External folder scan now mirrors disk subfolder structure into the folder
tree instead of flattening all files into root. Hidden directories are
filtered, orphaned subfolders are cleaned up on rescan. Fixes#890.
File manager delete endpoints (folder, file, bulk) now commit before
returning the response — previously relied on post-response auto-commit,
causing a race where the frontend refetch arrived before the commit.
New dedicated MQTT methods, API endpoints, and UI buttons for
loading/unloading filament from the external spool holder without
requiring an AMS. Includes state guards to prevent load when filament
is already loaded and unload when nothing is loaded.
Camera snapshot, test, and plate detection endpoints created temporary
JPEG files with default 0644 permissions. Switch from NamedTemporaryFile
to mkstemp with explicit 0600 permissions.
An API key with printer_ids=[] was treated the same as null (global
access) due to a falsy check. Now None means global access and []
means no printer access. Added a startup migration to normalize any
existing [] rows to NULL so they retain their intended global access.
Also fixed the webhook /queue endpoint which used the same falsy
check, allowing []-scoped keys to see all printers.
The bug report endpoints (start-logging, stop-logging, submit) had no
authentication, allowing anyone on the network to enable debug logging,
retrieve sanitized system logs, and trigger bug report submissions when
auth was enabled. All three now require permission when auth is enabled:
start-logging requires settings:update, stop-logging and submit require
settings:read. Endpoints remain open when auth is disabled (default).
Archive upload endpoints used the client-supplied filename directly
in file paths, allowing an authenticated attacker to write files
outside the intended directory (e.g. ../../evil.3mf bypasses the
.3mf extension check). Added _safe_filename() helper that normalizes
backslashes and extracts the basename before constructing paths.
New SJF toggle badge on the queue page. When enabled, the scheduler
picks shorter print jobs before longer ones instead of FIFO. A
starvation guard flags jobs that get skipped once, moving them to
the front on the next cycle so long jobs can't be postponed indefinitely.
- Add print_time_seconds and been_jumped columns to PrintQueueItem
- Cache print duration from 3MF metadata at queue item creation
- SJF query: printer_id, target_model, been_jumped DESC, print_time_seconds ASC, position
- Mark jumped items in-memory after each print start
- Toggle badge on queue page header with live state indicator
- Frontend auto-sorts to match scheduler order when SJF enabled
- Settings schema, boolean parsing, and migration (SQLite + PostgreSQL)
- i18n badge keys for all 7 locales
- 10 integration tests for SJF ordering and starvation logic
- Wiki, website, README, and changelog updated
Display the active database backend (SQLite or PostgreSQL) and its
version in the Database section of the System Info page. SQLite queries
sqlite_version(), PostgreSQL queries SELECT version() and
pg_database_size(). Helps users verify which database is in use.
Bambuddy can now use an external PostgreSQL database via the
DATABASE_URL environment variable. SQLite remains the default.
Dialect-aware helpers handle upserts, PRAGMAs, FTS (FTS5 vs
tsvector+GIN), backup/restore, and health checks. All migration
blocks use savepoints to prevent Postgres transaction poisoning.
Backups are always portable SQLite format regardless of backend.
Cross-database restore imports SQLite backups into PostgreSQL
with automatic boolean/datetime conversion, NOT NULL default
filling, and FK constraint handling.
GitHub backup can now optionally include spool inventory (with usage
history) and print archive metadata as JSON. Both toggles are off by
default. No binary files (gcode/3MF) are included.
When multiple AMS spools match the same type/color criteria, an optional
setting now prefers the spool with the lowest remaining filament. This
helps consume partial spools before starting new ones. Sorting applies
to all matching paths: queue scheduler, print modal, and multi-printer
mapping. Unknown remain values (-1) sort to end.
Admins can now filter the Statistics page by user via a new
stats:filter_by_user permission. A user dropdown appears in the stats
header showing all users plus "No User (System)" for prints without
attribution. The filter applies to all stats widgets, failure analysis,
and CSV/Excel exports. Backend validates the permission on all 4 stats
endpoints, returning 403 if the filter is used without authorization.
Stagger option now available when printing directly to multiple printers,
not just in queue mode. Prints are automatically queued with staggered
start times using group size/interval from Settings. New "Require
plate-clear confirmation" setting lets farm users disable per-printer
plate confirmations so queued prints start automatically on finished
printers.
Also fixes settings API type parsing for require_plate_clear (boolean),
stagger_group_size and stagger_interval_minutes (integer) — without this,
saved values returned as strings would cause the settings toggle to
always show enabled and trigger a permanent save loop.
scan_external_folder stored raw 3MF metadata containing _thumbnail_data
bytes directly in the JSON column, causing a serialization error. Applied
the same clean_metadata() pattern used by upload/zip extraction and
removed the call to the non-existent parser.extract_thumbnail().
The _is_docker_environment() fallback assumed Docker when .git/ was
absent, which is also true for native installs in Proxmox LXC
containers. Replace the .git/ fallback with a check of
/run/systemd/container (only matches docker/podman/oci, not lxc).
Camera streams, snapshots, thumbnails, timelapse videos, photos, QR
codes, and cover images served via <img>/<video> tags were previously
unauthenticated because browser media elements cannot send Authorization
headers. When auth is enabled, these endpoints are now protected by a
reusable stream token (?token=xxx) obtained from POST
/printers/camera/stream-token (requires CAMERA_VIEW permission).
The daemon now collects CPU temp, core count, load average, memory/disk
usage, OS info, and system uptime every heartbeat using stdlib-only reads
from /proc and /sys. Stats are sent as a JSON blob in the heartbeat
payload, stored in a new system_stats TEXT column, and displayed in a
new "System" tab in SpoolBuddy Settings with color-coded usage bars.
Assigning or unassigning a spool now broadcasts a spool_assignment_changed
event to all connected WebSocket clients. The frontend handles this event
by invalidating the spool-assignments and slotPresets caches, so other
open tabs update automatically without a page reload.
External folder scan generated thumbnails for 3mf/stl/gcode files but
skipped image files. Added IMAGE_EXTENSIONS check with
create_image_thumbnail() to the scan loop.
Some printers (e.g. H2D) only send {id, state} in incremental MQTT
tray updates — no tray_type, tray_color, or other fields. When
filament is unloaded (state changes from 11 to 10), the old tray
data persisted indefinitely because the merge logic only updates
fields present in the incoming message.
Backend:
- Detect tray state != 11 without tray_type in incremental updates
and clear stale tray data (bambu_mqtt.py)
- Expose tray `state` field via REST API and WebSocket broadcasts
(printer.py schema, printers.py route, printer_manager.py)
- Include AMS tray content in WebSocket dedup key so load/unload
transitions trigger broadcasts (main.py)
Frontend:
- Add `state` to AMSTray interface (client.ts)
- Show configure/assign buttons for state=10 (spool present, not
loaded) but hide for state=9 (truly empty) on AMS/HT slots
- Hide fill level bar on empty slots
Tests:
- 5 new tests covering state-based clearing, preservation, reload,
and idempotency
Host directories (NAS, USB, network shares) can now be mounted
into the File Manager without copying files. Files are indexed
into the database on scan but read directly from their original
location. Supports read-only mode, hidden file filtering, and
automatic thumbnail extraction for 3MF/STL/gcode.
- POST /library/folders/external — create with path validation
- POST /library/folders/{id}/scan — discover/sync files
- Block uploads, moves, and deletes for read-only external folders
- Never delete actual files from external paths (DB-only removal)
- Purple folder icon + info bar with rescan button in UI
- i18n for all 7 languages
- 19 backend + 11 frontend tests
When a user closed the camera viewer, the stop endpoint killed the
ffmpeg process but never signaled the stream generator's disconnect
event. The generator saw "process died" as a dropped RTSP session
and respawned ffmpeg — up to 30 times per stream. The orphan cleanup
couldn't catch these because they were still tracked as active.
- Add per-stream disconnect events dict so stop endpoint can signal
generators to stop reconnecting before killing the process
- Check if stream_id was removed from _active_streams before
reconnecting (belt-and-suspenders with the event)
- Track frame timestamps per stream_id instead of per printer_id
so stale detection isn't fooled by newer streams for the same
printer
- Reduce stale thresholds from 120s+60s to 60s+30s
- Signal disconnect events from cleanup when killing stale streams
The SSH update set status to "complete" after the daemon had already
restarted and re-registered, overwriting the cleared state so it stuck
forever. Removed the post-restart "complete" write — daemon
re-registration is now the completion signal, clearing any update status.
After an SSH update completed, the UI kept showing "Update complete,
daemon restarting..." and the old "update available" banner because
nothing cleared the stale state. Registration now resets update_status
when the daemon comes back, and WebSocket handlers for spoolbuddy_update
and spoolbuddy_online invalidate the frontend queries immediately.
The daemon's self-update mechanism (git fetch/reset on its own code) was
fragile: .git permission errors, self-modifying code mid-run, hardcoded
main branch. Bambuddy now SSHes into the SpoolBuddy Pi and drives the
update remotely — matching its own branch, with step-by-step progress
via WebSocket.
SSH key pairing is automatic: Bambuddy generates an ED25519 keypair and
returns the public key in the registration response. The daemon deploys
it to authorized_keys on first connect — no manual setup needed.
- New: backend/app/services/spoolbuddy_ssh.py (keypair, SSH commands, update orchestration)
- Rewritten: trigger_daemon_update endpoint uses SSH instead of pending_command
- New: GET /spoolbuddy/ssh/public-key endpoint for manual pairing
- Removed: daemon _perform_update() and cmd=="update" heartbeat handler
- Updated: install.sh — bash shell, sudoers for systemctl restart, .ssh/ setup
- Updated: Dockerfile — added openssh-client
- Updated: frontend — SSH key display, force update button
- Fixed: update check now compares against APP_VERSION, not GitHub releases
The daemon's self-update mechanism (git fetch/reset on its own code) was
fragile: .git permission errors, self-modifying code mid-run, hardcoded
main branch. Bambuddy now SSHes into the SpoolBuddy Pi and drives the
update remotely — matching its own branch, with step-by-step progress
via WebSocket. Install script updated with SSH access, sudoers entry,
and --ssh-pubkey flag for pairing.
The SpoolBuddy daemon update endpoint fetched GitHub releases and compared
them against device.firmware_version, which always showed "up to date"
because the comparison source was wrong. Now compares directly against
APP_VERSION from the running backend, so a daemon at 0.2.3b1 correctly
sees 0.2.3 as an available update.
SpoolBuddy devices can now be updated from Settings → Updates without
SSH access. The daemon picks up an "update" command via its existing
heartbeat, runs git fetch/reset + pip install, reports progress back
to the backend, then exits for systemd to restart with the new code.
Backend: update_status/update_message fields, trigger + status endpoints
Daemon: _perform_update() handler, report_update_status() API method
Frontend: "Apply Update" button with live progress in UpdatesTab
Replace fixed 30-second debug log collection with an interactive
3-step flow: start logging, reproduce the issue, stop & submit.
Users now control timing instead of racing a countdown.
Backend: split _collect_debug_logs() into POST /start-logging and
POST /stop-logging endpoints; add debug_logs field to submit request.
Frontend: 3-step progress indicator with elapsed timer, pulsing
active state, and 5-minute auto-stop. Updated all 7 locale files.
Add a "Rotate spool during drying" checkbox to the manual drying popover
for AMS 2 Pro and AMS-HT units. The firmware-level rotate_tray field was
already sent (hardcoded to false) — this makes it user-configurable.
The checkbox defaults to unchecked and resets each time the popover opens.
Firmware silently disables rotation if filament is currently loaded.
Carbon rods use plain bearings — lubricating them degrades print quality.
Removed the lubrication task from defaults; only "Clean Carbon Rods"
remains. Existing entries are auto-removed on next startup via
ensure_default_types(). Updated wiki link mapping and tests.
Add a speed control badge to the printer monitoring card controls row
that lets users switch between Silent (50%), Standard (100%), Sport
(124%), and Ludicrous (166%) presets during active prints. The badge
displays a gauge icon with the current speed percentage, always visible
but disabled when idle. Includes backend endpoint, optimistic UI
updates, i18n for all 7 locales, and full test coverage.
After assigning a spool to an AMS slot, the Bambuddy UI could show the
wrong filament preset (e.g. "Bambu PLA Matte" instead of "Bambu PLA
Silk") even though the printer was configured correctly.
Two bugs:
1. AssignSpoolModal (PrintersPage hover card path) never saved the slot
preset mapping to the DB, so the display fell back to the old/stale
mapping from a previous manual configuration.
2. AssignToAmsModal (SpoolBuddy path) constructed the preset name from
spool.material + spool.subtype ("PLA Silk") instead of using the
authoritative spool.slicer_filament_name ("Bambu PLA Silk").
Fix: the backend now saves the slot preset mapping in assign_spool()
after successful MQTT configuration, using slicer_filament_name as the
display name. This covers both frontend paths and ensures the correct
name is always stored.
X1C and X1 virtual printers used legacy SSDP model codes
(3DPrinter-X1-Carbon, 3DPrinter-X1) that BambuStudio doesn't
recognize, causing "incompatible printer preset" errors when
sending prints. Changed to the correct codes (BL-P001, BL-P002)
that real printers report via SSDP.
Also fixed proxy mode auto-inherit storing printer display names
(e.g. "X1C") instead of SSDP codes, by adding a resolution layer
that maps display names to model codes.
DB migration auto-converts existing VPs on startup.
Daily beta build tags (e.g. v0.2.3b1-daily.20260316) were not detected
as prereleases because parse_version() only checked the last
dot-separated segment for letters. The daily date suffix is purely
numeric, so it passed the stable release check. Now checks the entire
version string for prerelease markers.
- Sanitize project notes with DOMPurify before rendering via
dangerouslySetInnerHTML (ProjectDetailPage.tsx)
- Replace hand-rolled HTML sanitizer with DOMPurify in ProjectPageModal
to prevent attribute injection via crafted 3MF href values
- Block /api/v1/auth/setup when auth is already enabled to prevent
unauthenticated clients from disabling authentication remotely
