Continue Auto-Drying while a print is running on capable hardware.
New Settings > Print Queue > "Continue drying while printing" toggle
(default OFF). Extends _check_auto_drying in print_scheduler.py to
evaluate running printers when supports_drying_while_printing(model,
firmware) returns true. Strict allowlist verified per Bambu wiki
release notes for "Print While Drying" / "printing while filament is
drying": H2D 01.03.00.00+, H2C/H2S/P2S/H2D Pro 01.02.00.00+, X2D/A2L
01.01.00.00+, X1C 01.11.02.00+. P1*, A1, A1 Mini, X1 (non-C), X1E
intentionally excluded. Mid-print drying temperature is capped at
max(40, preset_temp - 5) to protect spools from heat damage inside the
hot enclosure during a print, matching Bambu's own "lower drying
temperature during printing" guidance.
Rotate-spool toggle in the drying popover is now disabled when any tray
in the targeted AMS has filament threaded into the feed tube
(tray.state === 11). The whole AMS rotates as one mechanism, so a
single loaded slot locks the entire unit. Previously the toggle was
always clickable and the firmware rejected with dry_sf_reason=[3]
(ConsumableAtAmsOutlet) after the click. The first cut keyed on the
printer-level tray_now but missed the H2D's typical post-print state
where tray_now resets to 255 while filament stays in the tube — the
per-tray state field reports it correctly. Submission also clamps
rotateTray off so a stale-true state from a previous AMS can't leak
through.
Backend: supports_drying_while_printing in printer_manager.py covers
display names and internal SSDP/MQTT codes (O1D, O1E/O2D, O1C/O1C2,
O1S, N6, BL-P001, N7, N9). New print_drying_enabled boolean in
settings schema. Frontend: toggle on SettingsPage, gate + clamp on
PrintersPage drying popover using existing amsData cache. i18n: 3 new
keys x 11 locales, no English fallback. Tests: 7 cases on the gate
matrix (TestSupportsDryingWhilePrinting), 4 cases on the scheduler
mid-print path (TestMidPrintDrying), 9 cases on the rotate gate state
transitions. Full backend pytest -n 30 green (4251/4251), ruff clean,
frontend npm run build clean, i18n parity 5355 leaves per locale.
Operator-flipped out-of-service state per printer for three scenarios:
parallel Bambuddy installs (dev + prod where the printer rejects all
but one MQTT client), printers under repair, and temporary suspension.
The backend Printer.is_active gate has shipped since day one and is
already honoured by every consumer — MQTT (printer_manager), queue
dispatch (print_scheduler, print_queue), metrics, scheduler, picker,
backup, maintenance dashboard. The missing piece was UI exposure.
Three entry points to flip is_active:
- Three-dot overflow menu (Enter / Exit maintenance mode, wrench icon)
- Exit button inside the in-card amber panel
- Checkbox in EditPrinterModal
Card UI: expanded mode shows an amber panel (Wrench + "In Maintenance"
+ subtitle + Exit) where the cover/progress container would normally
render — same height, no layout shift. Compact mode shows an amber
pill in place of the progress bar. Header pill swaps Connected/Offline
for "Maintenance" and the diagnostic CTA is suppressed (deliberate
state, not involuntary offline). HMS / Queue / Firmware pills fall
away naturally via the existing status?.connected gates.
Mid-print entry (RUNNING / PAUSE) triggers a confirmation dialog —
disconnecting MQTT mid-print stops progress tracking and completion
notifications for the in-flight job. Idle / FINISH / FAILED skip the
dialog and toggle directly.
Scope: no backend change, no new permission, no behaviour change for
any other consumer. PrinterCreate.is_active?: boolean added to the
TypeScript surface so the field flows through api.updatePrinter.
New PrinterSensorHistory table + 60s recorder + GET/DELETE /printer-sensor-history
route gated behind a new PRINTER_SENSOR_HISTORY_READ scope (separate from AMS). UI
adds a 10x10 LineChart icon on each heater tile - click body opens the existing
target-temp popover unchanged, click icon opens a HeaterHistoryModal mirroring the
AMSHistoryModal shape (kind toggle + 6h/24h/48h/7d range + current/avg/min/max +
recharts line for value + dashed target). Read-only X1C/P2S chamber tile finally
gets an interaction. Retention configurable via printer_sensor_history_retention_days
(default 30, sibling of ams_history_retention_days). 8 new i18n keys translated in
all 11 locales, parity green. 4 backend + 6 frontend tests added; full pytest -n 30

PR #1529 added the Windows installer but the rendered README sections
had a stray blank line inside the install one-liner's code fence and
the cross-platform Service Management / Updating / Troubleshooting
sections still only covered Linux + macOS + Docker. Fold in Windows
entries (Start-Service, Get-NetTCPConnection, NSSM runtime log path)
and link the README description to the Windows Installer wiki page so
users know where the parameter reference and unattended examples live.
Re-slicing a 3MF authored for a single-nozzle printer (X1C, P1S, A1, P2S)
onto a dual-nozzle printer (H2D / H2D Pro) — or vice versa — previously
failed with "G-code in unprintable area of multi-extruder printers" (the
source's bed-coordinate layout lands in the H2D's per-nozzle dead zone)
or, on multi-color projects, a hard SIGSEGV inside the slicer's ZFiller
polygon-clipping. Earlier shipped a fail-fast 400 guard; this drop lifts
it and actually does the conversion by forwarding the sidecar's existing
--arrange flag when the source and target nozzle classes differ. BS
itself reconciles the embedded project_settings.config against the new
printer that way, the same way the GUI's "Switch Printer" operation
does. The guard becomes a kept-for-compat no-op.
Slice-all-plates added to the SliceModal: a checkbox for multi-plate
sources sends plate=0 to the backend, which forwards --slice 0 to the
BS CLI. Same-class slice-all produces one multi-plate output 3MF in a
single sidecar call. Cross-class slice-all loops per plate (BS's
--arrange is project-wide and would otherwise consolidate every plate's
objects onto one bed) and merges the per-plate outputs into one
multi-plate 3MF locally via the new merge_plate_3mfs helper. The toast
shows "Plate 2 of 5 — Generating G-code (47%)" through the loop.
Three side fixes surfaced during testing:
- substitute_unused_plate_filaments overwrites unused-slot filaments
with the slot-1 selection before slicing so BS's loaded-filament
temperature validator doesn't reject a PLA print whose unused slot 2
defaulted to ABS in the dropdown
- re-sliced archive thumbnail now prefers the source's per-plate
render (Metadata/plate_N.png) over the project-wide MakerWorld cover
art, because BS CLI with --arrange skips writing a fresh per-plate
preview
- re-sliced archive bed_type now lifts from the sliced output's
curr_bed_type onto the PrintArchive column the card actually reads
Schema: SliceRequest.plate range relaxed from ge=1 to ge=0 to admit
the "all plates" sentinel; SlicerApiService.slice_with_profiles /
slice_with_bundle take an `arrange` parameter.
Tests: 26 in test_slicer_3mf_convert (count / merge / substitute /
extract), 3 in test_slicer_api (arrange wire format), 9 in
test_library_slice_api (guard no-op, bed_type lift, thumbnail
fallback, new cross-class slice-all loop integration test), 2 in
test_archive_service (Auxiliaries fallback), 4 in SliceModal.test
(plate=0 toggle), 2 in SliceJobTrackerContext.test (multi-plate toast
prefix). 659 backend + 42 frontend green; backend ruff clean,
frontend build clean, i18n parity green at 4984 keys × 9 locales.
Statistics now aggregate over PrintLogEntry (one row per print event,
the same table backing the global Print Log) rather than PrintArchive
(one row per file). A reprint creates a new PrintLogEntry instead of
overwriting the source archive's runtime fields, so:
- a 100 g successful print + a 10 g failed reprint correctly sums to
110 g / 2 prints / 1 successful / 1 failed in Quick Stats and the
Prometheus /metrics endpoint (previously the failed reprint silently
replaced the source archive's data; totals dropped from 100 g to 10 g)
- the archive's card cost/energy_kwh are preserved on reprints (only
the first run writes them); per-run actuals live on PrintLogEntry
- failed/cancelled/stopped reprints record partial-aware filament: sum
of tracked spool deltas when inventory is set up, else estimate
scaled to progress%, else None — prevents the full slicer estimate
from inflating totals on a print that stopped at 10 % progress
PrintLogEntry gains six columns: archive_id (nullable FK, ON DELETE
SET NULL so log entries survive archive deletion preserving #1343
soft-delete-vs-stats decoupling), cost, energy_kwh, energy_cost,
failure_reason, created_by_id. Idempotent SQLite + Postgres migrations.
New per-archive surface:
- archive list response carries run_count / last_run_at /
total_filament_actual_grams / successful_run_count / failed_run_count
via a single batch JOIN, no N+1
- new GET /archives/{id}/runs endpoint returns every PrintLogEntry for
the archive (ARCHIVES_READ permission, newest-first ordering)
- archive cards render an orange "N prints" badge for archives with
more than one run; clicking the badge opens a dedicated PrintLogModal
with date/status/duration/filament/cost columns plus failure_reason
under failed runs. Also reachable via the context menu's new "Print
Log" entry (works for single-run archives too), and embedded at the
top of the Edit Archive modal for context.
The purge_stats=true delete path now hard-deletes linked PrintLogEntry
rows up front so the archive's contribution truly leaves the totals;
without it, ON DELETE SET NULL would orphan the runs and leave them
counting toward stats.
Closes the longest-standing inventory gap — finding a specific spool
in a closet of 50 partials. Per-spool icon button on every inventory
card and table row, plus a "Print labels..." header action that opens
a multi-select picker pre-loaded with the currently filtered spools.
Four pre-built templates: AMS holder (30 x 15 mm) for the popular
Makerworld AMS Filament Label Holder, single box label (62 x 29 mm)
for Brother PT/QL or Dymo small labels, Avery L7160 (A4, 21 per
sheet), and Avery 5160 (US Letter, 30 per sheet). Each label carries
the colour swatch (with multi-colour gradient stripes for spools
with extra_colors set), brand, material, name, the *spool ID*
(bsaunder's articulated user-need: telling 8 spools of "PLA White"
apart, especially partials), and a QR code that deep-links to
/inventory?spool=<id> for phone-scan round-trips. Box-label adds
storage location; AMS-holder drops the QR — at 30 x 15 mm there is
no room for swatch + text + QR without truncating away the spool ID,
and AMS-bay identification is at arm's length where the swatch and
ID are enough.
Server-side rendering via ReportLab + qrcode (already a dep). Pure
Python, no headless browser, no system libs. Output is byte-identical
across browsers, Avery sheets align to <0.1 mm, and bulk export is
one click for one PDF. Two endpoints — POST /inventory/labels (local
DB) and POST /spoolman/labels (Spoolman-backed) — gated on
INVENTORY_READ, capped at 500 spools per request, returning
application/pdf via StreamingResponse. The renderer is decoupled
from the SQLAlchemy model via a LabelData dataclass so the same code
path serves both modes.
Modal picker scales to large libraries: search (substring match
across name / brand / #ID), material filter chips derived from the
visible spools, additive Select-all-visible / Deselect-visible /
Clear-all actions so selections survive filter changes. Restyled
twice in development — first cut used generic Tailwind which clashed
with the inventory's bambu-dark palette; second cut switched to
bambu-dark-secondary / bambu-green / bambu-gray to match.
Two render bugs found during visual inspection of generated PDFs and
fixed before commit:
1. AMS-30x15 template originally produced labels with only swatch
+ QR and no text at all — the side-by-side layout left <5 mm
for the text column, so the renderer bailed without drawing
anything. Layout split into tight (h<20mm) and roomy (h>=20mm)
regimes; tight regime drops the QR and gives the right column
to brand + material + a 13pt-bold spool ID.
2. Box-62x29 template aggressively truncated text — swatch + QR
each at ~14 mm on a 26mm-tall label squeezed the text column
to ~16 mm, turning "Polymaker Ivory" into "Polymak..." and
"Polymaker . PLA . Matte" into "Polymaker ...". Swatch capped
at 16 mm, QR capped at 18 mm and constrained to ~20% of width,
leaving the text column ~30 mm — full names render without
truncation.
Both bugs pinned by regression tests in test_label_renderer.py that
render with pageCompression=0 so the resulting PDF bytes contain the
text as ASCII and `assert b"Polymaker" in pdf` works.
The Tailscale toggle was supposed to obtain a publicly-trusted Let's Encrypt
cert via `tailscale cert` so users wouldn't need to import Bambuddy's CA into
the slicer. End-to-end testing showed this was always going to fail:
- Bambu Studio and OrcaSlicer refuse hostname input in the Add Printer
dialog (IP-only).
- Their printer-MQTT trust path validates only against the bundled BBL CA
store (`printer.cer`), NOT the system trust store. Confirmed against
ClusterM/open-bambu-networking's clean-room reimplementation:
`mosquitto_tls_set(BBL_CA)` + `verify_peer=1` + `tls_insecure=true` —
chain validation against BBL CA only, hostname check intentionally
skipped (because Bambu's printer cert CN is the device serial).
- LE certs don't chain to BBL CA, so the slicer rejects with the
well-known "-1" before any hostname/IP logic runs.
The cert-import step is unavoidable; LE provisioning was dead code for slicer
connections. Pivot:
- Toggle stays as an informational marker — when ON, the VP card surfaces
the host's Tailscale IP + MagicDNS hostname so users know what to paste
into the slicer.
- Cert is always self-signed (signed by `bbl_ca`).
- Tailscale exposure is via the existing bind_ip dropdown, which already
includes `tailscale0` IPs.
- Tailscale's role is strictly network reach — same trust burden as LAN.
Backend cuts:
- `tailscale.py`: `provision_cert`, `ensure_cert`, `cert_needs_renewal`,
`_FQDN_RE`, `_HTTPS_DISABLED_RE`, `TS_CERT_EXPIRY_THRESHOLD_DAYS`,
`cryptography` import. Keep `get_status` and `TailscaleStatus`.
- `certificate.py`: `ts_cert_path`, `ts_key_path`, `use_tailscale_cert`.
- `manager.py`: `tailscale_fqdn` field, `_cert_renewal_task`,
`_cert_restart_task`, `_cert_renewal_loop`, `_restart_for_cert_renewal`,
`_cancel_renewal_task`, `_cancel_restart_task`. Simplify
`_resolve_cert_and_advertise` to a sync method that just generates the
self-signed cert. Drop `tailscale_disabled` from the change-detection
diff (toggle is informational — no service restart needed).
- `routes/virtual_printers.py` + `routes/settings.py`: drop the
`tailscale_not_available` 409 guard on toggle-enable.
Frontend cuts:
- `VirtualPrinterCard.tsx`: FQDN/IP display sourced from
`multiVirtualPrinterApi.getTailscaleStatus()` (host-level) when toggle
is ON, instead of `printer.status.tailscale_fqdn` (cert side-effect,
no longer populated). Drop the `tailscale_not_available` toast handler.
- `api/client.ts`: drop `tailscale_fqdn` from the VP status type.
- i18n: rewrite `tailscaleDisabled.description` in all 8 locales to drop
the "no cert import" promise. Remove `toast.tailscaleNotAvailable` key.
Docs:
- Wiki `features/virtual-printer.md`: rewrite the entire Tailscale section
— remove the LE-cert + HTTPS-Certs-toggle + tailscale-cert-operator
steps, document the toggle as informational, keep the Docker socket
mount + LXC TUN troubleshooting (those still apply for daemon
reachability).
- README: drop "the Tailscale benefit here is the tunnel, not cert-import
elimination" framing in favour of "surfaces the IP for paste into
slicer; CA import unchanged because BBL CA store, not system trust
store, is what gets validated".
Tests:
- `test_tailscale.py`: reduced to surviving `get_status` cases (binary
missing, command fails, success, empty DNSName, malformed JSON).
- `test_virtual_printer.py::test_sync_from_db_restarts_on_tailscale_disabled_change`
→ `test_sync_from_db_does_not_restart_on_tailscale_toggle` (toggle is
informational; `remove_instance` must NOT be called).
- `test_virtual_printer_api.py::TestVirtualPrinterTailscaleGuardAPI` →
`TestVirtualPrinterTailscaleToggleAPI` (single test asserts both
directions succeed and daemon is never consulted).
- `VirtualPrinterCard.test.tsx`: mock now stubs `getTailscaleStatus`;
FQDN-copy block drives data through that query.
DB column `tailscale_disabled` is kept (persists toggle state) — Postgres-
safe column drop is harder; future cleanup can remove if the toggle goes
away entirely. LE cert files on disk (`virtual_printer_ts.{crt,key}`) are
left in place per VP — harmless residue, manual cleanup if desired.
Verified: ruff clean, 2484 backend unit tests pass, 17 frontend VP-card
tests pass, frontend build succeeds, live service restart confirms VPs
serve `issuer=CN=Virtual Printer CA` on the Tailscale interface — slicer
trusts the user-imported bambuddy CA and skips hostname checks, so MQTT
connection succeeds end-to-end.
In non-proxy VP modes (Immediate / Review / Print Queue), the slicer now
sees real AMS / FTS / nozzle / k-profile state from the target printer
and streams the live camera — full slicer-as-remote functionality without
giving up Bambuddy's queue / archive / dispatch features.
Architecture (cached-as-base, single source of truth). The bridge caches
the latest real push_status and info.get_version response from Bambuddy's
existing per-printer MQTT subscription — no second session on the printer,
firmware in-flight budget unaffected (#1164). _send_status_report serves
a near-byte-identical copy of the cached push with only the upload-state-
machine fields overridden. Command responses (extrusion_cali_get, AMS
write acks, xcam) fan out raw — they carry sequence_ids the slicer is
waiting on. Slicer-issued commands forward to the printer except
project_file / gcode_file, which still terminate locally because the file
lives on Bambuddy. Camera is a raw TCPProxy on bind_ip:322 → printer:322,
same approach proxy mode uses.
Field-shape gotchas pinned in the bridge module's docstring and the
new test file:
- Real Bambu pushes use json.dumps(indent=4) wire format. Compact JSON
fails BambuStudio's Send pre-flight silently.
- net.info[*].ip is the FTP destination IP (little-endian uint32).
Without rewriting to the VP bind IP, the slicer FTPs straight to
the real printer.
- upgrade_state.sn rewritten to VP serial; AMS-hardware sn fields
(n3f/0.sn etc.) left alone.
- ipcam.rtsp_url passes through unchanged; BambuStudio overrides the
URL host with the device IP it bound on, so :322 lands on the VP's
TCPProxy.
- extrusion_cali_get must forward; answering it locally hides the
user's stored per-filament k-profiles.
Setup nuance for camera: the VP's access code must match the target
printer's because the slicer authenticates RTSPS with whatever access
code is in its profile. MQTT and FTP work either way.
Tested e2e with BambuStudio and OrcaSlicer against H2D (dual-nozzle,
AMS 2 Pro + AMS HT) and X1C across all three non-proxy modes — sync,
send, k-profile lookup, AMS configuration from slicer, and live camera
all work. Proxy mode is untouched: SlicerProxyManager owns its own
proxies and never instantiates SimpleMQTTServer or MQTTBridge.
25 new tests in backend/tests/unit/test_vp_mqtt_bridge.py cover lifecycle,
caching, identity / IP rewriting, wire format, slicer→printer routing,
and the LE-uint32 IP encoder against the real H2D capture value.
The ams_load_filament / ams_unload_filament MQTT primitives existed
in bambu_mqtt.py but were unused — no HTTP route and no UI. Surface
both as POST /printers/{id}/ams/load?tray_id={int} and
POST /printers/{id}/ams/unload, gated on PRINTERS_CONTROL.
Wire them into the existing AMS slot popover (next to "Re-read RFID")
and add a popover wrapper on the external spool slot which had none.
Hidden while the printer is RUNNING, mirroring the RFID re-read
gating. Both buttons enabled when permission is granted; the printer
no-ops gracefully if there's nothing to do (matches BambuStudio).
Dual-extruder H2D Ext-R support is the trickier piece. The existing
ams_load_filament(254) capture came from a single-extruder printer
and used slot_id=254, curr/tar=-1. Captured the Ext-R command from
BambuStudio fresh: it sends ams_id=255, slot_id=0 (the right
extruder index, NOT a slot index), target=255, and curr/tar = the
actual right-nozzle temp (read from state.temperatures["nozzle_2"],
falling back to 215 °C if cold so the printer doesn't reject the
command on a nonsensical temp). Added that as a new branch in
ams_load_filament; the existing tray_id=254 branch is preserved
verbatim — no risk of regression on single-external setups.
Edward's diagnosis was exact: the manual /print-queue/ POST extracts
filament requirements from the 3MF and writes
required_filament_types + filament_overrides + ams_mapping onto the
queue item, but the VP queue-mode write path skipped all of that.
Net effect: scheduler reached its model-only-matching fallback and
auto-dispatched onto whatever printer was free regardless of loaded
colour.
Extract the scheduler's existing _get_filament_requirements 3MF
parser into a shared helper so the VP path can reuse it. VP's
_add_to_print_queue now populates required_filament_types
unconditionally (cheap; helps the scheduler reject obvious type
mismatches) and writes filament_overrides with force_color_match:
true per consumed slot when a new per-VP queue_force_color_match
toggle is on. Default off to preserve current behaviour for
upgraders.
UI: new toggle on VirtualPrinterCard, mode-gated to print_queue,
mirroring the existing auto-dispatch toggle. i18n: en + de
translated, other 6 locales seeded with English copy.
Schema: one nullable column on virtual_printers
(queue_force_color_match BOOLEAN, default 0/FALSE).
11 new backend tests (8 for the extracted parser, 3 for the VP
write path) + 6 new frontend tests (toggle render gating, default
state, click posts queue_force_color_match in update body).
Existing scheduler tests pass against the refactored helper.
README, CHANGELOG, website features page, and wiki virtual-printer
page all updated.
Tim (@turulix) is building a fully automated headless slicing pipeline
against Bambuddy's API and hit the wall flagged in #665: /cloud/* routes
resolve cloud_token per-user from User.cloud_token, but the auth gate
returned None for API-keyed requests, so the route fell back to the
global Settings-table token, which only carries a value in auth-disabled
deployments. Net effect on auth-enabled deployments: API keys reached
the gate just fine, then /cloud/filaments always saw user=None and
returned 401 / empty results — no path to read slicer presets or the
filament catalogue that a CLI workflow needs.
Make API keys carry an owner and route /cloud/* lookups through that
owner; gate the new capability behind an explicit opt-in scope so
existing automation doesn't gain cloud-read access on upgrade.
- APIKey gains user_id (FK to users.id, ON DELETE CASCADE) and
can_access_cloud (BOOLEAN DEFAULT 0). User-delete route also runs an
explicit DELETE FROM api_keys WHERE user_id = ? since SQLite ships
FK enforcement off — same pattern as the existing created_by_id
cleanup blocks.
- New cloud_caller dep on /cloud/* routes resolves to the JWT user OR
the API-key owner stashed by a router-level gate. The auth gate itself
continues to return None for API keys so #1182's surface stays bounded
to /cloud/* — without that bound, any route that fences API keys via
`if current_user is None: raise 403` (e.g. long-lived-token
management) would silently start accepting them.
- The /cloud/* router-level dep enforces three independent fences for
API-keyed callers: user_id IS NOT NULL (legacy keys → 401 with
recreate copy), can_access_cloud=True (otherwise 403), and owner has
cloud_token (existing fence, unchanged). Two extra one-shot fence
errors at create/update time refuse can_access_cloud=True when auth
is disabled or the key is ownerless.
- Frontend: APIKey list shows "Cloud" badge on cloud-enabled keys and
"Legacy" badge on ownerless rows; create form gains an "Allow cloud
access" toggle, default off. New i18n keys in all 8 locales (en + de
fully translated, others seeded with English fallbacks pending native
translation — matches the project's flow for newly-added features).
Migration: two idempotent ALTER TABLE statements + an index on user_id
for the auth gate's owner→keys lookup. Postgres-safe.
Tests: 9 backend integration tests in test_api_key_cloud_access.py
covering creation flags, the three /cloud/* fences, JWT no-op, and
deletion CASCADE; 2 frontend SettingsPage tests pinning the badge
matrix and the create-form contract; 5 daemon unit tests for the
related SpoolBuddy ssh-key sync work that landed in the same branch.
Full backend suite: 3578 passed; full frontend suite: 1597 passed; no
regressions.
Permission semantics for existing keys: keys created before this
release become "legacy" and are rejected at /cloud/* with the recreate
message. Every other endpoint they were used against — queue, status,
control — is untouched.
The FTS routes any AMS slot to either extruder, so AMS info reports
bits 8-11 = 0xE (uninitialized) and ams_extruder_map ends up empty.
The print modal's per-nozzle dropdown filter then hides every loaded
slot, leaving the user with an empty filament dropdown.
Detection: parse print.device.fila_switch from MQTT push_status into a
new FilaSwitchState dataclass on PrinterState; surface it through the
GET /printers/{id}/status response as a nullable FilaSwitchResponse.
Frontend: useFilamentMapping and FilamentMapping skip the per-extruder
filter when fila_switch.installed is true. Slots currently fed into a
track display an [L]/[R] routing badge in the dropdown so the user
can see where the FTS is currently routing them.
Tests: 4 backend unit (TestFilamentTrackSwitchDetection), 2 backend
integration (status route), 2 hook regression, 2 component regression.
Spool and color_catalog rows carry extra_colors (comma-separated hex
stops) and effect_type (14 visual variants: surface effects, sheen,
structural). The shared FilamentSwatch component renders gradient,
conic, effect overlay, and alpha-checkerboard consistently across the
inventory grid, table, group banner, card, ColorSection preview, and
catalog editor. Catalog hex_color accepts #RRGGBBAA so catalog entries
can carry transparency too.
The paste field accepts the exact format 3dfilamentprofiles.com puts on
its filament details pages, so users can copy a multi-colour combo
directly. The effect dropdown spans the full filament-variant
vocabulary -- surface effects (sparkle/wood/marble/glow/matte), sheen
variants (silk/galaxy/rainbow/metal/translucent), and structural
variants (gradient/dual-color/tri-color/multicolor). None of these
fields touch MQTT/firmware -- pure visual hint.
Spool group-key extended to include extra_colors + effect_type so
"Group similar" no longer collapses visually distinct spools.
Migrations: 4 idempotent ALTER TABLE ADD COLUMN (Postgres-safe), plus
ALTER COLUMN hex_color TYPE VARCHAR(9) on Postgres only (SQLite ignores
VARCHAR length).
Tests: 42 new backend (35 unit + 7 integration), 20 new frontend (14
FilamentSwatch + 3 ColorCatalogSettings + 3 InventoryPageGrouping
regression). 3522 backend + 1582 frontend tests pass; ruff clean.
Localised across all 8 UI locales.
Two new project fields: a free-text URL rendered as a one-click
external-link button beside the project name on every card (opens in a
new tab, click is e.stopPropagation()-guarded so it doesn't enter the
project), and a cover photo that replaces the status-icon box with a
square thumbnail.
URL is plumbed through ProjectCreate/Update/Response/ListResponse,
including from-template + create-template flows so it inherits between
a project and its template. Cover photo is not inherited because the
file would be shared on disk between source and copy.
Schema validator rejects anything other than http:// or https://
prefixes -- <a href> rendering would otherwise execute javascript:
/ data: / file: URLs even with React's default escaping. PATCH uses
model_fields_set for the URL field so users can clear it by sending
{"url": null}.
Cover image storage: Project.cover_image_filename references a file
Cover image storage: Project.cover_image_filename references a file
inside the existing archives/projects/{id}/attachments/ dir, but it's
tracked separately from the attachments JSON list so swap/delete on
the cover doesn't perturb the user's other attachments. Three routes
(POST/GET/DELETE /projects/{id}/cover-image) accept only .jpg/.jpeg/
.png/.gif/.webp (no SVG -- SVG can carry script payloads), replace in
place (prior file deleted before the new one lands so repeat uploads
can't accumulate orphans), and self-heal when a DB reference points at
a vanished disk file by clearing the column and 404'ing.
GET cover-image is gated by RequireCameraStreamTokenIfAuthEnabled
(accepts ?token=... query string) -- not the bearer-token gate -- so
<img src> requests work in both auth-on and auth-off configurations.
The frontend wraps getProjectCoverImageUrl with withStreamToken(),
matching the existing pattern from getArchiveThumbnail.
Permissions: PROJECTS_UPDATE for upload/delete/PATCH, PROJECTS_READ

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).
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).
#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.
* 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
8 UI languages.
* - frontend/src/App.tsx — removed the 3 stale <AdminRoute> lines (kept the 3 <PermissionRoute> equivalents). TSC + Vite both clean.
- backend/tests/integration/test_auth_api.py — added # pragma: allowlist secret + # noqa: S106 on the test fixture line that GitGuardian flagged.
