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).
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
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.
Strip @mentions from changelog text in docker-publish-daily-beta.sh
so GitHub doesn't auto-generate a "Contributors" section in release
notes. Add --generate-notes=false for extra safety. Also add ports
2024-2026 (A1/P1S proprietary) to the docker-compose.yml bridge-mode
port mapping and update the install script comment.
- Add ports 6000 (file transfer) and 322 (RTSP camera) to Dockerfile
EXPOSE and docker-compose.yml bridge mode port mapping
- Update migration doc with new proxy mode port requirements
- Regenerate proxy-mode-diagram.png with all proxied ports
When running multiple virtual printers with different access codes on
separate bind IPs, FTP connections were always routed to the wrong VP.
Root cause: the iptables REDIRECT rule (990→9990) rewrites the
destination IP to the incoming interface's primary address. With Linux's
weak host model (arp_filter=0), packets for secondary IPs arrive on the
primary interface, and REDIRECT sends them all to the first VP's FTP
server. MQTT was unaffected because port 8883 had no redirect.
Fix: FTP server now binds directly to port 990 (standard implicit FTPS),
eliminating the iptables redirect entirely. Requires CAP_NET_BIND_SERVICE
(already set in the systemd service file and Docker image).
Also removed a global asyncio set_exception_handler() in the MQTT server
that was overwritten by each VP instance, causing spurious "Unhandled
exception in client_connected_cb" errors on startup.
Changes:
- FTP_PORT: 9990 → 990 (ftp_server.py)
- Removed set_exception_handler() from MQTT server
- Updated Dockerfile, docker-compose.yml port mappings
- Deprecated --redirect-990 in install script
- Updated wiki: removed iptables instructions for all platforms
- Added migration guide (docs/migration-vp-ftp-port.md)
- Added unit tests for port constant and no-global-state invariant
Multiple Virtual Printers:
- Each VP gets a dedicated bind IP with independent FTP, MQTT, SSDP, and Bind services
- New VirtualPrinter DB model, CRUD API (/api/virtual-printers), React UI
- VirtualPrinterList, VirtualPrinterCard, VirtualPrinterAddDialog components
- Per-instance TLS certificates (shared CA), 11 printer models, all 4 modes
- Auto-incremented serial suffixes, network interface override per VP
Dual Bind/Detect Ports (#445):
- Listen on both ports 3000 and 3002 for slicer bind/detect handshake
- Different BambuStudio/OrcaSlicer versions use different ports
- Applies to BindServer (server mode) and SlicerProxyManager (proxy mode)
- Updated Dockerfile, docker-compose.yml, firewall rules in wiki
Also:
- Rewrote VP test suite for new multi-instance architecture (75 tests)
- Rewritten "How it works" section with 3-step workflow explanation
- Updated all 5 locales (en, de, ja, fr, it)
- Updated wiki and website for multi-VP + dual ports
- New multi-VP screenshot
Recent BambuStudio/OrcaSlicer updates require a bind/detect handshake on
port 3000 before connecting via MQTT/FTP. Without this, slicers cannot
discover or connect to the virtual printer in any mode.
- Add BindServer for server modes (immediate/review/print_queue)
- Add TCPProxy for raw TCP forwarding (proxy mode)
- Update Dockerfile (EXPOSE 3000) and docker-compose.yml (bridge port)
- Add 10 new tests for BindServer protocol and integration
The timezone collected during docker-install.sh was being saved
to .env but docker-compose.yml had a hardcoded TZ=Europe/Berlin.
Changed to TZ=${TZ:-Europe/Berlin} to use .env value with fallback.
Enable Bambu Studio on a remote network to print through BamBuddy
acting as a TLS-terminating proxy for both MQTT and FTP connections.
- Add TLSProxy base class and FTPTLSProxy with PASV response rewriting,
EPSV→PASV translation, PROT P/C tracking, and one-shot data proxies
- Add SlicerProxyManager to coordinate per-slicer MQTT + FTP proxy pairs
- Support additional SAN IPs in certificate generation for proxy mode
- Broadcast SSDP on LAN B so slicers discover the proxy as a printer
- Narrow FTP passive port range to 50000-50100 with retry logic
- Expose proxy ports (8883, 9990, 50000-50100) in Dockerfile
- Document passive port range in docker-compose.yml
- Add user directive to docker-compose.yml using PUID/PGID env vars
- Allows container to run as host user, fixing permission issues with
bind-mounted volumes (e.g., ./virtual_printer)
- Add chmod 777 to /app/data and /app/logs in Dockerfile for non-root compatibility
- Usage: PUID=$(id -u) PGID=$(id -g) docker compose up -d
Note: Existing named volumes (bambuddy_logs, bambuddy_data) created by previous
root containers may need to be removed or have permissions fixed manually.
