The 7cb905a follow-up mounted the global unknown-tag modal listener, which
turned an existing always-on broadcast for no-tag slots from a silent no-op
into a perpetual popup loop — every push for a slot with a generic
non-RFID spool (or zero-filled tag) re-prompted, and confirming each one
created a fresh ghost spool with an empty tag.
- main.py on_ams_change: drop the no-tag else-branch broadcast. No identity,
no prompt; the slot stays unassigned until a real tag is read.
- inventory.py + spoolman.py /spools/from-slot: 400 when the slot has no
usable tag_uid / tray_uuid so stale frontends can't recreate the ghost
spool by re-confirming a queued prompt.
- test_inventory_from_slot_no_tag: lock the guard in (zero-filled + empty
string).
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.
GET /spoolman/spools/unlinked hid any spool with a non-empty
extra.tag from the AMS-slot assignment picker. extra.tag is only an
RFID/NFC matching key -- OpenSpoolman writes its own NFC tag value
into that same Spoolman field -- so every OpenSpoolman-tagged spool
became un-assignable in Bambuddy even when it occupied no slot.
get_unlinked_spools now determines assignability from the
spoolman_slot_assignments table (the documented source of truth for
slot assignments) and ignores extra.tag entirely. Both link_spool and
the AMS auto-sync upsert a row there for every occupied slot, so the
ledger is complete. get_linked_spools and find_spool_by_tag still use
extra.tag -- they are genuine tag-match maps and are unaffected.
Internal-inventory mode needs no parallel change: it stores tags in
its own DB with no Spoolman extra collision.
Updates test_get_unlinked_spools_success and adds
test_get_unlinked_spools_excludes_slot_assigned.
Reporter on a P1S with non-RFID spools saw an old, almost-empty spool in
the AMS hover card's "Spulen-ID" block while the "Zugewiesen" block
correctly showed the freshly assigned full spool. Two layers compounded:
(1) Non-RFID slots fall back to a deterministic per-slot tag
(hash(serial) + ams_id + tray_id). The Link / Assign routes wrote
that tag to Spoolman extra.tag but never cleared it from the
previous holder on re-binding.
(2) The frontend's hover-card resolver preferred the (stale) tag-link
over the user's explicit slot-assignment. Same precedence bug in
SpoolBuddy's fill-bar resolver and slot-action picker.
Frontend: swap precedence at 5 sites — slot-assignment outranks tag-link
everywhere. FilamentHoverCard's existing match-dedupe then collapses the
two "Open in Inventory" buttons back into one.
Backend: new _clear_stale_tag_links() in spoolman_inventory.py, called
from POST /spoolman/inventory/slot-assignments (with the slot's
deterministic fallback tag) and POST /spoolman/spools/{id}/link (with
the literal tag being bound — works for RFID and fallback). Best-effort:
Spoolman 5xx and per-spool patch failures log + continue, never wedge
the bind. get_fallback_spool_tag_for_slot promoted to a public helper
mirroring the frontend's signature exactly.
Spoolman had two mutually-exclusive weight paths gated on the
`disable_weight_sync` flag. The default (False) used AMS remain%
x tray_weight auto-sync, which silently dropped non-BL spools
because the AMS doesn't report tray_weight without RFID. The
inventory_remaining fallback would have covered it, but the
spool_assignment table it reads from is wiped on Spoolman
activation, so non-BL spools got no weight updates at all.
Match the internal Filament Inventory: per-print tracking always
runs, AMS auto-sync no longer writes remaining_weight (it still
maintains spool metadata and slot assignments). The setting
becomes a no-op; left in the schema and UI for backwards compat.
- store_print_data: drop the disable_weight_sync early return
- sync_ams_tray callsites in main.py + routes/spoolman.py: force
disable_weight_sync=True so weight is never written by AMS sync
- new regression test confirming tracking runs with flag=false

* Add filament_vendor field to UnlinkedSpool model and populate from API response
* Add filament_vendor field to UnlinkedSpool interface
* Enhance LinkSpoolModal to include filament_vendor in search and display
The on_ams_change auto-sync callback set locations for new spools but
never called clear_location_for_removed_spools(), leaving stale locations
that caused double-booked slots. Also pass synced_spool_ids in the
single-printer sync route to match the sync-all endpoint behavior.
* Enhance link spool functionality with additional printer and AMS details
* Refactor linkSpool function to accept detailed context object for improved spooling integration
* Enhance LinkSpoolModal to include amsName in props and linkSpool mutation for improved functionality
* Add amsName prop to PrinterCard for enhanced spool linking functionality
* 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
* Remove amsName from LinkSpoolModal and PrinterCard for cleaner API integration
* Remove amsName from LinkSpoolModal test props and update linkSpool mock response for improved clarity
* 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

AMS Lite units (A1 series) have no weight sensor and always report 0%
fill level. When a spool is linked to Spoolman with weight data, use
Spoolman's remaining weight as a fallback. External spools also show
fill level from Spoolman data instead of always showing unknown.
Backend: Enrich GET /spoolman/spools/linked response with
remaining_weight and filament_weight alongside spool ID.
Frontend: Add getSpoolmanFillLevel() helper. Update regular AMS, HT
AMS, and external spool fill computations to use Spoolman fallback
when AMS reports 0%. Show "(Spoolman)" indicator in hover card when
fill data comes from Spoolman.
Implements retry mechanism to handle intermittent network errors when
fetching spools cache for AMS sync operations.
Changes:
- Add retry logic to get_spools() with 3 attempts and 500ms delay
- Configure httpx client with connection pool limits to prevent stale
connection reuse (max_keepalive_connections=5, keepalive_expiry=30s)
- Recreate client on connection errors (ReadError, RemoteProtocolError)
- Abort sync operations if cache fetch fails after all retries
- Update on_ams_change, sync_single_printer, and sync_all_printers to
handle cache fetch failures gracefully
This addresses ReadError(ClosedResourceError()) failures that occurred
intermittently when Spoolman closed idle connections or connection
pooling reused stale connections.
Testing:
- Added 4 new unit tests for retry behavior
- All 1018 tests passing
- Add cached_spools parameter to find_spool_by_tag, find_spools_by_location_prefix, sync_ams_tray, and clear_location_for_removed_spools
- Fetch spools once before loops in on_ams_change, sync_single_printer, and sync_all_printers endpoints
- Cache newly created spools during sync to avoid duplicate API calls
- Add 5 unit tests for caching functionality (all passing)
- Reduce redundant API calls when syncing multiple AMS trays
- Improve sync performance for users with large spool databases
- Maintain backward compatibility with optional cached_spools parameters
Implement accurate per-filament usage tracking for Spoolman integration,
similar to OpenSpoolman v0.3.0. This replaces the previous single-spool
reporting with multi-material aware tracking.
Features:
- Parse G-code from 3MF files at print start to build per-layer,
per-filament cumulative extrusion maps
- Store tracking data in new `active_print_spoolman` database table
(survives server restarts for long prints)
- Report accurate partial usage when prints fail/cancel based on
actual layer progress and G-code data
- Add "Disable AMS Weight Sync" setting to prevent AMS percentage-based
weight estimates from overwriting Spoolman's granular tracking
- Add "Report Partial Usage for Failed Prints" toggle (only shown when
weight sync is disabled)
- Use Spoolman's filament density instead of defaults for mm-to-grams
conversion
- Prefer tray_uuid over tag_uid for spool identification
When a spool is already linked in Spoolman, the FilamentHoverCard now shows
"Open in Spoolman" button instead of "Link to Spoolman". This allows users
to quickly navigate to the spool's page in Spoolman for editing.
Changes:
- Add GET /api/v1/spoolman/spools/linked endpoint returning tag->spool_id map
- FilamentHoverCard shows "Open in Spoolman" when linkedSpoolId is set
- "Link to Spoolman" only shows when spool is not linked
- Fix unlinked spools detection to strip JSON quotes from empty tags
- Add toast notifications for link success/failure
- Invalidate linked-spools query after linking
- Add backend tests for linked spools endpoint
- Add frontend tests for LinkSpoolModal
Closes#210
The 'tag' extra field is required in Spoolman for storing RFID/UUID
identifiers that link Bambu Lab spools to Spoolman entries. Previously,
users had to manually create this field in Spoolman, causing sync
failures for fresh installations.
Added ensure_tag_extra_field() method to SpoolmanClient that:
- Checks if the 'tag' field exists via GET /api/v1/field/spool/tag
- Creates it via POST if missing
The method is called automatically:
- On app startup when auto-connecting to Spoolman
- When user clicks "Connect" in Spoolman settings
The spool detection only checked tray_uuid and tag_uid, but some Bambu Lab
spools have RFID read issues causing these to be missing while still having
valid tray_info_idx (Bambu filament preset ID like "GFA00").
Backend changes (backend/app/services/spoolman.py):
- Add tray_info_idx to AMSTray dataclass
- Parse tray_info_idx from raw MQTT data in parse_ams_tray()
- Check tray_info_idx first in is_bambu_lab_spool() - most reliable indicator
- Bambu Lab presets start with "GF" (GFA00, GFB00, GFL00, etc.)
- Fall back to tray_uuid then tag_uid for unique spool identification
- Add warning when Bambu spool detected but no unique ID for Spoolman
Backend changes (backend/app/api/routes/spoolman.py):
- Update /sync/{printer_id} and /sync-all to pass tray_info_idx
- Guard against empty spool_tag when adding to tracking set
Frontend changes (frontend/src/pages/PrintersPage.tsx):
- Add isBambuLabSpool() helper with same detection logic as backend
- Update all 4 vendor detection locations in AMS cards to use new helper
Detection priority (same on frontend and backend):
1. tray_info_idx starts with "GF" (Bambu preset ID)
2. tray_uuid is valid 32-char hex (non-zero)
3. tag_uid is valid 16-char hex (non-zero)
The spool detection logic only checked tray_uuid (32 hex chars) to identify
Bambu Lab spools. Some spools have RFID read issues causing missing or
invalid tray_uuid while still having valid tag_uid (16 hex chars).
Changes:
- Update is_bambu_lab_spool() to accept tag_uid as fallback parameter
- Prefer tray_uuid for identification, fall back to tag_uid if invalid
- Use whichever valid identifier for Spoolman tag storage and matching
- Update both /sync/{printer_id} and /sync-all endpoints
This fixes spools being incorrectly marked as "Non-Bambu Lab spool (no RFID
tag)" when they have valid tag_uid but missing/zero tray_uuid.
Previously, when syncing to Spoolman, the location field was set to the
printer/AMS slot but was never cleared when the spool was removed from
the AMS.
Now during sync, the system tracks which tray UUIDs are currently in the
AMS and clears the location for any spools that were previously at this
printer but are no longer present.
Changes:
- Add clear_location parameter to update_spool() method
- Add find_spools_by_location_prefix() to find spools at a printer
- Add clear_location_for_removed_spools() to clear stale locations
- Update sync_printer_ams and sync_all_printers endpoints to clear
locations for removed spools after syncing
- Link to Spoolman: Manually link existing Spoolman spools to AMS trays
- Hover over AMS slot to see "Link to Spoolman" button
- Select from list of unlinked Spoolman spools
- Automatically sets extra.tag field in Spoolman
- Spool UUID display: View and copy Bambu Lab spool UUID in AMS hover card
- Shows first 8 chars with copy button (full UUID to clipboard)
- Fallback copy method for HTTP contexts
- Sync feedback: Shows synced count and skipped spools with reasons
- Expandable list when more than 5 skipped
- Color swatches for identification
- Fixed Spoolman 400 Bad Request: extra field values must be valid JSON
- Updated documentation (wiki, website)
