GET /spoolman/spools/unlinked hid any spool with a non-empty
extra.tag from the AMS-slot assignment picker. extra.tag is only an
RFID/NFC matching key -- OpenSpoolman writes its own NFC tag value
into that same Spoolman field -- so every OpenSpoolman-tagged spool
became un-assignable in Bambuddy even when it occupied no slot.
get_unlinked_spools now determines assignability from the
spoolman_slot_assignments table (the documented source of truth for
slot assignments) and ignores extra.tag entirely. Both link_spool and
the AMS auto-sync upsert a row there for every occupied slot, so the
ledger is complete. get_linked_spools and find_spool_by_tag still use
extra.tag -- they are genuine tag-match maps and are unaffected.
Internal-inventory mode needs no parallel change: it stores tags in
its own DB with no Spoolman extra collision.
Updates test_get_unlinked_spools_success and adds
test_get_unlinked_spools_excludes_slot_assigned.
notify_missing_spool_assignments_on_print_start queried only the legacy
SpoolAssignment table. In Spoolman mode that table is empty -- bindings
live in spoolman_slot_assignments -- so every used tray was flagged
missing, firing a false-positive notification on every print.
- spool_assignment_notifications.py: the assigned-tray set is now the
union of SpoolAssignment + SpoolmanSlotAssignment rows. Union-only,
so legacy-mode behavior cannot regress.
- settings.py: the Spoolman toggle cleared SpoolAssignment on switch-on
but never cleared SpoolmanSlotAssignment on switch-off. Added the
symmetric clear so stale Spoolman rows can't leak into a later
internal-mode session and mask a real missing-assignment warning.
Adds 3 notification tests + 1 mode-switch integration test. An audit
of the remaining SpoolAssignment consumers confirmed usage_tracker,
spool_tag_matcher and routes/inventory are correctly internal-mode-only.
notify_missing_spool_assignments_on_print_start queried only the legacy
SpoolAssignment table. In Spoolman mode that table is empty -- bindings
live in spoolman_slot_assignments -- so assigned_global_trays came back
empty and every used tray was flagged missing, firing a false-positive
notification on every print.
Union SpoolAssignment + SpoolmanSlotAssignment rows for the printer
before computing the missing set. Both tables expose printer_id /
ams_id / tray_id identically, so _global_tray_from_assignment is
unchanged. Union-only, so legacy-mode behavior cannot regress.
The Status panel's Low / High thresholds readout was stuck at 0.38 /
0.78 regardless of the Sensitivity dropdown, so the setting looked
dead. Detection itself was correct -- classify() always used the real
sensitivity -- but get_status() computed the displayed thresholds with
a hardcoded thresholds("medium").
get_status() now takes an optional sensitivity argument and the
/obico/status route passes settings["sensitivity"] (it already loads
settings fresh). The readout updates as soon as the change is saved.
Reporter's H2C connected over MQTT+TLS but every status field stayed
unknown. Root cause was layer-8: the MQTT broker is the printer, it
authenticates on the access code and SUBACKs any topic string, so a
wrong or mis-cased serial connects fine and silently receives nothing
(the report topic device/<serial>/report is case-sensitive; Bambu
serials are uppercase). Bambuddy stored and used the serial verbatim.
- schemas/printer.py: field_validator strip()+upper()s serial_number on
create, rejects blank-after-strip. The subscribed topic now always
matches the printer's correctly-cased one.
- bambu_mqtt.py: count report-topic messages per connection; when a
stale reconnect fires with zero reports received, log a one-shot
hint pointing at the serial number instead of looping silently.
Reporter on X2D set a 1h AMS dry; the printer powered off seconds in.
Support log: every "Sent drying command duration=1" was followed 3-9s
later by "AMS 0 drying complete (dry_time 60 -> 0)" -- the completion
callback fired right after drying started, arming smart-plug auto-off.
Root cause: the tray-bearing branch of the AMS partial-update merge
rebuilt the unit as {**ams_unit, "tray": merged_trays}, never spreading
existing_unit. Tray-bearing partials carry no drying fields, so dry_time
(and info) was dropped; the falling-edge detector read the absent field
as 0 and saw a false 60->0 edge.
- Merge: tray branch now spreads existing_unit first, preserving
dry_time / info / humidity / temp across tray-only partials. Matches
the no-tray branch. Also fixes dry_status/dry_sub_status UI flapping.
- Detector: only evaluate the falling edge when dry_time is explicitly
present and parseable; skip otherwise without updating state.
Step 0 empirical test on 2026-05-20 disproved the "CLI cannot re-slice a
3MF for a different printer" assumption: feeding an 18-color H2D-bound
Trent900.3mf to the X1C bundle via /slice produces valid X1C G-code in
1.8s, with bed (256x256), kinematics, nozzle count, machine_start_gcode,
and bed_exclude_area all coming from the target bundle.
- SliceModal: drop !printerMismatch from isReady; remove the banner and
the sourcePrinterModel / printerProfileName / printerMismatch state
entirely. Cross-printer slicing is now indistinguishable from a normal
slice; the picker already shows the target printer.
- Remove slice.printerMismatch from all 8 locales.
- API cleanup: drop source_printer_model from /library/files/{id}/plates
and /archives/{id}/plates responses, drop the field from
frontend/src/types/plates.ts (PlateMetadata + LibraryFilePlatesResponse),
delete extract_source_printer_model_from_3mf from threemf_tools.py and
its 6 unit tests. Zero remaining consumers.
- i18n discipline cleanup in SliceModal.tsx (same drop): strip every
inline English defaultValue / positional fallback from t() calls (22
sites). Add slice.bundle / slice.bundleNone / slice.bundleAllRequired
to all 8 locales — they had no entry in any locale file and were being
served from the inline English fallback for every non-English user.
- Tests: rewrite the mismatch-warning test to assert "no banner, Slice
enabled" when models differ (regression guard); delete 2 obsolete
tests covering gate states that no longer exist.
Reporter on Postgres + Spoolman saw weight never decremented after
prints. Traced to _report_spool_usage_for_slots calling only
client.find_spool_by_tag() — which returns None when extra.tag is empty.
Non-RFID spools assigned via the Bambuddy UI intentionally leave
extra.tag empty (per #1457 — we don't want fallback tags polluting
Spoolman), so tag-less spools never got matched and weight tracking
silently no-op'd. The tracker never consulted the local
spoolman_slot_assignments table that has the binding.
Adds _resolve_spool_id_via_slot_assignment() as stage 2 of the
resolution chain. Stage 1 (existing tag-lookup) wins when present so
RFID auto-sync remains unchanged. (ams_id, tray_id) derived from
global_tray_id via the existing _global_tray_id_to_ams_slot helper,
so external slots and AMS-HT slots resolve correctly. Threaded
printer_id through the three callers (partial G-code, partial linear,
final-usage report). Resolution path is logged ("via tag" vs "via
slot-assignment") so support bundles confirm the fix is live.
extra.tag is deliberately NOT auto-populated — that would re-introduce
the exact pollution #1457 cleaned up. Slot-assignment table is the
source of truth for non-RFID; extra.tag is reserved for hardware RFID.
Reporter on a P1S with non-RFID spools saw an old, almost-empty spool in
the AMS hover card's "Spulen-ID" block while the "Zugewiesen" block
correctly showed the freshly assigned full spool. Two layers compounded:
(1) Non-RFID slots fall back to a deterministic per-slot tag
(hash(serial) + ams_id + tray_id). The Link / Assign routes wrote
that tag to Spoolman extra.tag but never cleared it from the
previous holder on re-binding.
(2) The frontend's hover-card resolver preferred the (stale) tag-link
over the user's explicit slot-assignment. Same precedence bug in
SpoolBuddy's fill-bar resolver and slot-action picker.
Frontend: swap precedence at 5 sites — slot-assignment outranks tag-link
everywhere. FilamentHoverCard's existing match-dedupe then collapses the
two "Open in Inventory" buttons back into one.
Backend: new _clear_stale_tag_links() in spoolman_inventory.py, called
from POST /spoolman/inventory/slot-assignments (with the slot's
deterministic fallback tag) and POST /spoolman/spools/{id}/link (with
the literal tag being bound — works for RFID and fallback). Best-effort:
Spoolman 5xx and per-spool patch failures log + continue, never wedge
the bind. get_fallback_spool_tag_for_slot promoted to a public helper
mirroring the frontend's signature exactly.
Two bugs in one report, both shipped here.
(1) Popover positioning. The flame-icon onClick on PrintersPage
computed popover position as a fixed { top: rect.bottom + 4,
left: Math.max(8, rect.right - 240) } with no viewport-overflow
check. The flame icon sits at the bottom of the AMS info section
on the printer card, so on most realistic viewports
rect.bottom + 4 + popover_height (~320px) overruns viewport.height
and the popover renders partially or entirely off-screen with the
Start button unreachable. Reporter worked around it via DevTools to
confirm the popover was actually there, just clipped.
Extract a computePopoverPosition() helper in utils/popoverPosition.ts:
- defaults to below + right-aligned to the trigger (preserves the
original visual layout when there's room),
- flips ABOVE the trigger when below would overflow AND above fits,
- stays below in the degraded case (popover taller than viewport) —
at least the top is visible and the user can scroll inside; flipping
to a top-clipped position would lose the action buttons too,
- clamps the left coordinate so a trigger near either viewport edge
can't push the popover off-screen horizontally either.
Both PrintersPage callsites (compact AMS row at :3498 and dual-nozzle
layout at :4011) route through the helper.
(2) Diagnostic logging for the silent-drying-ignore. Reporter's
support bundle shows the printer receives every ams_filament_drying
command (P1S 01.10.00.00 firmware, AMS-HT at ams_id=128) and ACKs
each one, but the AMS info field never changes — drying neither
starts nor stops on Bambuddy's request, while pressing Start on the
printer's touchscreen works immediately. The command JSON matches
the format documented as working on H2D, all required fields present.
Diagnosing the silent rejection needs the printer's actual response
payload — result/reason — but bambu_mqtt.py:918 was only logging the
response command name, not the body. The existing extrusion_cali_* /
ams_filament_setting debug path at :919-920 was the template; this
PR extends it to ams_filament_drying at INFO level (not DEBUG like
its siblings) because drying responses are rare (user-initiated only)
and INFO ensures the body lands in support bundles by default without
the user having to bump log level first. Paired with an outgoing-side
INFO log inside send_drying_command that captures the full wire JSON,
so the next bundle has both halves of the conversation.
No guessing on the command-side. Mutating a field that matches the
documented-working H2D shape (e.g. flipping close_power_conflict)
could break currently-working installs. When the reporter retries on
this build and re-attaches a bundle, the rejection reason is visible
and the command-side fix follows from real data.
The pre-insert MQTT probe added in 0.2.4.2 (b51598ea) had two bugs that
compounded on P1S firmware specifically:
1. Fixed 2-second sleep was too short. P1S broker + TLS handshake
routinely needs 3-5s to surface CONNACK on a cold MQTT session (same
firmware family with the documented "broker stops publishing but TCP
stays alive" quirk at bambu_mqtt.py:3181), so the probe falsely rejected
a printer that would have connected fine. H2C's broker is snappier and
cleared the 2s window without trouble — which is why the reporter's
H2C added without issue and only the P1S misbehaved.
2. client.disconnect() ran synchronously on the asyncio thread.
BambuMQTTClient.disconnect() ends in paho's loop_stop() which joins
the network thread; if that thread was still mid-TLS-handshake to the
slow P1S socket when teardown ran, the join blocked the asyncio thread
for as long as the handshake took to complete or fail. POST /printers
wedged, every other HTTP request queued behind it, Docker healthcheck
timed out — user-visible symptom: "the container hangs."
Fix:
- Replace the fixed sleep with a polling loop (8s budget, 200ms tick,
early-returns the moment state.connected flips True). Slow brokers
get the headroom they need; happy-path connects still finish in
~1-2s. Constants exposed as PROBE_TIMEOUT_SECONDS / PROBE_POLL_
INTERVAL_SECONDS class attributes so tests can dial them down.
- Move client.disconnect() to await asyncio.to_thread(...) so paho's
thread-join can never block the event loop.
The empty-card-report-prevention goal of the original probe stays
intact: a genuinely wrong access code still results in connected=False
after the 8s budget, the 400 with code=printer_connection_failed
still fires, the row is still never persisted.
PrintLogEntry.failure_reason is captured once at print-completion time
(main.py:3641) by copying archive.failure_reason — which is NULL while
the user hasn't classified the failure yet. The PATCH /archives/{id}
route then writes only to print_archives via a generic setattr loop,
so the log entry stays NULL and failure_analysis.py keeps grouping the
print as "Unknown". Same desync hits status — flipping it in the modal
never reached the entry either.
Mirror failure_reason and status from the PATCH payload to the latest
PrintLogEntry for that archive (highest id). Latest-only because
archive.failure_reason / status already reflect the latest run's outcome
(each reprint clears the archive value at main.py:2195 and rewrites it
at completion), so the Edit Archive modal is implicitly editing the
latest run — reprints of an archive that succeeded on the second attempt
keep the earlier failed run's original classification intact.
Scoped to those two fields only. cost / print_name / printer_id stay
unmirrored because per-run values legitimately diverge from archive
ones (partial-print cost on a failed run vs source archive's full-print
cost — see _compute_run_filament_grams at main.py:596).
Python 3.13 negotiates TLS 1.3 by default. The P2S firmware 01.02.00.00
vsFTPd build doesn't tolerate TLS 1.3's async session-ticket model on
the FTPS data channel — session resumption races, the data channel gets
torn down mid-stream, uploads land truncated at a chunk boundary, and
the printer replies 426 instead of 226. Visible to the user as "unable
to parse 3mf file" 30 s into the print.
Capping the SSL context's maximum_version to TLS 1.2 makes session
resumption synchronous and uploads complete normally.
Follow the per-model pattern established by camera_profiles.py in the
#1395 follow-up: add backend/app/services/ftp_profiles.py with a frozen
FTPProfile dataclass and a per-model registry. Only P2S (display name
+ N7 SSDP code) gets the cap today. X1C, H2D, P1S, A1 stay on negotiated
TLS 1.3 — the maintainer's dogfooded printers see zero behaviour change.
The snapshot-diff strategy in _scan_for_timelapse_with_retries needs
_timelapse_baselines[printer_id] populated at print start so the
completion-time scan can find the new MP4 by set-difference (mtime is
unreliable — LAN-only printers don't sync NTP).
The baseline-capture call was only in on_print_start's new-archive branch.
Queue / VP-dispatched / reprinted jobs take the expected-archive branch
which returns earlier, so the dict stayed empty and the completion-time
scan fell into the "take baseline now" fallback that snapshots after the
new file has already landed — no diff ever matches.
Extract the snapshot into _capture_timelapse_baseline_at_start and call
it from both branches.
PR #1434 CI flagged 5 B402 (ftplib import) in test_bambu_ftp.py and 2
B108 (hardcoded /tmp) in test_print_start_assigns_printer_id_to_vp_archive.py.
Both are intentional in tests: the FTP client tests need real ftplib
exception classes to construct mock 426 responses, and the /tmp path is
a MagicMock attribute never written to. Marked with `# nosec B402` /
`# nosec B108` plus a one-line justification each, matching the
convention from c2630399.
Reporter — the same person who originally requested the labels
feature in #809 — discovered that the ams_30x15 preset's 30x15 mm
dimension didn't actually fit any variant of the MakerWorld AMS
Filament Label Holder (model 752566) it advertised. Two new
presets replace it:
- ams_holder_74x33 (74 x 33 mm) matches the printable label STL
bundled in the MakerWorld project
- ams_holder_75x55 (75 x 55 mm) fits the cardstock-insert variant
the reporter validated on bench
Both cross the 20 mm height threshold so they land in the roomy
layout branch — swatch on the left, QR on the right, multi-line
text (brand, material, hex code, spool ID) in the middle. The
old 30x15 mm preset couldn't fit a QR code; the new ones do.
No DB migration: the preset name was never persisted. Callers
scripting the old ams_30x15 value get a clean 422 at the route's
Literal validator with the new valid values listed.
i18n: replaced inventory.labels.templates.ams.{label,hint} with
amsHolderSmall and amsHolderLarge across all 8 locales with real
translations; parity guard cleaned of the stale English-fallback
cognate entries. Parity holds at 4856 leaves per locale.
Tests: backend label renderer + integration tests cover both new
presets; LabelTemplatePickerModal test updated for the 6-button
grid and the new template value in the API-call assertion.
VP-queue archives are created with printer_id=None at queue-add
time because the scheduler hasn't picked a printer yet (and even
for explicit-printer queue items, the archive predates dispatch).
on_print_start's expected-archive branch updated status,
started_at, and subtask_id but never assigned printer_id, so
VP-queue-dispatched archives stayed permanently unassigned.
That broke every UI/API path gated on archive.printer_id —
critically the post-print "Scan for timelapse" action: the
H.264 file is on the printer's SD card and reachable via the
file browser, but the archive's scan endpoint refused the request
and the button stayed greyed out forever.
One-line fix: archive.printer_id = printer_id in the
expected-archive branch. Guarded against clobbering an
already-correct value so library-file queue items (which create
their archive with the printer pre-assigned) are idempotent.
Cover endpoint had no negative cache: when every FTP path returned
550 for a print whose 3MF wasn't on the printer (typical SD-card
print), each frontend refresh re-ran the full 8-path fan-out. Add
_cover_404_cache keyed by (subtask_name, view_key) and short-circuit
to 404 on hit; clear alongside _cover_cache on print start. Only
populated on genuine 404 paths, not transient FTP errors, so flaky
network doesn't lock out future retries.
GitHub update-check had no backoff on 403 rate-limit. Add module-
level _github_rate_limit_until plus three helpers; check before
every api.github.com call in /updates/check and
_discover_target_release. Read X-RateLimit-Reset from the 403 with a
1-hour fallback when the header is absent and a 60-second floor to
guard against container/GitHub clock skew. Route surfaces
retry_after_seconds so the UI can display real wait time.
The "ffmpeg didn't terminate gracefully" line the reporter quoted
is the standard SIGTERM/SIGKILL pattern in camera.py and unrelated
to the FTP loop; it goes away on its own once the cover endpoint
stops hammering the printer.
Previous daily build (1fac0276) tightened the post-STOR voidresp
handler to fail on any ftplib.Error, stopping Bambuddy from
sending a print command for a truncated 3MF. Reporter
(@enjoylifenow on a P2S) then confirmed — after a clean SD-card
filesystem check, reformat, and power cycle — that v0.2.4.1
worked on the same hardware. That proves the 426 returned by
this firmware revision is noise: the TLS data-channel close
races the 226 confirmation, server reports failure, file is in
fact on the SD card.
Reverting wholesale would re-introduce the silent-truncation
bug from the original fix. Narrow the rule instead: after an
ftplib.Error from voidresp, run an FTP SIZE against the upload
path. SIZE matches the local file size → warn and proceed
(the reporter's case). SIZE mismatch, or SIZE itself raises →
fail loudly with full diagnostics (the original tightened
behavior — preserved).
Applied identically to upload_file() and upload_bytes() so the
A1-compatibility manual-transfer path is covered.
Tests: two regressions from the previous round renamed and
split into intact / truncated / size-check-fails. Intact-file
tests inject SIZE explicitly because pyftpdlib only flushes on
a clean voidresp — which can't happen when we monkeypatch
voidresp to raise. Docstring spells that out. 87 FTP unit tests
green; 118 FTP-touching tests across unit+integration green;
ruff clean.
The View-Timelapse-greyed-out behavior #1417 was originally
about stays untouched; once the reporter confirms upload
reliability is back, that diagnosis continues on a healthy
install.
Two-part fix for the #1322 follow-up by @RosdasHH.
Data layer.
The previous narrow heuristic in printer_manager.py only caught
the bare {"id": N} payload firmware sends right after a printer
restart. In steady-state operation — and on the more common
post-Reset-Slot path on P1S and A1 Mini BMCU — firmware sends a
populated payload and signals emptiness via the tray_exist_bits
bitmask. We already parse that bitmask and use it to wipe stale
tray_type / tray_color / tag_uid fields, but never touched the
state field, so downstream readers (printers.py API serializer,
inventory.py's tray_state in {9, 10} short-circuit, AMS card)
saw state: null and had to guess from absent payload fields.
Fix lifts tray["state"] = 9 (int — not "9"; inventory.py:1358
uses == not `in {...}` so a string would silently miss and the
reporter's deadlock would come back) to the outer `if not
slot_exists` branch, so the bitmask path now writes the
canonical "no spool" code for every empty slot regardless of
stale fields. The narrow heuristic in printer_manager.py:797
stays as belt-and-suspenders for any MQTT path that doesn't
flow through _handle_ams_data.
UI layer.
With the data flow now consistent, the AMS slot card renders
physically-empty slots distinctly from reset slots, per
reporter's mockup. New helper getEmptySlotKind(tray) returns
"physical" (state ∈ {9, 10}), "reset" (any other empty state),
or null (loaded). The inline label below the slot circle reads
"Empty" for physical and "Reset" for reset; pre-fix both showed
an em-dash. FilamentSlotCircle gains an emptyKind prop that
picks a quieter dashed border colour for reset slots so the
visual hierarchy reads loaded > reset > physically empty.
EmptySlotHoverCard gains a kind prop and switches between
"Empty slot" and "Slot reset — no spool assigned".
Three independent root causes behind the divergences the reporter
flagged after the archived-spool fix shipped — fixed together.
(1) Filament Used vs Total Consumed.
_compute_run_filament_grams returned the slicer estimate for completed
prints even when inventory had measured the actual AMS weight delta.
That made Stats and Inventory two different sources of truth: Stats
showed slicer-estimate grams, Inventory showed AMS-tracked grams, and
the two never agreed. Reordered the helper so the tracked spool delta
(same source that drives weight_used behind Total Consumed) takes
priority for every status. Slicer estimate stays as the fallback when
no inventory was tracked; partial-progress scale stays as the fallback
for failed/cancelled with no tracker. The _run_cost block right next
to it was already tracker-first; only filament_used_grams was
inconsistent.
(2) Printer Stats By Time vs Quick Stats Print Time.
/archives/slim only set actual_time_seconds when status == "completed".
For failed/cancelled rows the frontend fell back to print_time_seconds
(the slicer's full-print estimate — wrong number for a print that
failed at 15%). Quick Stats already summed elapsed duration across
all statuses, so the two halves of the page disagreed by the
(estimate - actual-elapsed) gap on every non-completed event. Dropped
the completed-only gate; failed/cancelled now report measured elapsed.
(3) Success Rate %.
Was successful / (successful + failed), excluding cancelled / stopped
from the denominator. With "Total Prints: N" displayed right above
the gauge that produced confusing numbers — 4 successful, 0 failed,
48 cancelled showed 100% out of an apparent 52 prints. Switched to
successful / total_prints — matches the count the user reads from
the widget header.
Editing a Spoolman spool used to mint a brand-new filament every time
a match-key field (subtype/material/brand/color_hex) changed, orphan
the previous one, and re-link the spool. The reporter ended up with
dozens of duplicate "Amazon Basics / PLA Glow" filament rows.
PATCH /spoolman/inventory/spools/{id} now:
- Reuses the current filament_id when no filament-shaping field
changed (a note/weight_used edit never touches the catalogue).
- PATCHes the existing filament in place when it's a singleton
(only this spool points at it, archived spools included).
- Falls back to find_or_create_filament only when the filament is
genuinely shared with another spool.
Mirrors internal-inventory behaviour where editing a spool updates
the thing the spool points at instead of proliferating new entities.
Step 2 of the camera architecture overhaul agreed after #1395. When
the camera viewer hits its error state OR before a print at any
time, a Diagnose button runs a staged check against the printer and
renders the result inline: which stage failed, how long it took,
and a translated remediation hint. Cuts off the "user opens a
'camera broken' ticket → ask for support bundle → triage" loop at
the user's screen.
Backend
- New `backend/app/services/camera_diagnose.py` orchestrator with
CameraDiagnoseResult / CameraDiagnoseStage dataclasses.
- New POST /printers/{id}/camera/diagnose route in camera.py.
- Stages:
tcp_reachable — TCP socket open to 322 (RTSP) / 6000 (chamber)
with 3 s timeout. Distinguishes timeout, refused, and host-
unreachable into distinct summary codes so the frontend can
show a precise remediation (firewall vs LAN-only off vs
wrong IP).
first_frame — captures one JPEG end-to-end via the existing
capture_camera_frame_bytes pipeline. Auth + RTSP handshake +
first keyframe collapse into one stage; the user-facing
answer is the same regardless of which sub-layer failed.
- Live-stream shortcut: when a viewer is currently watching the
camera with a buffered frame < 10 s old, the diagnostic skips
the real test and returns live_stream_active_healthy. Opening a
fresh socket would kick the live viewer off on single-camera-
connection firmwares (the #1348 reconnect-storm trigger), so we
trust the real-world evidence instead.
- Response surfaces protocol, port, and profile name for support
triage — lets us ask "what does your modal say?" instead of
"send the support bundle".
Frontend
- New CameraDiagnoseModal renders one row per stage with green-
check / red-X / grey-skipped icons, the per-stage duration in
ms, a remediation banner styled by overall status, and a Run
again button.
- Two entry points:
1. The viewer's error overlay grows a Diagnose button next to
Retry. Retry stays the primary action; Diagnose is the
escape hatch for users who can't see what's wrong.
2. A stethoscope icon in the viewer's always-visible control
bar, between Refresh and Fullscreen. Pre-flight testing
("did my firmware update break the camera?", "is the
camera up before I send a print?") doesn't require waiting
for the stream to fail first.
- Also lifted the previously-hard-coded "Camera unavailable" /
"Retry" strings into camera.unavailable / camera.retry so the
error UI is fully translated alongside the new keys.
Reporter on a P2S running firmware 01.02.00.00 saw the camera connect
for a few seconds then time out, repeating. P1S on the same install
worked fine — different protocol (chamber-image port 6000 vs RTSP via
ffmpeg).
The P2S RTSP path was running ffmpeg with `-probesize 32
-analyzeduration 0`, tuned for X1/H2 fast startup. The P2S's slower
keyframe pacing means ffmpeg can't lock onto the stream within 32
bytes — its own stderr says "consider increasing probesize" before
giving up after ~2s. Bambuddy reconnects, cycle repeats.
Instead of bumping the globals (which would regress every other RTSP
model's startup latency), this lifts the per-model tuning into a new
`camera_profiles` registry. CameraProfile dataclass holds the
previously-global knobs (probesize, analyzeduration, rtsp_reconnect_max,
rtsp_reconnect_delay, plus an extra_ffmpeg_input_args hook for future
per-model flags). get_camera_profile(model) returns the model's profile
or DEFAULT_PROFILE.
Default profile preserves the historical X1/H2 fast-startup values
verbatim — X1, X1C, X1E, X2D, H2C, H2D, H2D Pro, H2S all see no
behaviour change. P2S is the only override:
P2S: probesize=1_000_000, analyzeduration=500_000
SSDP internal codes (N7→P2S) resolve via an alias map so the camera
path works during the early-connect window before the display name
is settled.
This is the first step of the camera-architecture overhaul agreed
after #1395. Adding the next quirky model is a config entry, not
another module-level constant.
Reporter sliced in OrcaSlicer with timelapse on, sent the job to a VP
queue, started from the queue, and got no timelapse video. Their
dispatch chain itself was correct (queue item -> scheduler -> MQTT
command honors `timelapse`); the gap was at queue-add time.
The VP's `_add_to_print_queue` reads `default_timelapse` (and the four
other print-option settings) from the workflow settings card. That was
introduced in #1235 to stop column-level defaults from winning. But it
also discarded the slicer's actual choice carried on the MQTT
`project_file` command, which all the slicers (Studio / Handy / Orca)
ship as `timelapse: true|1`. Result: a user with the new-install value
`default_timelapse=false` had to either flip the global setting or
edit every queue item by hand, even though their slicer's "Print
options" UI clearly said "record timelapse".
Investigation went wider than #1403 because Martin's hypothesis was
"the print options modal isn't respected either." Cross-checking
86 captured P1S `project_file` commands across the support packages
shows 46 from the queue scheduler and 33 from background_dispatch
emitting `"timelapse": true` correctly to real printers - the modal +
re-print path is intact end-to-end. The slicer-side gap was the only
real bug. Two unrelated dead-code issues turned up in the same dig and
are folded in below.
Fix (VP queue inheritance)
- `on_print_command` in the VP manager now stashes the slicer's
project_file dict keyed by filename, then signals an asyncio.Event.
- `_add_to_print_queue` checks the dict first; if empty, creates the
event and waits up to 2 s for it before reading the settings
fallback. Each option flows through per-field - slicer value wins
if present, else the existing settings default (so users who
explicitly set `default_timelapse=true` in their VP workflow card
still get that on slicers that don't send a print command).
- MQTT field naming preserved exactly: `bed_leveling` (single L) on
the wire stays mapped to `bed_levelling` (double L) on the Bambuddy
column. Integer 0/1 from H-family slicers and bool true/false from
P1/X1 slicers both coerce via `bool()`.
- Capture is gated on `mode == "print_queue"` so immediate / review /
proxy modes keep their pre-fix no-op `on_print_command` and don't
accumulate stashed entries over the VP's uptime.
- Wait is also skipped when there's no MQTT server attached
(`self._mqtt is None`), so unit tests that invoke
`_add_to_print_queue` directly don't pay the 2 s tax.
- Capture is consumed on use so the dict stays bounded.
- `printer_manager.get_status(...).get(...)` against a `PrinterState`
dataclass that has no `.get()` method.
- Every print option discarded (timelapse, bed_levelling, AMS mapping).
The route 500'd before ever reaching the printer. Rewritten to mirror
`POST /print-queue/{item_id}/start`: clear `manual_start=False` on the
next pending queue item and let the scheduler dispatch with the
queue's stored options intact. Response shape preserved.
Side-bug b: vibration_cali default drift in background_dispatch
- `ReprintRequest.vibration_cali` and `FilePrintRequest.vibration_cali`
both default to `True` (matches Bambu Studio behavior for X1/P1).
- Both `_process_job` call sites read
`job.options.get("vibration_cali", False)`.
Cosmetic today because the frontend always sends the field, but a
latent landmine for any future caller that bypasses the schema. Both
sites flipped to `True`.
Reporter saw a 544 g spool jump to 1000 g after pressing the eraser.
"Spools and remaining weights are not changed" - the dialog promised
this; the implementation did the opposite. Root cause was an
architectural conflation: `weight_used` did double duty as the
resettable "consumed since tracking started" counter AND as the basis
for the displayed remaining (`label_weight - weight_used`), so zeroing
it correctly cleared the stat but unavoidably reset remaining to full.
Spoolman has separate `used_weight` and `remaining_weight` fields, so
the API call there was correct - but Bambuddy's frontend was also
computing remaining as `label_weight - weight_used` for Spoolman
spools (ignoring Spoolman's real `remaining_weight` field), so the
same visual bug bit there too. Inventory-mode parity required fixing
both halves in one drop.
Internal mode
- New `weight_used_baseline` column (Float DEFAULT 0) on `spool`.
- Reset stamps `baseline = weight_used` and leaves `weight_used` alone.
- Displayed consumed = `weight_used - baseline`; remaining =
`label_weight - weight_used` (unchanged).
- Subsequent prints continue to grow `weight_used`, so the resettable
counter naturally tracks post-reset delta and remaining keeps
decrementing across the reset.
Spoolman mode
- `_map_spoolman_spool` now reads Spoolman's `remaining_weight` field
and returns a synthetic `weight_used = label - remaining` so the
frontend's remaining calc matches Spoolman's real stored value;
`weight_used_baseline = synthetic - real_used_weight` so the consumed
counter (`weight_used - baseline`) matches Spoolman's `used_weight`.
- Fallback path (no `remaining_weight` set) preserves the old behavior.
- Related fix: `update_spool` (Spoolman PATCH) was deriving the default
`weight_used` from `used_weight`, so editing unrelated fields AFTER
a reset would patch Spoolman with `remaining_weight = label - 0 =
label`, trampling the real value. Now derives from
`remaining_weight` so non-weight edits preserve physical state.
Frontend
- `InventoryPage` `totalConsumed` aggregate switched to
`Math.max(0, weight_used - (weight_used_baseline ?? 0))`.
- `ForecastPanel` `computeDeltaRate`, `totalUsedG`, and the per-spool
"consumed" table cell got the same treatment so forecast and
inventory aggregates stay coherent across a reset.
- `?? 0` keeps pre-migration installs rendering correctly until
`init_db()` runs the idempotent ALTER TABLE.
Migration
- `ALTER TABLE spool ADD COLUMN weight_used_baseline REAL DEFAULT 0`
via `_safe_execute` - SQLite and Postgres both accept it; verified
end-to-end on Postgres 16.
Several support reports traced back to one root cause: a mistyped access
code in Add Printer left an empty card on the dashboard. POST /printers/
was persisting the row first, then firing connect_printer() fire-and-forget.
Now we test_connection() BEFORE the insert; failure returns HTTP 400 and
the row is never written.
Structured error response -- detail={"code", "message"} -- so the toast
shows the localized message instead of the English fallback. New
ApiError.code field on the frontend; printers.toast.connectionFailedNotAdded
While auditing real-world Bambuddy backup repos on GitHub I found
several left public. That's a serious leak: the settings backup only
filters bambu_cloud_token and auth_secret_key, so mqtt_username,
mqtt_password, ha_token, prometheus_token, bambu_cloud_email,
external_url, and the printer access codes (via K-profiles) were going
to whatever visibility the user picked.
Hard guard at every save and re-checked on every push:
- POST /github-backup/config and PATCH /github-backup/config (when URL,
token, or provider changes) run a connection test internally and
return 400 unless is_private comes back True.
- run_backup() re-checks before each scheduled or manual push, so a
repository that flipped from private to public gets a clear
"Backup aborted: the target repository is no longer private" failure.
Each provider's test_connection now returns is_private (GitHub /
Gitea / Forgejo read data.private, GitLab reads visibility=="private";
"internal" is treated as non-private). None means "couldn't determine"
and is also rejected -- safer to fail closed.
Frontend renders visibility inline on Test Connection: green check when
private, red warning panel listing every credential at risk when public,
yellow when unknown.
---
ui(github-backup): show save-failure messages inline on the card
The new "repository is not private" rejection message is ~250 characters
listing every credential the backup carries (MQTT password, HA token,
Prometheus token, Bambu Cloud email, printer access codes), which clips
badly in a toast.
Both the initial-setup save and the debounced autosave now stash the
backend's error message into a saveError state and render it as a red
inline banner above the test-result block, with whitespace-pre-wrap so
the full message stays readable. The banner clears on success, on the
next save attempt, and when the user starts editing URL / token / provider
-- the three fields whose changes invalidate the privacy check -- so it
doesn't linger after the user has already addressed the cause.
Short success toasts (Settings saved, Token updated, Backup enabled) are
unchanged.
First cut of this action only wired the built-in inventory path, so the
eraser buttons vanished when the user switched to Spoolman mode. Mirror
the endpoints on the Spoolman router:
- POST /spoolman/inventory/spools/{id}/reset-usage
- POST /spoolman/inventory/spools/reset-usage-bulk
Both route to a new SpoolmanClient.reset_spool_usage() helper that PATCHes
/spool/{id} with used_weight=0. The bulk variant keeps the same typo-wipe
guard (rejects empty/missing spool_ids), and individual Spoolman failures
are logged + counted out without aborting the batch.
InventoryPage mutations now switch on spoolmanMode to pick the right
client method, and the three "spoolmanMode ? undefined : ..." gates on
the eraser buttons are gone.
After #1378 moved Quick Stats to print_log_entries, six widgets and
Failure Analysis still iterated the archive list. That made reprints
multiply event-based widgets while leaving archive-based ones unchanged,
and made hard-deleted archives drop from archive-based widgets while
their orphan events kept feeding Quick Stats.
Swap the data source in two places:
- GET /archives/slim now reads PrintLogEntry, LEFT JOINs the archive for
the sliced print_time_seconds estimate, prefers PrintLogEntry's own
duration_seconds as the measured-time field. StatsPage is the only
caller -- every widget realigns in one step.
- FailureAnalysisService swapped from PrintArchive to PrintLogEntry for
every aggregation. project_id filter still resolves through archives
but counts matching events.
Conftest archive_factory now syncs the synthesized event's created_at
with the archive's so backdated test data survives the change.
bambu_ftp.upload_file (and upload_bytes) wrapped the voidresp() call in a
broad "except Exception: log warning and proceed" because H2D printers
can take 30+ seconds to send the 226 and we don't want to fail on that.
But the same handler was swallowing ftplib.error_temp (e.g. 426 "Failure
reading network stream") from buggy printer firmware, which explicitly
means the data stream was cut mid-transfer and the file on the SD card
is partial.
Bambuddy then sent the print command anyway, and the printer surfaced a
generic "unable to parse 3mf file" error 30 seconds into the print
attempt -- with nothing in the log on the user side to suggest the
upload had actually failed.
Split the catch: ftplib.Error subclasses (server-reported failure)
re-raise so the outer handler returns False; everything else (socket
timeout etc.) keeps the existing proceed-with-warning behaviour so the
H2D 226 tolerance survives.
Two regression tests patch _ftp.voidresp to raise error_temp("426 ...")
and assert both upload_file() and upload_bytes() return False.
The underlying P2S firmware / TLS-data-channel issue that triggers the
426 for the reporter is separate -- this change just stops Bambuddy from
hiding it.
Reporter @iitazz uploaded slicer output to Bambuddy, clicked Print,
and the printer rejected every job with "Printing stopped because
the printer was unable to parse the 3mf file". Support bundle showed
the stored library file ended in .gcode (not .gcode.3mf), and
background_dispatch.py appends ".3mf" to filenames that don't
already end in .gcode.3mf/.3mf — so raw gcode shipped to the printer
named .gcode.3mf and the firmware's 3MF parser choked. Same shape
also surfaced as "File is not a zip file" on Bambuddy's own plate
parser.
New validate_print_file_upload() helper in library.py runs at upload
time:
- Reject filenames ending in .gcode (but not .gcode.3mf) with a
clear message — Bambu printers need .gcode.3mf zip containers,
not raw gcode.
- For .3mf / .gcode.3mf uploads, verify body starts with PK\x03\x04
(ZIP magic); reject otherwise pointing at the slicer's "Export
Plate Sliced File" action.
Applied to every relevant upload route: POST /library/files (covers
File Manager + printer-card drag-drop), POST /archives/upload,
POST /archives/upload-bulk (rejects per-row so one bad file doesn't
abort the batch), POST /archives/{id}/source, POST /archives/upload-source.
Runs after _resolve_upload_destination so folder-permission errors
(403 readonly, 400 missing-path, 409 collision) still take precedence.
STL / image / other non-print uploads bypass the validator.
FileUploadModal frontend fix: the modal auto-closed after every
batch regardless of per-file results, so a 400 rejection was captured
but invisible. Now:
- Errors render inline as red text under the file row instead of
as a hover-only title tooltip.
- Modal stays open if any file ended with status='error', so the
user can read the backend's remediation message before closing.
- Successful-only batches still auto-close as before.
UploadModal (bulk archive) was already showing inline errors and
not auto-closing — no change needed there.
Reporter Kyobinoyo asked for the equivalent of the existing
print-finish auto-off but triggered when AMS drying ends.
Two new SmartPlug columns: auto_off_after_drying (default false),
off_delay_after_drying_minutes (default 10 — AMS chamber is hot
post-cycle so longer cooldown than the print-finish default of 5).
SQLite + Postgres migrations both idempotent.
Trigger lives in BambuMQTTClient — per-AMS _previous_dry_times
tracks the dry_time > 0 → 0 falling edge and fires a new
on_drying_complete(ams_id) callback. Plumbed through
PrinterManager.set_drying_complete_callback to
SmartPlugManager.on_drying_complete(printer_id, db), which walks
linked plugs and respects the per-plug toggle. Catches queue,
ambient and manual drying identically because it observes firmware
state, not scheduler intent.
Frontend: single "Auto Off After Drying" toggle + delay input on
the smart plug card, next to the existing print-finish auto-off
section.
Per-AMS plug routing (separate plug for AMS only, per-AMS targeting
on dual-AMS printers) deferred — Bambuddy's plug model is
plug→printer, so the trigger fires whenever any AMS on the linked
printer finishes a cycle.
Reporter IndividualGhost1905 followed up after the #1378 / #1343
backfill landed and pointed at the next inconsistency: the per-
archive delete dialog has had a "Also remove this print from Quick
Stats" checkbox since #1343, but the "Purge Old" button and the
scheduled daily auto-purge sweeper both ignored that choice and
hard-deleted unconditionally. From the user side this looked like
"automatically deleted from statistics without any warning" — half-
true, and the inconsistency was real either way.
The actual current shape (before this fix):
- POST /archives/purge -> archive_purge_service.purge_older_than
-> ArchiveService.delete_archive (hard). Archive row dropped.
Linked PrintLogEntry rows have ON DELETE SET NULL so they
survive as orphans with archive_id=NULL. Quick Stats keeps the
filament / cost / energy contribution because the log rows are
still there, but the archive-list-iterating widgets (Filament
Trends, By Material, Color Distribution, Printer Stats) lose
the row, and Time Accuracy loses its join target. Visibly
inconsistent.
- Scheduled _maybe_run_auto_purge -> same code path, same effect.
- Single-archive DELETE /archives/{id} -> already takes
purge_stats=true|false (default false=soft) and routes either
soft_delete_archive (keeps everything, flips deleted_at) or
deletes PrintLogEntry rows first + hard-deletes archive.
The fix threads the same purge_stats flag through every bulk surface
with soft as the default, matching the single-archive default:
Backend:
- archive_purge_service.purge_older_than(..., purge_stats=False)
-> per-row soft_delete_archive when False, per-row
PrintLogEntry deletion + delete_archive when True. Each runs in
its own session (same pattern the sweeper already used).
- preview_purge gains the same kwarg so the eligible-count
matches what an actual run would touch: soft mode excludes
already-soft-deleted rows, hard mode counts them as eligible
for promotion.
- get_settings / set_settings now persist archive_auto_purge_stats
(default False). _maybe_run_auto_purge reads it on every tick.
- ArchivePurgeRequest / ArchivePurgeResponse / ArchivePurgeSettings
schemas extended.
- Route /archives/purge accepts the body flag, /purge/preview
accepts the query param, /purge/settings GET + PUT echo the
setting.
Frontend:
- "Purge old archives" modal: new "Also remove from statistics"
checkbox under the preview, unchecked by default. Plumbed into
the preview query key + the execute mutation.
- Settings -> Archives auto-purge card: matching toggle next to
the days slider, disabled when auto-purge itself is off.
- api.previewArchivePurge / api.executeArchivePurge accept the
flag; ArchivePurgeSettings type gains purge_stats.
- All 8 locales (en, de, fr, it, ja, pt-BR, zh-CN, zh-TW) get
new purgeStatsLabel / purgeStatsHint / purgeStatsDescription
keys, plus rewritten effect / warning copy in archivePurge and
archiveAutoPurge to reflect that the default no longer
"permanently removes from the database" but instead hides the
row + removes files while keeping Quick Stats intact. i18n
parity check clean: 4814 keys across all 8 locales, no fallback.
Behaviour change for existing users on auto-purge: the sweeper used
to hard-delete by default and now soft-deletes by default. After
the upgrade those installs start *preserving* more data in Quick
Stats rather than losing it — safer direction of the two, but worth
the explicit call-out. Anyone who wants the old behaviour ticks the
new toggle once and it persists.
Reporter vmhomelab ran a Print Queue VP against a P1S, opened
BambuStudio, and saw only the External Spool. Toggling Auto-Dispatch
(which restarts the VP) made AMS briefly appear, then it reverted to
defaults. Proxy Mode worked fine.
The earlier #1371 sticky-keys fix only handled one of two firmware
incremental-push shapes: it preserved cached `ams` when the incoming
push OMITTED the key entirely. P1S firmware (01.09.01.00) instead
sends incrementals with the `ams` key present but the inner `ams.ams`
array stripped — `{ams_status: 1, humidity: 2}` rather than
`{ams: [...], ams_status: 1}`. To the existing "key present? leave it"
check that read as "no need to preserve," so the bridge cache got
overwritten with the stripped blob, the slicer's next 1 Hz read saw
`ams` with no unit list, and BambuStudio fell back to its "no AMS"
default render. Toggling Auto-Dispatch restarted the VP and got a
fresh pushall through; the next P1S incremental stripped it again.
H2D rarely trips this because its incrementals typically don't carry
`ams` at all, so #1371 alone was enough — which is why H2D users
(including the project owner) didn't see the bug while P1S/A1 users do.
Fix: deep-merge the `ams` key inside the bridge cache. Mirrors the
structure Bambuddy itself already does in
`bambu_mqtt.py::_handle_ams_data` — scalar fields take the new value,
but the `ams.ams` array is merged unit-by-unit by `id`, each unit's
`tray` array is merged tray-by-tray by `id`, and units / trays the
incremental doesn't mention survive intact from the cached full
state. A tray-targeted incremental during a print
(`{ams: [{id: 0, tray: [{id: 0, state: 11}]}]}`) now updates that one
tray's state without dropping the other trays' tray_type / tray_color.
Helper added as `_merge_ams_dict` next to `_ip_to_uint32_le`, called
from the existing sticky-keys block when both prev and new carry the
`ams` key as dicts. Other sticky keys (vt_tray, net, ipcam,
lights_report, ams_extruder_map, mapping) keep the prior absent-only
preservation; only `ams` has the multi-shape partial problem worth
the merge complexity.
Reporter IndividualGhost1905 upgraded to 0.2.4.1 (which shipped the
per-event aggregation rewrite from #1378) and saw Quick Stats split
between consistent values (Total Prints, Print Time, Filament Used,
Energy, Success Rate matched the archive list) and zero-or-empty ones
(Filament Cost, Time Accuracy).
Root cause: #1378's migration added six columns to print_log_entries
- archive_id, cost, energy_kwh, energy_cost, failure_reason,
created_by_id - but never backfilled them. Pre-upgrade rows kept NULL
on all six. The new Quick Stats query sums PrintLogEntry.cost (gets 0
on legacy data); the time-accuracy query JOINs PrintArchive ON
archive_id (drops every legacy run from the average). Counts and the
pre-existing per-row fields (status, duration_seconds,
filament_used_grams) kept working - which is why some panels looked
right and others didn't.
Two-step backfill added inside run_migrations next to the existing
column-add block, as DML inside begin_nested() (not _safe_execute,
which is documented DDL-only):
Step 1: link each orphan log entry to its archive via
print_name + printer_id (highest archive id wins on
tiebreak - newest matches the overwrite-then-stop shape
pre-#1378 reprints left behind).
Step 2: copy archive.cost / energy_kwh / energy_cost onto the
latest matching log entry per archive, BUT only for
archives where no log entry yet carries a cost. That
second clause is the idempotency anchor and the
double-count guard for users running this after #1378
has already written cost-bearing rows for new runs -
those archives are left untouched.
Earlier reprints stay NULL, matching the "first/latest writes, rest
stay NULL" convention #1378 introduced for new prints. Sum across the
legacy reprint chain reproduces sum-of-archive-cost exactly, so Quick
Stats Filament Cost matches the pre-upgrade total instead of dropping
to zero.
SQL is plain ANSI - correlated UPDATE with LIMIT 1 in the SET
subquery, WHERE id IN (SELECT MAX(id) ... GROUP BY archive_id HAVING
SUM(CASE WHEN cost IS NOT NULL THEN 1 ELSE 0 END) = 0). Verified
end-to-end on SQLite (4 new unit tests in
test_print_log_backfill_migration.py: link-via-name, latest-run-gets-
cost, idempotent, skip-archives-with-any-costed-run) and against a
live postgres:16-alpine + asyncpg container (first-pass and second-
pass produce identical state).
The other widgets the reporter listed (Printer Stats, Filament
Trends, By Material, Success by Material, Color Distribution) iterate
the archives list on the frontend rather than calling /stats - they
read consistent pre-upgrade data and aren't part of this fix; the
inconsistency between them and Quick Stats resolves once the backfill
brings Quick Stats in line.
Reporter pgladel edited a spool's Color Name in Spoolman mode, hit
Save, and saw the value snap back to the subtype on the next read.
The earlier #1319 fix correctly handled the read/form-prefill half
(the color_name_is_synthesized flag, blank-on-synth form init), but
the write half assumed Spoolman has a `color_name` field on Filament.
It doesn't. Verified against the live FilamentUpdateParameters schema
on Spoolman 0.23.1 — the accepted fields are name, vendor_id, material,
price, density, diameter, weight, spool_weight, article_number,
comment, settings_extruder_temp, settings_bed_temp, color_hex,
multi_color_hexes, multi_color_direction, external_id, extra. No
color_name. Spoolman's PATCH happily returns 200 for
{"color_name": "Red"} and silently discards the unknown key, so
find_or_create_filament was either patching a void or creating
filament after filament with the same field-that-doesn't-stick (which
is what produced the "BB also created a bunch of new filaments"
duplicate trail on each save attempt).
The fix follows the same pattern as the existing BambuStudio slicer-
preset storage: persist color_name on spool.extra.bambu_color_name as
a JSON-encoded string, register the extra field via
ensure_extra_field before write (Spoolman 400s on unknown extra keys),
and read it back in _map_spoolman_spool with priority
extra > filament.color_name (forward-compat for any future Spoolman
release that adds the field) > subtype synth.
Dropped the now-dead color_name passing through
find_or_create_filament and create_filament — Spoolman would discard
it anyway and keeping the dead pipe risked the same confusion the
next time someone reads this code. The previous "match by name then
patch color_name" loop is gone; what survives is the name-match
resilience that lets an AMS-sync-created filament named "Glow" still
match the user-driven edit's composed "PLA Glow", which prevents
re-introducing the duplicate-filament trail.
The frontend form's color_name_is_synthesized handling is unchanged
— that part already worked.
Reporter MartinNYHC opened the Add Smart Plug dialog in HA mode, typed
a search prefix matching a multi-entity device (one switch.* plus
several sensor.*/binary_sensor.* siblings under the same friendly
name), clicked one of the non-switch siblings, and got a 422 on Save:
String should match pattern
'^(switch|light|input_boolean|script)\.[a-z0-9_]+$'
The screenshot confirms the bug shape — the X button next to the
"empty-looking" Select Entity field only renders when haEntityId is
truthy. So haEntityId was set, but selectedEntity (haEntities.find by
that id) returned undefined, so the input rendered the placeholder
text instead of the friendly-name display. That can only happen when
the user had earlier picked an entity whose domain is NOT in the
schema's allowed list, then the search cleared, the entity-list
refetched without a search param, and the refreshed list (filtered to
the default domains) no longer contained the user's pick.
Root cause was in HomeAssistantService.list_entities: when a search
query was present, the function bypassed the domain filter entirely
and returned matches across every HA domain. Offering a clickable
choice the schema can't accept is broken UX, and the cryptic Pydantic
pattern echo on save made it look like a backend/schema problem
rather than a search-permissiveness problem. Confirmed via git diff
that the smart-plug code path is unchanged between v0.2.4 and
0.2.4.1 — this has been latent since the script-domain commit in
February 2026, only noticed now because the reporter hadn't reopened
the modal in months.
Fix: always apply the allowed-domains filter ({switch, light,
input_boolean, script} — kept in sync with the regex in
backend/app/schemas/smart_plug.py:17). Search composes on top as a
substring match against entity_id or friendly_name, instead of
replacing the domain filter. Whitespace-only search strings now
fall back to the no-search behavior.
H2S is single-nozzle (nozzle_count=1 across 9+ stored support bundles
and the reporter's diagnostic) but had been added to the H-family model
gate in start_print_job. That single flag controlled both the firmware
bool->int format (legitimately needed for the whole H-family, including
H2S) and the dual-nozzle external-spool routing (correct only for actual
dual-extruder printers).
With no AMS attached and an external-spool slot (tray_id=254), the
dual-nozzle branch wrote ams_id=254 into ams_mapping2 instead of the
canonical 255 — exactly the failure the comment six lines above warns
against. Firmware rejected the dispatch with 07FF_8012 "Failed to get
AMS mapping table". The use_ams=False fallback was also being skipped
because the H-family bypass was meant for dual-nozzle routing.
A second site at bambu_mqtt.py:3987 and its sibling at kprofiles.py:119
detected dual-nozzle by serial prefix ("094", "20P9", "31B8B"). H2S
shares prefix "094" with H2D, so prefix detection misclassified it too.
Split the conflated flag into two:
- is_h_family — firmware format (int 0/1 for calibration fields).
Includes H2S. H2S firmware structurally accepted the current command
shape (failure was at AMS routing, not parsing), so the int format
stays for H2S.
- is_dual_nozzle — external-spool routing and use_ams gating. Excludes
H2S. Source-of-truth is the runtime _is_dual_nozzle flag set from
device.extruder.info, with a model-name fallback for the brief window
after connect before push data arrives.
The K-profile delete site and the kprofiles route now use the same
runtime+model check instead of serial prefix.
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.
