The Filament Mapping panel reported "(Ready)" with a green tick for a slot
where the slice wanted dark red and the auto-matched tray held dark green.
Manually picking that same tray reported the mismatch correctly, which is
what made it obvious something was inconsistent.
Auto-match ranks candidates by tray_info_idx first, and a uniquely-matching
preset was accepted as definitive on the premise "same preset = same spool =
same colour". The preset names the variant, not the spool: GFA00 is PLA
Basic, GFA01 PLA Matte, GFA17 PLA Translucent, in every colour Bambu sells.
The reporter's own bundle has eight GFA00 trays in eight colours. With one
Matte spool loaded, every Matte requirement idx-matched it and the colour
comparison was never reached - which is why this surfaced on PLA Matte and
not on Basic, where several spools are usually loaded and the match falls
through to the branch that does compare colours.
The verdict now comes from the tray that was selected rather than from which
rule selected it, and both branches share one comparison so they cannot
drift apart again. Selection is unchanged - the right variant still wins per
mismatch and the slot stays selected.
A requirement with no colour at all is treated as satisfied rather than
mismatched; 3MFs that omit it parse to "" and there is nothing to disagree
with. That also affects the manual branch, which used to flag it.
No dispatch change: _get_missing_force_color_slots already required an exact
colour, so force colour match was gated correctly throughout.
The hook is mounted globally in WebSocketProvider, so refetchInterval on its
per-printer status queries added one request per printer every 30s on every
page. The Printers page already runs that fallback on the same query key, and
useWebSocket writes ['printerStatus', id] straight into the cache, so the poll
bought nothing outside the Printers page and cost a request per printer per
tab everywhere else.
Also captures document.title at mount instead of restoring to a hardcoded
'Bambuddy', so the default no longer has to be kept in sync with index.html.
jsdom has no canvas backend, so getContext('2d') logged a "Not implemented"
jsdomError with a full React stack on every run of the hook's tests, and the
favicon branch bailed on the null context and went untested. Stubbing
getContext/toDataURL removes the noise and lets the ring code run, so the
favicon swap and the restore-on-toggle-off path are now asserted.
Optional and off by default, toggled under Settings -> Appearance. When enabled, the browser tab shows the soonest-finishing print's percentage plus a green progress-ring favicon, updated live over the existing WebSocket. The preference is stored per-browser in localStorage.
Adds the usePrintProgressTitle hook (with tests), a ThemeContext preference, the Settings toggle, i18n strings for all locales, and a README entry.
Assigning a spool to an AMS tray pushed ams_filament_setting +
extrusion_cali_sel and reported success immediately, whether or not the
tray accepted it. A silently-dropped assignment never surfaced, and since
a print only deducts from the spool on the exact tray it pulls from, it
also recorded no filament usage - which made the whole thing feel random.
Read the AMS telemetry back after every assign (inventory assign_spool and
the Configure Slot modal) and toast the outcome: loaded when the tray
echoes the pushed tray_info_idx, a warning when the filament loaded but the
K-profile (cali_idx) did not, or not-confirmed after ~30s. Verification
uses the periodic per-tray push (the command ack hardcodes sequence_id 0
and can't be correlated); an on-demand pushall is nudged so it lands
quickly. Covers regular AMS, AMS-HT and external slots; stays silent rather
than inventing a failure if the printer goes quiet. The read-back check
runs on every AMS push because the change-hash excludes tray_info_idx.
A P1S queue row with use_ams=true but ams_mapping=[-1] was silently
printed with no AMS, starting against the empty external feed and pausing
with a runout. Two faults combined:
- start_print treated -1 (unresolved) the same as >=254 (explicit
external) when deciding to force use_ams=False. Only genuine external
now downgrades; -1 never does.
- The scheduler trusted a stored [-1] as "already resolved" and passed it
through. It now recomputes from live AMS trays whenever the stored
mapping is entirely unresolved, and clears it if nothing matches rather
than sending a doomed command.
Frontend: the Print dialog no longer serializes an all-[-1] mapping while
the printer status is still loading (the hook returns no mapping), and
submit waits for AMS status with a "Waiting for AMS status" notice.
Tests: new backend + frontend regression coverage; corrected one existing
test that pinned the old [-1] -> use_ams=False behavior.
Selecting several plates hid the filament mapping panel but did not stop the
modal sending a mapping. With no single plate selected it fell back to the
whole file's filament list -- the union of every plate -- and matched against
that. Tray assignment is stateful, so where plate 1 prints red on slot 1 and
plate 2 prints red on slot 2, slot 1 claimed the only red spool and slot 2 fell
through to a type-only match on black. That one mapping went out with every
plate, and the scheduler uses a stored mapping verbatim, so plate 2 printed in
the wrong colour -- decided by a panel the user never saw.
Fetch each selected plate's requirements and map them separately: one panel per
plate, named after it, with its own tray overrides, and each queue item carries
its own plate's mapping. A fan-out across several printers would be a panel per
plate per printer, so those items carry no mapping and the scheduler maps each
plate against the printer it picks. Model mode is unchanged -- no printer means
no trays to map onto.
The tray matcher existed twice and this needed a third caller, so extract it
once and have both existing paths delegate; its 62 tests pass unchanged.
The bug only reproduces with a realistic query cache -- the shared test harness
sets gcTime: 0, which evicts the union and makes the modal look innocent -- so
the new modal tests bring their own client.
The sponsor toast re-fired on every fresh browser session. The backend
owns the 14-day cooldown but only persists the anchor (last_shown_at) and
the seen-milestone record inside POST /sponsor-prompt/dismiss, and the hook
only called dismiss from the "View supporters" CTA onClick. A user who saw
the toast but never clicked the CTA persisted no state; the per-tab
sessionStorage guard hid the re-fire within one session, but every new
session re-checked against empty state and re-showed the same milestone.
Record the toast as shown the moment it renders (POST /dismiss right after
showPersistentToast) so display is what arms the cooldown. CTA click stays
optional and just navigates. Frontend-only; backend cooldown logic unchanged.
After the GHSA-r2qv gate (b7d7c825), /api/v1/ws needs a token from
POST /api/v1/auth/ws-token (Permission.WEBSOCKET_CONNECT). When the mint
failed, useWebSocket swallowed the error, opened a tokenless socket, the
server closed it 4401, and ws.onclose rescheduled connect() every 3s -
an endless loop that hammered /auth/ws-token. The dominant trigger is a
validly-logged-in user whose group lacks WEBSOCKET_CONNECT (mint returns
403). A secondary leak: the unmount-triggered onclose could schedule a
post-unmount reconnect.
Classify the mint failure: 401 (JWT expired; request() already clears it
and dispatches auth:expired) or 403 (valid session, missing permission;
degrade to REST polling) now stop the hook - no tokenless socket, no
reconnect. A 4401 close is terminal. Network/5xx still reconnect. A
disposedRef set in cleanup before close() prevents the unmount-race
reconnect. Same 401/403 no-open guard applied to StreamOverlayPage.
Also surface a one-line hint under the WebSocket permission in the group
editor (all 11 locales) explaining that live updates need it and fall
back to polling without it - rather than auto-granting the permission,
which would partly undo the GHSA-r2qv gate.
PR A/B turned the slice modal's preset bundle into a one-click dispatch
with a pinned target printer. PR C closes the original issue: operators
type in a number of copies, Bambuddy slices once and distributes prints
across a fleet per the pipeline's chosen fanout strategy. A new dashboard
surfaces every run with filters, expandable per-copy status, cancel,
and retry-failed-copies. WS pushes keep everything live.
Backend
- copies field on POST /run, capped by new pipeline_max_copies setting
(default 50, hard cap 1000). PipelineRun.parent_run_id chains retries.
- SlicerPipelineUpdate accepts target_kind (specific_printer /
printer_class), target_model_class, fanout_strategy.
- Eligibility matcher branches: class-targeting enumerates matching
Printer rows, runs per-printer checks via a status_lookup closure,
returns printer_reports[]. New issue kinds: no_class_matches,
class_not_set.
- _pick_assignments distributes copies per strategy:
- max_parallel: target_model set, printer_id None — scheduler picks
- round_robin: copy i → eligible[i % N], fixed printer_id
- fill_one_first: all copies pinned to eligible[0]
All three reuse the slice-once path through slice_dispatch.enqueue.
- New routes:
- GET /pipeline-runs (paginated, filterable by pipeline + status)
- POST /pipeline-runs/{id}/retry-failed (creates child run with
copies = failed+cancelled count, parent_run_id set)
- Cancel cascades to all N queue entries (only pending/queued)
- _roll_up_run_status computes run-level status from per-job statuses;
introduces partial_failure for "some completed, some failed".
- ws_manager.broadcast_to_user emits pipeline_run_updated on every
state transition with the full materialised response.
Frontend
- Pipeline editor: target_kind radio + class picker (filtered to
installed models) + fanout-strategy radio. Read-only row shows
"X1C · Round robin" for class pipelines.
- RunWithPipelineModal: copies number input bounded by
settings.pipeline_max_copies. Accepts class-targeted pipelines.
- Settings → Workflow → Queue & Dispatch: new "Slicer Pipeline limits"
card with the max-copies input.
- New /pipelines/runs dashboard page (sidebar entry, gated on
pipelines:read). Two-filter dropdown, 25-per-page pagination, per-row
expandable to job list, Cancel + Retry-failed buttons.
- useWebSocket case for pipeline_run_updated invalidates both
pipeline-runs-all and pipeline-runs/{id} query keys.
FTP push to the printer into the server-side scheduler tick. That
removed the browser-side upload the old XHR-progress modal listened
to — users only saw the queue item flip to "active" with no visibility
into the FTP push + the H2D/H2D Pro 80-210 s project_file digestion
window before the printer actually started.
Port the legacy bg-dispatch toast rendering from
0b43ac0d:frontend/src/contexts/ToastContext.tsx lines 510-650 back in
place verbatim — same DOM tree, same Tailwind classes, same
formatFileSize bytes line, same uppercase status chip, same collapse
chevron, same awaitingPrinter derivation, same auto-dismiss. The only
adapt is the event ingestion: a useEffect maps the four scheduler-side
WS events to the legacy DispatchToastJob shape.
The toast materializes when the FTP push to the printer ACTUALLY
STARTS (queue_item_uploading) — NOT on POST /queue. A draft that
fired at queue-add made the toast jump to "Dispatched" before any
upload had happened.
Four backend WS events drive it: uploading (carries printer_name +
total_bytes), upload_progress (throttled at 200 ms / 256 KB to match
legacy background_dispatch.py:614-615 1:1, first call always emits,
completion always emits; an _UploadProgressBridge bridges from the
FTP executor thread to the asyncio loop), acked (printer transitioned
out of pre_state), failed (with a reason key the toast looks up as
dispatchToast.failed.{reason}). No queue_item_dispatched event: the
legacy path kept status=processing from upload start until printer
ack, "Awaiting printer..." derives from upload_progress_pct >= 99.9
(legacy uploadDoneAwaitingPrinter trick).
Per-user routing: WS connect resolves the principal username to
User.id once and stashes it on websocket.state, so
ws_manager.broadcast_to_user filters O(connections). Auth-disabled
installs route user_id=None to all connections — matches the legacy
single-user behaviour. The watchdog receives created_by_id through a
new kwarg so the static method can still emit acked without
re-fetching the queue item.
New setting "Auto-add unknown RFID spools" under Settings -> Filament -> Filament Tracking,
default ON for back-compat. When turned off, the backend stops auto-creating an inventory
record for an unknown RFID tag and instead broadcasts an unknown_tag WS event that pops
a global confirmation modal in the Bambuddy UI showing the printer / AMS-X label / slot /
material / colour. Add or Cancel; no nag on every MQTT push.
Backend
- Module-level _unknown_tag_last_broadcast dict dedupes per (printer, slot, tag). Set is
committed AFTER ws_manager.broadcast() returns so a crashed broadcast doesn't poison
the dedup and permanently silence the slot.
- Empty-slot MQTT push clears that slot's entry, so remove+reinsert reliably re-prompts.
- Successful matches via get_spool_by_tag / find_matching_untagged_spool / create_spool
also clear the entry so a future tag swap re-prompts.
- Tray data (tray_type, tray_color, tray_sub_brands, tray_count) shipped in the WS payload
directly so the modal renders the real material / colour instead of relying on the
React Query cache that lags the WS event by several seconds.
- Two new endpoints back the modal's confirm action:
POST /api/v1/inventory/spools/from-slot (INVENTORY_UPDATE)
POST /api/v1/spoolman/spools/from-slot (FILAMENTS_UPDATE)
Both look up the slot's tray data server-side and create + auto-assign atomically.
- Spoolman /from-slot now raises HTTP 500 when the slot-assignment INSERT fails instead
of returning success while the DB rolled back the binding.
- sync_ams_tray gained an optional auto_add_unknown_rfid kwarg (default True so existing
callers are unaffected); auto-sync and both manual sync routes thread the setting.
Frontend
- useUnknownTagPrompt hook listens for the unknown-tag CustomEvent, reads the tray fields
out of the event detail, and feeds a single-modal queue. No long-lived dismissed set;
the backend dedup handles spam suppression.
- UnknownSpoolModal wraps the existing ConfirmModal with a material + colour-swatch
preview block.
- Mounted in Layout.tsx alongside useSponsorPrompt so SpoolBuddy kiosk / login / setup
routes are excluded.
- getAmsLabel moved to utils/amsHelpers.ts; ConfigureAmsSlotModal.tsx and PrintersPage.tsx
both import the shared version (canonical AMS-A / HT-A / External labels).
- AppSettings TS interface gained spoolman_enabled, auto_add_unknown_rfid, spoolman_url
so the runtime cast in the hook is no longer needed.
- SpoolmanSettings.tsx gets a new toggle row in the Filament Tracking card, visible in
both built-in and Spoolman branches; auto-save + toast already wired.
Adds page-wide drag-and-drop file upload to the File Manager
tab — drop any file anywhere on the page and the upload modal
opens pre-populated with the dropped files. The Upload Files
button still works for click-to-browse.
Also fixes the Archives drag-cancel bug @maikolscripts reported
in the same issue: cancelling a drag (drag back outside the
browser, Escape mid-drag, or release outside the page) used to
leave the overlay stuck until page refresh.
Both pages share a new hook usePageFileDrop. The fix:
- relatedTarget containment check (catches drag-out-of-window)
- document-level drop / dragend / keydown(Escape) listeners
that only register while isDraggingOver === true, so the
three cancel paths all reset uniformly
FileUploadModal gains an optional initialFiles prop so the
File Manager page can pre-seed the modal from a page-wide
drop. seededInitialRef guards against re-adding on re-renders.
Permission gate: File Manager drop zone disabled when the
user lacks library:upload, so a viewer-tier user doesn't get
a misleading overlay.
Reported off-list by a corporate supporter running a multi-operator
farm shift. Backend already rejects double-sends with HTTP 409 (see
background_dispatch._dispatch at lines 283-290), so no double-print
was possible, but PrinterSelector consulted only PrinterStatus.state
({IDLE, FINISH, FAILED}) to decide whether a printer was selectable.
PRINT_START is the only signal that flips the printer out of IDLE, so
during the upload + print-command + firmware-ack window the card
stayed clickable and operators only found out after submitting.
New useDispatchedPrinterIds hook subscribes to the existing
background-dispatch WebSocket event (already consumed for the toast
overlay), collects printer_ids from dispatched_jobs + active_jobs,
and exposes them via useSyncExternalStore so every PrinterSelector
instance shares one snapshot. OR'd into isPrinterBusy; badge label
flips to "Dispatching..." instead of a misleading "Idle".
No backend change — the reservation already exists, the UI just
didn't reflect it. No behaviour change for add-to-queue / edit-queue
modes (disableBusy stays false for those).
ghcr.io pull baseline (~10k/day rising → ~8-12k active installs) puts
sponsor conversion at 0.08% — roughly an order of magnitude under
industry-benchmark for OSS with visible CTA. The Settings banner from
0d4b9d4e gives passive every-visit visibility on one page; this adds
opt-out-able active visibility at moments where the user has just
earned something with Bambuddy.
Five trigger families with a 14-day cross-family cooldown: prints
(100/500/1000/2500/5000), cost (100/500/1000 tracked filament +
energy), archives (50/250/1000), anniversary (1 year), version-update
(re-armable on each major bump). New sponsor_toast_state table with
nullable user_id so auth-disabled installs get the same trigger logic
through one code path (NULL-keyed install-default row).
Two tightly-coupled deliverables in one drop -- a new AMS Filament Backup
status/control surface, and the #1766 fix that depends on it.
Added -- AMS Filament Backup status + control
- Parse bit 18 of top-level print.cfg into PrinterState.ams_filament_backup
on every push_status. Verified against OrcaSlicer source
(DeviceManager.cpp:4961) and a live H2D ON/OFF capture. Tri-state
(None = A1 family / pre-cfg push) preserves today's behaviour.
- Hold-timer guard (3 s) prevents stale frames from flickering the badge
back to the printer's old cfg after a user-initiated toggle.
- POST /printers/{id}/ams-backup toggle, set_ams_filament_backup() client
method calling _set_print_option("auto_switch_filament", enabled).
- GET /printers/{id}/inventory-remain endpoint exposes the same map the
dispatcher uses (internal and Spoolman modes both work uniformly).
- Small icon badge in the printer card's "Filaments" section header
(placement reads as printer-wide because the cfg bit is printer-wide,
not per-AMS). Click to toggle, success toast.
- 5 i18n keys x 11 locales for the badge UI.
Fixed -- #1766: prefer_lowest didn't pick lowest, ignored backup state
- Backend gate in _compute_ams_mapping_for_printer: coerce prefer_lowest
to False when status.ams_filament_backup is False; log the skip.
- New effectivePreferLowest(setting, backup) helper applied at every
frontend sort entry point: single-printer PrintModal, multi-printer
hook per-printer, PrinterSelector InlineMappingEditor, FilamentMapping
standalone editor (the last had NO preferLowest awareness at all
before this change).
- New preferLowestSortKey(f, inventoryByTrayId) mirrors backend's two-tier
key exactly, including the banding tie-break (regular AMS < AMS-HT <
external) so the client-side pre-compute matches the dispatch-time pick.
An earlier draft used a flat `amsId * 4 + trayId` priority which gave
external slots (ams_id = -1) a NEGATIVE priority -- caught in code
review before commit.
- Settings -> Filament -> "Prefer lowest remaining filament" gets an
explanatory note about the printer-side AMS Backup dependency, with
i18n key in all 11 locales.
external-spool extruder routing (#1257)
X2D with 0 AMS units and two external spools (Ext-L feeding left
extruder, Ext-R feeding right) showed "Required filament type not
found in printer" even when the matching filament was physically
loaded. Cause: useFilamentMapping derived dual-nozzle status from
ams_extruder_map being non-empty -- that map is populated from AMS
info bits, so dual-nozzle printers without AMS got an empty map
and hasDualNozzle=false. External spools then fell through to
extruderId=undefined, and the nozzle-aware filter rejected every
candidate because undefined !== 0/1.
Prefer the hardware-reported printerStatus.nozzles array length as
the dual-nozzle signal -- populated regardless of AMS configuration
-- and keep the ams_extruder_map branch as fallback for older
firmware that might not surface nozzles. Affects all dual-nozzle
printers running without AMS: X2D, H2D, X2 Pro.
Regression test pins both layers the bug straddled --
buildLoadedFilaments extruderId assignment per external spool, and
computeAmsMapping picking the correct external for a per-nozzle
requirement -- so a future change that re-breaks either fails CI.
feat(spoolman-inventory): squashed feature work for rebase onto dev
Squashed all commits from feature/spoolman-inventory-ui onto a single commit
to enable a clean rebase onto dev. Original per-commit history preserved at
backup tag backup/spoolman-inventory-ui-prerebase-20260507-105721.

The FTS routes any AMS slot to either extruder, so AMS info reports
bits 8-11 = 0xE (uninitialized) and ams_extruder_map ends up empty.
The print modal's per-nozzle dropdown filter then hides every loaded
slot, leaving the user with an empty filament dropdown.
Detection: parse print.device.fila_switch from MQTT push_status into a
new FilaSwitchState dataclass on PrinterState; surface it through the
GET /printers/{id}/status response as a nullable FilaSwitchResponse.
Frontend: useFilamentMapping and FilamentMapping skip the per-extruder
filter when fila_switch.installed is true. Slots currently fed into a
track display an [L]/[R] routing badge in the dropdown so the user
can see where the FTS is currently routing them.
Tests: 4 backend unit (TestFilamentTrackSwitchDetection), 2 backend
integration (status route), 2 hook regression, 2 component regression.
On auth-enabled instances, logging out and back in left the File Manager
(and occasionally the Archives page) full of broken thumbnails until a
manual page reload. Thumbnail URLs are gated by a short-lived camera
stream token that <img> tags cannot send via Authorization headers, so
the token is appended as ?token=… at render time.
Two races broke this after sign-in:
1. The token query was keyed on ['camera-stream-token'] alone and fired
while the user was still on the login page. It 401'd, React Query
cached the failure with a 50-minute staleTime, and nothing invalidated
it after login — the token never arrived.
2. Even when the token did arrive, the module-level variable holding it
was not reactive, so pages that had already rendered kept serving
image URLs with no token in them.
Fixes:
- Include user.id in the query key and gate with
`enabled: authEnabled ? !!user : true`. A new sign-in produces a new
key and triggers a fresh fetch; no anonymous fetch is cached.
- When the token transitions from null to a value, walk the DOM once
and update src on every <img>/<video> pointing at /api/v1/ without
the current token so already-rendered pages reload in place.
- Mirror the query key/gate in CameraPage so it shares the cache entry.
The DOM-rewrite logic is extracted into rewriteMediaSrcWithToken() with
unit tests covering: appending to a query-less URL, & separator with an
existing query, skipping URLs that already carry the current token,
replacing a stale token (trailing and middle positions), leaving
non-/api/v1/ URLs alone, updating <video>, and URL-encoding tokens with
special characters.
The Printer tab AMS popup and spool auto-provisioner resolved color
names from hardcoded tray_id_name tables with a suffix-code fallback —
and suffix codes like "R1" are not globally unique across material
families. A17-R1 (PLA Translucent Cherry Pink) fell through the
fallback and resolved to "Scarlet Red" (A01-R1, PLA Matte), baking
the wrong name into auto-created inventory spools.
The fix removes the hardcoded tables entirely. Backend resolves color
names via the existing color_catalog table by hex; frontend fetches a
compact {hex: name} map once per session via a new
GET /inventory/colors/map endpoint (auth-gated but not on
inventory:read — read-only views need it too) and stores it in a
ColorCatalogProvider context. A useSyncExternalStore hook cascades a
re-render into pages mounted before the fetch completes so they
refresh from HSL-fallback names once the catalog loads.
Existing auto-provisioned spools keep their stored names; only new
provisioning and live display benefit. Co-Authored-By is intentionally
omitted here per project convention — set it via git config if needed.
Spool CRUD endpoints (create, bulk create, update, delete, archive,
restore) did not emit websocket events, so SpoolBuddy Dashboard and
other tabs relying on event-driven cache invalidation never refreshed.
All inventory mutation endpoints now broadcast an `inventory_changed`
websocket event. Frontend handles it by invalidating `inventory-spools`.
Stream tokens are stored in-memory and lost on restart. The frontend
cached the old token for up to 50 minutes (staleTime) and never
refetched, so all thumbnail/stream requests failed with 401 until
a manual page reload.
Added a global error listener in useStreamTokenSync that detects
when img/video elements fail to load with the current stream token
and automatically invalidates the camera-stream-token query to
fetch a fresh one. Debounced with a 5s cooldown to avoid spamming
when many images fail at once.
When multiple AMS spools match the same type/color criteria, an optional
setting now prefers the spool with the lowest remaining filament. This
helps consume partial spools before starting new ones. Sorting applies
to all matching paths: queue scheduler, print modal, and multi-printer
mapping. Unknown remain values (-1) sort to end.
Camera streams, snapshots, thumbnails, timelapse videos, photos, QR
codes, and cover images served via <img>/<video> tags were previously
unauthenticated because browser media elements cannot send Authorization
headers. When auth is enabled, these endpoints are now protected by a
reusable stream token (?token=xxx) obtained from POST
/printers/camera/stream-token (requires CAMERA_VIEW permission).
Assigning or unassigning a spool now broadcasts a spool_assignment_changed
event to all connected WebSocket clients. The frontend handles this event
by invalidating the spool-assignments and slotPresets caches, so other
open tabs update automatically without a page reload.
After an SSH update completed, the UI kept showing "Update complete,
daemon restarting..." and the old "update available" banner because
nothing cleared the stale state. Registration now resets update_status
when the daemon comes back, and WebSocket handlers for spoolbuddy_update
and spoolbuddy_online invalidate the frontend queries immediately.
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.
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 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.

Dual-nozzle H2D/H2D Pro: filament matching now respects nozzle assignments
from the 3MF file. Each AMS unit feeds a specific nozzle (L/R), and the
scheduler/frontend constrain matching to only trays on the correct nozzle.
Falls back to unfiltered matching when no trays exist on the target nozzle.
L/R badges shown in the filament mapping UI. Translated in en/de/ja/it.
Fix AMS slot config overwritten on startup: on_ams_change unconditionally
unlinked BL spool assignments on every MQTT pushall, then re-assigned them
sending ams_filament_setting without setting_id — clearing the printer's
filament preset. Now compares spool RFID identifiers before unlinking.
Fix BL spool detection false positives: removed tray_info_idx from detection
logic in both backend is_bambu_lab_spool() and frontend isBambuLabSpool().
Third-party spools using Bambu generic presets had GF-prefixed tray_info_idx
values, causing misidentification. Now uses only tray_uuid and tag_uid.
SQLite WAL mode with 5s busy timeout reduces "database is locked" errors.
The tray_info_idx field is a filament TYPE identifier (e.g., "GFA00" for
generic PLA), not unique per spool. When multiple AMS trays are loaded
with the same filament type, the previous code used find() which always
returned the first match regardless of color.
Now checks if tray_info_idx is unique among available trays:
- If unique: use that tray as definitive match (existing behavior)
- If not unique: fall back to color matching among matching trays
Fixed in both backend (print_scheduler.py) and frontend (useFilamentMapping.ts).
