wiki link
- Translations for all 6 locales (en, de, fr, it, ja, pt-BR)
- 7 backend + 4 frontend tests
After clicking "Clear Plate & Start Next", refreshing the page showed
the button again because the frontend determined the state purely from
the printer's FINISH/FAILED status. The backend already tracked a
plate_cleared flag in memory but never exposed it to the frontend.
- Add plate_cleared field to PrinterStatus schema and API response
- Pass plateCleared prop to PrinterQueueWidget
- Skip clear plate UI when plate is already acknowledged
- Add 2 tests for plateCleared=true behavior
Backend:
- Add dual external spool support for H2D (vt_tray as list: Ext-L/Ext-R)
- Add cloud filament ID map endpoint (/cloud/filament-id-map)
- Fix RFID spool data erased by periodic AMS updates (skip tag matcher
for RFID-tagged trays)
- Fix AMS slot config overwrites RFID spool state
- Fix K-profile selection corrupts existing profiles on X1C/P1S
- Resolve K-profiles filament name via cloud filament ID map
- Update print scheduler and usage tracker for dual external spools
Frontend:
- Add printer model filtering to ConfigureAmsSlotModal (cloud/local/builtin
presets filtered by @BBL model suffix and compatible_printers)
- Add pre-population for configured slots (preset, color, K-profile)
- Add K-Profiles view with accurate filament name resolution
- Internationalize all ConfigureAmsSlotModal strings (en/de/fr/it/ja — 21 keys)
- Add 5 new ConfigureAmsSlotModal tests (model filtering, pre-selection,
color pre-population, i18n)
- Update PrintersPage for dual external spool rendering
Docs:
- Update CHANGELOG, README, website features, and wiki AMS docs
- Show all 6 nozzles including mounted: backend includes all nozzle_info
entries (removes id >= 2 filter), frontend filters to non-empty
- Translate nozzle type codes to full names: HS→Hardened Steel, 00/01/05
mapped to Stainless Steel/Hardened Steel/Tungsten Carbide
- Add flow type to hover card: HH→High Flow, HS→Standard
- Show filament material type in hover card (PLA, PETG etc.) from MQTT
tray_type/filament_type field
- Add filament_type to NozzleRackSlot schema (backend + frontend)
- Add translations (en, de, ja, it): nozzleTungstenCarbide, nozzleFlow,
nozzleHighFlow, nozzleStandardFlow
Capture 4 additional fields from MQTT nozzle data (max_temp, serial_number,
filament_color, filament_id) and surface them through REST/WebSocket APIs.
Add per-slot hover popover to the NozzleRackCard showing all metrics, filament
color backgrounds on slots, and i18n labels in all 4 locales.
The H2C printer has a tool-changer with a 6-nozzle rack, but
device.nozzle.info entries beyond index 1 were being dropped due to a
hardcoded 2-nozzle limit. This adds full nozzle rack storage, API
exposure, and a frontend card showing all dock positions.
Users with local DNS can now add printers using hostnames like
printer.local or my-printer.home.lan. Updated backend schema
validation, database column width, frontend form patterns/placeholders,
and i18n labels across all locales. Added integration tests for
hostname and FQDN creation plus invalid hostname rejection.
- 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

stitches to MP4 video on print completion
Backend changes:

fields to Printer model with database migration
- New external_camera.py service: MJPEG/RTSP/snapshot frame capture,
connection testing, MJPEG stream generation
- New layer_timelapse.py service: TimelapseSession management,
layer-by-layer frame capture, ffmpeg video stitching
- Add on_layer_change callback to MQTT client and printer manager
- Update camera routes with external camera streaming and tracking
- Update print lifecycle hooks for timelapse start/stitch/cancel
- Add external camera fields to backup/restore
- Rate limiting for external camera streams (prevents browser freeze)
Frontend changes:
- Add external camera configuration UI in Settings > Camera
- Per-printer enable toggle, URL input, type selector, test button
- Toast notification on save
Closes#143
