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.
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.
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.
Docs:
- README feature list, CHANGELOG (0.2.3b4 Unreleased),
printer-control wiki page, website features.html.
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
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.
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.
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.
NozzleRackCard computed its rack base via min(present_ids), which breaks
when the lowest-ID slot is the one currently mounted to a hotend — the
firmware omits that ID from device.nozzle.info entirely, so min() picks
the next slot up and every remaining nozzle renders one position too
far left, with the "empty" placeholder pushed off the right end.
Use the fixed H2C rack base of 16 (matching
test_h2c_nozzle_rack_populated_with_8_entries in the backend) so the
empty slot stays anchored to its physical position regardless of which
nozzle is currently mounted.
Adds a frontend regression test covering ID 16 missing.
The SpoolBuddy kiosk's "screen blank timeout" setting only painted a
black CSS overlay over the browser window — the HDMI panel's backlight
stayed on indefinitely, wasting power and risking burn-in on
OLED/LED panels.
Move blanking down to the OS layer:
- install.sh now installs swayidle + wlopm + jq and rewrites labwc's
autostart to launch a new spoolbuddy-idle.sh watchdog instead of the
old `wlr-randr --on` keep-alive loop.
- The watchdog sources /opt/bambuddy/spoolbuddy/.env, derives device_id
from the first non-loopback MAC (same algorithm as daemon/config.py),
fetches the configured blank_timeout from the backend once on boot,
and execs `swayidle -w timeout $T 'wlopm --off HDMI-A-1' resume
'wlopm --on HDMI-A-1'`. Touch/keypress wakes via labwc's input event
path. timeout=0 skips swayidle entirely so existing installs that
never picked a timeout keep their current always-on behavior.
- New GET /api/v1/spoolbuddy/devices/{id}/display endpoint returns the
current brightness + blank_timeout. Gated on INVENTORY_UPDATE (same
level the daemon heartbeat key already uses) so existing SpoolBuddy
API keys work without extra permissions.
- SpoolBuddyLayout drops blanked state, the blank timer, activity
listeners, resetActivity, and the CSS overlay. Runtime updates to
the timeout take effect on next kiosk/browser restart; default for
newly-enabled blanking is 300 seconds.
The Printer tab AMS popup and spool auto-provisioner resolved color
names from hardcoded tray_id_name tables with a suffix-code fallback —
and suffix codes like "R1" are not globally unique across material
families. A17-R1 (PLA Translucent Cherry Pink) fell through the
fallback and resolved to "Scarlet Red" (A01-R1, PLA Matte), baking
the wrong name into auto-created inventory spools.
The fix removes the hardcoded tables entirely. Backend resolves color
names via the existing color_catalog table by hex; frontend fetches a
compact {hex: name} map once per session via a new
GET /inventory/colors/map endpoint (auth-gated but not on
inventory:read — read-only views need it too) and stores it in a
ColorCatalogProvider context. A useSyncExternalStore hook cascades a
re-render into pages mounted before the fetch completes so they
refresh from HSL-fallback names once the catalog loads.
Existing auto-provisioned spools keep their stored names; only new
provisioning and live display benefit. Co-Authored-By is intentionally
omitted here per project convention — set it via git config if needed.
The Statistics page reported "Gesamt" (All Time) kWh correctly but showed
zero for Today/Week/Month in total-consumption mode. Two bugs drove it:
1. The starting plug counter was kept in an in-memory dict
`_print_energy_start` that was lost on any backend restart mid-print, so
the per-print `energy_kwh` delta silently never got computed. The stats
endpoint's fallback path `SUM(PrintArchive.energy_kwh)` therefore summed
to zero for users running in total mode.
2. Total-consumption mode has no per-print delta by design — it includes
idle/preheat/standby — so the fallback to archive rows was the wrong
strategy even when the data existed.
Fix, in two parts:
- Persist `energy_start_kwh` on the archive row and read it back from a
fresh session at print end. Deletes `_print_energy_start` and its 5
call sites, replacing them with a single `_record_energy_start()` helper.
Per-print tracking is now restart-resilient regardless of tracking mode.
- Add hourly `smart_plug_energy_snapshots` table + `_snapshot_loop()` in
SmartPlugManager. Rewrote the `/archives/stats` energy branch as
`_sum_snapshot_deltas()` which computes per-plug
`max(0, last-in-range - baseline)` where baseline is the latest snapshot
at or before the range start, falling back to the earliest-ever snapshot
and signalling `energy_data_warming_up` when no pre-range baseline
exists (fresh upgrade). MQTT plugs are skipped from snapshots since they
only report "today" and have no lifetime counter.
Frontend: QuickStatsWidget renders an AlertTriangle next to Energy Used /
Energy Cost with a tooltip when `energy_data_warming_up` is true, so the
"low values right after upgrading" situation is explained in-product.
Fully localised across 7 UI languages.
Tests: new backend unit tests cover the snapshot delta arithmetic
(baseline/endpoint, counter reset clamp, multi-plug, warming-up fallback,
endpoint windowing), per-print restart resilience via expunge_all, and the
snapshot task lifecycle (start idempotent, stop cancels). Frontend tests
assert the warning icon appears only when the flag is set and only on the
energy tiles.
Docs: updated `CHANGELOG.md`, `README.md`, wiki `features/energy.md`,
wiki `features/statistics.md`, and website `features.html` with the new
behaviour and warming-up explanation.
Previously, if a SpoolBuddy daemon crashed during registration it could
end up registered twice. The kiosk UI silently used only the first
device and there was no UI path to remove the orphan — administrators
had to delete the row directly in the database.
Adds a new Settings → SpoolBuddy tab that lists every registered device
with live connection status, system details (firmware, IP, CPU temp,
memory, disk, OS, daemon + system uptime), hardware health flags, and
an Unregister action gated by a confirm modal. A yellow banner appears
whenever more than one device is registered to flag likely crash-
duplicates. Backend adds DELETE /spoolbuddy/devices/{device_id} gated
by inventory:delete and broadcasts spoolbuddy_unregistered over WS so
other tabs refresh immediately.
The tab header shows a device-count pill and a green/gray status bullet
reflecting whether at least one registered device is online. An online
device that is accidentally unregistered re-registers itself on its
next heartbeat. Localized in English, German, and Japanese. The kiosk
layout still uses devices[0] — once the orphan is unregistered, the
remaining device naturally becomes [0].
Audit PRs #920 (printers search/filter) and #932 (print from project
view) for regressions, i18n coverage, test gaps, and docs.
No regressions found: existing callers of the changed signatures
(archive_print, getLibraryFiles, filteredPrinters chain) are unaffected;
i18n is complete in all 7 locales for both features.
Backend tests (4 new, all passing):
- test_list_files_by_project_id — bulk JOIN returns files across all
linked folders, excludes unlinked ones
- test_list_files_folder_id_takes_precedence_over_project_id — guards
the documented precedence folder_id > project_id > include_root
- test_add_to_queue_with_project_id — project_id is persisted on the
queue row for later archive linkage
- test_add_to_queue_invalid_project_id_returns_404 — regression guard
for the validation pre-check on the queue path (mirrors the one on
the direct-print path in library.py)
PR #920 was merged without a CHANGELOG entry and without test coverage
for the location filter dropdown (every other new control — name
search, model search, serial search, whitespace trim, clear button,
status filter, empty states, combined filters — already had tests).
Adds:
- `filters by location via dropdown` — overrides the printers mock so
printer 1 has location 'Workshop' and printer 2 has location
'Office', then verifies that selecting each location shows only the
matching printer and that switching between the two works.
- `hides location filter when no printers have a location` — both
printers get a null location, and the test asserts the status filter
dropdown is still rendered but the location filter dropdown is not.
- CHANGELOG entry under [0.2.3b3] > New Features crediting the
contributor and documenting the search/filter feature, including the
WebSocket-reactive status filter behavior.
The sidebar <img> tag in Layout.tsx fetched custom external-link icons
via a raw /api/v1/external-links/{id}/icon URL. That endpoint is
protected by the shared camera-stream token (passed as ?token=xxx
because <img> tags cannot send Authorization headers), so the request
came back 401 with the "Valid camera stream token required" message.
The edit dialog already routed through api.getExternalLinkIconUrl(),
which wraps the URL via withStreamToken(); the sidebar now does the
same in both the open-in-new-tab and NavLink branches.
The Shortest Job First toggle badge was rendered inside the Pending
Queue section header, which only mounts when pendingItems.length > 0
and the list view is selected. Clicking the toggle often lined up
with the scheduler picking up the last pending item, which unmounted
the whole section and took the toggle with it.
Moved the toggle into the queue page header next to the list/timeline
view switcher so it stays visible regardless of pending-item count,
filters, or view mode. On mobile the view-mode switcher remains
hidden (as before) but the SJF button is visible icon-only.
Two bugs surfaced while investigating camera reconnect behaviour in #925.
The camera page briefly displayed "Reconnecting attempt 6 of 5" before
giving up, because the attempt counter could be incremented to the
maximum while the reconnect banner was still rendering. The displayed
value is now clamped to the configured maximum.
Every failed ffmpeg spawn logged the full ~20-line ffmpeg version,
configuration, and lib* banner, producing hundreds of lines of noise
per failed camera click (one reported click produced 555 log lines
across 30 retries). A new _summarize_ffmpeg_stderr helper strips the
banner and caps output at the last 10 meaningful lines, applied at
all three stderr log sites (immediate-failure, stream-ended,
read-timeout). Covered by unit tests for empty input, banner
stripping, line cap, blank-line filtering, and banner-only input.
The underlying "camera service stops accepting connections after
prolonged uptime" behaviour in the X1C firmware is still under
investigation — these two fixes are independent of that root cause.
Two related LDAP authentication changes.
Fix: POSIX primary group membership was ignored. authenticate_ldap_user
only searched for posixGroup entries via memberUid (supplementary
groups). A user's primary group — referenced by the gidNumber attribute
on the user object matching gidNumber on a posixGroup — was never
resolved, so users whose role came from their primary group landed
without the expected permissions. The authenticator now runs a second
search for posixGroup entries whose gidNumber matches the user's
primary gidNumber, then dedupes DNs case-insensitively before passing
the list to resolve_group_mapping (LDAP DNs are case-insensitive by
spec).
New feature: ldap_default_group setting. Settings → Authentication →
LDAP → Advanced has a new "Default group" selector. When an LDAP user
authenticates but is not listed in any mapped LDAP group, they are
assigned to this fallback group instead of being left with no groups
(and therefore no permissions). A warning is logged each time the
fallback is applied so admins can spot missing group assignments.
Empty setting preserves the old behavior.
Tests: added 4 mocked authenticate_ldap_user tests covering primary
gidNumber lookup, dedupe of overlapping memberUid+primary gid matches,
case-insensitive DN dedupe, and the guard when a user entry has no
gidNumber attribute. Also extended the existing parse_ldap_config tests
to cover the new default_group field.
Backend: ldap_service.py (primary group + dedupe + default_group
field), schemas/settings.py (schema field), api/routes/auth.py
(fallback wiring in _provision_ldap_user / _sync_ldap_user).
Frontend: LDAPSettings.tsx default-group dropdown in the Advanced
collapsible, api/client.ts type field, new i18n keys in all 7 locales
(defaultGroup, defaultGroupNone, defaultGroupHint).
The on_ams_change auto-sync callback set locations for new spools but
never called clear_location_for_removed_spools(), leaving stale locations
that caused double-booked slots. Also pass synced_spool_ids in the
single-printer sync route to match the sync-all endpoint behavior.
The clearPlateMutation.isSuccess state from React Query persisted after
the first successful plate clear. When the next print finished, the
stale isSuccess rendered the static confirmation instead of the clickable
button. Reset mutation state when printer leaves FINISH/FAILED.
Swipe down from the top of the SpoolBuddy display to open a quick-access
menu for toggling printer smart plugs and managing the device (restart
daemon, restart browser, reboot, shutdown). All destructive actions
require confirmation.
Backend: new POST /spoolbuddy/devices/{id}/system/command endpoint
queuing reboot/shutdown/restart_daemon/restart_browser commands.
Daemon: handles commands via subprocess (sudo reboot, systemctl restart).
Frontend: SpoolBuddyQuickMenu component, swipe-down gesture detection,
i18n keys for all 7 locales.

Users can authenticate against an LDAP/AD server with configurable
server URL, bind DN, search base, and user filter. Supports StartTLS
and LDAPS — plaintext is not allowed. Both Active Directory (memberOf)
and POSIX groups (memberUid) are mapped to BamBuddy groups on each
login. Auto-provisioning creates local accounts on first LDAP login.
Local admin accounts remain as fallback when LDAP is unreachable.
Password management is disabled for LDAP users.
Spool CRUD endpoints (create, bulk create, update, delete, archive,
restore) did not emit websocket events, so SpoolBuddy Dashboard and
other tabs relying on event-driven cache invalidation never refreshed.
All inventory mutation endpoints now broadcast an `inventory_changed`
websocket event. Frontend handles it by invalidating `inventory-spools`.
Per-model start/end G-code snippets configurable in Settings (Workflow
tab). Queue items get "Inject G-code" toggle — scheduler injects
snippets into a temp 3MF copy before FTP upload. Supports Farmloop,
SwapMod, AutoClear, Printflow 3D and similar bed-clearing systems.
Original files are never modified.
Stream tokens are stored in-memory and lost on restart. The frontend
cached the old token for up to 50 minutes (staleTime) and never
refetched, so all thumbnail/stream requests failed with 401 until
a manual page reload.
Added a global error listener in useStreamTokenSync that detects
when img/video elements fail to load with the current stream token
and automatically invalidates the camera-stream-token query to
fetch a fresh one. Debounced with a 5s cooldown to avoid spamming
when many images fail at once.
New SJF toggle badge on the queue page. When enabled, the scheduler
picks shorter print jobs before longer ones instead of FIFO. A
starvation guard flags jobs that get skipped once, moving them to
the front on the next cycle so long jobs can't be postponed indefinitely.
- Add print_time_seconds and been_jumped columns to PrintQueueItem
- Cache print duration from 3MF metadata at queue item creation
- SJF query: printer_id, target_model, been_jumped DESC, print_time_seconds ASC, position
- Mark jumped items in-memory after each print start
- Toggle badge on queue page header with live state indicator
- Frontend auto-sorts to match scheduler order when SJF enabled
- Settings schema, boolean parsing, and migration (SQLite + PostgreSQL)
- i18n badge keys for all 7 locales
- 10 integration tests for SJF ordering and starvation logic
- Wiki, website, README, and changelog updated
Printer cards and stream overlay now display the plate number when
printing plate 2+ of a multi-plate 3MF (e.g. "MyModel — Plate 3").
Queue items using model-based assignment ("Any P1S") now show the
actual assigned printer name once the scheduler picks a printer,
instead of continuing to show the generic target.
Display the active database backend (SQLite or PostgreSQL) and its
version in the Database section of the System Info page. SQLite queries
sqlite_version(), PostgreSQL queries SELECT version() and
pg_database_size(). Helps users verify which database is in use.
The "Clear Plate & Start Next" button on printer cards appeared
even when "Require plate-clear confirmation" was disabled in
Settings. The backend correctly auto-dispatched without waiting,
but the frontend widget always showed the prompt. Thread the
require_plate_clear setting through PrinterCard → PrinterQueueWidget
so the widget shows a passive queue link when the setting is off.
REST/Webhook smart plugs can now fetch power and energy data from
individual URLs instead of requiring all values in a single status
response. Each value falls back to the shared Status URL when no
separate URL is set, preserving backward compatibility. Added power
and energy multipliers for unit conversion (e.g. 0.001 for Wh→kWh).
The bottom message bar showed stale warnings from the previous printer
after switching via dropdown or swipe. Cached AMS data was shared across
all printers in a single ref, so switching to a printer whose status
hadn't loaded fell back to the wrong printer's data. The Layout also
unconditionally cleared alerts set by child pages. Fixed by keying the
AMS cache per printer ID and only clearing Layout-owned alerts.
