The per-printer InlineMappingEditor showed filaments from both nozzles
on H2D printers. The single-printer FilamentMapping dropdown was fixed
in 29e9593 but the multi-printer code path was missed. Added nozzle_id
filtering to both auto-match logic and dropdown options via shared
autoMatchFilament() and filterFilamentsByNozzle() functions in
amsHelpers.ts, with 10 regression tests.
Two lazy-load bugs caused greenlet_spawn errors in the RFID auto-assign
flow:
1. create_spool_from_tray set spool.k_profiles=[] AFTER db.flush(),
but assigning to a relationship on a persistent object triggers a
lazy load (SQLAlchemy loads the current collection before replacing).
Moved initialization to BEFORE db.add().
2. spool.assignments was never initialized or eagerly loaded, so
db.add(SpoolAssignment) triggered a back_populates lazy load
outside the async greenlet. Added assignments=[] in create and
selectinload(Spool.assignments) in get_spool_by_tag.
Also added exc_info=True to error handlers for full tracebacks, and
19 new tests including greenlet regression tests that reproduce the
exact failure.
The install script hardcoded origin/main, so beta testers told to
install from a dev branch silently got the stable release instead.
Add a --branch CLI option and interactive prompt (defaults to main).
Invalid branch names are validated via git ls-remote before any work
is done, showing available branches on failure.
The install script hardcoded origin/main, so beta testers told to
install from a dev branch silently got the stable release instead.
Add a --branch CLI option and interactive prompt (defaults to main).
Fresh installs use git clone --branch, existing installs checkout
and reset to the selected branch.
enum.StrEnum was added in Python 3.11, but the documented minimum is
3.10. Add a compatibility shim in backend/app/core/compat.py that falls
back to (str, Enum) on older versions. Updated all 5 import sites and
lowered pyproject.toml target-version to py310.
Bambu printers only support plain RSA key exchange ciphers
(AES256-GCM-SHA384, AES128-GCM-SHA256), but Python's OpenSSL 3.x
defaults exclude them in favor of forward-secrecy (ECDHE/DHE) only.
Add the RSA ciphers to the client SSL context so the TLS proxy can
connect to the printer's bind port (3002).
Move the toast container from bottom-4 to bottom-20 so toast
notifications and upload progress stack above the bug report bubble
instead of rendering on top of each other.
When the print queue scheduler finds pending items but doesn't start
any, there was no logging to explain why. Added INFO-level summary
after each queue check showing skip reasons (manual_start,
scheduled_future) and busy printer details (state, connected,
plate_cleared). Also added DEBUG-level logging in _is_printer_idle()
for the specific condition that failed.

On Windows, process.terminate() on ffmpeg broadcasts CTRL_C_EVENT to
the entire process group, causing uvicorn to shut down. Spawn ffmpeg
with CREATE_NEW_PROCESS_GROUP so cleanup doesn't affect the server.
* Fix AMS slot modal not scrolling to preselected filament
The scroll useEffect fired before the loading spinner was replaced
by the preset list, so the DOM element didn't exist yet. The ref
guard was then set, preventing any retry once buttons appeared.
- Move isLoading computation before the scroll effect and add it
as a dependency so the effect re-runs when loading completes
- Gate scroll on !isLoading so it only runs when buttons exist
- Only mark scrolledToRef after the element is actually found
- Use requestAnimationFrame to scroll after browser layout
- Use block:'center' so the selected item is clearly visible
Preselect filament for printer-configured AMS slots
When an AMS slot was configured directly on the printer (no
savedPresetId), the modal didn't preselect the filament even though
it was in the list. Add a third fallback that matches trayInfoIdx
against the full filteredPresets list (cloud and builtin sources).
* Restore scrolledToRef lost during merge
The useRef import, scrolledToRef declaration, and its reset were
dropped during the 0.2.2b1 merge, causing a ReferenceError in the
scroll-to-preselected-filament effect.
* Fix preset scroll loop and wire up useEffect scroll logic
- Remove inline ref callbacks with scrollIntoView on both preset
button lists (fullscreen + standard) to stop the infinite scroll
loop on Windows
- Add data-preset-id attribute so the existing useEffect/querySelector
scroll logic can actually find the elements
- Replace filteredPresets dependency with builtinFilaments in the
selection useEffect to prevent search keystrokes from overriding
manual preset selection
* Adjust scroll behavior in ConfigureAmsSlotModal

Floating bug report button submits issues via bambuddy.cool relay (no GitHub
token needed locally). Collects 30s debug logs with printer push_all, sanitizes
all sensitive data, uploads logs as files to GitHub. Screenshot upload/paste/drag
with JPEG compression. Translated into all 7 languages. Includes 21 tests.
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.
The firmware check only mapped display names (e.g., "H2D Pro") to
API keys but not raw SSDP device codes (e.g., "O1E", "O2D"). If a
printer's model was stored as the raw SSDP code, the firmware check
either failed or matched the wrong model — H2D Pro matched against
H2D firmware, showing a false update-available badge.
Add all known SSDP device codes to MODEL_TO_API_KEY so firmware
versions resolve correctly regardless of how the model was stored.
The previous fix only filtered status codes (< 0x4000) from the
print_error field. Firmware can also send the same false positive
through the hms array in MQTT, which had no such filter. Apply the
same < 0x4000 check to the HMS parser so status/phase indicators
are skipped regardless of which MQTT field carries them.
- Extract shared detectSystemDateFormat() helper to eliminate
duplicated system locale detection in date.ts
- Derive SUPPORTED_CURRENCIES from CURRENCY_SYMBOLS map instead
of maintaining a duplicate hardcoded list
- Consolidate redundant time-parsing regex paths into one
- Use applyTimeFormat() consistently in formatETA()
- Add exhaustive switch default for type safety
The isSlicedFile() check only matched .gcode or .gcode.3mf extensions,
so archives from .3mf prints (the standard Bambu slicer output) showed
a "SOURCE" badge instead of "GCODE". Since .3mf can be either sliced or
a raw CAD export, now checks the archive's total_layers and
print_time_seconds metadata to distinguish them. Also passes the
original filename when creating archives from file manager prints.
FTP upload: reduce chunk size from 1MB to 64KB for smooth progress bar
updates (~1s intervals instead of 20+ second gaps). Skip voidresp() for
all printer models — H2D delays the 226 response by 30+ seconds after
data transfer, causing a hang at 100%. Add transfer speed and TLS
handshake timing to logs for diagnosing slow connections.
Print/Schedule modal: widen from max-w-lg (512px) to max-w-2xl (672px)
to accommodate long filament profile names like "PLA Support for PETG
PETG Basic @Bambu Lab H2D 0.4 nozzle".
Profiles like "PLA Support for PETG PETG Basic @Bambu Lab H2D" have
filament_type PETG, but both the frontend and backend name parsers
found "PLA" first (iterating material types in order). The MQTT command
sent tray_type=PLA and tray_info_idx=GFL99 (PLA generic), so the
slicer displayed PLA instead of PETG.
- Frontend parsePresetName(): detect "X Support for Y" pattern, extract
material after "Support for"
- Frontend ConfigureAmsSlotModal: prefer corrected parsed material over
stored localPreset.filament_type for tray_type, tray_info_idx, and
temperature fallback
- Backend _parse_material_from_name(): same "Support for" handling for
future profile imports
- Backend assign_spool: prioritize spool.material over lp.filament_type
for generic filament ID lookup
The slicer_binary_path key was left in the settings table from earlier
slicer integration research but is no longer referenced anywhere in the
codebase. Add a startup migration step that deletes orphaned settings
keys so they don't persist in backups.
Inline callback refs on preset buttons called scrollIntoView on every
re-render, creating a scroll → re-render → scrollIntoView loop on
Windows. Replace with a useEffect + data attribute approach that only
scrolls when the selected preset actually changes.
* Add printer card print flow with drag-drop and reusable LibraryUploadModal
Extract inline upload modal from FileManagerPage into a reusable
LibraryUploadModal component. Add a Print button and drag-drop zone
to printer cards that upload files to the library and open PrintModal
with the printer pre-selected. Only .gcode/.gcode.3mf files are
accepted for printing. PrintModal hides printer selector when a
printer is provided via initialSelectedPrinterIds prop.
* Add printer compatibility check for drag-drop and upload-to-print flows
Validates sliced_for_model from file metadata against the target printer model
before opening the print modal, preventing users from printing with incompatible files.
* Improve FileUploadModal: auto-close on success, inline errors, file validation, and i18n
- Close modal automatically after successful upload instead of showing summary
- Show printer compatibility errors inline in the modal instead of closing
- Add validateFile and accept props to restrict file types for print flow
- Add onFileUploaded error return to prevent modal close on incompatible files
- Internationalize all hardcoded error/warning strings across 6 locales
* Clean up incompatible files from library and fix print button i18n
- Delete uploaded file from library when printer compatibility check fails
in both drag-drop and modal upload flows
- Fix print button tooltip to use existing common.print i18n key
- Fix accept attribute to use .gcode,.3mf for proper browser support
* Add printer information modal accessible from card 3-dot menu
Replace inline IP/serial display at bottom of printer card with a
dedicated "Printer Information" modal opened via the card menu. The
modal shows model, status, state, IP address (copyable), serial number
(copyable), WiFi signal, firmware, developer mode, nozzle count, SD
card, auto-archive, total print hours, location, and added date, along
with the printer image. Includes full i18n support across all 6 locales
and accessibility attributes (role="dialog", aria-modal).
* Extract getPrinterImage and getWifiStrength into shared printer utils

PR #569 introduces drag-drop printing on printer cards with
inline fallback strings for common.uploading, common.uploadFailed,
printers.dropToPrint, and printers.cannotPrint. Add these keys
to all 7 locale files so they render in the correct language.
* 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'

Some firmware sends non-zero print_error values (e.g. 0x03000002 →
0300_0002) during normal printing as status/phase indicators. The
parser treated any non-zero value as a real error, triggering
notifications. All known real errors have codes >= 0x4000 (fatal,
warning, prompt ranges). Now skips print_error values where the
low 16 bits are below 0x4000.
Also fix K-profile greenlet error on auto-created RFID spools by
eagerly setting k_profiles=[] after flush in create_spool_from_tray().
create_spool_from_tray() didn't eagerly load the k_profiles
relationship, so auto_assign_spool() triggered a lazy load in async
context when iterating spool.k_profiles. Set k_profiles=[] on new
spools since they can never have K-profiles yet.
Write NTAG213/215/216 tags for third-party spools via the SpoolBuddy
kiosk UI. New "Write" page with three workflows: existing spool, new
spool creation, and tag replacement. Backend encodes 133-byte OpenTag3D
NDEF payloads (material, color, brand, weight, temp). Daemon writes
page-by-page via PN5180 NTAG WRITE command with read-back verification.
Write commands flow through heartbeat polling with WebSocket status
updates. Includes 39 new tests and translations for all 6 languages.
- Add printer status badges to dashboard left column (green/gray
online/offline dots, compact wrapping pills, overflow-hidden)
- Remove SpoolBuddy inventory page — inventory management belongs
in the main Bambuddy frontend, not the kiosk
- Remove inventory nav item from bottom nav (now 3 tabs)
- Replace "Add to Inventory" navigate with quick-add modal that
creates a basic PLA spool entry via API, with a hint to use
the main Bambuddy UI for full spool details instead
- Redesign settings page with tabbed layout (Device, Display, Scale, Updates)
- Add screen blank timeout: blanks after touch inactivity, tap to wake
- Add CSS brightness filter for HDMI displays (no sysfs on HDMI)
- Add backend `language` field to app settings for server-side persistence
- Sync UI language from backend on kiosk load (separate Chromium instance)
- Top bar clock respects user's time format setting (system/12h/24h)
- Add SpoolBuddy settings translations for all 6 languages (en/de/fr/ja/it/pt-BR)
- Disable Chromium swipe-to-navigate in kiosk install script
- Add `video` group for DSI backlight access
1. Device tab — repo URL unlinked
Replaced the <a> tag with a <span> so the GitHub URL is displayed as plain text (no clickable link in kiosk mode).
2. Display controls — moved to frontend
Root cause: The daemon runs as a system user without Wayland access, and the kiosk uses an HDMI display (no sysfs backlight). Neither wlopm, vcgencmd, nor sysfs writes
can work in this setup.
Fix — frontend-controlled display in SpoolBuddyLayout.tsx:
- Brightness: CSS filter: brightness(X) applied to the layout root. Immediate visual dimming that works on any display type.
- Screen blanking: Full-screen black overlay (z-[9999]) shown after the configured inactivity timeout. Touch anywhere to wake.
- Activity tracking: Resets on pointerdown/keydown events AND on WebSocket-driven NFC/scale changes (weight update, tag scan).
- Queries device data every 15s to read the current brightness and blank timeout values.
Daemon display_control.py — Simplified:
- Removed vcgencmd/wlopm/subprocess usage entirely
- _blank/_unblank are now state-tracking no-ops (log only)
- DSI backlight brightness via sysfs is preserved as a bonus for DSI displays
- Updated docstring to explain the architecture
3. Scale tab — redesigned with step indicator
Idle state: Same as before — weight card with tare/calibrate buttons.
Calibration wizard: Two-column layout:
- Left column (~64px): Vertical step indicator with numbered circles, checkmark for completed steps, and a connecting line
- Right column: Live weight bar (with stable/settling indicator), step-specific content (instructions or numpad), and action buttons pinned to bottom via mt-auto
The numpad buttons are min-h-[52px] with text-lg — large enough for touch on 1024x600. The weight info card is hidden during the weight entry step to maximize vertical
space.
Root cause: The daemon used wlopm for screen blanking, but wlopm was never installed. Additionally, the daemon runs as the spoolbuddy system user which has no access to
the Wayland socket, so Wayland-based tools can't work.
Fix in display_control.py:
- Replaced wlopm --off/--on with vcgencmd display_power 0/1 — this is a Raspberry Pi firmware-level command that's pre-installed and works without Wayland socket access
- Added shutil.which("vcgencmd") check at init to avoid repeated failures on non-RPi hardware
- Added explicit PermissionError handling for brightness writes with a helpful message about the video group
Fix in install.sh:
- Added video group to the spoolbuddy service user's groups (was: gpio, spi, i2c → now: gpio, spi, i2c, video), which grants access to both vcgencmd and sysfs backlight
files
Scale Tab Numpad
Root cause: On the 1024x600 kiosk screen (~376px available content height), the weight info card + numpad + action buttons exceeded the space, causing tiny buttons and
overlapping.
Fix in SpoolBuddySettingsPage.tsx:
- Hide the weight info card during weight entry step (calStep !== 'weight'), reclaiming ~70px
- Compact inline weight reading in the step header (small dot + monospace text) so users can still see the live scale value
- Larger numpad buttons: min-h-[56px] with text-lg font size (was no min-height, text-sm)
- Added active:scale-95 for tactile touch feedback
- mt-auto on action buttons to push them to the bottom, preventing overlap
- Removed the wrapping card around the calibration flow to save vertical padding
The Raspberry Pi kiosk has no physical keyboard and system-level virtual
keyboards (squeekboard, wvkbd) don't auto-show/hide with labwc/Chromium.
Add a react-simple-keyboard QWERTY keyboard that auto-shows on input
focus, with dark theme, shift/caps/backspace, email keys (@, .), and a
two-phase close that prevents ghost-click passthrough to elements below.
Inputs with data-vkb="false" opt out (e.g. SpoolBuddySettingsPage numpad).
