A PUT /settings with null for a number setting stored the literal
"None". From then on int()/float() raised inside the response builder,
and every settings read returned 503 until the row was fixed by hand.
Explicit null for any boolean or numeric setting is now refused with a
422 that names the keys, and nothing in that request is saved. A numeric
row that does not parse reads back as its default with a warning, so an
install that already stored one recovers. The typed-key lists moved to
module constants so the save check and the read path share them.
Bed levelling, flow calibration, and nozzle-offset calibration were on/off
only, so the sole way to run bed levelling was to force a full level before
every print. Bambu Studio has always offered a third "Auto" state that lets
the printer skip the calibration when it was done recently -- the state most
users actually want. Make these three options tri-state (off/on/auto),
defaulting to auto, and leave vibration/layer-inspect/timelapse as on/off
(Bambu Studio exposes no auto for those).
Wire encoding follows Bambu Studio's source exactly: each option sends a JSON
bool (true only for "on") plus a companion int -- off=0, on=1, auto=2. The
bool fields stay booleans (the #1478 H2S regression); only the companion int
widened from {0,1} to {0,1,2}. #1721's observation that stage 8/39 stays
queued when sending 2 is the auto contract (queued, skipped at runtime if
recent), not a broken "off".
- schemas: TriState = Literal[off/on/auto] with a BeforeValidator coercing
legacy bool / 0-1 / true-false so old clients and un-migrated rows validate
- model + migration: boolean columns -> String; SQLite via column affinity +
data backfill, PostgreSQL via ALTER COLUMN TYPE guarded on information_schema
(verified on both dialects); settings rows normalised true/false -> on/off
- MQTT: start_print takes the tri-state strings and emits the paired bool+int
- Virtual Printer: reconstructs the slicer's auto/on/off from the int companion
(auto_bed_leveling / extrude_cali_flag) in both capture paths
- frontend: CalibrationMode type; off/auto/on segmented controls in the print
dialog, queue bulk-edit, and Settings -> Workflow; calibrationMode_* strings
in all 11 locales
Reporter wanted to slice via the Bambu Studio sidecar but open files
locally in OrcaSlicer. preferred_slicer drove both the in-app
SliceModal sidecar selection AND the desktop "Open in Slicer" URI
handoff, so picking one forced the other.
New open_in_slicer setting (str | None) drives only the desktop URI;
null inherits from preferred_slicer so existing installs behave
identically. Storage in the existing app_settings key/value table;
GET normalises the "None" string back to null mirroring the
default_printer_id convention.
Frontend: Settings -> Slicer card adds a second dropdown ("Open in
Slicer" with "Same as API slicer" / Bambu Studio / OrcaSlicer);
ArchivesPage, MakerworldPage, ModelViewerModal switch desktop-URI
call sites to open_in_slicer ?? preferred_slicer. MakerworldPage's
"Slice in {{slicer}}" label additionally branches on useSlicerApi
so the label matches what the button actually dispatches.
When adding a print to the queue for multiple printers, users can now
enable "Stagger printer starts" to avoid power spikes from simultaneous
bed heating. Configurable group size and interval — first group starts
immediately (ASAP) or at scheduled time, subsequent groups get offset
scheduled_time values. No backend queue/scheduler changes — leverages
existing scheduled_time field.
Also adds a dedicated Queue tab in Settings (stagger defaults + auto-
drying moved from Filament tab), i18n keys for all 7 locales, frontend
and backend tests.
* feat(queue): show spool grams left in filament slot mapping
* Bumped version
* Add SpoolBuddy AMS slot config, external slots, and dashboard redesign
- AMS page: external spool slots (Ext/Ext-L/Ext-R), click-to-configure
modal on all slots, temperature/humidity threshold-colored indicators,
nozzle L/R badges for dual-nozzle printers, compact AMS-HT layout
- Dashboard: two-column layout with device status + printers list (left)
and current spool card (right), state-colored scale/NFC icons, dashed
border card styling
- Daemon: suppress redundant scale reports (±2g threshold + stability
state change detection) to prevent weight display bouncing
- TopBar: auto-select online printers only, SpoolBuddy logo
* Fix SpoolBuddy daemon crash when read_tag module is missing
NFCReader.__init__ imported read_tag and instantiated PN5180() outside
the try/except block, so a missing module crashed the entire daemon.
Moved the import inside the existing try/except so the daemon gracefully
skips NFC polling — matching the scale reader's existing behavior.
* Fix SpoolBuddy daemon failing to import hardware drivers
The daemon imports read_tag and scale_diag as bare modules, but they
live in spoolbuddy/scripts/ which isn't on sys.path when systemd runs
the daemon. Added scripts/ to sys.path at startup, resolved relative
to the module file. Also moved the read_tag import inside NFCReader's
try/except (was crashing the daemon instead of skipping gracefully)
and demoted hardware-not-available messages from ERROR to INFO.
* Increase scale moving average window to reduce weight bouncing
5 samples at 100ms (500ms window) wasn't enough to smooth NAU7802 ADC
noise — the averaged value still varied by >2g between 1s report
intervals, and the stability state kept flipping, triggering a report
every cycle. Increased to 20 samples (2s window) so noise is smoothed
before reaching the reporting layer.
* Remove stability flipping as scale report trigger
When ADC noise kept the spread hovering around the 2g stability
threshold, the stable flag toggled every cycle, forcing a report with
a slightly different weight each time. Now only actual weight changes
of >=2g trigger reports. The stable flag is still included in each
report for consumers that need it.
* Fix formatting of option elements in FilamentMapping
* Make low stock threshold editable
* Add new filter for low spools
* Update bug report template to require additional fields
* Added toast for invalid imputs with locales, updated inputb field restrictions
* Minor Spoolbuddy frontend improvements
* Updated test_backend.sh
* Updated Spoolbuddy install script to strip down Raspbian
* Updated Spoolbuddy install script
* Add API key auth support to /auth/me for SpoolBuddy kiosk
When Bambuddy auth is enabled, the SpoolBuddy kiosk gets redirected to
the login page because ProtectedRoute requires a user from GET /auth/me,
which only handled JWT tokens. The kiosk daemon already has an API key
but couldn't use it to satisfy the frontend auth check.
- Backend: /auth/me now accepts API keys (Bearer bb_xxx or X-API-Key)
and returns a synthetic admin UserResponse with all permissions
- Frontend: AuthContext reads ?token= from URL on first load, stores in
localStorage, and strips from URL (prevents history/referrer leakage)
- Install script: kiosk URL now includes ?token=${API_KEY}
- Tests: 3 new integration tests (Bearer API key, X-API-Key header,
invalid key rejection)
* SpoolBuddy touch-friendly UI overhaul for 1024x600 kiosk display
Enlarge all interactive elements across 9 SpoolBuddy components to meet
44px minimum tap targets on the RPi touchscreen. Increase nav icons
(20→24px), labels (10→12px), bar heights, section headers, printer
buttons, spool visualizations, fill bars, and status indicators.
Compact the dashboard stats bar and remove the printers card. Add
fullScreen prop to ConfigureAmsSlotModal with two-column layout
(filament list left, K-profile + color right) to eliminate scrolling.
* Minor changes, CSS fixes
* Refactor usageFilter state to remove 'lowstock' option for clarity
* Move var saving to API, add test coverage
* fix: threshold validation and cleanup
* Change test input from '150' to '0'
