Slicer protocol handlers (bambustudio://, orcaslicer://) launch the
slicer app which fetches files via HTTP but cannot send auth headers.
The global auth middleware returned 401, causing "importing failed."
Add short-lived, single-use download tokens: the frontend fetches a
token via authenticated POST, then builds a /dl/{token}/{filename} URL
the slicer can access without auth headers. Tokens are validated
server-side (5-min expiry, single-use). Applies to archive files,
source 3MFs, and library files.
Also fix platform-specific URL formats to match slicer source code:
- macOS: bambustudioopen:// with encodeURIComponent
- Windows/Linux: bambustudio://open?file= (was wrongly using macOS scheme on Linux)
- OrcaSlicer: orcaslicer://open?file=
The spool add/edit modal allowed saving without brand or subtype,
causing incomplete tray_sub_brands when assigned to AMS slots.
BambuStudio then failed to recognize the filament profile.
Brand and Subtype are now mandatory with validation errors on submit.
The /filaments/ endpoint manages material type definitions (cost, temps,
density) but shares its name with the UI's "Filament" page which shows
the spool inventory (/inventory/spools/). This caused users to expect
the API to return their spool inventory.
Rename to /filament-catalog/ to make the distinction clear. No frontend
behavior change — these API methods are defined but unused in the UI.
After clicking "Clear Plate & Start Next", refreshing the page showed
the button again because the frontend determined the state purely from
the printer's FINISH/FAILED status. The backend already tracked a
plate_cleared flag in memory but never exposed it to the frontend.
- Add plate_cleared field to PrinterStatus schema and API response
- Pass plateCleared prop to PrinterQueueWidget
- Skip clear plate UI when plate is already acknowledged
- Add 2 tests for plateCleared=true behavior
When the auto-scan attached the wrong timelapse (e.g. from a different
print), there was no way to fix it — the file couldn't be removed and
re-scanning was disabled once a timelapse was attached.
Three fixes for inventory spool usage not updating after prints:
1. Store ams_mapping from print command (reprint, library print, queue)
so the usage tracker maps 3MF slots to the actual physical trays
the user selected, not the default slicer mapping.
2. Track last_loaded_tray on printer state — the last valid tray_now
(0-253) seen during printing. On H2D printers, tray_now is always
255 in AMS data; the real tray resolves via snow field ~44s after
print start but reverts to "unloaded" at completion. The fallback
chain is: tray_now_at_start > current tray_now > last_loaded_tray.
3. Use color similarity (Euclidean RGB distance, threshold 50) instead
of exact hex match for auto-unlink fingerprint checks. RFID sensors
report slightly different shades across reads (e.g. distance ~43.6
for the same spool), causing false assignment unlinks after prints.
The "Next in queue" widget on the printer card only checked
archive_name/archive_id, so file-manager-sourced queue items
displayed "Archive #null". Now falls back to library_file_name
and library_file_id, matching the Queue page display logic.
Add a "Clear Errors" button to the HMS error modal that sends
clean_print_error via MQTT and locally clears hms_errors for
immediate UI feedback. Useful for dismissing stale print_error
values that persist after print cancellation or transient events.
The small 208px image panel in the skip objects modal made it hard to
distinguish object markers when parts are close together. Clicking the
image now opens a fullscreen lightbox overlay (up to 600px) with the
same markers at a proportionally smaller size, solving the overlap
problem. Close via X button, Escape key, or backdrop click. Escape
cascades correctly — closes lightbox first, then the modal.
When scheduling a multi-plate file from the file manager, the modal
allowed submission without selecting a plate. Now auto-selects the
first plate by default and enforces plate selection for both archive
and library files.
Add scrollbar-gutter: stable to spool form modal to prevent scrollbar
layout thrashing on Windows Edge at non-default zoom levels.
Delete uploaded .3mf from printer SD card root after print completion
to prevent phantom prints on power cycle (reported on P1S).
Three bugs fixed and one recovery feature added:
1. AMS remain=0 zeroed all spools on printer power-off. The weight sync
treated 0% remain as "fully consumed," setting weight_used to
label_weight for every assigned spool. Fix: skip remain=0 in AMS
weight sync — empty spools are tracked by the usage tracker.
2. Editing any spool field sent stale weight_used from the React Query
cache back to the server, resetting usage-tracked weight. Fix: only
include weight_used in PATCH when the user explicitly changes it.
3. K-profile auto-select crashed on dual-nozzle printers for non-BL
spools with 'SpoolKProfile has no attribute extruder_id'. The model
attribute is 'extruder', not 'extruder_id'.
4. New "Sync Weights from AMS" button in Settings > Filament Tracking
(built-in inventory mode) to force-recover spool weights from live
AMS sensor data. Bypasses the "only increase" guard for explicit
user-initiated recovery.
When editing a spool (changing note, color, etc.), the form always sent
weight_used back to the server. If the React Query cache held a stale
pre-print value, saving would silently reset remaining weight to full.
Track whether the user explicitly touched the weight field and only
include weight_used in the PATCH request when creating a new spool or
when the weight was intentionally changed.
Add a chronological, table-based print log as a 4th view mode in the
Archives page. Log entries are stored in a separate print_log_entries
table — clearing the log never touches archives or queue items.
Backend:
- New PrintLogEntry model with independent table
- GET /print-log/ endpoint with search, printer, user, status, date filters
- DELETE /print-log/ clears only log entries
- Thumbnail serving endpoint for log entries
- write_log_entry() service called on print completion
- Auth: ARCHIVES_READ for viewing, ARCHIVES_DELETE_ALL for clearing
Frontend:
- New 'log' ViewMode with ClipboardList icon toggle
- Filterable/searchable table with pagination (10/25/50/100 rows)
- Colored status badges, duration formatting, filament color swatches
- Clear button with confirmation modal
- All filter state persisted to localStorage
- i18n: EN, DE, JA, FR, IT translations
Notify users when the print bed cools below a configurable threshold
(default 35°C) after a print finishes, so they know when to remove parts.
- Backend: DB migration, model, schemas, notification template, service
method, background cooldown monitor (polls every 15s, 30min timeout)
- Frontend: event toggle in provider card/modal, threshold setting in
Settings > Notifications, i18n keys for all 5 locales
- Tests: 4 backend + 4 frontend tests
- Docs: README, website, wiki updated
When a print is sent from an external slicer and Bambuddy can't
download the 3MF during auto-archiving, the fallback archive has no
file. Reprinting such archives tried to upload the data directory,
causing a confusing SD card error. Backend now returns a clear 404
for empty file_path and checks is_file() instead of exists(). Frontend
disables Print/Schedule/Open in Slicer for file-less archives with an
explanatory tooltip. Added i18n key in all 5 locales.
Backend /updates/check endpoint now returns early without calling
GitHub API when check_updates is disabled. Settings page no longer
auto-fetches update status when the setting is off. Printer card
firmware badge falls back to showing the current version from MQTT
instead of disappearing when firmware update checks are disabled.
Downgrade 58 diagnostic logger.info calls to logger.debug in
bambu_mqtt.py — payload dumps, detector state changes, field
discovery, H2D disambiguation, and periodic status updates no longer
flood logs at the default INFO level. User-initiated actions (print,
stop, calibration, AMS load/unload) remain at INFO. Also suppress
paho-mqtt library INFO messages in production mode.
The archive grid view displayed a red status badge for failed and
aborted prints, but the list view had no equivalent indicator. Added
an inline badge next to the print name in ArchiveListRow, reusing the
existing i18n keys and status-error styling from the grid view.
When enabling Spoolman, stale built-in inventory slot assignments
persisted in the database and the printer card UI still showed
assign/unassign buttons from the internal inventory. Now bulk-deletes
all SpoolAssignment records on mode switch, invalidates the frontend
spool-assignments cache, and hides inventory UI on printer cards while
Spoolman is active.
- Replace browser confirm() with styled ConfirmModal for inventory
delete (danger) and archive (warning) actions
- Expand default color catalog from 258 to 638 entries (6 → 20 brands)
with measured hex codes from FilamentColors.xyz
- Expand eSUN from 10 generic placeholders to 79 measured colors
across 10 material lines
- Add built-in inventory note about third-party spool assignment
- Increase Spool/Color Catalog settings card height (400px → 600px)
- Add i18n keys for all new strings (en, de, fr, it, ja)
- Update wiki inventory docs with catalog management details
The color pre-population logic skipped hex 000000 (black) to guard
against empty/uninitialized slots, but empty slots already don't pass
trayColor to the modal. Removed the unnecessary check so black filament
color is now pre-populated like any other color.
Backend:
- Add dual external spool support for H2D (vt_tray as list: Ext-L/Ext-R)
- Add cloud filament ID map endpoint (/cloud/filament-id-map)
- Fix RFID spool data erased by periodic AMS updates (skip tag matcher
for RFID-tagged trays)
- Fix AMS slot config overwrites RFID spool state
- Fix K-profile selection corrupts existing profiles on X1C/P1S
- Resolve K-profiles filament name via cloud filament ID map
- Update print scheduler and usage tracker for dual external spools
Frontend:
- Add printer model filtering to ConfigureAmsSlotModal (cloud/local/builtin
presets filtered by @BBL model suffix and compatible_printers)
- Add pre-population for configured slots (preset, color, K-profile)
- Add K-Profiles view with accurate filament name resolution
- Internationalize all ConfigureAmsSlotModal strings (en/de/fr/it/ja — 21 keys)
- Add 5 new ConfigureAmsSlotModal tests (model filtering, pre-selection,
color pre-population, i18n)
- Update PrintersPage for dual external spool rendering
Docs:
- Update CHANGELOG, README, website features, and wiki AMS docs
Status summary bar on the Printers page now shows availability count
("X available") and a "Next available" indicator with printer name,
progress bar, percentage, and remaining time for the printer finishing
soonest. Always visible when printers are printing; hidden otherwise.
Fix race condition in bulk archive deletion where files were removed
from disk before the database commit. Concurrent SQLite writes could
cause a lock timeout, rolling back the DB delete while files were
already gone — leaving orphaned records with broken thumbnails. Now
deletes the DB record first and only removes files after a successful
commit.
H2/A1 series have linear rails, not carbon rods. X1/P1/P2S have carbon
rods, not linear rails. Split rod-specific maintenance into model-aware
pairs: "Lubricate/Clean Carbon Rods" for X1/P1/P2S and "Lubricate/Clean
Linear Rails" for A1/H2. Added rod type classification to printer_models
and startup cleanup for stale/duplicate system maintenance types.
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.
Prevent accidentally skipping the wrong object during a print by showing
a warning confirmation dialog with the object name and an irreversible
action warning. Uses the existing ConfirmModal component with warning
variant. Translations added for all 4 locales (en, de, ja, it).
The print scheduler previously treated FINISH/FAILED as idle states
and would auto-start the next queued print before the user cleared
the build plate. Now requires explicit user confirmation via a
"Clear Plate & Start Next" button on the printer card. Uses an
in-memory plate-cleared flag — no MQTT command needed since the
scheduler's start_print overrides the printer state.
External links behind reverse proxies (Traefik, nginx) block iframe
embedding via X-Frame-Options/CSP headers. Add a per-link boolean
toggle so users can choose between iframe (default) and new-tab
behavior. Keyboard shortcuts also respect the setting.
The cover image URL was always /printers/{id}/cover regardless of the
active print, so the browser served its cached image. Now appends the
print name as a cache-busting query parameter and resets load state
when the print changes.
Content-Disposition parser now handles RFC 5987 percent-encoded filenames
(filename*=utf-8''...) used by FastAPI for non-ASCII characters. Applied
to all 7 download endpoints.
Closes#334
Rename the "Users" settings tab to "Authentication" and move the
standalone "Global Email" tab into it as an "Email Authentication"
sub-tab. This groups email/SMTP configuration with user management
where it logically belongs.
- Remove top-level email tab from settings tab bar
- Add sub-tab navigation (Users / Email Authentication) inside the
Authentication tab
- Handle legacy ?tab=email URLs by mapping to users tab + email sub-tab
- Update i18n keys in en/de/ja locales
