Two root causes in the "Camera View Mode = Window" path when auth is on (#979):
1. PrintersPage opened the popup with `noopener`, which severed the opener
link and prevented the browser from copying sessionStorage (auth token)
into the new window. The popup booted unauthenticated, POST
/printers/camera/stream-token returned 401, and the <img> src went out
with no ?token=. The backend's RequireCameraStreamTokenIfAuthEnabled
then rejected every frame with "Valid camera stream token required".
2. CameraPage computed its stream URL from the module-level stream-token
cache in withStreamToken(). That cache is populated by a useEffect in
useStreamTokenSync that runs after render, so even after the token
resolved the first post-arrival render still produced a tokenless URL
and nothing triggered another render.
Fix:
- Drop `noopener` from the camera popup features (same-origin, trusted).
- Subscribe CameraPage to the `camera-stream-token` React Query so the
page re-renders the moment the token arrives.
- Gate currentUrl on `waitingForStreamToken` and append the token directly
from the reactive query value instead of the effect-synced module cache.
Embedded overlay mode was unaffected. Added CameraPage tests covering both
the auth-enabled (token required, src empty until it arrives, then includes
?token=) and auth-disabled (src rendered immediately without token) paths.
Two-part root cause for missing photos/filament/cost on large prints
(#972). The configured ftp_timeout was only plumbed through as the FTP
socket timeout; the asyncio.wait_for wrapping run_in_executor stayed on
its 60s hardcoded default, so the user's 300s setting never applied.
Worse, asyncio.wait_for cannot cancel run_in_executor threads — after
the 60s outer timeout fired, the executor thread kept running
ftplib.retrbinary and frequently completed the download ~30–60s later,
but by then the async wrapper had returned False. with_ftp_retry kept
re-attempting the same path, each retry truncating the file the zombie
thread had just written, and the archive was ultimately persisted as a
fallback with no 3MF.
download_file_async now accepts timeout at each call site (plumbed from
ftp_timeout) and salvages post-timeout success via an explicit
completion flag the executor thread sets only after download_to_file
returns True. Per-attempt completion dict so a prot_p zombie can't
flip the flag for a later prot_c attempt. A cosmetic // prefix in the
directory-search download path is also fixed by replacing string
concatenation with posixpath.join.
Four attempts at making the printer-card SD badge stable on H2D all failed:
the final straw was powering on an A1 causing every connected H2D to flip to
red simultaneously. Bambu firmware SD signaling is not reliably derivable
from MQTT — the legacy `sdcard` field is sporadic and inconsistently typed,
and home_flag bits 8-9 are cleared on heartbeat pushes regardless of card
state with no clean way to distinguish heartbeats from full status reports.
Remove the badge from the Printers page card and the Printer Info modal,
drop `sdcard` from the frontend PrinterStatus type, and strip all home_flag
derivation and heartbeat-handling code from the MQTT parser.
`state.sdcard` is retained on the backend and populated only from a plain
truthy read of the `sdcard` field, because firmware_update.py uses it as a
precondition before starting firmware installs.
Third follow-up on the H2D SD card badge. The prior 3-strike downgrade still
lost the race: on idle printers, a nearby printer coming online (e.g. an A1
reconnecting) triggered an MQTT activity burst that let idle H2Ds accumulate
≥3 heartbeat home_flag pushes before the next full push_status, flipping every
H2D badge to red at once.
Reworked the derivation:
- the top-level `sdcard` field is authoritative when present (truthy check
handles bool / int / "HAS_SDCARD_NORMAL" string variants)
- home_flag bits 8-9 are only consulted on full push_status payloads
(detected via ≥2 of gcode_state, mc_percent, nozzle_temper, print_type,
stg_cur, ams)
- bare heartbeat pushes carrying home_flag alone no longer affect SD state
Removed the now-dead `_home_flag_seen` latch and 3-strike counter. Tests in
TestSdCardParsing rewritten to cover the new semantics.
H2D sends heartbeat-style home_flag pushes where bits 8-9 are clear
even when a card is inserted, so a single heartbeat flipped the badge
to red until the next full push. Downgrades true->false now require
three consecutive clear reads; upgrades apply immediately.
Settings dump now retains every key from the Settings table and replaces
sensitive values with [REDACTED] instead of dropping the row. New config
flags automatically surface in future bundles without a code change.
Adds integrations.spoolbuddy with per-device firmware, NFC/scale hardware,
calibration, online state and uptime — anonymized (no hostnames, IPs or
device IDs). Both /support/bundle and the bug-report bubble benefit, since
they share _collect_support_info().
Adds a compact "Bed" badge in the printer-card controls row
between print speed and Stop/Pause. Opens a popover with up/down
arrows and a 1 / 10 / 50 mm step selector.
When the Z axis has not been homed since the last print, the
first jog per session opens a Bambu Studio-style modal with
Home Z / Move anyway / Cancel. "Move anyway" bypasses soft
endstops (M211 S0 ... M211 S1) for a single move and is
remembered for the browser session.
Backend:
- POST /printers/{id}/bed-jog?distance=N[&force=bool]
Emits G91 / G1 ZN F600 / G90 (with optional M211 wrap).
Distance validated server-side (non-zero, |N| <= 200 mm).
- POST /printers/{id}/home-axes?axes=z|xy|all
Emits G28 variants.
Both gated behind Permission.PRINTERS_CONTROL.
Frontend:
- New indigo-themed badge + popover in PrintersPage.
- Not-homed confirmation modal with sessionStorage "warned" flag.
- i18n keys under printers.bedJog.* in all 7 locales.
Tests:
- backend/tests/unit/test_bed_jog.py — 13 tests covering
404 / 400 / 500 / success paths for both endpoints, plus
gcode-payload assertions for force on/off.

surfaced it as "Failed to get image", which Bambuddy reported back as a 400.
Fix: the snapshot endpoint already accepts a reusable camera-stream token (the same mechanism used by <img>-based camera consumers, since browsers can't send auth headers
on image loads). The detection service now appends that token to the URL it gives the ML API. The token is cached on the service, refreshed 5 min before its 60-min expiry,
and is simply ignored when Bambuddy auth is disabled — so no behavior change for users without auth.
Refs #172
The library POST /files/{file_id}/print endpoint discarded the
authenticated user and passed requested_by_user_id=None to the
dispatcher, so archives created from direct prints had no
created_by_id and didn't show up in per-user statistics. Queue
and reprint paths already forwarded the user correctly.
Bind the auth dependency to current_user and pass its id/username
through to dispatch_print_library_file, matching the reprint
endpoint. The dispatcher already propagates this to
printer_manager.set_current_print_user, which the archive
creation reads.
Firmware update modal now shows every version from Bambu's wiki release
history, each badged Usable/Unavailable/Installed. Selecting a usable row
— newer or older than current — swaps the release notes and enables
install for that version, so rollback no longer requires hand-flashing.
Wiki scraper tightened to only read heading-anchor ids (h-XXXXXXXX-YYYYMMDD)
instead of any XX.XX.XX.XX substring, eliminating false positives like an
AMS firmware version mentioned in an H2D changelog being listed as H2D
firmware.
Refs #568
Exposes the backend auto_link_existing_accounts field in the OIDC provider
form, edit view, and info display. Adds translations for all 7 supported
locales (en, de, fr, it, pt-BR, zh-CN, ja).
On short viewports the modal exceeded the screen height with no scroll,
hiding fields like Access Code and Save. Overlay now scrolls and the
card caps at calc(100vh-2rem) with internal overflow.
Start Drying was publishing a valid MQTT command that the firmware
silently refused. The per-AMS dry_sf_reason array was parsed but never
consulted before publish, so users with the AMS 2 Pro external PSU
unplugged (code 8) saw nothing happen. The empty filament field in our
payload was also a refusal trigger on some firmwares.
The /drying/start route now inspects dry_sf_reason and returns a 409
with a specific message, and backfills filament from the first loaded
tray (default PLA) so the printer can't reject the command for a
missing field.
Settings → Support → Debug Logging elevated httpx/httpcore to DEBUG,
which makes httpx log every outbound request URL. For Discord and
generic webhook notifications the bearer token is embedded in the URL
path, so users who turned on debug logging to capture a support bundle
were writing their webhook tokens straight into bambuddy.log.
Pin httpx/httpcore to WARNING regardless of the debug toggle. paho.mqtt
still honours debug. Users who enabled debug logging while notifications
were sending must rotate any exposed Discord/webhook URLs — the token
is the path, so the whole URL has to be regenerated in the provider UI.
If the printer drops or ignores the MQTT project_file command (same
half-broken-session shape as #887/#936), the queue item was permanently
stuck in "printing" at 100% because the scheduler optimistically flipped
the DB row right after the publish succeeded locally. A new watchdog
polls the printer state for up to 45s after dispatch; if there's no
transition, it reverts the item to "pending" and force-reconnects the
MQTT session so the scheduler can retry.
Follow-up to the earlier H2D SD card badge fix. The badge was still
flapping because Bambu firmwares send partial MQTT pushes carrying only
the legacy `sdcard` field (without home_flag), and the fallback path
re-engaged on every such push. Latch home_flag as the canonical source
once seen; reset the latch on reconnect so a firmware change still
re-learns.
When a project_file command was unacknowledged for 15s, Bambuddy
previously logged "printer may need restart" and left the broken MQTT
session in place — requiring the user to power-cycle the printer. The
existing half-broken-session recovery only ran via the developer-mode
probe path, which skips printers with a known developer_mode value.
Extract the existing force-reconnect logic into a reusable helper and
call it from _verify_print_response on dispatch timeout. The next
dispatch attempt then lands on a fresh MQTT session without a reboot.
New users repeatedly reported queued prints "not starting" because the
confirmation prompt was waiting on an ack they didn't know existed.
Flip the default in the settings schema and in the frontend fallbacks
so a missing/unset value reads as disabled. Existing installs keep
their saved preference.
Parse `sdcard` from `home_flag` bits 8-9 (HAS_SDCARD_NORMAL /
HAS_SDCARD_ABNORMAL) when available and fall back to a type-tolerant
truthy check on the top-level `sdcard` field. Firmware ships that
field inconsistently (bool, int `1`, or string `"HAS_SDCARD_NORMAL"`),
so the previous `is True` identity check flipped the badge to red on
every report that carried a non-bool value.
The strict CSP added in 0.2.3b4 blocked three things at once:
external sidebar-link iframes (no frame-src declared, so they fell
back to default-src 'self'), the inline service-worker registration
script in index.html, and the Google Fonts @import used for Inter.
- Add `frame-src 'self' https:` so user-configured HTTPS iframe
targets load; frame-ancestors 'none' still prevents Bambuddy
itself from being framed cross-origin.
- Move the inline SW-registration script into public/sw-register.js
so `script-src 'self'` covers it without 'unsafe-inline' or
per-build hashes.
- Allow fonts.googleapis.com in style-src and fonts.gstatic.com in
font-src so the Inter webfont loads.
Search field at the top of Settings now finds Sidebar Links,
Spoolman, Spool/Color Catalog, all four Failure Detection
sections, Email auth (Advanced + SMTP test), 2FA (TOTP, Email
OTP, Linked Accounts), SSO/OIDC, LDAP Server Config, and the
four Backup sub-cards (GitHub, History, Local, Scheduled).
Replaces the hardcoded searchIndex array in SettingsPage.tsx
with a module-level registry (frontend/src/lib/settingsSearch.ts).
Each settings card calls registerSettingsSearch(...) at module
scope, so adding a new card means adding one colocated line
instead of editing a distant central array. Anchor ids were
added to the corresponding Card elements in the affected
components so scrollIntoView lands on the right section.
Surface four Home Assistant-style controls on the Printers page card:
- SD Card badge in the top status row (green / red, icon-only).
- Enclosure Door badge in the top status row (green / yellow, icon-only).
Detection per printer family — X1/X1C/X1E read home_flag bit 23, all
others read top-level `stat` (hex string) bit 23 — so X1 firmware that
does not flip stat bit 23 stops false-triggering "open". WebSocket
status-change dedup key now includes door_open so toggling the door
alone publishes a push, no 30s REST-poll wait.
- Airduct Mode badge beside the speed control (cooling / heating)
for P2S/H2D/H2C/H2S; one-click dropdown calls the existing
set_airduct MQTT command via a new POST /printers/{id}/airduct-mode
route.
- Force Refresh entry in the kebab menu — calls the existing
/printers/{id}/refresh-status endpoint to request a pushall snapshot
without forcing a reconnect.
Tests: door-open parsing (X1 home_flag, non-X1 stat, ignore mismatched
source, invalid hex) and airduct route (validation, not-connected,
success, failure).
Adds a Failure Detection tab under Settings that wires Bambuddy to a
self-hosted Obico ml_api container — no cloud, no account, no WebSocket.
While a print is running, the detection service periodically hands the
printer's camera snapshot URL to the ML API and smooths scores over
time (30-frame warmup + EWM, alpha=2/13, short/long rolling means) so
one noisy frame can't trigger an action. When the smoothed score
crosses HIGH, the configured action fires exactly once per print:
notify, pause, or pause-and-cut-power (via linked smart plugs).
- Backend: new obico_detection + obico_smoothing + obico_actions
services, /obico/status and /obico/test-connection routes
(SETTINGS_READ / SETTINGS_UPDATE), six obico_* AppSettings fields
with validators for sensitivity/action/enabled_printers.
- Frontend: FailureDetectionSettings component (enable, ML URL + test,
sensitivity, action, poll interval, per-printer monitor list, live
status + detection history), new sidebar tab with service-active
bullet, toast on save.
- Tests: 17 detection unit tests + 15 smoothing unit tests + 4
frontend component tests.
- Docs: README bullet, CHANGELOG entry, wiki page under Analytics,
website features.html entry.
The security-headers middleware added in 0.2.3b4 set X-Frame-Options: DENY
on every response, which blocked the Spoolman page iframe when Spoolman
was served from the same host as Bambuddy via a reverse proxy. Relaxed
to SAMEORIGIN — same-origin embedding works again, cross-origin
clickjacking protection is preserved.
With Auto Off enabled and another job queued, the smart plug cut power when a
print finished and immediately re-powered the printer because the scheduler
saw pending items. The printer booted fresh into IDLE and the next job
auto-dispatched, bypassing the "Clear Plate & Start Next" confirmation.
Root cause: the plate-clear gate lived only in PrinterManager._plate_cleared
(in-memory set) and _is_printer_idle treated IDLE as unconditionally idle. On
power cycle the in-memory flag was lost and the IDLE-on-boot state skipped
the gate entirely.
Fix:
- Replace the in-memory flag with an awaiting_plate_clear column on the
printers table, rehydrated into the PrinterManager at startup.
- Set the flag in on_print_complete for completed/failed prints (not user
cancellations); clear it on ack and on scheduler dispatch.
- _is_printer_idle now short-circuits to not-idle whenever require_plate_clear
is on and the flag is set, regardless of the currently reported state —
so the gate holds through power cycles, Bambuddy restarts, and the printer
booting back into IDLE.
- /printers/{id}/clear-plate no longer requires the printer to report
FINISH/FAILED; it accepts the ack whenever the flag is raised.
- Frontend widgets (PrinterQueueWidget, Layout, BulkPrinterToolbar) gate on
the flag rather than reported state.
Tests: added regression tests for IDLE+awaiting=True (the #961 case) and
full DB round-trip tests for the persistence layer.
