In-app updater was failing on installs whose local clone had stale
tags (e.g. v0.2.1 re-pointed upstream after a post-release re-tag).
git fetch --prune --tags returns a non-zero exit when even one tag
would be clobbered, even though origin/main and the target release
tag itself fetched cleanly:
! [rejected] v0.2.1 -> v0.2.1 (would clobber existing tag)
...
ERROR Git fetch failed: From https://github.com/maziggy/bambuddy
The updater surfaced this as "Failed to fetch updates" and aborted,
leaving the user stuck on the previous release.
Adding --force lets the moved tag overwrite the local stale copy.
That matches the in-app updater's contract ("sync me to the remote")
and is what the native update.sh sidesteps entirely by not using
--tags at all. The in-app path can't drop --tags because release-tag
refs (v0.2.4b1, v0.2.4.1, etc.) need to be resolvable locally for the
subsequent git reset --hard.
Regression test asserts --force is in the fetch args alongside the
existing --tags assertion.
The CI-only failure on test_layer_timelapse_expected_archive came from
the test driving the entire on_print_start flow through ~12 patches and
a MagicMock printer, which behaved differently between Python 3.11 (CI)
and 3.13 (local) — execution stopped silently somewhere in the
expected-archive path under CI's pytest-xdist parallelism but completed
locally.
Fix root-shape instead of fix the symptom:
1. Extract the three identical start_session call sites in on_print_start
(expected-archive promotion at 2030, fallback archive at 2554, fresh
archive at 2644) into one helper _maybe_start_layer_timelapse() with
the same external_camera_enabled / external_camera_url guard. The
three inline blocks had already started drifting (#1353 originally
only fixed one of them on the first pass) — the helper keeps them
locked together going forward.
2. Rewrite the test to call the helper directly. Uses SimpleNamespace
(strict attribute access) instead of MagicMock (default-truthy), no
DB mocking, no event loop, no parallel-state surface. Four small
cases instead of two integration-style ones: enabled→starts,
disabled→skips, URL-missing→skips, camera_type default 'mjpeg'.
Test was passing locally but failing in CI on the merge of v0.2.4.1.
Root cause: MagicMock returns a truthy default for any unset attribute,
so mock_printer.plate_detection_enabled was truthy and the production
code's plate detection block ran for real. Locally with ffmpeg present
the capture path completed cleanly (try/except swallowed errors) and
flow continued to start_session. In CI without ffmpeg, the failure path
in capture_camera_frame_bytes prevented execution from reaching the
expected-archive branch's start_session call, so the assert_called_once
on the patched start_session tripped.
Plate detection isn't the subject under test (start_session in the
expected-archive branch is). Setting plate_detection_enabled = False
explicitly on the mock skips that block entirely and makes the test
robust to environmental differences. Test also drops from ~9s to ~2s
since real frame-capture attempts no longer run.
Synthetic value on mock_archive.file_path was "/tmp/fake.3mf" - Bandit
flagged it as "Probable insecure usage of temp file/directory" even
though the string is never used as a filesystem path. Swapped to
"/test/archives/fake.3mf", matching the pattern used in commit 9f1188d7
to clear the same finding on test_library_trash_api.py and
test_pending_upload_display_name.py. No suppression comment needed -
the new path no longer matches Bandit's regex.
The two # noqa: S501 comments on the local-sidecar reachability probes
were using ruff/flake8 suppression syntax; bandit only honors # nosec,
so the scan flagged both calls as high-severity. Switched to
# nosec B501 with strengthened reasoning (reachability/health probe
only, no secrets in the request). No behavioural change.
Opening the Print Queue page fired 404s on /archives/{id}/thumbnail,
/archives/{id}/plates, and /archives/{id}/plate-thumbnail/{n} for any
row pointing at a soft-deleted archive. Two underlying problems wearing
one mask:
1. Cosmetic: the queue API was copying item.archive.thumbnail_path into
archive_thumbnail without checking deleted_at. Soft-delete leaves the
row (so the relationship resolves) but removes the file from disk, so
the cached path was always stale.
2. Functional: a queue item whose 3MF was removed can never dispatch.
Without an explicit cancel, the item sits in 'pending' forever with
no indication to the user about why nothing is printing.
Fix in three parts:
- New _cancel_pending_queue_items() helper, called from soft_delete_archive
alongside the existing print-log thumbnail cleanup. Sets status='cancelled'
+ waiting_reason='Source archive deleted' on every pending queue item
linked to the archive. Only 'pending' is touched - completed/failed/
cancelled rows are historical and untouched. Hard-delete is already
covered by ON DELETE CASCADE on print_queue.archive_id.
- Queue API serializer now checks item.archive.deleted_at before
populating any archive-derived field. New archive_deleted: bool field
on PrintQueueItemResponse signals the soft-deleted state.
- Frontend's getArchivePlates query in QueuePage was gated on archive_id
only - archive_id is the real FK and stays exposed for dispatch/audit,
so added an explicit && !item.archive_deleted clause to respect the
new flag. Thumbnail render and CompactHistoryRow/QueueTimelineView
already gate on archive_thumbnail so the backend suppression alone
covers them.
Regression tests pin cancel-only-pending behavior, soft-deleted
suppression + archive_deleted=True flag, and the sanity guard that
live-archive fields keep flowing through unchanged.
Archives → Print Log was 404-storming the thumbnail endpoint on every
render: PrintLogEntry.thumbnail_path is copied by value from the archive
at write-time, but the FK on archive_id is ON DELETE SET NULL (#1378) so
log entries survive archive deletion to preserve stats history - and the
cached path keeps pointing at a file that was removed when the archive's
directory was deleted. Same shape for failed prints whose extractor never
wrote the thumbnail.
Two-part fix:
1. Route self-heals: get_print_log_thumbnail NULLs thumbnail_path on the
entry and commits before returning 404 when the file is missing on
disk. The frontend's <img> tag is gated on entry.thumbnail_path being
truthy, so the next fetch of the log list skips the request entirely.
2. Eager clear on archive delete: new _null_print_log_thumbnail_paths()
helper called from both soft_delete_archive and delete_archive before
the on-disk files are removed. Avoids the one-time storm for future
deletes; covers both the manual delete route and the auto-purge
sweeper at archive_purge.py.
Regression tests cover soft delete, hard delete via ArchiveService, and
the route's lazy-NULL for failed-print orphans where the file was never
written.
Obico polling could freeze the live camera stream within seconds of opening
the viewer. Cause: when the buffer-reuse path in obico_detection._capture_frame
saw an empty _last_frames[printer_id] entry (stream startup before the first
JPEG lands, or upstream mid-reconnect after a 30s read timeout), it fell
through to capture_camera_frame_bytes() and opened a second RTSP socket. On
firmwares that allow only one camera connection, that second socket forced
the printer to drop the live fan-out connection - the viewer's ffmpeg then
hit its own 30s timeout, looped through 30 reconnects at 0.2s, all racing
the next Obico poll, and the broadcaster pump exited.
Widen the gate from "do we have a buffered frame?" to "is any fan-out stream
registered for this printer?". New is_stream_active() helper checks
_active_streams / _active_chamber_streams independently of buffer state.
_capture_frame consults it first: if a viewer is attached, it returns the
buffered frame when available or None (skip this poll cycle) when not. Never
opens a competing socket while a viewer is connected.
Cost: at most one missed Obico detection cycle per viewer-attach (~10s lag).
Benefit: zero competing-socket events while any viewer is connected.
try_get_active_buffered_frame() refactored to delegate to is_stream_active()
so the two helpers stay in lockstep. The /camera/snapshot caller is unchanged
behaviorally (snapshot is a user-initiated single-shot; falling through to
fresh capture on an empty buffer is the desired behavior there).
Statistics now aggregate over PrintLogEntry (one row per print event,
the same table backing the global Print Log) rather than PrintArchive
(one row per file). A reprint creates a new PrintLogEntry instead of
overwriting the source archive's runtime fields, so:
- a 100 g successful print + a 10 g failed reprint correctly sums to
110 g / 2 prints / 1 successful / 1 failed in Quick Stats and the
Prometheus /metrics endpoint (previously the failed reprint silently
replaced the source archive's data; totals dropped from 100 g to 10 g)
- the archive's card cost/energy_kwh are preserved on reprints (only
the first run writes them); per-run actuals live on PrintLogEntry
- failed/cancelled/stopped reprints record partial-aware filament: sum
of tracked spool deltas when inventory is set up, else estimate
scaled to progress%, else None — prevents the full slicer estimate
from inflating totals on a print that stopped at 10 % progress
PrintLogEntry gains six columns: archive_id (nullable FK, ON DELETE
SET NULL so log entries survive archive deletion preserving #1343
soft-delete-vs-stats decoupling), cost, energy_kwh, energy_cost,
failure_reason, created_by_id. Idempotent SQLite + Postgres migrations.
New per-archive surface:
- archive list response carries run_count / last_run_at /
total_filament_actual_grams / successful_run_count / failed_run_count
via a single batch JOIN, no N+1
- new GET /archives/{id}/runs endpoint returns every PrintLogEntry for
the archive (ARCHIVES_READ permission, newest-first ordering)
- archive cards render an orange "N prints" badge for archives with
more than one run; clicking the badge opens a dedicated PrintLogModal
with date/status/duration/filament/cost columns plus failure_reason
under failed runs. Also reachable via the context menu's new "Print
Log" entry (works for single-run archives too), and embedded at the
top of the Edit Archive modal for context.
The purge_stats=true delete path now hard-deletes linked PrintLogEntry
rows up front so the archive's contribution truly leaves the totals;
without it, ON DELETE SET NULL would orphan the runs and leave them
counting toward stats.
The bridge cache replaced _latest_print_state wholesale on every
push_status arrival. Bambu firmware sends full pushall responses
(with AMS/vt_tray/net.info/lights_report) on reconnect / pushall
requests, but ~1 Hz incremental updates with only the fields that
changed. The first incremental push after a pushall therefore wiped
AMS info from the bridge cache, and slicers reading the cache (via
the VP's 1 Hz status push) saw a stripped-down state with no AMS
visible until the next pushall — typically only on a manual printer
power-cycle.
Preserve a small set of slicer-visible sticky keys from the previous
cache when the incoming push doesn't carry them: ams, vt_tray,
ams_extruder_map, mapping, net, ipcam, lights_report. Mirrors the
same pattern Bambuddy uses for its own internal state.raw_data.
Both the queue-side _watchdog_print_start and the direct-dispatch
_verify_print_response used `status.state != pre_state` to decide
whether a project_file command had been accepted. When a printer was
in FINISH at dispatch time (un-dismissed post-print prompt from a
prior job), the firmware silently rejected the new command; if the
user then dismissed the screen prompt, the printer moved FINISH ->
IDLE and the watchdog returned early as "command landed" — leaving
the queue row stuck at status='printing' indefinitely and the
scheduler permanently marking the printer as busy.
Narrow the "command landed" check in both verifiers to an allow-list
of active-print states (PREPARE / SLICING / RUNNING / PAUSE).
Inactive transitions (FINISH -> IDLE, etc.) no longer short-circuit
the revert. The subtask_id-advance signal stays in place for H2D's
slow FINISH -> PREPARE transition (#1078).
Also wrap _watchdog_print_start's revert commit and
printer_manager._persist_awaiting_plate_clear in run_with_retry so
SQLite single-writer contention can't silently drop these writes.
The revert path returns a tristate sentinel so the post-revert MQTT
session-recovery logic only runs when we actually reverted (or the
commit failed) — not when on_print_complete had already cleared the
row, where a forced reconnect could break a healthy concurrent print.
The #765 guard against shutdown-time data wipes skipped any AMS update
with power_on_flag=False, but some X1C firmware emits power_on_flag=False
while idle with tray_exist_bits still reflecting the real slot inventory.
Older firmware (01.08.02.00) doesn't emit per-tray state=9/10 events, so
the bitfield path is the only signal — muting it left spool removals
undetected until a manual reconnect.
Narrow the skip to the exact shutdown pattern: zero bits AND
power_on_flag=False. Non-zero bits with power_on_flag=False are now
applied. The #765 shutdown protection is preserved (its regression test
uses tray_exist_bits='0' and still passes); newer firmwares are
unaffected because their per-tray state path catches the removal first.
Discord's "Copy Webhook URL" button emits discordapp.com URLs; both
hostnames serve the same webhooks. The validation now accepts either
prefix while keeping the check itself in place to catch the
paste-the-wrong-thing error.
archives stop reporting near-zero cost (#1344)
Reporter @nicktags hit $0.01 on a 110.3g multi-color print with the
global default filament cost set to $10/kg. archive.py initial cost
calc was correct (~$1.10), then usage_tracker.on_print_complete
overwrote archive.cost with sum(r.cost for r in results) -- where
results only includes AMS trays mapped to a spool in Bambuddy's
inventory. On a multi-color print where 3 of 4 used trays had no
inventory spool, only the one tracked slot's tiny share (~1g) survived
and the archive recorded $0.01.
The overwrite logic dates to #505 (Feb 2026) and is correct for
fully-tracked single-color prints, but the multi-color slicer feature
in 0.2.4 (988c0055) made the partial-inventory state common -- users
slice + print multi-color from Bambuddy without first setting up an
inventory entry for every tray.
Cover the gap: any filament weight not represented in results gets
charged at the global default rate. For a fully-tracked print,
untracked grams = 0 and the top-up adds nothing, so the single-color
behavior is preserved. For a partial print, the missing slots are
priced at the user's documented default rate so the archive cost
reflects the whole print.
Three call sites updated to share the same logic:
- usage_tracker.py: live cost-update on print complete
- archives.py rescan_archive: per-archive manual recalc
- archives.py recalculate_all_costs: bulk recalc button
Reporter @Andlar94 hit a permanent "Build plate not empty" on every print
start on an A1 with an external RTSP camera. The runtime auto-check at
main.py:1819 called check_plate_empty with use_external=external_camera_enabled,
but the manual UI routes (camera.py) declared use_external: bool = False
and the frontend client always sent use_external=false. So calibration
captured a built-in frame and stamped it as the reference; the runtime
check captured an external frame and diffed it against that reference --
a permanent mismatch.
Centralise the default on the backend: both routes now take bool | None,
deriving the default from the printer's external_camera_enabled +
external_camera_url + external_camera_type. The frontend client stops
sending the flag unless the caller explicitly sets it, so the existing
UI call sites immediately benefit and any future caller gets the right
camera automatically. Explicit overrides still win.
Adds 4 regression tests pinning the new default for both the
external-enabled and external-disabled cases, plus the explicit override
path so a future "always built-in" caller stays supported.
Reporter @maziggy followed the Energy Tracking wiki literally - "create a
key with Write Settings permission, PATCH /api/v1/settings with
{energy_cost_per_kwh: ...}" - and hit:
{"detail":"API keys cannot be used for administrative operations"}.
Triage showed three independent drifts:
1. Wiki listed nine fictional API-key permissions (Read Printers / Write
Settings / Admin / ...) but the UI only ever exposed four toggles
(Read Status, Manage Queue, Control Printer, Allow Cloud Access).
There was no Write Settings toggle to tick.
2. Even if it had existed, the backend hard-denies SETTINGS_UPDATE for
every API key via _APIKEY_DENIED_PERMISSIONS - intentional protection
because PATCH /settings can rewrite SMTP/LDAP/MQTT credentials and the
HA access token. Wider surface than any documented use case needs.
3. So the wiki had been promising a workflow that was never deliverable.
Fix: introduce a narrowly-scoped door rather than relax the deny list.
- New column can_update_energy_cost (default FALSE - existing keys
never silently gain settings-write capability on upgrade).
- New route POST /api/v1/settings/electricity-price accepting
{"energy_cost_per_kwh": <float >= 0>}. Field name matches what the
wiki already documented so the HA rest_command example needs only a
URL+method change, not a payload change.
- Custom dependency require_energy_cost_update() bypasses
_APIKEY_DENIED_PERMISSIONS for this one route for API keys with the
flag set. JWT users still go through standard SETTINGS_UPDATE.
- General PATCH /settings remains denied for API keys - flipping the
narrow flag does NOT widen general settings-write access. Pinned by
test_patch_settings_still_denied_with_energy_flag.
Frontend: fifth "Update electricity price" toggle on the create-API-key
card + amber "Energy" badge on existing keys with the flag set. Three
new i18n keys across all 8 locales (German translated, English fallbacks
elsewhere).
Reporter @Andlar94 ran the external-camera flow on an A1 dispatched via the
print queue and got no MP4 output even though the log said "Stitching layer
timelapse for printer 1" after each print. Support bundle confirmed the
external camera was working (Obico was polling the snapshot URL fine for
plate detection).
Root cause: start_session() only ran in the two new-archive paths in
on_print_start (fallback_archive at main.py:2510 and regular new-archive at
2600). The expected-archive branch at main.py:1981-2052 — where every
reprint and every queue/VP-dispatched print lands — updated the existing
archive row to status=printing but never started a timelapse session.
So _background_layer_timelapse ran at print complete, called tl_complete(),
found nothing in _active_sessions, returned None silently, and the wrapper
at main.py:3917 produced no log message for the no-session case. Every
print through the queue silently lost its timelapse — likely the reason
this hasn't been caught before (direct slice-and-send-to-printer prints
take the new-archive path and work fine).
Fix: mirror the same start_session() call in the expected-archive branch,
guarded by the same external_camera_enabled + external_camera_url check the
other two paths use.
Also reworded the snapshot URL help text across all 8 locales to make clear
that timelapse and plate detection each require their own per-printer
toggle — the URL is just the image source they pull from when active. The
previous wording read as if filling in the URL was sufficient.
Follow-up to the #1322 root fix. Reporter @RosdasHH traced the raw MQTT
payload and found that P1S and A1 Mini send only {"id": N} for a
physically empty slot — no state, no tray_type, no other fields. Without
that signal, the assign-spool path was firing one wasted MQTT publish per
click on a truly-empty slot (firmware dropped it silently, but still).
The AMS parser in printer_manager.py now detects the bare-tray shape and
promotes it to state=9 — the firmware's explicit "no spool" code — which
lets the existing state in {9, 10} short-circuit in the inventory route
apply automatically.
The detection is intentionally narrow:
len(tray) == 1 and "id" in tray and state is None
so the post-Reset-Slot A1 Mini BMCU case (populated payload with state=3
and tray_type="") has more than one key and stays unaffected — the #1322
root fix is preserved.
Add `# pragma: allowlist secret` markers to the three lines GitGuardian
flagged (ldap_server_url, ldap_bind_dn, admin_password) and pull the
duplicated AdminPass1! literal into a single test_password variable so
the marker only needs to live in one place.
All values are test fixtures (test directory + admin password used only
by the LDAP provisioning integration suite), not real credentials.
Reporter @Fuechslein flagged that disabling LDAP auto-provision left admins
with no UI path to onboard new users — the create-user form had zero LDAP
awareness and the only workaround was hand-editing the database.
Add a Local / LDAP tab toggle to the create-user modal (hidden when LDAP is
disabled). The LDAP tab is a debounced directory search (≥2 chars, 300ms)
that returns up to 25 matches via the service-account bind, annotated with
already_provisioned so existing usernames render disabled. Clicking
"Provision user" re-resolves via the service bind and creates the user
through the same _provision_ldap_user helper the auto-provision login path
uses, so group mapping, default-group fallback, and email sync are identical
regardless of which path created the user.
The picker component is shared across all four create-user modal paths
(UsersPage basic + advanced, SettingsPage basic + advanced).
Two ldap3 schema-check workarounds were needed for OpenLDAP installs:
- Open the search connection with check_names=False so ldap3 doesn't reject
the cross-schema OR filter (sAMAccountName/displayName are AD-only)
- Request attributes=["*"] because ldap3's build_attribute_selection
validates each named attribute against the server schema regardless of
check_names, and only the * wildcard is in its hard-coded exclusion list
Login/lookup paths keep check_names=True so typos in user_filter still fail
loudly.
Backend
- New routes: GET /auth/ldap/search, POST /auth/ldap/provision (both gated
by USERS_CREATE; 503 details include ldap3 exception class + message)
- Extract _open_service_connection + _extract_user_info helpers so
authenticate_ldap_user, lookup_ldap_user, and search_ldap_users share the
bind and attribute-extraction logic
Frontend
- New LdapUserPicker component (debounced search, result list, provision
mutation, already-provisioned guard, error surface)
- Tab toggle wired into UsersPage and SettingsPage modals, plus
CreateUserAdvancedAuthModal props
- 14 i18n keys added to en.ts (other locales fall back to English)
The original #1322 fix widened empty-slot detection to (state == 11 OR
tray_type != ""), which closed the configured-slot reconfig case but
didn't help the "Reset Slot on printer screen with spool still inserted"
flow. On these firmwares the AMS reports state=3, tray_type="" after a
Reset Slot regardless of whether a spool is physically present, so the
empty-detection still decided "empty", skipped MQTT, marked pending —
and on_ams_change replay never re-fired because the AMS never reported
any state change either.
RosdasHH traced the path: tray_state=3 falls into the else: branch,
slot_is_empty = not (fingerprint_type and fingerprint_type.strip()),
fingerprint_type is "", so slot_is_empty=True, MQTT is skipped, and the
slot stays unconfigured forever. He verified empirically that removing
the gate makes the firmware accept the push when a spool is physically
present.
Drop the tray_type fallback entirely. Only state in {9, 10} (firmware's
explicit "no spool" / "spool present but no feed") short-circuits the
MQTT publish. Every other state — including 3 (default-idle, ambiguous)
and missing-state (older firmwares) — attempts the publish. Bambu's
"firmware silently drops on empty slots" behavior makes the worst case
a no-op for a truly-empty slot, and on_ams_change replay still serves
as the safety net for state=9/10 slots whose spools get inserted later.
pending_config is now (slot_is_definitely_empty OR not configured) so a
printer-offline / no-client publish failure correctly flags the
assignment for replay instead of falsely showing "configured".
The firmware update dialog showed "01.11.02.00 newer · Unavailable" with the
misleading error "Firmware file is not available from Bambu Lab" while the
logs spammed "Failed to get Bambu Lab page: 403". The wiki scrape was fine —
only the Next.js buildId fetch on bambulab.com was being blocked by Cloudflare
on the reporter's network, and the buildId was cached in memory only, so a
single 403 broke download-URL resolution for the rest of the session.
- Send Accept + Accept-Language headers alongside the honest Bambuddy/1.0 UA
so the request stops tripping Cloudflare's "bare scraper" signal.
- Persist the buildId to <data_dir>/firmware/build_id.json so a transient
403 or a backend restart can't wipe a previously-valid buildId.
- Add a download_page_unreachable flag and use it in the prepare-update flow
to render an honest error ("page unreachable from this network — try later
or download manually from bambulab.com") instead of implying Bambu doesn't
have the file.
- Retry the per-model JSON once when a cached buildId returns 404 (page
rebuild), give up gracefully on 403 without churning.
Reported by @IndividualGhost1905: printing the same model ten times and
then deleting nine archive entries (to keep the file list tidy) silently
rewound the totals on the Statistics page — total prints, filament,
cost, and per-print energy all dropped back to whatever the surviving
row contributed, as if the other nine prints had never happened.
Root cause: every metric in get_archive_stats is recomputed live from
PrintArchive rows via COUNT / SUM, so removing a row removes its
contribution. Energy in the default "Total" mode already survived
deletion because it reads the smart-plug lifetime counters — that's
the architectural shape we now generalise to the rest.
Fix: soft delete with opt-in hard purge.
Backend:
- New nullable, indexed deleted_at column on print_archives, dialect-
conditional migration (DATETIME on SQLite, TIMESTAMP on PostgreSQL).
- ArchiveService.soft_delete_archive flips deleted_at and removes the
files from disk (still reclaims storage); the path-safety checks were
extracted into _resolve_archive_dir_for_delete so soft and hard delete
share the rules.
- DELETE /archives/{id} accepts ?purge_stats=true; default is soft.
- Listings filter deleted_at IS NULL: list_archives, search FTS + LIKE
fallback, GET /{id} (404 on soft-deleted), tag listing, duplicate
detection (so a 1-live + 9-soft-deleted group no longer marks the
survivor as a duplicate), and ArchiveComparisonService's "similar"
suggestions. GET /stats and GET /slim deliberately do NOT filter so
Quick Stats and the dashboard widgets keep counting deleted prints.
Frontend:
- ConfirmModal gained an optional children slot.
- ArchivesPage (both card and detail views) own a per-instance
deletePurgeStats boolean and render an opt-in checkbox in the delete
dialog; resets to off on every close so the destructive option is
never sticky.
- api.deleteArchive(id, purgeStats?) appends ?purge_stats=true only
when the box is ticked.
- One new i18n key archives.modal.deletePurgeStats added across all 8
locales (full German, English fallbacks elsewhere).
* feat(auth): proxy OIDC provider icons server-side (#1333)
Strict img-src CSP blocked external OIDC icon hosts on the login page.
Loosening CSP was rejected via the MakerWorld precedent, so icons are
proxied: admin sets icon_url, backend fetches and caches the bytes in a
deferred BLOB column, the SPA renders from a same-origin
/api/v1/auth/oidc/providers/{id}/icon endpoint.
The assign flow was sending slicer-invalid values for tray_info_idx and an
empty setting_id, which the slicer rejected — slot detail modal showed
empty fields. With a stored k-profile the realignment path masked the
issue; without one, garbage hit MQTT.
Backend (apply_spool_to_slot_via_mqtt):
- Discard tray_info_idx values that aren't real preset IDs: literal
material names ("PLA", "PETG-CF") AND PFUS-prefix cloud setting_ids
(valid as setting_id but rejected as tray_info_idx). Same check applied
to current_tray_info_idx so stale slot values don't get reused as
garbage.
- Local-preset path now reads the printer-recognized filament_id from
the preset's setting JSON (e.g. P4d64437) instead of falling through
to a generic material ID.
- Derive setting_id from filament_id_to_setting_id when empty so
ams_filament_setting always carries a matched pair.
- No stored k-profile: always send cali_idx=-1 (Default K), regardless
of the live cali_idx on the slot. The live value belongs to whatever
filament was there before, so reusing it would apply the wrong K to
the new spool.
Frontend (spool-form/utils.ts):
- Local preset options use String(preset.id) as the unique code instead
of preset.filament_type — every PLA local preset was collapsing onto
the same "PLA" code, so picking any of them saved slicer_filament=
"PLA" and lost the specific preset identity.
Spoolman counterpart in spoolman_inventory.py mirrors the cali_idx=-1
reset.
Slicing an STL via the integrated slicer always defaulted to whatever
curr_bed_type lived in the chosen process preset (typically "Cool
Plate"), which the slicer CLI rejected for high-temp filaments with
"Plate 1: Cool Plate does not support filament 1". The user had no
way to switch plates without cloning the preset in BambuStudio.
The Slice modal now exposes a Build plate dropdown with the six
canonical BambuStudio / OrcaSlicer plates (Cool Plate, Cool Plate
SuperTack, Engineering Plate, High Temp Plate, Textured PEI Plate,
Smooth PEI Plate) plus an "Auto (use process preset)" option that
preserves the previous behavior. Positioned between Process profile
and Filament rows so a long filament list never pushes it off the
modal's scrolled viewport, and always enabled regardless of whether
the user picked a Printer Preset Bundle.
A new bed_type field on SliceRequest flows through both dispatch
paths:
- Resolved-preset path: _patch_process_bed_type overwrites
curr_bed_type on the process JSON before forwarding to the sidecar.
Works end-to-end today, no sidecar change needed.
- Bundle dispatch path: slice_with_bundle adds a bedType form field
to the sidecar multipart. The sidecar (maziggy/orca-slicer-api
fork) needs a matching change to honor it as --curr_bed_type on
the CLI invocation; until then the field is silently ignored and
the slice runs with the bundle's default plate.
A1 Mini BMCU (01.07.02.00) and P1S Standard AMS (00.00.06.75) always
report tray.state=3, even for loaded configured slots. The empty-slot
detection preferred state==11 with tray_type as a fallback only when
state was absent, so every assign was classified as empty and MQTT
was skipped — both for "assign to unconfigured slot" and the secondary
"PETG over a PLA-configured slot won't reconfigure" symptom.
Empty-slot detection in the assign route and the on_ams_change replay
now treats the slot as loaded when EITHER state==11 OR tray_type is
non-empty. Reset-slot case (state=11 + tray_type="") still works
through the first clause; configured slots on these firmwares now
work through the second.
Truly empty unconfigured slots (state!=11 + tray_type="") still hit
the pending-config path, and the deferred publish now fires when the
user later configures the slot in Bambu Studio (tray_type goes
non-empty), since the replay uses the same disjunction.
Bambuddy's external SpoolmanDB lookup in `_find_or_create_filament` matched
on material+color only, with no manufacturer filter. Because SpoolmanDB is a
multi-vendor catalog and entries are roughly ID-sorted, the first hit for
any common combination is almost always a competitor — `bambulab_pla_black_1000_175_n`
is the 15th entry for PLA + `#000000`. Bambu Lab RFID spools were being
labeled with competitor product names (`3DJAKE Black`, `3DXTECH™ Black`, etc).
Restrict the external-library loop to entries whose manufacturer is
`"Bambu Lab"` (with `id.startswith("bambulab_")` as a defensive fallback
for schema drift). When multiple Bambu Lab candidates exist, prefer the
entry whose `name` equals the AMS `tray_sub_brands` so `"PLA Basic"` wins
over generic `"Black"` when both are present. Forward `density` from the
chosen external entry so it is no longer overwritten by the PLA-default
1.24 in `create_filament`.
Six unit tests added: internal short-circuit preserved, non-Bambu external
entries skipped, PLA Basic > generic PLA tiebreaker, no-match fallback,
id-prefix defensive fallback, density propagation.

On A1 / A1 Mini, clicking the "Up" arrow on the printer-card bed-jog
control sent the nozzle straight into the build plate. Reporter
triggered it with the 50 mm step and crashed their nozzle.
Root cause: the bed-jog UI was designed against the X1 / P1 / H2 family
where the bed is the Z-axis and Bambu's firmware homes Z=0 at the top,
so G1 Z- raises the bed toward the toolhead (decreases the nozzle-bed
gap). The frontend maps "Up" to negative distance with that convention
in mind.
A1 / A1 Mini are bed-slingers: bed moves on Y, toolhead moves on X+Z,
firmware uses standard cartesian Z (Z+ = toolhead up). On those models
G1 Z-10 drives the toolhead DOWN 10 mm. There was no model
classification at the bed-jog code path, so every printer got the same
X1-convention G-code.
Fix: new is_bed_slinger(model) helper in printer_manager (sibling to
existing supports_chamber_temp / has_stg_cur_idle_bug, reuses the
already-defined A1_MODELS frozenset which covers display names and
internal codes N1 / N2S). The bed-jog route now inverts the signed
distance before emitting G-code when the printer model is in that set,
so UI "Up" semantics ("decrease nozzle-bed gap") stay consistent
regardless of which physical part moves. Frontend untouched, single
source of truth lives in the backend, keyed off the Printer.model
column. Route Query description and docstring updated to spell out the
new contract: distance is the gap adjustment, not the raw Z value.
Editing a spool's color name on Spoolman-backed inventory appeared to
accept the new value but the inventory list column and the next edit
showed it back to the subtype. Three layers stacked to produce this:
1. find_or_create_filament matches by material/name/color_hex/vendor —
color_name is intentionally not part of the match key, but on a
match it returned the existing filament's id unchanged, silently
dropping the new value.
2. The read helper falls back to subtype when filament.color_name is
empty (kept on purpose: without it Spoolman installs that don't
fill the field render every spool as "Unknown color").
3. The edit form prefilled color_name from spool.color_name — which
on those installs was the synth value. Changing subtype but not
color_name silently round-tripped the OLD subtype back to Spoolman
as if it were a real user-set color_name.
Fixes:
- find_or_create_filament now patches the matched filament's
color_name via the existing patch_filament wrapper when the request
differs. Parameter convention: None = don't touch, "" = explicit
clear, any other string = set/update. A patch failure is logged but
does not block the match.
- The PATCH route uses model_fields_set to distinguish "field omitted"
from "field explicitly set to null" (mirrors the existing
storage_location pattern at the same site).
- The map helper returns color_name_is_synthesized: bool. The edit
form leaves the input blank when true, so the user sees the real
stored state and can't accidentally round-trip the synth value back.
fix(auth): cleanup orphan OIDC/MFA rows on user delete (#1285)
Three User-FK tables (user_oidc_links, user_totp, user_otp_codes)
declare ON DELETE CASCADE in their models, but SQLite ships with
PRAGMA foreign_keys=OFF (the project's existing pattern, mirrored
for APIKey in PR #1182). Without explicit DELETEs, deleting a user
on SQLite leaves orphan rows behind:
Issue #1312 follow-up. Investigation traced the "Name cannot be empty"
report to a sidecar image pre-dating the /profiles/bundle endpoint
addition. Two changes so the next occurrence is self-diagnosable from
the support bundle without a manual curl.
Backend: new _fetch_slicer_health(url) helper does a 2s GET on /health,
walks every non-dataPath key under checks looking for a version field
(the wrapper labels both sidecars as checks.orcaslicer regardless of
which CLI is bundled). _collect_slicer_api_info now exposes
bambu_studio_version and orcaslicer_version. Strips trailing slash
before appending /health to avoid double-slash 404s.
Docs: bambuddy-wiki/docs/features/slicer-api.md gains a Quick Start
callout that branch-built sidecars don't auto-update, a corrected
/health troubleshooting entry (both "unknown" version and "orcaslicer"
field name on bambu-studio-api are cosmetic wrapper bugs, not stale-
image indicators), a new "Name cannot be empty" troubleshooting entry,
and an Updating section that requires --no-cache --pull together
(BuildKit caches the git context separately from layers, so --no-cache
alone silently reuses the old checkout).
The route mapped sidecar 4xx/5xx to HTTPException with detail but never
logged it. Reporters seeing a 400 toast were giving us only the status
code, not the reason, and the access-log line was all that landed in
support bundles.
Add WARNING-level logs on each error branch (400 SlicerInputError,
503 SlicerApiUnavailableError, 502 SlicerApiError) with the sidecar's
own message + the filename / byte count / configured URL. Next reporter
on this code path produces a support bundle that contains the answer.
The settings-table passthrough auto-captured everything in `settings` (with
sensitive-key redaction), but features storing config in dedicated tables
were invisible. Triaging recent OIDC / 2FA / group bugs and the X1C slicer
investigation needed data that wasn't in the bundle.
New blocks in _collect_support_info:
- auth: OIDC providers (cleartext names, no secrets), TOTP / OTP /
API-key / long-lived-token / group counts
- library: file / folder / external / trash / makerworld totals
- inventory: spool + k-profile counts
- queue: pending count, oldest pending age
- maintenance: items total + enabled
- integrations.github_backup: providers used + recent failures
- integrations.slicer_api: enabled, URL source, reachability ping
- per-printer obico_enabled flag
Plus three smaller fixes caught testing against a real bundle:
- mqtt_broker no longer leaks (broker keyword added)
- virtual_printer_tailscale_auth_key no longer leaks (auth_key keyword
+ tskey- value-prefix safety net for future Tailscale settings)
- slicer-API reachability check now mirrors the route's three-level URL
precedence (DB → env var → default), instead of only looking at the
DB setting. Previously returned null for every installation running
the sidecar via env var or default port — i.e. most of them.
Restarting Bambuddy mid-print misfired the plate-check + archive flow.
The is_new_print guard treated _previous_gcode_state=None → RUNNING as
a transition, but None just means we haven't seen any prior state yet —
catch-up from a printer that was already running, not a fresh start.
Add `_previous_gcode_state is not None` to the guard. _was_running still
flips on unconditionally, so completion detection is unchanged. 3 tests
that asserted the buggy behavior now seed an explicit prior state; new
regression test pins the contract for the reporter's exact scenario.
External scan hung on a 1200-subdir NAS because (1) every STL crashed
with TypeError ('str / str') inside generate_stl_thumbnail and (2)
thumbnail generation ran synchronously per file, so the FE timed out
before db.commit() and nothing was persisted.
stl_thumbnail.py now coerces inputs to Path defensively, and
scan_external_folder defers STL thumbnail generation to a background
asyncio task that opens its own session and processes each file
post-commit. Subdirs appear in the sidebar immediately; thumbnails
backfill over the next seconds/minutes.
The Clear Plate button (and 4 other features on the Printers page) read
their state from /settings, which requires SETTINGS_READ. Granting that
permission also adds the Settings nav item and leaks SMTP/LDAP/MQTT
credentials — exactly what users were trying to avoid by giving an
operator only printers:clear_plate.
New /settings/ui-preferences endpoint returns a curated, opt-in subset
of non-sensitive fields. Matches the existing /default-sidebar-order
precedent. PrintersPage switched to the new endpoint; admin pages still
use /settings for full access.
_sync_ldap_user used to replace user.groups entirely on every login,
wiping manual admin assignments to groups outside the LDAP mapping.
Now partitions on LDAP-managed group names (mapping values + default
group) and only rebuilds that slice from LDAP truth. Manual assignments
to non-managed groups are preserved; revocation in LDAP still
propagates for managed groups.
The column existed on the Spool ORM model but was missing from
SpoolBase, SpoolUpdate, and SpoolResponse. Pydantic silently
dropped writes and reads omitted the field, so the inventory
table always showed "—" in the Storage Location column even
after saving. Adding the field to the two schemas is enough —
the update route already uses model_dump + setattr.
Real-printer prints broadcast archive_created from the MQTT print_start
handler, which the Archives page listens for to invalidate its query
cache. The VP file-receive paths created the archive in the DB but
never emitted the event, so the new card only appeared after a tab
switch triggered refetch-on-focus.
Added a small _broadcast_archive_created helper on VirtualPrinterInstance
and called it from _archive_file (immediate mode) and _add_to_print_queue
(queue mode). Review mode is unaffected — it creates a PendingUpload,
not a PrintArchive. Broadcast errors are swallowed at debug level so a
transient WebSocket issue can't break the file-receive flow.
Bambuddy's VP supports two slicer flows: Send (file upload only — what
queue/immediate/review modes are designed for) and Print (file upload
+ start-print, intended for proxy mode). When a user clicks Print
against a non-proxy mode the VP must still respond gracefully — the
file is fine to receive, just the start-print never happens. Instead
the slicer wedged at "Downloading...(0%)" and blocked the next
dispatch with "The printer is busy with another print job".
Cause: on_file_received transitioned gcode_state PREPARE -> IDLE
directly. Print-flow slicers watch the state cycle and only release
their in-flight-job lock on PREPARE -> ... -> FINISH (or FAILED).
PREPARE -> IDLE looks like "printer abandoned my job" and keeps the
prior job pinned in the slicer's memory.
Fix: transition PREPARE -> FINISH with prepare_percent=100. The 1-Hz
periodic status push broadcasts the new state to every connected
slicer within a second. Send-flow slicers don't watch this state so
the change is a no-op for them; Print-flow slicers see the FINISH
they were waiting for and unwedge.
ams_set_filament_setting and reset_ams_slot encoded the single-external
case as {ams_id: 255, tray_id: 0, slot_id: 0}. The "LOCAL tray_id = 0"
comment was a misread of the printer's response (which echoes the local
slot position), not the request semantics.
Captured BambuStudio -> X1C exchange shows the request encoding is
{ams_id: 255, tray_id: 254, slot_id: 0} (global tray index in tray_id).
The previous code's tray_id: 0 is what the P1S in #1279 rejects with
result: "fail", which silently broke external-spool filament selection
on every Bambu printer with no AMS or external spool in active use.
Dual-external (H2D) branch was not in the captured exchange and is
explicitly pinned at the legacy encoding pending a Studio -> H2D capture.
scan_timelapse's Strategy 2 matched filename timestamps against both
archive.started_at and archive.completed_at across seven hypothesised tz
offsets. The filename is always print-START time, so the end-time branch
was a semantic mistake — and the dense offset set [0, +-1, +-7, +-8]
let an unrelated video coincidentally land within minutes of any later
archive at some offset.
Extract Strategy 2 into _match_timelapse_by_timestamp(): compare only
against start time, and refuse to auto-pick when the next-best different
video is within a 15-minute ambiguity margin. The route then returns
available_files and the frontend's existing manual-selection dialog
takes over — which is the fallback the reporter explicitly asked for.
Surfaces in LAN-Only mode where the printer can't reach NTP and its
clock drifts (e.g. P2S filenames in CST while server is in UTC, the
8h offset that exposed this bug).
BambuStudio encodes virtual tray IDs (254/255) as -1 in the flat
ams_mapping array — a convention already documented in
bambu_mqtt.py:start_print(). The spoolman tracking helper was treating
-1 as "unmapped, use position-based default", which mapped slot_id=1
to AMS tray 0 and credited external-spool prints to whatever Spoolman
spool happened to be linked to AMS slot 0. The reporter's TPU prints
on an H2S were credited to a PLA spool for ~49g over 4 prints before
being noticed (regression of #853).
When slot_to_tray[slot_id-1] == -1 and ams_trays contains 254/255,
return the external tray ID directly. Prefers 254 over 255 (matches
single-nozzle tray_now reporting + the vir_slot id=255->254 remap in
bambu_mqtt.py:864). Legacy fall-through preserved for callers that
don't pass ams_trays.
Root cause investigation and patch by @ojimpo.
Prints sent from a slicer to a VP in print_queue mode arrived in the
queue with bed_levelling / flow_cali / vibration_cali / layer_inspect /
timelapse set to the SQLAlchemy column defaults, ignoring the user's
workflow page settings entirely. The manual POST /print-queue endpoint
reads these from the request body (frontend pulls them from settings
before submitting), but manager._add_to_print_queue constructed the
PrintQueueItem without touching any of those fields.
Read default_bed_levelling and the other four settings via get_setting
and pass them explicitly. _bool_setting helper handles the None ->
AppSettings default fallback.
H2C / H2D AMS-HT units report ams_id 128+ (one ams_id per unit, single
tray), but spoolman_slot_assignments.ck_ams_id_range only admitted 0-7
and 255. Every attempt to link a Spoolman spool to an AMS-HT slot died
with `CHECK constraint failed: ck_ams_id_range`. The internal
spool_assignment table has no such constraint and works fine.
Widen the formula to (0-7) OR (128-191) OR 255 in the model, the
CREATE TABLE DDL, and an idempotent in-place migration for existing
installs (Postgres: DROP/ADD CONSTRAINT; SQLite: detect stale formula
in sqlite_master, rebuild via _v2 rename pattern).
The MJPEG fan-out broadcaster from #1089 only solved viewer-side
concurrency. Obico polling (every 5s) and the manual /camera/snapshot
endpoint kept opening their own fresh RTSP sockets, which X1/H2/P2
firmwares tolerated but X2D firmware 01.01.00.00 enforces strict
single-connection on — every poll kicked the live stream.
Add try_get_active_buffered_frame(printer_id): returns the broadcaster's
last buffered frame when a viewer is connected, None otherwise. Obico
and /camera/snapshot consult it before opening a fresh socket. When no
viewer is active they fall through to the existing fresh-capture path.
plate_detection and layer_timelapse intentionally not converted.
