- Replace TagDetectedModal with inline SpoolInfoCard/UnknownTagCard
in dashboard right panel (known spools show assign/sync/close,
unknown tags show add-to-inventory/link/close)
- Rewrite AssignToAmsModal as full-screen overlay reusing AmsUnitCard,
with AMS-HT and external slot support, single assignSpool API call
- Remove printer selector from assign modal (uses top bar selection)
- Extract filament_id <-> setting_id conversion to shared utility
(backend/app/utils/filament_ids.py), used by inventory + cloud routes
- Normalize slicer_filament in assign_spool to derive proper
tray_info_idx and setting_id for MQTT (was sending setting_id="")
- Rename SpoolBuddy top bar status label "Online" -> "Backend"
- Remove weightStable guard from sync weight button
The MQTT completion handler stored "aborted" as the queue item status
when a print was cancelled mid-print, but the response schema only
allows "cancelled". Pydantic validation failed on the invalid status
when listing all queue items, returning 500. Filtering by specific
status excluded the bad row so those still worked.
Normalise "aborted" → "cancelled" before storing. A startup fixup
also converts any existing "aborted" rows in the database.
sync_from_db() skipped VPs already in self._instances without checking
if their config had changed. Mode, model, access code, bind IP, remote
interface IP, and target printer changes were silently ignored until
manual toggle off/on or full restart. Now detects config drift and
restarts affected instances.
Four support package improvements:
1. Mask first two octets of subnet IPs in support info
(192.168.1.0/24 → x.x.1.0/24) to avoid leaking private network
addresses.
2. Fix Docker network_mode_hint detection. The old heuristic
(interface count > 2) always reported "bridge" on single-NIC
hosts because get_network_interfaces() excludes Docker
interfaces. Now checks for docker0/br-*/veth* visibility via
socket.if_nameindex() — these are only visible in host mode.
3. Parse MQTT "fun" field at top level of payload (not just inside
"print" key). Some firmware versions send it there, which
explains why developer_mode was null for most users.
4. Add virtual_printers section to support info with mode, model,
enabled/running status, and pending file count.
The Updates card on the Settings page mixed printer firmware and
Bambuddy software update toggles with no visual distinction. Now
groups them into labeled sections ("Printer Firmware" at top,
"Bambuddy Software" below) with a divider between them.
The Python hash verification in start_bambuddy.bat used a multi-line
`for /f "usebackq"` with a backtick-delimited command split across
lines. Windows CMD cannot parse line breaks inside backtick-delimited
for /f commands, causing "The syntax of the command is incorrect" at
step 1/6. Removed the entire redundant verification block — the
verify_sha256 subroutine already checks the archive against the
pinned hash. The removed block also had a secondary bug: it always
downloaded the amd64 checksum from python.org even on arm64 systems.
v0.2.1.1
Just one day ago after the last release, but I decided to make life a little better for those of you guys who are just received their new H2C :)
What happened?
Recent H2C deliveries from Bambu Lab ship with an updated internal model identifier: O1C2 instead of the previously known O1C. Bambuddy only recognized O1C, so these newer H2C units were not properly identified.
Also included some fixes.
- Fix sidebar navigation not respecting user permissions
- Fix camera button permissions & ffmpeg process leak (#550)
- Fix A1 Mini "unknown" status from non-UTF-8 MQTT payload (#549)
- Fix Windows install syntax error from LF line endings (#544)
- Fix queue badge showing on printers without matching filament (#486)
- Fix naive-vs-aware datetime crash from 0.2.1 timezone migration
Sidebar nav items (Archives, Queue, Stats, Profiles, Maintenance,
Projects, Inventory, Files) were visible to all users regardless of
role permissions — only Settings was gated. Now each item is hidden
when the user lacks the corresponding read permission. Printers
remains always visible as the home page.
Also adds missing inventory:read|create|update|delete to the frontend
Permission type (existed in backend but was absent from the frontend
type definition).
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.
Some firmware versions send MQTT payloads with non-UTF-8 bytes.
UnicodeDecodeError was uncaught, silently dropping the entire message
and leaving printer status as "unknown" with 0°C temps and no AMS.
Fall back to decode(errors="replace") to keep JSON parseable.
The start_bambuddy.bat launcher had Unix (LF) line endings. When a
user's git is configured with core.autocrlf=false or input, the file
is checked out with LF endings and cmd.exe fails with "the syntax of
the command is incorrect" before reaching the hash check.
Add .gitattributes forcing CRLF for *.bat files so they always get
correct line endings on checkout regardless of git config.
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.

The tare and calibrate buttons on the Settings page queued commands
but never executed them due to five broken links:
1. Daemon received tare command but never called scale.tare()
2. No endpoint to persist tare offset back to backend DB
3. Heartbeat never called scale.update_calibration()
4. Heartbeat response with stale values overwrote new tare to zero
5. set-factor used DB tare_offset (stale/zero), producing wrong
calibration factor — empty scale showed ~5000g
Fixed daemon to execute tare, persist result, and propagate
calibration. Calibration step now captures raw ADC at tare time
and sends it with step 2, making factor computation self-contained.
Replaced calibration weight input with compact touch numpad for
the RPi kiosk's 1024x600 touchscreen (no physical keyboard).
The tare and calibrate buttons on the Settings page queued commands
but never executed them due to four broken links:
1. Daemon received tare command via heartbeat but never called
scale.tare() — the ScaleReader was available in shared dict
but unused
2. No API endpoint for the daemon to report the new tare offset
back to the backend DB, so tare results were lost
3. Heartbeat updated config but never called
scale.update_calibration(), so ScaleReader kept initial values
4. The heartbeat response delivering the tare command still had
pre-tare values, immediately overwriting the new offset to zero
Added set-tare endpoint + API client method, and fixed heartbeat
loop to execute tare, persist the result, propagate calibration
changes to the ScaleReader, and skip calibration sync on the
heartbeat cycle that delivers a tare command.
Also replaced the calibration weight input with a touch-friendly
numpad since the RPi kiosk has no physical keyboard.

Added set-tare endpoint + API client method, and fixed heartbeat

predates the tare and would overwrite it with stale values.

Frontend: Replace inline SpoolInfoCard/UnknownTagCard with full-screen
TagDetectedModal that auto-opens on NFC tag detection. Known spools show
remaining weight, fill bar, and offer "Assign to AMS" (new sub-modal with
printer selector + AMS slot grid) and "Sync Weight". Unknown tags offer
"Add to Inventory" and "Link to Spool". Modal stays open on tag removal,
won't re-open for dismissed tags, reopens on re-place after removal.
Daemon: Fix PN5180 NFC reader failing to detect tags. Each
activate_type_a() call returning None corrupts the PN5180 transceive
state, silently preventing all subsequent tag detection. Fixed by
performing a full hardware reset (RST pin toggle + RF re-init) before
every idle poll (~240ms, ~1.8 Hz rate). When a tag is present, a light
RF off/on cycle (13ms) resets the card from ACTIVE to IDLE state for
continuous re-selection. Also added error-based recovery, periodic
status logging, and accurate heartbeat NFC/scale health reporting.

Daemon: Fix PN5180 NFC reader failing to maintain tag detection. After a
successful SELECT the card stays in ACTIVE state and ignores subsequent
WUPA/REQA. Added a conditional RF off/on cycle (13ms) before each poll,
but only when a tag is present — resets card from ACTIVE to IDLE for
re-selection. The cycle is skipped when idle to avoid degrading reader
state with continuous RF toggling, which prevented new tags from being
detected after removal. Also added a preventive full hardware reset every
60s when idle to recover from deeper stuck states, error-based recovery
after 10 consecutive exceptions, and accurate heartbeat reporting of
NFC/scale health.

Daemon: Fix PN5180 NFC reader failing to maintain tag detection. After a
successful SELECT the card stays in ACTIVE state and ignores subsequent
WUPA/REQA, causing immediate false "tag removed" events. Added a brief
RF off/on cycle (13ms) before each poll to force cards back to IDLE
state. Also added a preventive full hardware reset every 60s when idle
to recover from deeper stuck states where activate_type_a() silently
returns None without exceptions. Heartbeat now reports actual nfc_ok/
scale_ok instead of hardcoded True.

Daemon: Fix PN5180 NFC reader silently stopping tag detection. The reader
drifts into a stuck state where activate_type_a() returns None without
raising exceptions, making error-based recovery useless. Changed the
preventive idle maintenance from a lightweight RF off/on cycle to a full
hardware reset (RST pin toggle + RF re-init) every 60s — the same reset
that a service restart performs. Also added error-based auto-recovery
after 10 consecutive exceptions, promoted poll errors to WARNING, added
periodic status logging, and fixed heartbeat to report actual nfc_ok/
scale_ok instead of hardcoded True.

Enlarge all interactive elements across 9 SpoolBuddy components to meet
44px minimum tap targets on the RPi touchscreen. Increase nav icons
(20→24px), labels (10→12px), bar heights, section headers, printer
buttons, spool visualizations, fill bars, and status indicators.
Compact the dashboard stats bar and remove the printers card. Add
fullScreen prop to ConfigureAmsSlotModal with two-column layout
(filament list left, K-profile + color right) to eliminate scrolling.
When Bambuddy auth is enabled, the SpoolBuddy kiosk gets redirected to
the login page because ProtectedRoute requires a user from GET /auth/me,
which only handled JWT tokens. The kiosk daemon already has an API key
but couldn't use it to satisfy the frontend auth check.
- Backend: /auth/me now accepts API keys (Bearer bb_xxx or X-API-Key)
and returns a synthetic admin UserResponse with all permissions
- Frontend: AuthContext reads ?token= from URL on first load, stores in
localStorage, and strips from URL (prevents history/referrer leakage)
- Install script: kiosk URL now includes ?token=${API_KEY}
- Tests: 3 new integration tests (Bearer API key, X-API-Key header,
invalid key rejection)
