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 H2C dual nozzle variant reports model code O1C2 via MQTT, but only
O1C was recognized. This caused the camera to use the wrong protocol
(chamber image on port 6000 instead of RTSP on port 322), producing a
reconnect loop. Added O1C2 to all model ID maps across 8 files.
The purple queue counter badge in the printer card header used the raw
unfiltered queue item count, so it appeared on ALL printers of the same
model when a job was scheduled for "any [model]" — even printers without
the matching filament color. The PrinterQueueWidget below it (which
shows "Clear Plate & Start") already filtered by filament type + color.
Apply the same filament compatibility filter (type check + color override
check) to the badge count so it only shows on printers that can actually
run the queued jobs.
When a print was queued to "any printer" with a filament color override
(e.g., white PETG), the "Clear Plate & Start Next" button appeared on
printers that had the right type but wrong color. The backend scheduler
already rejected color mismatches, but the frontend only checked filament
types. Now passes loaded type+color pairs from AMS status to the widget
and filters against filament_overrides, mirroring the backend's
_count_override_color_matches() logic.
The "Clear Plate & Start Next" button appeared on ALL printers of a
model when a job was queued via "Queue to Any X", even printers without
the required filament loaded. Clicking it started a print that fails.
PrinterQueueWidget now filters queue items by filament compatibility —
each item's required_filament_types must all be present in the printer's
loaded filaments (AMS + external spools). If no compatible items exist,
the widget is hidden entirely. Matching is type-only (not color) and
case-insensitive, consistent with the backend scheduler. When filament
data is unavailable, no filtering is applied (graceful degradation).
Virtual printer "print_queue" mode created queue items with no printer
assignment. Now sets target_model from the VP's SSDP model code (e.g.
P1S, X1C) for "Any Printer" scheduling, or uses target_printer_id if
configured.
Settings page auto-save onSuccess overwrote localSettings with the
server response, discarding characters typed during the save request.
Removed the stale state overwrite so in-progress input is preserved.
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.
The "Power off printer when done" checkbox in the print modal and the
auto power off tri-state toggle in the bulk edit modal were accessible
to all users regardless of permissions. Users without printers:control
can now no longer enable auto power off — controls are disabled and
visually dimmed.
Three related fixes in PrintersPage.tsx:
1. External spool (vt_tray) fill level was missing the AMS remain
fallback — only checked Spoolman/inventory, ignoring valid AMS data.
Now uses the same fallback chain as regular and AMS-HT slots.
2. When fill was unknown (null), slot visual showed a full-width gray
bar ("full") while the hover card showed "—" ("empty"). Removed the
misleading gray fallback bar from all three slot types so both views
consistently show "unknown".
3. Fill source priority always preferred AMS remain over Spoolman and
inventory, even when those sources were more accurate (e.g. spools
with usage tracking or migrated from Spoolman). Reversed priority to
Spoolman → Inventory → AMS remain. Fixed fillSource label to reflect
the actual data source (was always 'ams' even when using fallback).
On H2C/H2D dual-nozzle printers, tray_now=254 is sent generically for both
external spools. The direct ID comparison always matched Ext-L (id=254),
never Ext-R (id=255). Now uses active_extruder to disambiguate: extruder
1 (left) → Ext-L, extruder 0 (right) → Ext-R.
Previously the Inventory sidebar item was hidden when Spoolman was
enabled. Now it always shows — when Spoolman is active, /inventory
embeds the Spoolman web UI in the content area via iframe; when
disabled, it renders the internal inventory page as before.
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).
Group toggle in inventory toolbar collapses identical unused/unassigned
spools into expandable rows/cards with count badges. Grouping key uses
material, subtype, brand, color, and label weight. Brand and subtype
fields now appear in quick-add mode as optional (no asterisk, no
validation). Quantity field restricted to quick-add mode only.
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)

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)

Two bugs in the inventory page:
1. Dates always displayed as DD/MM/YY regardless of the user's date
format setting. The page had a local formatDate() hardcoding en-GB
locale. Replaced with the shared formatDateOnly() from utils/date.ts.
2. AMS-HT slot locations showed accented characters (e.g., "Á1") instead
of proper labels (e.g., "HT-A"). The code used String.fromCharCode(65
+ ams_id), which produces garbled chars for AMS-HT IDs (128+). Now
uses the shared formatSlotLabel() from utils/amsHelpers.ts.
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.
BambuStudio actively resets AMS slots configured with unrecognized PFUS*
(user-local) preset IDs. Replace PFUS* with generic Bambu filament IDs
(e.g. GFL99 for PLA) in both the slot configure and inventory assignment
endpoints. When the slot already has a recognized cloud-synced preset for
the same material, reuse it to preserve K-profile calibration.
Also fix fill level bar not showing for brand new spools (weight_used=0)
by changing the condition from weight_used > 0 to weight_used != null.

The printer only sends PAUSE via MQTT gcode_state, never PAUSED.
Removed all unreachable PAUSED comparisons from frontend (4 files)
and backend (2 files).
Add a new `printers:clear_plate` permission so admins can grant
plate-clearing ability without full `printers:control` access.
Existing groups with `printers:control` automatically receive the
new permission on startup via migration.
Replace the cramped permission modal in Settings with a dedicated
full-page group editor (`/groups/new`, `/groups/:id/edit`) featuring
search filtering, select all/clear all, category-level toggles,
and a responsive 2-column permission grid. Remove dead GroupsPage
code that was never routed.
- Backend: new Permission enum, category, defaults, endpoint guard, migration
- Frontend: GroupEditPage, updated routes, removed modal from SettingsPage
- Tests: 10 backend + 10 frontend tests for new permission and editor
- Docs: updated wiki (auth, printer-control, API), website, changelog
- i18n: added group editor keys to all 6 locale files (en/de/ja/fr/pt-BR/it)
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.
