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.

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.
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
When FTP download of a 3MF fails (e.g. BambuStudio-initiated prints),
the fallback archive has file_path="". Path.exists() on
settings.base_dir / "" resolves to the base directory itself and
returns True, so ZipFile() then fails with [Errno 21] Is a directory.
Replace .exists() with .is_file() across all 15 archive route checks
and 1 in main.py. Add file_path truthiness guard for finish photo
capture to prevent saving photos under the base directory.
Add Quick Add mode to the spool form for simplified entry (material +
color + weight only), and a quantity field (1-100) for creating multiple
identical spools at once. Stock spools (no slicer profile) are computed
rather than stored — any spool without slicer_filament shows an amber
"Stock" badge. New filter chips (All/Stock/Configured) on the inventory
page. Backend bulk endpoint creates N spools in one transaction.
Backend:
- SpoolBulkCreate schema with quantity validation (1-100)
- POST /inventory/spools/bulk endpoint
Frontend:
- Quick Add toggle in SpoolFormModal (create mode only)
- Quantity field in FilamentSection (both modes)
- bulkCreateSpools API method and bulkCreateMutation
- Stock column (hidden by default) and stock filter chips
- Inline error rendering moved into FilamentSection
- CellCtx extended with t() for translatable cell content
Tests:
- 13 backend tests (schema validation + endpoint logic)
- 10 frontend tests (validateForm quickAdd + UI behavior)
i18n: 6 locales (en, de, fr, it, ja, pt-BR)
Docs: CHANGELOG, README, website features, wiki inventory
When a print was started from BambuStudio (not Bambuddy), the
auto-archive has an empty file_path. The photo save code uses
base_dir / Path("").parent which resolves correctly, but the
serve/upload/delete endpoints used (base_dir / "").parent which
goes one directory level too high — returning 404 despite the
photo existing on disk.
The log sanitizer only used regex patterns, missing arbitrary user-chosen
strings (printer names, usernames). Tasmota smart plug credentials were
logged verbatim in URLs by httpx.
- Make _sanitize_log_content() database-aware: query Printer names/serials,
User usernames, and Bambu Cloud email for exact-string replacement
(longest-first, skip <3 chars to prevent over-redaction)
- Fix serial regex leaking first 3 chars (remove capture group partial
redaction), add case-insensitive flag
- Move Tasmota credentials from URL-embedded (http://user:pass@host) to
httpx auth= parameter so they never appear in logs
- Add URL credentials regex as defense-in-depth for user:pass@ in logs
- Add 'username' and 'path' to settings sensitive_keys filter (catches
smtp_username, slicer_binary_path in support-info.json)

The previous fix passed target_model from the frontend, but this relied
on printer.model being set on the client. When a printer was added
without selecting a model (the field is optional), the frontend sent no
target_model parameter, causing the OR logic to be bypassed entirely —
the widget only queried printer_id=X and missed unassigned model-based
items.
The backend now looks up the printer's model from the database when
target_model isn't provided by the client, ensuring "Clear Plate &
Start Next" appears for model-based queue jobs regardless of how the
printer was configured.
Users on the Docker `latest` tag were seeing update notifications for beta
releases (e.g. v0.2.1b) they couldn't install. The update checker now fetches
/releases instead of /releases/latest and filters by parse_version() prerelease
detection. A new toggle in Settings (default: off) lets users opt in to beta
notifications.
When a print was queued with "Any [Model]", the queue widget only
queried items with printer_id=X after dispatch, missing the next
pending model-based item (printer_id IS NULL, target_model="P1S").
The "Clear Plate & Start Next" button never appeared, leaving the
scheduler stuck reporting "Busy".
Add optional target_model query parameter to GET /queue/. When
combined with printer_id, uses OR logic to also return unassigned
items whose target_model matches. The frontend now passes the
printer's model through PrinterQueueWidget to this query.
