The GET /api/v1/support/debug-logging endpoint returned 500 when the
database contained a timezone-aware enabled_at timestamp written by
0.2.2b3. The duration calculation mixed offset-aware and offset-naive
datetimes, raising TypeError. Strip tzinfo when reading the stored value.
Two bugs prevented bed cooldown notifications from working:
1. Stale temperature data: After print completion, the printer sends
partial MQTT updates without bed_temper, leaving the cached value
frozen at the end-of-print temperature. The monitor polled for 30
minutes seeing the stale value above threshold, then timed out.
Fix: send periodic pushall commands to force fresh temperature data.
2. Missing fields in provider create endpoint: on_bed_cooled and all 7
queue event toggles were omitted from the NotificationProvider
constructor, silently discarding user selections on create (update
worked fine via dynamic setattr).
Also added debug logging to the bed cooldown polling loop.
The debug logging banner displayed a negative elapsed time (e.g. "-60m -59s")
equal to the server's UTC offset. datetime.now() stored local time without a
timezone indicator, but the frontend's parseUTCDate() interpreted it as UTC.
Use datetime.now(tz=timezone.utc) consistently for storing, parsing, and
comparing the enabled_at timestamp.
* Enhance link spool functionality with additional printer and AMS details
* Refactor linkSpool function to accept detailed context object for improved spooling integration

* Updates LinkSpoolModal test to work with recent spool location update changes
* Adds clear_location to unlink testing
* Refactor LinkSpoolRequest to remove ams_name and update location generation logic for improved clarity

0.2.2b3. The duration calculation mixed offset-aware and offset-naive
datetimes, raising TypeError. Strip tzinfo when reading the stored value.
* Expanded link logic to accept a generic spool tag (spool_tag, tray_uuid, or tag_uid) and validate 16/32-char hex values, including rejection of all-zero tags. Added a new unlink endpoint that clears Spoolman extra.tag for a given spool ID.
* Updated the link validation expectation to match the new 16-or-32-hex rule. Added an integration test for the new unlink endpoint to verify extra.tag is cleared and success is returned.
* Updated the link API call to send spool_tag instead of tray_uuid. Added a new unlinkSpool API helper that calls the new backend unlink route.
* Switched modal data source from inventory spools to Spoolman unlinked spools so the list matches the backend response you shared. Updated the link action to call Spoolman link directly and use trayUuid or tagUid as the slot tag.
* Refactored Spoolman card behavior so actions render correctly across linked/unlinked cases, and added support for an Unlink from Spoolman button under Open in Spoolman. Final UI rule now hides Unlink for Bambu Lab filament and shows it only for non-Bambu linked spools.
* Added fallback slot-tag generation so untagged slots can still be linked/unlinked reliably and linked spool lookups work consistently across AMS, AMS-HT, and external trays. Wired a new unlink mutation and passed per-slot unlink callbacks into the hover card, with query invalidation for linked/unlinked spool caches after unlink.
* Added/updated the noTrayUuid message to reflect that either tray UUID or tag UID is required when no slot tag is available. This keeps error text aligned with the new tag fallback and modal behavior.
* Added noTrayUuid message in the other languages. The translation was done using Google Translate.
* Updated LinkSpoolModal tests to use Spoolman API instead of inventory API, with new UnlinkedSpool data structure and Select Spool UI text.
* Adds hashSerialToHex32, uses new function in getFallbackSpoolTag and updates all uses. This ensures we're generating a fallback spool tag using the printers serial number rather than the database ID for consistency.
* Removes 'import json' from unlink_spool and moves to the top of the file.
* Removes hasUnlinkedSpools and related references since it's no longer used
* Removes noTrayUuid from translations and references in components.
* Adds confirmation dialog before fully unlinking spool from Spoolman
* Adds unlinkConfrimTitle and unlinkConfirmMessage. All languages other than English were done using Google Translate
* Fixes unlink toast to use dedicated unlinkSuccess and unlinkFailed keys.
* Changes tag priority on spoolTag, fixes type error by adding non-null assertion to spoolTag
* Switches around tag_uid and tray_uuid on const trayTag

The debug logging banner displayed a negative elapsed time (e.g. "-60m -59s")
equal to the server's UTC offset. datetime.now() stored local time without a
timezone indicator, but the frontend's parseUTCDate() interpreted it as UTC.
Use datetime.now(tz=timezone.utc) consistently for storing, parsing, and
comparing the enabled_at timestamp.
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.
Virtual printers in Queue mode now have an "Auto-dispatch" setting.
When enabled (default), prints start automatically — preserving current
behavior. When disabled, prints are added with manual_start so they
wait for manual dispatch from the queue UI.
Checkbox selection + "Delete Selected" button in Settings > Filament
for both Spool Catalog and Color Catalog. Adds POST bulk-delete
endpoints and translations for all 7 locales.
P2S uses hardened steel rods, not carbon fiber. Move P2S from
carbon rod classification to new steel_rod category with its own
"Lubricate Steel Rods" / "Clean Steel Rods" maintenance tasks.
visibility into AMS spool assignments on printer cards without exposing
the full Inventory page (#635). The list_assignments endpoint now
requires this new permission instead of inventory:read. All default
groups (Administrators, Operators, Viewers) include it for backward
compatibility.
Closes#634
Files added to a project from the archive (status="archived") were
incorrectly counted in completed_prints and parts_progress stats.
Only status="completed" (actually printed) now counts toward completion.
All filament mapping dropdowns (single-printer, multi-printer, and
"Print to Any" model-based) showed only the base material type (e.g.
"PLA") without distinguishing subtypes like "PLA Basic" vs "PLA Matte",
making entries with different subtypes but same color look identical.
Backend: Add tray_sub_brands to available-filaments response and include
it in the dedup key so different subtypes of the same color appear as
separate entries.
Frontend: Show tray_sub_brands in FilamentMapping, FilamentOverride, and
PrinterSelector dropdowns, falling back to base type when unset. Add
traySubBrands field to LoadedFilament interface.
- Add 12 backend integration tests for AMS labels API (GET/PUT/DELETE,
serial resolution, synthetic key fallback, whitespace handling, validation)
- Add 10 frontend tests for FilamentSlotCircle component (rendering,
border styles, background colors, text contrast inversion)
- Fix ruff W293 trailing whitespace in inventory.py from contributor fix
- Add ams_label model import to test conftest.py
- Update CHANGELOG, README, website features page, and wiki AMS docs

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.
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.
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
* 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'

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.
SpoolBuddy's "Link to Spool" used the generic updateSpool API which only
set tag_uid, leaving tag_type and data_origin empty. Now uses linkTagToSpool
with tag_type='generic' and data_origin='nfc_link'.
Added a "Weight Check" inventory column (hidden by default) that compares
each spool's last scale measurement against calculated gross weight with
±50g tolerance. Shows green check for match, yellow warning + sync button
for mismatch. Backend stores last_scale_weight and last_weighed_at on each
spool when weight is synced via SpoolBuddy. Includes edge case handling
when scale weight < core weight. i18n keys added for all 6 locales.
The assign_spool endpoint sent wrong MQTT field values for user presets,
causing the slicer's AMS slot detail card to show all fields empty.
Two bugs: (1) cloud API was called with the raw slicer_filament value
including its version suffix (e.g. PFUS9ac902733670a9_07), returning 404;
the silent fallback sent setting_id as tray_info_idx instead of the real
filament_id; (2) no SlotPresetMapping was saved after assignment.
Now strips version suffixes before cloud lookup, resolves the real
filament_id via cloud API (with local preset and generic fallbacks),
includes brand in tray_sub_brands, and saves slot preset mapping.
Print Activity now shows an hourly heatmap (hours x days) for timeframes
≤7 days and dynamically adjusts calendar months for longer ranges.
Adds hourly granularity to Filament Trends, persists timeframe selection,
fixes optional chaining in QuickStatsWidget, and fixes UTC/local timezone
mismatches in date key generation. Also hardens the /archives/slim limit
param and fixes empty query string handling in API client.
- Add lightweight GET /archives/slim endpoint with column-level SELECT
(13 fields vs 46), skipping duplicate detection for ~70-80% payload
reduction on the stats dashboard
- Add ArchiveSlim Pydantic schema and TypeScript type
- Switch StatsPage and FilamentTrends to use ArchiveSlim
- Fix critical bug in failure_analysis.py: use effective_days for week
count, separate non-date filters, build fresh week_filter per loop
- Fix busiestDay timezone bug: parse YYYY-MM-DD with split() + local
Date constructor instead of new Date() which creates UTC midnight
- Fix success streak ordering: sort by completed_at || created_at
instead of created_at alone
- Add 6 integration tests for /archives/slim endpoint
Add Print Time of Day, Color Distribution, and Records widgets to the
Stats page. Extract shared MetricToggle component for consistent
weight/prints/time toggles. Add date range filtering to archives and
stats API endpoints. Reorganize widgets into parent cards (Printer Stats
and Filament Trends) and fix Dashboard layout persistence for new widgets.
- Replace TagDetectedModal with inline SpoolInfoCard/UnknownTagCard
in dashboard right panel (known spools show assign/sync/close,
unknown tags show add-to-inventory/link/close)
- Rewrite AssignToAmsModal as full-screen overlay reusing AmsUnitCard,
with AMS-HT and external slot support, single assignSpool API call
- Remove printer selector from assign modal (uses top bar selection)
- Extract filament_id <-> setting_id conversion to shared utility
(backend/app/utils/filament_ids.py), used by inventory + cloud routes
- Normalize slicer_filament in assign_spool to derive proper
tray_info_idx and setting_id for MQTT (was sending setting_id="")
- Rename SpoolBuddy top bar status label "Online" -> "Backend"
- Remove weightStable guard from sync weight button
Four support package improvements:
1. Mask first two octets of subnet IPs in support info
(192.168.1.0/24 → x.x.1.0/24) to avoid leaking private network
addresses.
2. Fix Docker network_mode_hint detection. The old heuristic
(interface count > 2) always reported "bridge" on single-NIC
hosts because get_network_interfaces() excludes Docker
interfaces. Now checks for docker0/br-*/veth* visibility via
socket.if_nameindex() — these are only visible in host mode.
3. Parse MQTT "fun" field at top level of payload (not just inside
"print" key). Some firmware versions send it there, which
explains why developer_mode was null for most users.
4. Add virtual_printers section to support info with mode, model,
enabled/running status, and pending file count.
Fix camera button permissions & ffmpeg process leak (#550)
Camera button on printer card was clickable without camera:view
permission. ffmpeg processes (~240MB each) accumulated after closing
camera streams because: (1) stop endpoint called terminate() without
wait()/kill(), (2) HTTP disconnect detection only ran between frames
so was blocked when the generator was stuck on stdout read, and
(3) no mechanism caught processes orphaned by generator abandonment
or app restarts.
- Add camera:view permission check + tooltip to camera button
- Fix stop endpoint: terminate() → wait(2s) → kill() → wait()
- Add background disconnect monitor (polls every 2s, kills ffmpeg
directly on disconnect)
- Add periodic /proc scan (every 60s) that SIGKILLs any ffmpeg
with rtsps://bblp: not in an active stream
- Add noCamera i18n key to all 6 locales
- Fix camera API test mocks for async wait() and pid attribute
The tare and calibrate buttons on the Settings page queued commands
but never executed them due to five broken links:
1. Daemon received tare command but never called scale.tare()
2. No endpoint to persist tare offset back to backend DB
3. Heartbeat never called scale.update_calibration()
4. Heartbeat response with stale values overwrote new tare to zero
5. set-factor used DB tare_offset (stale/zero), producing wrong
calibration factor — empty scale showed ~5000g
Fixed daemon to execute tare, persist result, and propagate
calibration. Calibration step now captures raw ADC at tare time
and sends it with step 2, making factor computation self-contained.
Replaced calibration weight input with compact touch numpad for
the RPi kiosk's 1024x600 touchscreen (no physical keyboard).
The tare and calibrate buttons on the Settings page queued commands
but never executed them due to three broken links:
1. Daemon received tare command via heartbeat but never called
scale.tare() — the ScaleReader was available in shared dict
but unused
2. No API endpoint for the daemon to report the new tare offset
back to the backend DB, so tare results were lost
3. Heartbeat updated config but never called
scale.update_calibration(), so ScaleReader kept initial values
Added set-tare endpoint + API client method, and fixed heartbeat
loop to execute tare, persist the result, and propagate calibration
changes to the ScaleReader instance.
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)
Add weight_locked flag to spools that auto-sets when weight_used is
explicitly updated via the API. Both the MQTT AMS remain% auto-sync and
the manual force-sync endpoint skip locked spools. Usage tracker delta
tracking is unaffected. Users can re-enable AMS sync by setting
weight_locked to false.
Queue endpoints now return filament_type, filament_color, layer_height,
nozzle_diameter, and sliced_for_model from the archive or library file.
Previously this data was only available via the archive API.
All backend timestamps used datetime.now() (server local time) or the
deprecated datetime.utcnow(). The frontend's parseUTCDate() assumes
timestamps without timezone indicators are UTC and appends 'Z', so
stored timestamps were off by the timezone offset when the container's
timezone wasn't UTC.
Backend: replaced datetime.now() and datetime.utcnow() with
datetime.now(timezone.utc) across 16 files (~80 call sites) for all
database fields and DB comparisons. Cosmetic timestamps (filenames,
user-facing local time formatting) intentionally left as local time.
Frontend: replaced 13 new Date(backendTimestamp) calls with
parseUTCDate() across 8 files to correctly interpret UTC timestamps.
When scheduling a print to "any printer" (model-based assignment),
users can now override the 3MF's original filament choices per slot.
The override dropdown shows compatible filaments loaded across all
printers of the selected model, filtered by type and nozzle (H2D).
The scheduler matches against overridden type/color instead of the
original 3MF values, preferring printers with exact color matches.
Backend:
- New GET /printers/available-filaments endpoint (aggregates loaded
filaments across printers of a model, includes extruder_id for
dual-nozzle nozzle-aware filtering)
- New filament_overrides JSON column on print_queue table
- Scheduler applies overrides before AMS mapping, clears tray_info_idx
on overridden slots so color matching takes priority
- Printer selection prefers printers with most override color matches
Frontend:
- New FilamentOverride component with per-slot override dropdowns
- Type-filtered options (PLA slots only show PLA)
- Nozzle-aware filtering (H2D: only shows filaments on correct extruder)
- Integrated into PrintModal for model-based queue mode
Tests:
- 11 backend unit tests (color match counting, override application)
- 12 frontend tests (rendering, type/nozzle filtering, interactions)
i18n: All 6 locales (en, de, fr, it, ja, pt-BR)
SpoolBuddy turns a Raspberry Pi 4B with a PN5180 NFC reader and
NAU7802 scale into a filament management station that integrates
with Bambuddy via REST API and WebSocket.
Backend: SpoolBuddyDevice model, 10 REST endpoints (/spoolbuddy/*),
6 WebSocket broadcast types, background offline-detection watchdog.
RPi daemon: asyncio service with concurrent NFC polling (300ms,
MIFARE Classic + Bambu HKDF key derivation), scale reading (10 SPS,
5-sample moving average, stability detection), and 10s heartbeat
with exponential backoff reconnect.
Frontend: kiosk-optimized 1024x600 UI at /spoolbuddy with Dashboard
(live weight + NFC spool detection), AMS Overview, Inventory,
Printers, and Settings pages. useSpoolBuddyState reducer hook
driven by WebSocket CustomEvents.
i18n: all 6 locales (en, de, fr, it, ja, pt-BR).
The rename endpoint updated `filename` but not `file_metadata.print_name`,
which the UI uses as the primary display name. Since print_name is extracted
from the 3MF at upload, it always took precedence over the renamed filename.
Now also updates print_name in file metadata when present.
Two bugs caused spool assignments to always configure AMS slots with
generic Bambu filament IDs (e.g. GFB99 "Generic ABS") instead of the
spool's actual slicer preset:
1. PFUS* IDs (cloud-synced custom presets) were blanket-rejected and
replaced with generic IDs in both assign_spool and configure_ams_slot
2. Generic fallback IDs (GFB99, GFL99, etc.) were treated as "good"
presets by the slot-reuse logic, making them sticky once set
New priority: spool's own slicer_filament > slot's non-generic preset
(same material) > generic fallback.
