feat(vp): add archive name source toggle (metadata/filename) (#1152)
Slicer-uploaded archives picked up their display name from the 3MF's
embedded print_name (the creator-baked title); users who renamed a job
in BambuStudio's "Send to printer" dialog never saw that name surface
because the FTP filename was only used as a fallback when metadata was
empty.
Settings -> Virtual Printer now exposes an Archive name source toggle
(Metadata / Filename, default Metadata) that flips precedence in
ArchiveService.archive_print via a new prefer_filename_for_name param.
All four VP-sourced archive paths read the new
virtual_printer_archive_name_source setting and forward the flag:
_archive_file, _add_to_print_queue, POST /pending-uploads/archive-all,
POST /pending-uploads/{id}/archive.

fix(scheduler): post-dispatch hold prevents H2D Pro double-fire (#1157)
Multi-plate batches scheduled to the same H2D Pro were triple-dispatched
within ~60 s — observed in user logs as queue items 139/140/141 all
flipping to status='printing' even though the printer was still
digesting the first project_file (FINISH for 80-210 s before flipping
to PREPARE). The DB busy_printers seed at print_scheduler.py:145 was
empirically missing the in-flight items in this window; without
database access I cannot pin the exact why, but the guard is unreliable.
Add a defensive in-memory dispatch hold:
- _start_print captures (dispatched_at, pre_state, pre_subtask_id) per
printer
- check_queue augments busy_printers with any printer still inside its
hold window (60 s minimum cooldown, 180 s hard timeout)
- _watchdog_print_start releases the hold once it observes a state or
subtask_id transition (success path), or on the existing 90 s revert
(unhappy path), or on disconnect
Pure additive — alongside the existing seed query and _is_printer_idle.
Doesn't depend on DB row visibility or on_print_complete firing
correctly. Per-printer isolated. Watchdog kept as @staticmethod so the
existing 12 watchdog tests pass unchanged; hold-release calls go
through the module-level scheduler instance.

feat(slicer): live progress + filament discovery polish + OrcaSlicer warning
End-to-end live progress, two correctness fixes, and a UX warning around
the upstream OrcaSlicer bugs we discovered while testing.
LIVE PROGRESS
=============
Wire OrcaSlicer / BambuStudio's --pipe progress channel through the
sidecar -> Bambuddy -> persistent toast so a user-initiated slice shows
"{name} -- Generating G-code (75%) -- 47s" instead of just elapsed time.
The same wiring covers the SliceModal's filament-analysis preview slice
(the real slice that fires before profile picking, used to discover
which AMS slots an unsliced plate consumes) and the embedded-settings
fallback path triggered by Orca's --load-settings segfault on complex
H2D models.
- Sidecar (orca-slicer-api/bambuddy/profile-resolver, separate commit):
switch /slice from execFile to spawn, mkfifo per request, parse the
CLI's structured JSON progress events into a per-process
ProgressStore, expose GET /slice/progress/:requestId.
- Bambuddy backend: slicer_api.slice_with_profiles + slice_without_profiles
accept request_id + on_progress, spawn a 1Hz parallel poller that
forwards each snapshot via SliceDispatchService.set_progress(job_id,
...) onto the matching SliceJob; GET /slice-jobs/:id includes the
latest snapshot on every poll. The 404 from the early-race window
(POST fired before sidecar's progressStore.start) is treated as a
retry rather than terminal -- otherwise the poller bailed before any
progress could ever arrive.
- /api/v1/slicer/preview-progress/:requestId proxies the sidecar's
progress endpoint for the modal's filament-discovery flow (the
/filament-requirements call is server-originated; the browser can't
reach the sidecar directly).
- Frontend: SliceJobTrackerContext re-renders the persistent toast with
the new format when a useful progress frame is present, falls back
to elapsed-time-only when the sidecar hasn't emitted yet or doesn't
support progress. SliceModal.FilamentAnalysisSpinner generates a
per-(source, plate) UUID, polls the proxy at 1Hz, and mirrors the
inline spinner contents into a separate persistent toast so the
preview slice doesn't feel silent either.
CORRECTNESS FIXES
=================
- MakerWorld imports were persisting URL-encoded filenames verbatim
("stormtrooper-helmet%20h2d.3mf"). Backend now urllib.parse.unquote
s the manifest-supplied name and the URL path-tail fallback before
passing to save_3mf_bytes_to_library; frontend defensively
decodeURIComponent s in the slice toast / analysis spinner so
already-imported rows display cleanly without a backfill migration.
- The fallback path's slice_without_profiles call now forwards the
same request_id + on_progress as the primary slice_with_profiles
call so the toast keeps updating across the segfault -> embedded-
settings retry boundary instead of going blank.
ORCASLICER WARNING
==================
Verified two upstream OrcaSlicer CLI bugs reproduce on the latest
nightly (2.4.0-dev, 2026-04-28) with the help of an isolated AppImage
extract and a minimal sentinel-value-injected cube fixture:
- OrcaSlicer/OrcaSlicer#12426 -- SIGSEGV in
update_values_to_printer_extruders_for_multiple_filaments on
painted multi-extruder 3MFs (commented on the existing thread,
not a new issue)
- OrcaSlicer/OrcaSlicer#13386 -- CLI strict-validates parameter
values BambuStudio writes by default (solid_infill_filament: 0,
tree_support_wall_count: -1, prime_tower_brim_width: -1) and
rejects with exit 238, even though Orca's own GUI tolerates
them (filed by us alongside this change)
Settings -> Workflow -> Slicer card renders an amber inline warning
under the preferred-slicer dropdown when orcaslicer is selected,
linking both upstream issues and recommending BambuStudio until the
fixes land. Option stays pickable -- users who only slice STLs aren't
affected by either bug.

fix(slicer): wrong-printer slicing + sliced-archive filament list + per-instance MakerWorld compat
Five stacked slice-pipeline bugs that each made the modal's profile picker
theatrical for 3MF inputs:
(1) `_strip_3mf_embedded_settings` removed `model_settings.config` /
`slice_info.config` / `cut_information.xml` along with
`project_settings.config`. The CLI silently exited after
"Initializing StaticPrintConfigs" — exit 0, no result.json — and
Bambuddy masked the failure by re-running with embedded settings
and the source's bound printer. Strip removed from the dispatch
path entirely.
(2) Standard-tier preset stubs lacked the `type` field, so the CLI
rejected `--load-settings` with rc=-5 ("input preset file is
invalid") and the same masking fallback fired. Added
`_SLOT_TO_PROFILE_TYPE` so each stub carries the right
machine/process/filament discriminator.
(3) Sliced-archive cards listed every project-wide AMS slot (16+
swatches for a 2-color print). `slice_and_persist_as_archive` now
reads `filament_type` / `filament_color` from the sliced output's
`slice_info.config` (which `ThreeMFParser` already gates on
`used_g > 0`) instead of inheriting from the source archive.
(4) SliceModal had no warning when the picked printer profile didn't
match the source 3MF — the CLI rejects cross-printer slices
(rc=-16) and fell back to embedded settings, producing wrong-printer
g-code that errored at print dispatch. Plates response now exposes
`source_printer_model`; the modal compares against the picked
profile name and disables Slice + shows an inline warning on
mismatch.
(5) MakerWorld URL-paste resolver listed plate instances without
showing which printer each was sliced for (`/instances/hits`
omits compatibility info that lives on `design.instances[]
.extention.modelInfo`). The resolve route now joins both payloads
by instance ID and forwards `compatibility` + `otherCompatibility`
onto each hit; the MakerWorld page renders "Sliced for {primary}"
+ "Also marked compatible: ..." per row.
Tests: 6 unit tests for `extract_source_printer_model_from_3mf`, 1 for
filtered filament metadata via ThreeMFParser, 2 for makerworld resolve
compat-merge (happy path + missing modelInfo), 3 frontend SliceModal
tests for the printer-mismatch warning + Slice-disabled gate. New i18n
keys `slice.printerMismatch`, `makerworld.slicedFor`,
`makerworld.alsoCompatible` across all 8 locales.

feat(slicer): multi-color slicing + per-plate filament discovery
The slice modal previously rendered exactly one filament dropdown and
silently truncated multi-color 3MFs to a single profile, producing wrong
colours on every multi-filament print. End-to-end fix across sidecar,
backend, and frontend.
Sidecar (orca-slicer-api / bambuddy/profile-resolver, separate commit):
- /slice accepts up to 16 repeated filamentProfile parts; slicing
service materializes each and joins paths with `;` for
--load-filaments.
- /profiles/bundled emits filament_type and filament_colour per leaf
so the bundled tier carries metadata into the modal.
Bambuddy backend:
- SliceRequest gains filament_presets: list[PresetRef]. Validator
accepts three shapes (multi-color array, source-aware singular,
legacy bare-int id) and lands them all on a populated array before
the route handler runs — fully backwards-compatible.
- SlicerApiService.slice_with_profiles takes filament_profile_jsons:
list[str] and sends one filamentProfile multipart part per profile
(in submission order) so the sidecar receives N profiles cleanly.
- New service slice_preview runs the sidecar's slice_without_profiles
against an unsliced project file's embedded settings, parses the
result's slice_info.config, and returns the canonical per-plate
filament list. Cached by (kind, source_id, plate_id, content_hash)
with LRU eviction at 256 entries, per-key asyncio.Lock prevents
thundering-herd; transient sidecar failures are NOT cached so they
retry naturally; parse failures ARE cached (deterministic property
of the input, no point re-running).
- /filament-requirements endpoint chain: slice_info.config (existing,
sliced files) → preview-slice (new, unsliced project files) →
project_settings.config + painted-face heuristic with 5% noise
threshold (sidecar-down fallback).
- threemf_tools gains extract_project_filaments_from_3mf and
extract_plate_extruder_set_from_3mf — the latter unions object
top-level extruder, per-part overrides, and painted-face quadtree
leaves (1-E nibbles in paint_color attrs of <triangle> elements
inside per-object .model files).
- Cloud preset listing no longer fetches per-preset detail (Bambu's
rate limit at ~10/sec returns 429 on every request for users with
50+ presets). Unified-listing dedup pass instead backfills metadata
cross-tier so a cloud entry that wins dedup over a same-named local
entry inherits the local's filament_type / filament_colour.
Frontend:
- SliceModal multi-step: plate-picker first when the source is a
multi-plate 3MF, then preset dropdowns. One filament dropdown per
AMS slot the plate actually uses, each pre-picked by metadata
match against user's local + standard presets via existing
colorsAreSimilar / normalizeColorForCompare utils.
- SliceModal-only tier priority is now local → cloud → standard
(was cloud → local → standard). Other consumers of /slicer/presets
keep the existing cloud-first order.
- Submits filament_presets array; backfills the legacy singular
filament_preset from the array's first entry for stale-tab
compatibility.
- i18n keys added across all 8 locales: slice.filamentSlot,
slice.tier.{local,cloud,standard}, slice.cloud.{notAuthenticated,
expired,unreachable}, slice.noPresetsForSlot,
slice.allPresetsRequired (en + de fully translated; six others
seeded with English copies pending native translation, matching
the project's existing flow).
Permissions: no new endpoint paths added. Preview-slice runs inside
/filament-requirements (LIBRARY_READ / ARCHIVES_READ) and multi-filament
dispatch runs inside POST /slice (LIBRARY_UPLOAD). No auth surface
widened.
Tests: 6 SliceRequest schema tests for multi-filament + legacy-new
precedence; 9 unit tests for slice_preview cache behaviour (LRU
eviction with lock cleanup, content-hash invalidation, concurrent
thundering-herd guard, no-cache-poison on transient sidecar failure);
15 unit tests for the two new threemf_tools helpers (5 + 10 cases
including the 60/40 painted-threshold regression pin); a multi-filament
wire-format test pinning the multipart part count + order; 22 frontend
SliceModal tests covering plate picker, multi-color render,
metadata-aware pre-pick, manual override, and the new tier order.

fix(#1150): skip MQTT reconnect on watchdog timeout when project_file landed
Background: P1P firmware can take ~135 s after a project_file MQTT publish
to actually start parsing the uploaded .3mf — gcode_state stays IDLE and
subtask_id doesn't advance until parse completes. The dispatch watchdogs
treated the missed transition as a #887/#936 half-broken session and called
force_reconnect_stale_session, which interrupts the printer's in-progress
parse and triggers 0500_4003 ("can't parse print file") on the printer side.
Both #1150 (slow parse) and #887/#936 (zombie session) look identical from
state and subtask_id alone — both have stale state and stale subtask_id with
fresh telemetry. The distinguishing signal is the printer's gcode_file
field: it updates in push_status when the project_file command actually
lands on the printer, but stays unchanged when the publish was silently
swallowed.
Both watchdogs (_verify_print_response in background_dispatch and
_watchdog_print_start in print_scheduler) now capture pre_gcode_file from
printer_manager.get_status() before sending the publish, then on timeout
compare it against the last good status seen during the poll loop. If the
file changed, the command landed → log a #1150 warning, skip the forced
reconnect to avoid 0500_4003 mid-parse. If unchanged, fall through to the
original force_reconnect_stale_session call so the half-broken-session
recovery is preserved exactly.
Caveat documented in code: in a retry-same-file slow-parse scenario the
gcode_file looks identical pre/post-publish, so the watchdog falls through
to the reconnect path and the user still hits 0500_4003 on that retry.
Accepted to avoid breaking the half-broken-session recovery, which is the
more impactful regression of the two.
The new pre_gcode_file kwarg has a default of None on both watchdog
functions, so any caller that doesn't pass it keeps the original
reconnect-on-timeout behavior verbatim.
4 new unit tests cover both watchdogs: skip on gcode_file change (#1150
fix), reconnect when unchanged (#936 protection preserved), skip when
pre=None and current is non-None (printer just connected), reconnect when
pre_gcode_file arg is omitted (backward-compat). All 439 existing
dispatch / scheduler / mqtt tests pass unchanged.

feat(slicer): unified Cloud/local/standard presets + harden 3MF profile path
UNIFIED PRESET LISTING (the main feature)
The initial slicer integration only saw DB-backed local imports — users
without imported profiles got an empty Slice modal even when their
Bambu Cloud account or the slicer sidecar carried perfectly usable
presets. The Slice modal now pulls from three tiers in priority order:
- cloud: user's own Bambu Cloud presets, fetched live.
- local: DB-backed imports.
- standard: slicer-bundled stock profiles via the sidecar's new
GET /profiles/bundled endpoint.
Listing endpoint: GET /api/v1/slicer/presets
- Name-based dedup, cloud > local > standard, within-tier order
preserved exactly. A preset that exists in multiple tiers only
renders in the highest-priority one.
- cloud_status (ok / not_authenticated / expired / unreachable)
drives a precise modal banner instead of an unexplained empty
list.
- Cloud branch: per-user cache, 5 min TTL, key
(user_id, sha256(token)[:16]) so logout/login or token rotation
auto-invalidates without callback wiring from the cloud-auth
routes.
- Bundled branch: global cache, 1 h TTL.
- Bundled URL respects preferred_slicer (bambu_studio vs orcaslicer)
so BambuStudio installs see the bambu sidecar's bundled list, not
OrcaSlicer's.
Slicing endpoint: POST /library/files/{id}/slice + /archives/{id}/slice
- Body now accepts source-aware {source, id} triplets per slot:
printer_preset: PresetRef
process_preset: PresetRef
filament_preset: PresetRef
- Legacy *_preset_id integer fields kept for backwards-compat. The
schema validator normalises bare ints into
PresetRef(source='local', id=str(int)) so the route handler only
deals with one shape.
New preset_resolver service fetches the JSON content per source:
- cloud: BambuCloudService.get_setting_detail(id), unwraps the
`setting` envelope (falls back to top-level for minor
shape variants).
- local: DB read with preset_type slot validation (existing path,
factored into the new helper).
- standard: minimal {name, inherits, from: "system"} stub — the
sidecar's profile-resolver flattens it against
BUNDLED_PROFILES_PATH/<category>/<name>.json with no
preset-content round-trip from Bambuddy.
PERMISSIONS
- Listing route gate: LIBRARY_UPLOAD (matches the slice action — any
user who can slice can populate the dropdowns).
- Cloud branch in BOTH the listing helper and the resolver checks
CLOUD_AUTH independently — a user with LIBRARY_UPLOAD but not
CLOUD_AUTH doesn't see the cloud tier (returns 403 if they try
to slice with a cloud preset) even if a leftover User.cloud_token
survived a permission revocation. Cloud listing path
short-circuits the token lookup entirely on the gate-fail branch.
FRONTEND — SliceModal
- Calls api.getSlicerPresets() instead of api.getLocalPresets().
- Dropdowns render <optgroup> per tier with localised section
labels (Cloud / Imported / Standard).
- Default selection follows cloud > local > standard priority on
first load (auto-pick fires once when the data arrives, manual
choices stick after that).
- Cloud-status banner renders three variants
(sign-in / expired / unreachable) only when status != 'ok'.
- Slice button submits source-aware refs; legacy integer payload
is preserved server-side for older clients.
3MF PROFILE-PATH HARDENING (shipped together because they touch the
same code paths)
(1) Strip widened. _strip_3mf_embedded_settings only removed
Metadata/project_settings.config. Real-world Bambu Studio /
OrcaSlicer 3MFs also carry model_settings.config, slice_info.config,
and cut_information.xml — any single leftover trips the CLI's
input validation and the slice falls back to embedded settings,
making the SliceModal's profile picker theatrical for 3MF inputs.
Now removes all four configs via a centralised
_STRIPPABLE_3MF_CONFIGS frozenset with per-file rationale;
geometry (3D/3dmodel.model), thumbnails, multi-part data
preserved.
(2) Sidecar 5xx error capture. slicer_api.py was reading only
`message` from sidecar 5xx responses and dropping `details`, so
every CLI failure surfaced as the unhelpful generic
"Failed to slice the model". New _format_sidecar_error helper
combines both fields, falls back to plain-text body for
non-JSON 5xx (nginx 502s, gateway timeouts), replaces the four
duplicated extraction blocks. Pairs with the orca-slicer-api
fork's bambuddy/profile-resolver branch which now emits
`details` on AppError responses (d9c6121) and captures CLI
stderr in the failure path (fb928c8).
CARE TAKEN — additive on existing surfaces
- main.py: +1 import, +1 router register
- slicer_api.py: +list_bundled_profiles, +_format_sidecar_error
(dedupes the 4 message-extraction blocks);
no existing method behaviour changed
- library.py: resolver swap inside _run_slicer_with_fallback,
user_id threaded through two callers,
strip widened
- schemas/slicer.py: PresetRef added, *_preset fields added,
legacy *_preset_id kept; validator normalises
- 4 new files: schema, route, resolver, tests
- No existing route URL changed, no existing field removed, no
behaviour change for clients still sending bare integer ids.
TESTS
- 17 unit tests for the listing endpoint helpers
- 11 unit tests for the source-aware resolver
- 6 schema tests for SliceRequest legacy + new shapes
- 3 unit tests for the new sidecar error-detail capture
- Strip integration test extended to assert all 4 configs go and
geometry stays
- 12 frontend tests for SliceModal covering tier-priority
auto-selection, <optgroup> grouping, fallback paths, source-aware
payload on submit, manual override across tiers, archive vs
library routing, error display, all three banner variants
Verified: 3394 backend + 1531 frontend tests pass, ruff clean,
frontend production build clean.
Pairs with three already-pushed commits on the orca-slicer-api fork's
bambuddy/profile-resolver branch:
- 5fd6bc6 feat(profiles): add GET /profiles/bundled
- d9c6121 fix(error): include causeMessage in JSON response as `details`
- fb928c8 fix(slicing): include CLI stdout/stderr in failure causeMessage

● feat(slicer): server-side slicing via OrcaSlicer / Bambu Studio sidecar
Adds an optional slicer-api/ Compose stack and wires Bambuddy's File
Manager, Archives, and MakerWorld pages to a new server-side Slice flow.
Slicing runs as an in-memory background job (POST returns 202 + job_id,
polled via GET /api/v1/slice-jobs/{id}) so a multi-minute slice no
longer pins the modal; result lands as a new .gcode.3mf in the same
folder (or new archive for archive sources) with the embedded
thumbnail extracted.
Backend
- New services: slice_dispatch (in-memory dispatcher, 30min retention
sweep) and slicer_api (HTTP bridge with 4xx/5xx/connection error
split that drives the 3MF embedded-settings fallback retry path).
- New schemas: SliceRequest, SliceResponse, SliceArchiveResponse,
SliceJobEnqueueResponse.
- New routes: POST /library/files/{id}/slice,
POST /archives/{id}/slice, GET /api/v1/slice-jobs/{id} (gated on
LIBRARY_READ since job IDs are sequential and the body leaks source
filenames and result IDs).
- AppSettings + env defaults: use_slicer_api, orcaslicer_api_url,
bambu_studio_api_url. DB-stored values override env defaults.
Frontend
- New SliceModal handles preset gating; enqueues then closes
immediately.
- New SliceJobTrackerProvider polls active jobs at app level, surfaces
a single toast per job (queued -> running -> completed / failed)
and invalidates library/archives queries on terminal status.
- Settings -> Workflow -> Slicer card: preferred slicer dropdown,
Use Slicer API toggle, contextual sidecar URL field.
- File Manager / Archives / MakerWorld get a Slice button gated on
the Use Slicer API setting.
- gcode-viewer adapter learns ?library_file=<id> so sliced library
files preview inline.
i18n
- New slice.* and settings.{useSlicerApi,slicerCard,orcaslicerApiUrl,
bambuStudioApiUrl,slicerApiUrlDescription,useSlicerApiDescription}
+ fileManager.noPermissionSlice keys across all 8 locales (en, de,
fr, it, ja, pt-BR, zh-CN, zh-TW). English fully translated, German
fully translated, the other six seeded with English fallbacks
pending native translation.
Tests
- 10 backend integration tests in test_library_slice_api.py covering
validation (404/400), happy-path enqueue, sidecar-down, 3MF
embedded-settings fallback, STL no-fallback, and preset-error ->
failed job paths.
- New unit tests in test_slicer_api.py for the HTTP bridge.
- 5 new SliceModal frontend tests covering preset gating, library +
archive enqueue paths, error surface, and preset-load failure.
- Existing SettingsPage tests adjusted: slicer dropdown asserts now
switch to the Workflow tab first; added a beforeEach URL reset so
one test's tab click doesn't bleed into sibling tests.
Sidecar
- New slicer-api/ folder is self-contained and optional. Two services
(orca-slicer-api on 3003, bambu-studio-api on 3001 behind --profile
bambu) build via Docker git-build-context from
maziggy/orca-slicer-api@bambuddy/profile-resolver. The fork patches
the OrcaSlicer CLI's profile compatibility quirks (inherits-chain
resolver, from:User -> system rewrite, '# ' clone-prefix strip,
sentinel-value strip) empirically required to slice real GUI
exports without segfaulting the CLI.
Docs
- CHANGELOG entry under [0.2.4b1] - Unreleased Added.
- README File Manager bullet for the new server-side Slice button.
- bambuddy-website features.html: new card under "Configurable Slicer".
- bambuddy-wiki: new page features/slicer-api.md + nav entry +
features index card.
Notes
- Opt-in: with Use Slicer API off, the existing "open in desktop
slicer via URI" flow is the default and unchanged.
- 3MF inputs that segfault the CLI on --load-settings transparently
retry with embedded settings; the resulting job carries
used_embedded_settings: true.
- Sliced files always export as .gcode.3mf so File Manager picks up
the embedded thumbnail; file_type is set to "gcode" (blue badge).

fix(mqtt): #1136 reprint fails with 0500_4003 SD R/W after stuck dispatch
Reprinting from archives sometimes failed immediately with a MicroSD R/W
exception, with the printer's MQTT push referencing a 3MF from a
different unrelated archive. Once it started, every subsequent reprint
hit the same error until the container was restarted.
Root cause from @smandon's support package: paho-mqtt's client-side QoS
1 queue. When the printer's command channel goes half-broken (telemetry
flowing, publishes silently dropped — same #887/#936 pattern),
background_dispatch.py:993 hits its 15s deadline and calls
force_reconnect_stale_session(). That function was force-closing the
underlying socket so paho's auto-reconnect would kick in, but the same
mqtt.Client instance, same client_id, and same in-process QoS 1 queue
stayed alive across the reconnect. Any unacked publish from the broken
session — typically the just-sent project_file for the new archive —
got replayed verbatim on the new connection. The queue accumulates
across multiple stuck dispatches in one Python process, so by the
second or third stuck reprint there were several stale
project_file/resume/stop/clean_print_error commands queued together;
the printer latched onto whichever stale path it processed last,
couldn't find the file on its SD card, and emitted 0500_4003. Container
restart was the only thing that wiped paho's in-process queue.
Replaced socket-close with a context-aware reconnect via a new
_reset_client_for_reconnect() router:
Async-context callers (dispatch deadline, FastAPI handlers via
check_staleness) → hard-reset: client.disconnect() (broker drops
session, clean_session=True), client.loop_stop() (kills paho's
network thread and its queue), null _client, fresh connect() with
incremented client_id. New connection is genuinely empty, no replay.
Paho-network-thread callers (dev-mode probe + ams_filament_setting
zombie detection inside _update_state) → socket-close fallback.
loop_stop() from inside the network thread would self-join and
deadlock, so the safe pattern there is "close the socket and let
paho's loop detect it and auto-reconnect on the same client".
Routing decision uses asyncio.get_running_loop() — paho's callback
thread has no loop, every legitimate hard-reset caller does.
7 regression tests:
- TestForceReconnectRouting (3): sync-context → socket-close fallback,
async-context → hard-reset with disconnect()+loop_stop()+null,
state-disconnected broadcast fires once on either path
- TestHardResetClientDirect (3): helper directly — old client gets
disconnect()+loop_stop(), _client cleared, failing disconnect()
doesn't propagate so background_dispatch's await chain can't break
- TestZombieSessionDetection / TestDeveloperModeProbeTimeout (updated):
paho-thread context still goes through socket-close, preserving the
legacy contract for those paths

fix: cancel = layer shift, stuck "1 problem", and dropped child-logger logs
Three bugs that surfaced together while debugging an H2D cancel:
1. Cancelling a print stamped failure_reason="Layer shift" in archives
AND left the printer card stuck on "1 problem" forever. Four causes:
(a) POST /printers/{id}/print/stop never set the user-stopped flag, so
on_print_complete couldn't override "failed" -> "cancelled".
(b) HMS-derived failure_reason heuristic mapped any module-0x0C HMS to
"Layer shift". Module 0x0C is "Motion Controller" broadly (includes
cameras, markers, AND the cancel-sequence echo 0C00_001B). Real
layer-shift codes live in module 0x03. Same false-positive class
existed for "Filament runout" (any 0x07) and "Clogged nozzle" (any
0x05). Replaced with a 23-code curated short-code map; unknowns
leave failure_reason=None.
(c) Cancel-echo HMS codes (0300_400C "The task was canceled.",
0500_400E "Printing was cancelled.") were polluting state.hms_errors
via both the hms[] and print_error parse paths. Filter them at
parse time so the frontend never sees them.
(d) Frontend bucketed gcode_state="FAILED" as a problem unconditionally.
Real failures attach an HMS error; user-cancels don't — so FAILED-
without-HMS now buckets as "finished" and only escalates to "error"
when there's an active known HMS.
2. logs/bambuddy.log was silently dropping records from named child
loggers. TraceIDFilter was attached to root_logger, but Python's
logging only invokes a Logger's filters on records originating at that
logger — propagated child-logger records skipped it, formatter raised
KeyError, handler.handleError dropped the record. Moved the filter
from root_logger.addFilter() to handler.addFilter() on each handler,
matching the filter's own docstring guidance.
derive_failure_reason() extracted as a pure function for testability.
status="cancelled" now symmetrically yields "User cancelled" alongside
"aborted".
20 regression tests across:
- backend/tests/unit/test_failure_reason_derivation.py (11)
- backend/tests/unit/services/test_bambu_mqtt.py::TestHMSUserActionFiltering (4)
- backend/tests/unit/test_trace.py::TestFilterMustBeAttachedToHandlerNotLogger (1)
- frontend/src/__tests__/pages/PrintersPageBucketing.test.ts (5; includes
the H2D-cancel-echo "FAILED + only unknown HMS" case)

fix(#1128): broadcast printer_status when awaiting_plate_clear flips
awaiting_plate_clear is a Bambuddy-side flag, not a printer-side one,

fix(camera): catch RuntimeError in TLS proxy forwarders for uvloop
The bidirectional forwarders inside create_tls_proxy._handle catch
(ConnectionError, OSError, asyncio.CancelledError) on writes, but
uvloop's UVStream.write raises a plain RuntimeError from
UVHandle._ensure_alive when the underlying handle is already closed.
asyncio's default selector loop reports the same situation as
ConnectionResetError, so the bug only surfaced on uvloop — and only at
the moment ffmpeg (or a snapshot-capture subprocess) dropped its socket
while the proxy was mid-flush.
The RuntimeError slipped past the except tuple, escaped the forwarder
coroutine, and asyncio's client_connected_cb task-exception handler
logged a noisy multi-line traceback ending in:
RuntimeError: unable to perform operation on
<TCPTransport closed=True ...>; the handler is closed
Adds RuntimeError to the except tuple in both _fwd_to_server and
_fwd_to_client (the latter is the actual frame from the bug report —
server→client is where buffered TLS chunks land after the client has
gone). The forwarders are intentionally fire-and-forget on tear-down;
the existing dst.close() in the finally block already handles cleanup.
No functional regression possible — the connection is already dead by
the time the exception fires; this only changes whether asyncio logs an
"Unhandled exception" trace for it.
2 new regression contract tests in test_camera_tls_proxy.py use
inspect.getsource to assert both forwarder closures' except clauses
include RuntimeError. Source-level rather than a runtime test because
the forwarders are nested closures inside _handle and extracting them
just for testability would require a pure-cosmetic refactor.

fix(#1134): propagate background-dispatch watchdog timeout as job failure
Follow-up to #1042. The post-dispatch watchdog _verify_print_response was fire-and-forget — it correctly detected when the printer never transitioned (HMS error pending, half-broken MQTT session, plate-clear gate, SD card fault) and force-reconnected the MQTT session, but the dispatch job had already been marked successful on the optimistic MQTT-publish-acknowledged path. The UI carried on showing "Print started successfully" while the printer sat idle. The watchdog now returns bool and is awaited inline by both call sites in _run_reprint_archive and _run_print_library_file. On False the call sites raise a RuntimeError carrying a user-actionable message ("Printer did not acknowledge print command — state still {pre_state}. Check the printer for a pending error...") which routes through the existing _run_active_job → _mark_job_finished(failed=True) → background_dispatch WS broadcast path. Library-file flow rolls back the freshly-created archive on timeout so no phantom row is left behind for a print that never started. The watchdog now also accepts subtask_id advancing past pre_subtask_id as a definitive "command landed" signal — same as the queue-side watchdog at print_scheduler.py:1992 — so slow H2D FINISH→PREPARE transitions (~50 s observed) don't false-fail when the printer has clearly accepted the project_file but is still in FINISH. Default timeout raised from 15 s to 90 s to match the queue-side watchdog and give the same headroom on both dispatch paths. Brief mid-window MQTT disconnects keep polling instead of immediately failing — matches what the queue watchdog already does and avoids false-failing on transient telemetry gaps. 11 new tests in test_background_dispatch_watchdog.py: state-change pickup, subtask_id-change pickup with state still FINISH, neither-changed timeout plus force_reconnect_stale_session call, pre_subtask_id=None backwards- compat, post-dispatch subtask_id=None not counting as a change, brief disconnect not short-circuiting the window, persistent disconnect for the full window returning False, default-timeout=90s contract, _run_reprint_archive raises RuntimeError with the captured pre-state args on watchdog False, _run_reprint_archive happy path doesn't rollback, _run_active_job marks the job failed with the message when _process_job raises RuntimeError. |

fix(#918): RFID auto-match handles Quick-Add and rejects non-Bambu brands
`find_matching_untagged_spool` is supposed to attach an incoming Bambu
RFID UUID to a pre-existing manually-logged spool of the same
material/color so users who log inventory before scanning don't end up
with duplicate rows. Two bugs meant it almost never worked for the
actual reporting workflow:
1. Subtype filter was strict. AMS reports `tray_sub_brands="PLA Basic"`
→ matcher required `Spool.subtype = 'Basic'` exactly. The form's
Quick-Add mode only requires `material`, so bulk-logged rows have
`subtype=NULL` and were always excluded → duplicate on first AMS
read.
2. Brand wasn't filtered. The docstring claimed brand was matched but
the WHERE clause didn't include it, so a same-color Polymaker (or
any non-Bambu) untagged row could acquire a Bambu UUID — silent
data corruption.
Fix in the same query: subtype prefers exact match but accepts NULL as
fallback (CASE in ORDER BY ensures exact wins when both exist); brand
restricted to NULL or LOWER(brand) LIKE '%bambu%' (covers 'Bambu',
'Bambu Lab', 'BambuLab', 'bambu lab' — the spellings users actually
type).
6 regression tests added in test_spool_tag_matcher.py.

feat(notifications): per-event ntfy priority headers (#990)
ntfy supports a Priority header (1=min, 2=low, 3=default, 4=high, 5=urgent) that controls escalation on the receiving device, but every event was being sent at the server default — so a "50% complete" ping looked identical to "print failed" or "printer offline". Add a per-event priority dropdown section in the Add/Edit Notification modal (visible only for ntfy, listing only enabled events); the backend reads config.event_priorities and emits the matching Priority header on POST and PUT (image-attachment) paths. Unmapped events fall through to the ntfy server default. Out-of-range and non-numeric values are dropped, not clamped, so a misconfigured value never silently sends at the wrong urgency. Test sends omit the header by design so the test path can't accidentally page someone at urgent priority. Backward compatible: existing providers without event_priorities behave exactly as before. NtfyConfig.event_priorities is optional; the route stores config as a JSON blob so no migration is needed. i18n: full translations across all 8 locales (en/de/fr/it/ja/pt-BR/zh-CN/ zh-TW). README, CHANGELOG, and the wiki notifications page updated. Tests: 6 backend (Priority set on mapped, omitted on unmapped/missing/ no-priorities, ignored for bad values, propagated through attachment path), 6 frontend (section visible only for ntfy, lists only enabled events, save round-trip, edit pre-fill, toggle drops row, non-ntfy never writes the key). |

feat(#1108): long-lived camera-stream tokens + fix(#1089) audit-pass tweaks
#1108 — Long-lived camera-stream tokens for HA / Frigate / kiosks. Camera-only V1, hard 365-day cap (no infinite tokens), pbkdf2 hashed at rest, plaintext shown to user exactly once on creation. New "Camera API Tokens" panel under Settings → API Keys with self-service create/revoke, styled confirm modal, admin "All users" view for leak triage. Auth path: /camera/stream tries the existing 60-min ephemeral table first, falls through to the long-lived path. Indexed lookup_prefix keeps verify O(1) per token. Permission audit: gated the existing API-keys-CRUD + Webhook docs + API Browser content behind api_keys:read so non-admins with camera:view land on the API Keys tab and see only the Camera Tokens panel they actually have permission to use. Grid layout collapses to single column for non-admins. Tests: 29 new backend (15 service + 14 integration covering create/list/ revoke ownership rules, the auth fall-through, scope enforcement, prefix collisions) + 6 new frontend tests for the section UI including the new modal flow. All 77 backend tests + 21 frontend camera tests pass. Ruff clean (lint + format). Docs: README updated with fan-out + long-lived-token bullets. Wiki gets a new "Long-Lived Camera Tokens" section under features/camera.md (HA YAML example, security model, permission requirements, revoke flow). Website features.html gets the bullet under Camera Streaming. Also includes #1089 follow-up tweaks already merged in this branch: _stream_start_times.setdefault for accurate stream_uptime, subscribe() RuntimeError retry to close the grace-vs-subscribe race, atomic unsubscribe count via the iter_subscriber on_unsubscribe callback. |

fix(#1089): camera stream fan-out broadcaster
Most Bambu Lab printers only allow one concurrent camera connection, but
GET /printers/{id}/camera/stream opened a fresh upstream per viewer.
Two browser tabs → second viewer fails or kicks the first off.
New MjpegBroadcaster (services/camera_fanout.py) owns one upstream per
printer and fans MJPEG chunks out to N subscribers. 5 s grace window
absorbs tab refreshes without reconnecting. Bounded subscriber queues
drop frames for slow viewers rather than blocking the broadcaster.
Audit-pass fixes:
- _stream_start_times set with setdefault() so stream_uptime reflects
the shared upstream's age, not the most-recent viewer's
- subscribe() retried once on RuntimeError to close a tiny grace race
- unsubscribe() returns post-removal count atomically so the detach log
no longer races with concurrent leavers
Permission gates unchanged; broadcaster has no FastAPI surface.
Tests: 13 broadcaster unit tests + 2 integration tests on /camera/stop.
External-camera path untouched.

● fix(#1111): advance queue item when print fails before reaching RUNNING
When a file sliced for the wrong nozzle size is dispatched, the printer goes IDLE -> PREPARE -> FAILED without ever entering RUNNING. Completion detection required prev=RUNNING or _was_running=True, so on_print_complete never fired and the queue item stayed at "printing" forever -- blocking every subsequent pending item for that printer (check_queue seeds busy_printers from any row in 'printing'). Fire completion on FAILED from PREPARE or SLICING too. Restricted to those two pre-print states so a stale FAILED on first connection (prev=None) still can't accidentally advance an unrelated queue item. Also populate PrintQueueItem.error_message from the current HMS error list via the existing hms_errors.py lookup, so users see e.g. "[0500_4038] The nozzle diameter in sliced file is not consistent with the current nozzle setting" instead of a blank failure reason. |

fix(virtual-printer): cert-renewal restart regression + clipboard leak
1. `_cancel_restart_task` self-await guard (manager.py:389-413).
stop_server() / stop_proxy() are called from inside
_restart_for_cert_renewal, which runs AS _cert_restart_task.
Cancelling+awaiting self flagged a CancelledError on the next
`await` in stop_server, tearing down old listeners but never
letting start_server run — the VP sat on the expired cert
until the process was manually restarted, silently defeating
auto-renewal. Skip when `task is asyncio.current_task()` and
just clear the reference.
2. Clipboard fallback textarea leak (VirtualPrinterCard.tsx:66-81).
The HTTP fallback created a hidden textarea, called
select() + execCommand('copy'), then removed the textarea.
If select() or execCommand threw, removal never ran and the
textarea leaked into the DOM. Move the removal into `finally`
so it happens regardless of the inner block's outcome.
Regression tests in test_tailscale.py::TestCancelRestartTaskSelfAwait
cover both the self-cancel path (must NOT cancel self) and the
outside-cancel path (must still cancel and await).

feat(docker): Tailscale integration support via host socket mount
Add the Tailscale CLI to the production image and document how to
enable Let's Encrypt cert provisioning for virtual printers from a
Docker-deployed Bambuddy.
- Dockerfile installs `tailscale` from the official Debian repo. Only
the CLI is used at runtime; tailscaled itself stays on the host.
The binary is harmless if the socket isn't mounted — the code logs
an actionable hint and falls back to self-signed certs.
- docker-compose.yml adds a commented-out volume mount for
/var/run/tailscale/tailscaled.sock with inline setup instructions.
- tailscale.py's docker-socket hint now also fires when the binary is
present but the daemon socket is unreachable (i.e. the new Docker
pattern), not just when the binary is missing, so users get the
actionable "mount the socket" message instead of opaque CLI stderr.
Enabling the integration on a Docker host:
1. `curl -fsSL https://tailscale.com/install.sh | sh` on host
2. `sudo tailscale up`
3. `sudo tailscale set --operator=<user>` for the container PUID
4. Uncomment the tailscaled.sock mount in docker-compose.yml
5. `docker compose up -d --force-recreate`
6. Flip the Tailscale toggle on the VP card

fix(#1105): recognise new H2C serial prefix "31B8B" for dual-nozzle detection
Bambu started shipping H2C units with a new serial prefix (`31B8B…`
observed on a January 2026 unit) instead of the legacy `094…` shared by
the H2D/H2C/H2S family. Two serial-prefix-driven paths — the K-profile
edit branch in `kprofiles.py` and the delete-K-profile MQTT command in
`bambu_mqtt.py::delete_kprofile` — were silently routing the new units
through the single-nozzle format.
Match on 5 chars (`31B8B`): covers the 3-char model code plus the two
revision bytes, leaving the revision-letter slot free to iterate. This
mirrors the X2D precedent of using a longer-than-3-char prefix when a
single data point can't confirm family reuse.
Runtime dual-nozzle detection via `device.extruder.info` count and
model-string branches (`self.model in ("H2C", "H2D", …)`) are already
prefix-agnostic — no change needed there.
- backend/app/api/routes/kprofiles.py: add "31B8B" to is_h2d tuple
- backend/app/services/bambu_mqtt.py: same in delete_kprofile
- backend/tests/unit/services/test_bambu_mqtt.py: regression test

● feat(#1008): honour reprint dates in archive purge + clarify purge UX
Fix a silent correctness bug: archive purge used `created_at` which is
pinned to the first print, so reprinting a two-year-old archive yesterday
would still make it eligible for a 365-day purge. The preview and purge
queries now age each archive by `COALESCE(completed_at, started_at,
created_at)` — reprints refresh the clock.
Also flesh out both purge modals (File Manager + Archives) with an
explicit "What happens when you click Purge" effects list so users see
upfront that library files go to Trash (reversible) while archives are
hard-deleted (irreversible), plus what disk artefacts get removed.
Backend:
- services/archive_purge.py: `_last_activity_expr()` helper used by
preview, purge, and sample query
- tests/integration/test_archive_purge_api.py: new test covering the
reprinted-archive case
Frontend:
- PurgeOldFilesModal / PurgeArchivesModal: new effects bullet list
- i18n: reprint-aware ageLabel/description/warning and effects bullets
across all 8 locales (en/de fully translated, rest English fallback)
Docs:
- wiki/features/archiving.md: "How old is measured" note + effects list
- wiki/features/file-manager.md: "What happens when you click Purge"
section + explicit age-rule breakdown
- CHANGELOG: archive auto-purge entry rewritten to mention reprint
semantics, `archives:purge` permission backfill, and updated test count

feat(#1008): archive auto-purge + dedicated archives:purge permission
Adds an archive counterpart to the library trash sweeper shipped in the
previous commit. Unlike the library flow, archives are hard-deleted —
print history is a decaying timeline, so there is no trash intermediate;
download or favourite anything you want to keep first.
Backend
- New ArchivePurgeService (backend/app/services/archive_purge.py) with
its own 15-minute scheduler loop and a 24h throttle on actual purge
runs. Delegates every delete to the existing safety-checked
ArchiveService.delete_archive so the 3MF, thumbnail, timelapse, source
3MF, F3D, and photo folder all get cleaned up together with the DB
row. Per-row session via async_session() avoids commit-per-row churn
on any caller-passed session.
- New /archives/purge/{preview,settings} + POST /archives/purge routes
gated on a dedicated archives:purge permission (not archives:delete_all)
so admins can delegate bulk-delete to a role without granting
per-archive delete on other users' rows.
- seed_default_groups() now backfills both library:purge and
archives:purge on the Administrators group for upgraded installs —
the original library:purge was added after Administrators was first
seeded so the "create if not exists" path skipped existing DBs and
left admins without the permission.
- 8 new integration tests (defaults, settings roundtrip, bound
validation, preview, manual purge, auto-purge enabled path, 24h
throttle, disabled skip).
Frontend
- Settings → Archives card gains an auto-purge toggle + age input (7d
floor, 10y ceiling, 365d default), with a save-toast on every change.
The bulk "Purge old" button lives on the Archives page header
(rightmost, after Upload 3MF) to match the File Manager pattern —
configuration in Settings, one-shot action on the page.
- New PurgeArchivesModal mirrors PurgeOldFilesModal: live preview (count
+ total size freed + sample filenames) debounced at 300ms, amber
"hard-delete, no undo" warning.
- Admin-only UI gates on archives:purge via the standard hasPermission
hook; Permission TS union updated.
- i18n blocks across all 8 locales (en/de full, other 6 English
fallback per project convention).
Docs
- CHANGELOG entry under 0.2.4b1 following the existing library-trash
entry.
- bambuddy-wiki archiving.md gains a new "Auto-Purge" section.
- bambuddy-website features.html gets a matching bullet.
Verification: python -m ruff check backend/app/ clean; 25 integration
tests pass (8 archive_purge + 17 library_trash regression); npm run
build clean.

● feat(#1008): library trash bin, admin bulk purge, auto-purge setting
Library files now move to a configurable-retention trash bin on delete
instead of being hard-deleted from disk (default 30 days). Admins get a
"Purge old" bulk action on the File Manager with a live preview, plus an
optional auto-purge setting in Settings → File Manager that runs the same
operation once per 24h when enabled (default off). Regular users see and
manage their own trashed files; admins see everyone's. External (linked)
files bypass trash since their bytes aren't under Bambuddy's control.
- New `library:purge` permission (admin-only by default)
- Nullable indexed `deleted_at` column on library_files; dialect-aware
ALTER TABLE so the column actually gets added on PostgreSQL (raw
DATETIME is SQLite-only syntax)
- New `LibraryFile.active()` classmethod; every query site routed through
it so trashed rows don't leak into listings, print dispatch, MakerWorld
dedupe, or stats
- Trash page: select-all + bulk restore/delete, per-row checkboxes, wider
layout so datetime columns don't clip
- Auto-purge: 24h throttle via `library_auto_purge_last_run` setting so
the 15-minute sweeper cadence still runs the purge at most once per day
- Save toast wired into every trash/auto-purge setting change
- 17 new backend integration tests (service + routes + auto-purge throttle),
8 new frontend tests, localised across all 8 UI languages
- Wiki + website feature entries updated

Feature/makerworld (#1099)
* feat(makerworld): URL-paste import and print for MakerWorld models
Add a dedicated /makerworld sidebar page where users paste a MakerWorld
model URL and get the full plate list + one-click "Import to Library" or
"Print Now". Closes the workflow gap that kept LAN-only users on the
Bambu Handy app solely for MakerWorld download-and-send.
The authenticated tier reuses the existing Bambu Cloud token that
Bambuddy already stores for firmware checks and slicer settings --
MakerWorld shares the same auth backend, so the same JWT works there.
No separate OAuth flow, no companion browser extension, no credential
hijack. Anonymous users can still paste a URL and see model metadata;
the 3MF download itself requires the Cloud login.
Print Now hands off to the existing PrintModal (plate picker + AMS
mapping + dispatch) so multi-filament models work via the same code
path as library-file prints. Imported 3MFs are stored through a new
shared save_3mf_bytes_to_library() helper so the multipart upload
route and the MakerWorld import route don't duplicate 3MF parsing +
thumbnail extraction logic.
LibraryFile gains indexed source_type + source_url columns. Re-pasting
a URL for a model already in the library returns the existing row
instead of re-downloading -- dedupe is by canonicalised URL, not SHA256,
because MakerWorld's download URLs are signed and change per request.
Thumbnail proxy (/makerworld/thumbnail) hot-links through the backend
instead of directly to makerworld.bblmw.com -- the SPA's img-src CSP
stays strict and users' IPs don't hit MakerWorld's CDN logs. The
endpoint is intentionally unauthenticated since <img> tags can't carry
a Bearer token; SSRF-guarded by a CDN host allowlist so it can't be
used as a generic proxy.
Search and browse-catalogue are explicitly out of scope. The public
design/search endpoint returns empty results from server-originated
requests (likely needs csrf/session state reproducible only from a
real browser), and the __NEXT_DATA__ HTML fallback is blocked by
Cloudflare. URL-paste covers the realistic discovery pattern (Reddit /
YouTube / shared links).
Headers match kloshi-io/makerworld-api-reverse's production-tested set
(User-Agent: 3d-printing-service/1.0, x-bbl-* client identifiers,
Referer). The /instance/{id}/f3mf call includes ?type=download which
community userscripts use to signal legitimate download intent. 418
responses (MakerWorld's CAPTCHA gate) retry once with backoff and then
surface a clear actionable error with an "Open on MakerWorld" fallback
link; we never try to evade bot detection.
Permissions: new makerworld:view (browse metadata, view thumbnails) and
makerworld:import (save 3MFs to library). Administrators and Operators
get both; Viewers get view-only. Migration grants these to existing
groups based on whether they already have library:upload / library:read.
Disclaimer in the UI and wiki page mirrors kloshi's framing: not
affiliated with or endorsed by MakerWorld or Bambu Lab, interoperability
only, not intended to circumvent access controls.
Tests: 30 backend (service + routes) + 4 frontend. Full backend suite
(1931 tests) clean. Frontend build clean.
* feat(makerworld): ship working URL-paste import via api.bambulab.com iot-service
The MakerWorld integration shipped in 0.2.4b1 dev was broken for most
public models: the makerworld.com/design-service path returns "Please
log in to download models" even with a valid Bambu Cloud bearer,
because it's cookie-gated behind Cloudflare. Published reverse-
engineering projects work around this by pasting browser cookies; we
route around it entirely by using the api.bambulab.com/iot-service
endpoint (documented by Pr0zak/YASTL#51), which accepts the same
bearer Bambuddy already has and returns a presigned S3 URL.
Working flow:
GET api.bambulab.com/v1/design-service/design/{id} → metadata
GET api.bambulab.com/v1/iot-service/api/user/profile/{pid}?model_id=<str>
Authorization: Bearer {cloud_token} → signed S3 URL
urllib.request (no redirects, no query re-encoding) → bytes
Notes on each step:
- The model_id query param is the alphanumeric string from the
design response (e.g. US2bb73b106683e5), NOT the integer designId
from the /models/{N} URL. The import route fetches design metadata
first to get it.
- S3 presigned URLs MUST be fetched with urllib (not httpx/curl_cffi)
because the signature is computed over exact query-string bytes;
any normalising encoder breaks it with SignatureDoesNotMatch 400s
(YASTL#52 hit the same issue). Wrapped in a no-redirect opener so
the .amazonaws.com host allowlist guarantee isn't bypassed by a
302 elsewhere.
- The canonical source_url now includes profile_id so different
plates of the same model get distinct library entries. Older rows
from dev builds keep the model-level URL; the resolve endpoint's
"already imported" check LIKEs both shapes.
UI rebuild:
- Per-plate Save + Save & Slice in Bambu Studio / OrcaSlicer (the
plate is unsliced source, so "Print Now" was misleading and is
replaced by an explicit slicer hand-off).
- Import all plates with sequential progress.
- Folder picker (default: auto-created top-level "MakerWorld"
folder, created on first import, folder tree invalidated so
File Manager shows it immediately).
- Image gallery per plate with keyboard-navigable lightbox.
- Recent imports sidebar (sticky on lg+, vertical list with
jump-to-library / slicer / open-on-makerworld icons).
- Inline follow-up actions on imported plate rows so the user
doesn't scroll back to a top-of-page card.
- Per-plate delete via the standard ConfirmModal (no window.confirm).
- Elapsed-time + phase label during import so the 10-30s synchronous
POST doesn't feel frozen.
- URL-change detection drops the preview when the pasted URL
diverges from the resolved one.
Security hardening (found in review):
- DOMPurify.sanitize on the MakerWorld HTML summary before
dangerouslySetInnerHTML (user-authored content).
- <img> tags in that HTML routed through the thumbnail proxy so
the SPA's img-src 'self' data: blob: CSP isn't widened.
- /makerworld/thumbnail uses follow_redirects=False (the host
allowlist only covers the initial URL).
- 3MF CDN fetch strips the bearer (signed URL is the credential).
- S3 fetch uses a no-op HTTPRedirectHandler for the same reason.
- Upstream filename is os.path.basename'd before persisting.
Tests: 46 backend service unit tests, 19 route tests, 12 frontend
tests — all passing. All user-facing strings localised across the

fix(queue): prevent duplicate dispatch and stale progress on batch prints
Two related queue issues surfaced when scheduling an ASAP print with
quantity > 1 on an H2D:
1. Double-dispatch — both items in the batch ended up in 'printing'
status on the same printer, logged as "BUG: Multiple queue items in
'printing' status for printer N". The scheduler seeded its busy
set empty each tick and relied on _is_printer_idle() reading live
MQTT state, but H2D / P1 series lag several seconds between the
print command and IDLE → RUNNING, so the next check_queue() tick
saw IDLE and dispatched the second batch item onto the already-
running printer. check_queue() now seeds busy_printers with every
printer_id that has a row in 'printing' status before iterating,
so any printer with an outstanding dispatched job is excluded
regardless of what MQTT currently reports.
2. Progress bar flashed 100% — immediately after dispatch the queue
item's per-row progress bar showed the prior print's final mc_percent
for a few seconds, then snapped back to 0% when the new print
started ticking. QueuePage.tsx now gates progress / remaining_time /
layer fields on status.state being RUNNING or PAUSE; in any other
state (FINISH from the prior print, IDLE, PREPARE while heating)
the bar renders at 0% with no stale ETA or layer count.
Regression coverage added in test_phantom_print_hardening.py
(TestBusyPrinterSeedingFromPrintingItems, 3 tests): seeding query
returns only printers with 'printing' rows, empty when none exist,
and end-to-end check_queue() does not call _start_print for a pending
item whose printer already has a 'printing' row even when
_is_printer_idle() is forced True.

refactor(gcode-viewer): archive-scoped previews, bed from capabilities, plate picker
Reshapes the embedded PrettyGCode viewer (landed in #963) into a focused archive-preview tool, matching Bambuddy's data model instead of the OctoPrint-style "connected-printer + library file picker" flow it shipped with. Reached only from the Archives page 3D-preview button; URL /gcode-viewer?archive=<id>[&plate=<N>]. Backend: - /archives/{id}/gcode accepts ?plate=N and resolves the filename by parsing the suffix as int, so zero-padded names like plate_01.gcode are found when the plates endpoint reports index 1. - /archives/{id}/plates gains top-level has_gcode: bool. Source-only 3MFs (PNG/JSON fallback path) surface the flag so the frontend can skip the picker instead of sending the user into a dead viewer. - printer_state_to_dict injects name + model into every WS snapshot so consumers render proper labels on the initial tick without racing a separate /printers fetch. - /gcode-viewer (no trailing slash) dropped from the backend so reloads fall through to the SPA catch-all and keep the layout shell; only /gcode-viewer/ (trailing slash) and /gcode-viewer/<path> remain for the iframe + static assets. Frontend: - PlatePickerModal shown only for multi-plate archives with sliced gcode, grid layout with thumbnails matching the Re-print modal. - Source-only archives show a noGcode toast instead of the empty viewer. - ArchivesPage navigate path swapped to /gcode-viewer?archive=<id> with no trailing slash; GCodeViewerPage iframe forwards window.location.search so the archive reference survives both the initial navigate and a full-page reload. - Viewer iframe's auth path: fetch intercept injects Bearer; a 401 redirects to / so the SPA handles login. Viewer adapter: - Stripped the printer selector, WebSocket subscription, library file picker, tryAutoLoadPrintingFile, BAMBU_BED_SIZES, and updatePrinter- Selector. The viewer no longer observes live printer state. - Bed size derived from /archives/{id}/capabilities.build_volume (extracted from the 3MF's printable_area/printable_height), so H2D, H-family, and any future printer render on the correct bed without a hardcoded map. - loadArchiveById accepts a plate param; fetch intercept rewrites __bambuddy_archive_<id>[_plate<N>] to /archives/<id>/gcode[?plate=N]. Nav + locale cleanup: - Sidebar "GCode Viewer" nav entry removed (viewer is archive-scoped now, not a destination page). - 32 orphaned gcodeViewer locale keys deleted across all 8 locales. - platePicker.{title, hint, plateLabel, objectCount, noGcode} keys added in all 8 locales. ArchivesPage: the now-unreachable ModelViewerModal render paths + its showViewer state removed. ModelViewerModal itself stays — File Manager still uses it for library file previews (plate picker + .3mf 3D model). pre-commit: - gcode_viewer/ excluded from trailing-whitespace + end-of-file-fixer so vendored third-party JS libs don't drift away from upstream. Incidental sweeps picked up by pre-commit and kept (unrelated but benign): - NotificationsPage.tsx: single trailing-whitespace line removed. - spoolbuddy/scripts/pn5180_diag.py: dead `import gpiod` dropped — the pn5180 driver module imported at line 27 does its own `import gpiod` and `gpiod.Chip()` calls, so the diag script's top-level import was never referenced. Tests: - 6 new cases in test_gcode_viewer.py for the backend plate / has_gcode behaviour (plate=N resolution, zero-padded filenames, missing-plate 404, no-plate fallback, plate=0 rejection, has_gcode true/false). - 3 new cases in test_printer_manager.py for name/model WS injection. - PlatePickerModal.test.tsx — 6 frontend cases covering render, plate-name composition, onSelect payload, backdrop close, and thumbnail fallback. |

fix(scheduler): watchdog falsely reverts slow H2D dispatches, causing reprints (#1078)
_watchdog_print_start reverted queue items to "pending" at 45 s if gcode_state hadn't changed, assuming the MQTT project_file was swallowed by a half-broken session (#887/#967). H2D Pro firmware (01.01.00.00) routinely keeps state=FINISH for 48-55 s after actually accepting the command before transitioning to PREPARE. The watchdog reverted items the printer had already started physically printing; the archive updated normally via _active_prints, but the queue item was now "pending" again, and the next scheduler tick after plate-clear re-dispatched the same item as if it had never run. With one item left in the queue that looked like a reprint of the just-finished job; with multiple items the symptom was masked by item N+1 getting dispatched during the race. Add a second "command landed" signal: subtask_id advancing past the pre-dispatch value. Bambuddy already mints a unique submission_id per project_file publish (#1042) and the printer echoes it back on the next push_status as soon as it starts processing the command - well before gcode_state transitions on slow-transition models. _start_print now captures pre_subtask_id alongside pre_state and passes both to the watchdog, which exits early on either a state change or a subtask_id advance. Raise default timeout 45 s → 90 s as belt-and-braces for printers that neither flip state nor echo subtask_id inside the polling window. Genuinely half-broken sessions (both signals unchanged across the full 90 s) still revert + force-reconnect exactly as before. Transient subtask_id=None during reconnect is not mis-detected as a change. pre_subtask_id=None falls back to state-only checking so the fix is safe for printers that haven't reported a subtask_id yet. New test_scheduler_watchdog.py pins the eight behaviours that matter: pickup via state change; pickup via subtask_id change with state still FINISH (the exact #1078 case); revert when neither signal changes; default timeout is 90 s; pre_subtask_id=None state-only fallback; current subtask_id=None not treated as change; printer disconnect mid-watchdog leaves DB untouched; item that already moved on is not clobbered. |

fix(printers): Clear-Plate button delayed 30s–5min after print completes (#939 follow-up)
PR #939 added the awaiting_plate_clear gate but stored it on PrinterManager, not on PrinterState. printer_state_to_dict() — which builds every WebSocket printer_status payload — never emitted the flag, so the frontend's WS merge preserved the stale false value. The only path that surfaced true was the 30s HTTP fallback poll, and incoming WS ticks kept bumping React Query's dataUpdatedAt, pushing the refetch out further on chatty printers. Emit awaiting_plate_clear from printer_state_to_dict by reading printer_manager.is_awaiting_plate_clear(printer_id) directly; returns False when no id is passed. No frontend change needed — the existing WS merge carries the flag end-to-end and the button now appears the instant the printer transitions to FINISH. Regression tests assert the WS dict always contains the key and surfaces True when the manager has the flag set for that printer_id. Affects every printer (A1/H2D/X1C) equally — transport-agnostic path. |

fix(dispatch): clean up transient library upload from Direct-Print flow (#730)
The "Print" button on a printer card (and drag-drop-onto-card) used
FileUploadModal to persist the file as a LibraryFile, then dispatched
through POST /library/files/{id}/print. The LibraryFile row + disk file
were left behind after every one-off print, polluting File Manager with
entries the user never asked to save.
FilePrintRequest.cleanup_library_after_dispatch (default False) opts
into post-dispatch cleanup. When set, _run_print_library_file stages
db.delete(lib_file) in the same transaction as archive_print so a
mid-flight FTP / start_print failure rolls both back cleanly, commits
together, then unlinks the library disk file + thumbnail after commit
succeeds. External library files (is_external=True) are never touched.
Only the Printers-page Direct-Print PrintModal sets the flag. Every
other api.printLibraryFile caller (File Manager Print, Project Detail
Print) leaves it unset — their entries are there by user intent.
Also moves formatPrintName out of PrintersPage.tsx into a new
utils/printName.ts module —

feat(printers): show plate name on card for multi-plate active prints (#881)
When two printers were running different plates of the same multi-plate 3MF, the Printers page cards displayed the same file name on both and there was no way to tell them apart. The Queue view already had this information by cross-referencing the archive's plate list; the card didn't have the linkage. Expose `current_archive_id` (resolved by matching the MQTT `subtask_id` against `PrintArchive.subtask_id` — the bridge introduced in #972 for restart-resume) and `current_plate_id` (parsed from `gcode_file` by a new shared `parse_plate_id` helper) on the status endpoint. The helper is also called from the WebSocket push path so plate transitions reflect within 100 ms instead of waiting 30 s for the next REST poll; the archive id itself stays REST-only since it's stable for the life of a print and shouldn't make the push path touch the DB. The card fetches plate metadata via the same `api.getArchivePlates()` call QueuePage uses — shared React Query cache keeps it cheap across polls — and renders the actual plate name (or a "Plate N" fallback) only when `is_multi_plate` is true. Single-plate prints stay clean. Falls back to the previous `plate_N.gcode` regex path when there's no archive linkage (e.g. prints started directly from the printer LCD). Tests cover the plate-id extraction across Bambu Studio path shapes (backend parse_plate_id, printer_state_to_dict wiring) and the label override precedence in formatPrintName (frontend). |

fix(printer): bed-jog "Home Z" could crash bed into toolhead on H2C/H2D/H2S/X1 (#1052)
Critical safety fix. The bed-jog dialog's "Home Z" button sent a bare
`G28 Z` over gcode_line. On Bambu printers where the Z endstop is at
the top (bed moves UP into it — H2C, H2D, H2S, X1 family), `G28 Z`
skips the toolhead-park step that a full `G28` runs first, so the bed
rises at full speed with nothing getting out of the way. The reporter
only escaped damage because the toolhead happened to be parked on the
purge chute.
The /printers/{id}/home-axes endpoint and BambuClient.home_axes() now
always send bare `G28` regardless of the axes argument, triggering the
firmware's safe multi-step routine (park toolhead → home XY → home Z).
The axes argument is kept for API compat but ignored; invalid values
still return 400.
Frontend retitles the button "Auto Home" and updates the dialog copy
in all 7 locales so users aren't surprised when X/Y motion happens
before Z. Parameterized regression test asserts z/xy/all all produce
bare G28.

fix(smart-plug): restore MQTT subscriptions for per-type topic configs on startup (#1010)
Users integrating a Shelly plug through an external MQTT broker (ioBroker, Zigbee2MQTT, HA's MQTT broker, etc.) lost the plug's power/state/energy readings after every Bambuddy restart. The only fix was opening Settings → Smart Plugs, renaming the topic to a dummy value, saving, renaming back, and saving again. Root cause: three code paths configure an MQTT smart plug's subscriptions — the startup restore in main.py, the create route, and the update route — and they had drifted. The create/update routes used the newer per-type model (mqtt_power_topic / mqtt_energy_topic / mqtt_state_topic with per-type paths, multipliers and mqtt_state_on_value) while the startup restore was still on the legacy single-topic model. Worse, the restore loop short-circuited on `if plug.mqtt_topic:`, skipping any plug whose topics were only set in the new per-type fields — exactly the shape of a Shelly-via-ioBroker config, which publishes power and state on separate topics. The "rename, save, rename back" workaround routed through the update endpoint and re-established the subscription the correct way. Extracted the topic-resolution + service.subscribe() call into subscribe_plug_to_mqtt() in mqtt_smart_plug.py and routed all three paths through it so the schema can't drift again. The helper keeps the legacy `mqtt_topic` field working as a fallback for all three data types — matching the behaviour the startup restore used to have via subscribe()'s internal `effective_*_topic or topic` collapsing, and matching the change-detection dict already used during updates. Regression tests cover: per-type topics restored without a legacy topic, legacy single-topic backward compat, per-type multipliers overriding legacy, per-type winning when both are set, the empty-config skip case, and topic-list de-duplication. |

fix(archive): truncation of large 3MF uploads on sendfile short-return (#1032)
On bare-metal Raspberry Pi OS bookworm / armv7l / Python 3.11, 3MF
files larger than a few megabytes arrived complete via the
virtual-printer FTP server but the copy into data/archives/ was
silently truncated. The archive row was still written, the printer
card looked fine, and the problem only surfaced later when opening
the archive — the subsequent zipfile.ZipFile() in
GET /archives/{id}/plates raised BadZipFile and the UI came up blank
with no thumbnail, plate list, or filament data.
Two things conspired:
1. archive_print() used shutil.copy2, which takes Python's sendfile()
fast path on Linux. On the reporter's kernel/fs combination
sendfile returned a short count on the first call for the upload
sizes hit in practice and the destination ended up truncated.
Small files completed in one syscall and were fine.
2. ThreeMFParser.parse() caught the resulting BadZipFile in a bare
`except Exception: pass`, so the archive pipeline kept going with
empty metadata and left the bad file on disk — nothing in the
logs hinted anything had gone wrong until a support bundle came
in and the "Failed to parse plates" warning fired much later.
The archive copy is now an explicit chunked read/write with fsync —
sendfile is not in the path. After the copy, if the source was a
valid ZIP but the destination isn't, we refuse to create the archive
row, remove only the truncated file (and the archive directory if
empty — archive_dir is created with exist_ok=True so rmtree would be
unsafe if a same-second same-filename collision happened), and log
both sizes at ERROR so the condition is obvious in future support
bundles. The parser's silent catch now logs at WARNING for the same
reason.
All nine archive_print() call sites already check `if archive:` or
`if not archive:`, so returning None for corrupted ZIPs propagates
cleanly without behaviour changes elsewhere.
Regression tests cover single-chunk and multi-chunk copies, mtime
preservation via copystat, overwrite of an existing destination, a
ZIP roundtrip through a multi-megabyte 3MF, the new parser WARNING,
and a truncation sentinel verifying that zipfile.is_zipfile() flips
to False on a half-written ZIP — the exact post-condition
archive_print now trusts.

fix(firmware): parse P2S/X2D wiki anchors without dash and full-width parens (#1030)
The wiki scraper silently returned no versions for P2S and X2D, causing
Bambuddy to fall back to the Bambu Lab download page, which still listed
01.01.01.00 as "latest" even though 01.02.00.00 shipped on 2026-04-09.
Two regex mismatches in _fetch_all_versions_from_wiki():
1. Heading anchor ids require an optional dash between version bytes and
date. H2D/X1/H2C/H2S use "h-01020000-20260409"; P2S and X2D publish
"h-0102000020260409" (no dash).
2. The text fallback only matched ASCII parens around release dates, but
P2S, X2D, A1 and A1-mini render dates in full-width parens (YYYYMMDD)
(U+FF08/U+FF09).
Anchor regex now accepts an optional dash; fallback accepts both paren
styles. Added regression tests for both shapes.

fix(mqtt): unique per-submission IDs for archive reprints (#1011)
Archive reprints and library-file prints built the MQTT project_file command with hardcoded project_id="0", subtask_id="0", task_id="0". Printers key per-job state (including gcode_start_time) on those IDs, so reprints looked like continuations of the same job and third-party MQTT observers (OctoEverywhere) reported compounding durations across repeat replays — a 40 min job reprinted from archive showed ~1h40m, and a second reprint of the same file showed ~4h. BambuStudio mints fresh IDs per submission; bambu_mqtt.start_print() now does the same using an epoch-millisecond timestamp for all three fields. md5 is deliberately left empty to avoid activating firmware md5-validation against a digest we can't compute without re-reading the upload. Added 6 regression tests in TestStartPrintUniqueIdentityFields covering non-zero IDs, md5 stays empty, uniqueness across successive submissions, numeric-string format, and blast-radius guard on unrelated payload fields. Updated CHANGELOG. |

fix(obico): revert POST-bytes approach — Obico /p/ is GET-only
The 0.2.3b4 #1003 "fix" POSTed JPEG bytes as multipart form data,
but Obico's /p/ endpoint is declared methods=['GET'] upstream and
reads ?img=URL from the query string. Every POST was 405'd by
Flask's router before any handler ran, which is why the Obico
container logs were silent while Bambuddy kept reporting
"ML API call failed for printer N:" with a blank suffix —
raise_for_status() on the 405 produced an exception whose str()
rendered empty.

fix(obico): exclude snapshot capture PIDs from stream cleanup (#172)
The periodic camera cleanup task scans /proc for ffmpeg processes and kills any not in the active-streams registry. The Obico detection service's capture_camera_frame_bytes() spawns short-lived ffmpeg for snapshots but never registered the PID — so cleanup killed it as "orphaned" mid-capture (SIGKILL, exit -9), producing false errors and missed detection frames. Track capture PIDs in _active_capture_pids and exclude them from the cleanup kill list. |
