Reporter saw a 544 g spool jump to 1000 g after pressing the eraser.
"Spools and remaining weights are not changed" - the dialog promised
this; the implementation did the opposite. Root cause was an
architectural conflation: `weight_used` did double duty as the
resettable "consumed since tracking started" counter AND as the basis
for the displayed remaining (`label_weight - weight_used`), so zeroing
it correctly cleared the stat but unavoidably reset remaining to full.
Spoolman has separate `used_weight` and `remaining_weight` fields, so
the API call there was correct - but Bambuddy's frontend was also
computing remaining as `label_weight - weight_used` for Spoolman
spools (ignoring Spoolman's real `remaining_weight` field), so the
same visual bug bit there too. Inventory-mode parity required fixing
both halves in one drop.
Internal mode
- New `weight_used_baseline` column (Float DEFAULT 0) on `spool`.
- Reset stamps `baseline = weight_used` and leaves `weight_used` alone.
- Displayed consumed = `weight_used - baseline`; remaining =
`label_weight - weight_used` (unchanged).
- Subsequent prints continue to grow `weight_used`, so the resettable
counter naturally tracks post-reset delta and remaining keeps
decrementing across the reset.
Spoolman mode
- `_map_spoolman_spool` now reads Spoolman's `remaining_weight` field
and returns a synthetic `weight_used = label - remaining` so the
frontend's remaining calc matches Spoolman's real stored value;
`weight_used_baseline = synthetic - real_used_weight` so the consumed
counter (`weight_used - baseline`) matches Spoolman's `used_weight`.
- Fallback path (no `remaining_weight` set) preserves the old behavior.
- Related fix: `update_spool` (Spoolman PATCH) was deriving the default
`weight_used` from `used_weight`, so editing unrelated fields AFTER
a reset would patch Spoolman with `remaining_weight = label - 0 =
label`, trampling the real value. Now derives from
`remaining_weight` so non-weight edits preserve physical state.
Frontend
- `InventoryPage` `totalConsumed` aggregate switched to
`Math.max(0, weight_used - (weight_used_baseline ?? 0))`.
- `ForecastPanel` `computeDeltaRate`, `totalUsedG`, and the per-spool
"consumed" table cell got the same treatment so forecast and
inventory aggregates stay coherent across a reset.
- `?? 0` keeps pre-migration installs rendering correctly until
`init_db()` runs the idempotent ALTER TABLE.
Migration
- `ALTER TABLE spool ADD COLUMN weight_used_baseline REAL DEFAULT 0`
via `_safe_execute` - SQLite and Postgres both accept it; verified
end-to-end on Postgres 16.
The column existed on the Spool ORM model but was missing from
SpoolBase, SpoolUpdate, and SpoolResponse. Pydantic silently
dropped writes and reads omitted the field, so the inventory
table always showed "—" in the Storage Location column even
after saving. Adding the field to the two schemas is enough —
the update route already uses model_dump + setattr.
The SpoolBuddy "weigh-then-assign" workflow tried to configure an empty AMS
slot at assign time, but Bambu firmware silently drops ams_filament_setting
and extrusion_cali_sel for unloaded slots — the MQTT calls completed and the
modal closed, yet BambuStudio kept showing the slot as default-PLA forever.
assign_spool now detects an empty target slot (fingerprint_type empty) and
persists the SpoolAssignment without publishing MQTT, returning a new
pending_config flag so the frontend can swap "Assigned!" for "Slot will
configure when you insert the spool." on_ams_change watches for the slot
to load (state == 11, which fires for 3rd-party tags too even when
tray_type stays empty) and replays the deferred ams_filament_setting +
extrusion_cali_sel — including the printer-kp realignment that converts
PFUS-prefix cloud user presets to the P-prefix local-preset filament_id
the slicer actually accepts.
The full assign-time MQTT block was extracted into
apply_spool_to_slot_via_mqtt so both the assign endpoint and the
on_ams_change replay path use the same resolution logic; the helper takes
~270 lines of duplication out of assign_spool.
Spool and color_catalog rows carry extra_colors (comma-separated hex
stops) and effect_type (14 visual variants: surface effects, sheen,
structural). The shared FilamentSwatch component renders gradient,
conic, effect overlay, and alpha-checkerboard consistently across the
inventory grid, table, group banner, card, ColorSection preview, and
catalog editor. Catalog hex_color accepts #RRGGBBAA so catalog entries
can carry transparency too.
The paste field accepts the exact format 3dfilamentprofiles.com puts on
its filament details pages, so users can copy a multi-colour combo
directly. The effect dropdown spans the full filament-variant
vocabulary -- surface effects (sparkle/wood/marble/glow/matte), sheen
variants (silk/galaxy/rainbow/metal/translucent), and structural
variants (gradient/dual-color/tri-color/multicolor). None of these
fields touch MQTT/firmware -- pure visual hint.
Spool group-key extended to include extra_colors + effect_type so
"Group similar" no longer collapses visually distinct spools.
Migrations: 4 idempotent ALTER TABLE ADD COLUMN (Postgres-safe), plus
ALTER COLUMN hex_color TYPE VARCHAR(9) on Postgres only (SQLite ignores
VARCHAR length).
Tests: 42 new backend (35 unit + 7 integration), 20 new frontend (14
FilamentSwatch + 3 ColorCatalogSettings + 3 InventoryPageGrouping
regression). 3522 backend + 1582 frontend tests pass; ruff clean.
Localised across all 8 UI locales.
Two new optional fields on Spool: free-text `category` (max 50) and
`low_stock_threshold_pct` (1-99). Powers the "differentiate critical
spools from prototype spools and alert at different thresholds" use
case from #729 without taking on the full multi-tag taxonomy + auto-
apply rules + per-tag alert system the ticket originally proposed.
Form gains:
- Category input with datalist autocomplete sourced from categories
already in use, so casing/spelling stays consistent.
- Per-spool low-stock threshold input. Empty = global default; the
global value renders as the placeholder.
Inventory page:
- New category filter chip (hidden until at least one spool carries
a category — keeps the chip row uncluttered).
- Stat-card "Low Stock" count and the "Low Stock" filter both honour
the per-spool override.
Plus: rename "Delete Tag" button to "Clear RFID Tag" (the original
ticket reporter mistook it for a taxonomy-tag delete; the button
actually clears the RFID UID/UUID off the spool record). Toast key
renamed from `tagDeleted` to `rfidCleared`.
i18n: full translations across all 8 locales.
Tests: 9 new backend schema tests (defaults, partial-update, range
rejection, max-length); 2 new frontend tests (per-spool threshold
pulls extra spools into low-stock count, filter chip hidden when no
categories exist).
feat(inventory): replace Spoolman iframe with internal inventory UI
When Spoolman is enabled, the Inventory page now uses the same internal
UI (spool list, create/edit modal, archive, delete, weight sync) backed
by a new proxy layer instead of opening an iframe.
A single legacy spool with a 7-char rgba ('FFFFFFF', missing one F)
caused GET /api/v1/inventory/spools to 500 with a pydantic
ResponseValidationError, leaving the reporter with a blank Filaments
page and "Add Spool" silently failing. Root cause spans three layers:
1. Write path: SpoolUpdate.rgba had no pattern constraint (only
SpoolCreate did), so PATCH could plant malformed values in the DB.
2. Frontend: ColorSection hex input's `val.length <= 6 ? 'FF' : ''`
emitted 7-char rgba for 5-char input (XXXXX + FF = 7) and for
7-char typed input (no alpha appended).
3. Read path: SpoolResponse inherited the write-side pattern, so a
single bad row 500'd the entire list endpoint instead of being
tolerated through serialize.
SpoolUpdate.rgba now carries the same ^[0-9A-Fa-f]{8}$ pattern as
SpoolCreate. The hex input emits a fully-formed 8-char RRGGBBAA on
every keystroke — 8-char paste passes through, 7-char drops the
stray, shorter input pads RGB with '0' and appends FF alpha.
SpoolResponse.rgba is now Optional[str] with no pattern — write-side
validation is the right place for format rules; responses must
tolerate historical rows.
Tests: 16 schema tests (SpoolCreate/Update reject, SpoolResponse
tolerate), 7 frontend tests covering every input length 0–8 plus
non-hex strip. A user who already has a bad row in their DB now sees
it render with a default color instead of having to hand-edit SQLite.

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.
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.
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)
