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

📣 Contributors Wanted — Help Shape Bambuddy
Bambuddy is a community-driven project and I'm actively looking for contributors — especially for two areas I can't cover alone:
- 📝 Documentation writers — help improve the wiki, guides, and feature docs so new users have a smooth onboarding
- ⚙️ Discourse admin — our Discourse forum is now live at forum.bambuddy.cool but still needs to be configured, themed, and tuned (categories, permissions, SSO, email, plugins, backups). If you know Discourse or want to dig in, I'd love your help.
- 💬 Forum moderators — help welcome newcomers, answer questions, and keep discussions healthy on the new forum
You don't need to be a developer for the docs or moderator roles. If you enjoy writing, helping others, or keeping a community friendly, you're exactly who we're looking for.
Get in touch:
- 🗣️ Forum — chats, longer discussions, guides, and community Q&A
- 💬 Discord — fastest way to chat
- 🐙 GitHub Discussions — open a thread

🌐 NEW: Remote Printing with Proxy Mode
Print from anywhere in the world — Bambuddy's new Proxy Mode acts as a secure relay between your slicer and printer:
- 🔒 End-to-end TLS encryption — FTP, file transfer, and camera are transparently proxied with the printer's real TLS certificate
- 🛡️ Optional Tailscale integration — per-VP toggle + Docker socket mount brings Bambuddy into your tailnet, so virtual printers are reachable from any tailnet device over a private WireGuard tunnel without port forwarding (setup). Bambuddy's self-signed CA import is still required for the slicer side because both Bambu Studio and OrcaSlicer only accept IP addresses in the Add Printer dialog — the Tailscale benefit here is the tunnel, not cert-import elimination.
- 🌍 No cloud dependency — Direct connection through your own Bambuddy server
- 🔑 Uses printer's access code — No additional credentials needed
- ⚡ Full-speed printing — Transparent TCP proxy, only MQTT is decrypted for IP rewriting
Perfect for remote print farms, traveling makers, or accessing your home printer from work.
Why Bambuddy?
- Own your data — All print history stored locally, no cloud dependency
- Works offline — Uses Developer Mode for direct printer control via local network
- Full automation — Schedule prints, auto power-off, get notified when done
- Multi-printer support — Manage your entire print farm from one interface

Virtual printer appears in Bambu Studio/Orca Slicer
🚀 Quick Start
Requirements
- Python 3.10+ (3.11/3.12 recommended)
- Bambu Lab printer with Developer Mode enabled (see below)
- "Store sent files on external storage" enabled in Bambu Studio/OrcaSlicer
- Same local network as printer
Installation
Docker (Recommended)
Option A: Pre-built image (fastest)
mkdir bambuddy && cd bambuddy
curl -O https://raw.githubusercontent.com/maziggy/bambuddy/main/docker-compose.yml
docker compose up -d
Option B: Build from source
git clone https://github.com/maziggy/bambuddy.git
cd bambuddy
docker compose up -d --build
Open http://localhost:8000 in your browser.
Multi-architecture support: Pre-built images are available for
linux/amd64andlinux/arm64(Raspberry Pi 4/5).
macOS/Windows users: Docker Desktop doesn't support
network_mode: host. Edit docker-compose.yml: comment outnetwork_mode: hostand uncomment theports:section. Printer discovery won't work - add printers manually by IP.
Linux users: If you get "permission denied" errors, either prefix commands with
sudo(e.g.,sudo docker compose up -d) or add your user to the docker group.

Updating:
# Pre-built image: just pull the latest
docker compose pull && docker compose up -d
# From source: rebuild after pulling changes
cd bambuddy && git pull && docker compose up -d --build
Daily Beta Builds:
Beta builds with the latest fixes are pushed regularly to the same beta version tag:
# Pull the current beta
docker pull ghcr.io/maziggy/bambuddy:0.2.2b1
# or from Docker Hub
docker pull maziggy/bambuddy:0.2.2b1
Use Watchtower to automatically update when new daily builds are pushed.
Note: Beta builds use version tags like
0.2.2b1— they are never tagged aslatest. Your stable installation won't auto-update to a beta unless you explicitly pull a beta tag.
Useful Commands:
# View logs
docker compose logs -f
# Stop/Start
docker compose down
docker compose up -d
# Shell access
docker compose exec bambuddy /bin/bash
Custom Port:
ports:
- "3000:8000" # Access on port 3000

Note: WebSocket support is required for real-time printer updates.
Network Mode Host (required for printer discovery and camera streaming):
services:
bambuddy:
build: .
network_mode: host
Note: Docker's default bridge networking cannot receive SSDP multicast packets for automatic printer discovery. When using
network_mode: host, Bambuddy auto-detects your network subnet and can discover printers via subnet scanning in the Add Printer dialog.

Enabling Developer Mode
Developer Mode allows third-party software like Bambuddy to control your printer over the local network.
- On printer: Settings → Network → LAN Only Mode → Enable
- Enable Developer Mode (appears after LAN Only Mode is enabled)
- Note the Access Code displayed
- Find IP address in network settings
- Find Serial Number in device info
Note: Developer Mode disables cloud features but provides full local control. Standard LAN Mode (without Developer Mode) only allows read-only monitoring.
Slicer Settings
In Bambu Studio or OrcaSlicer, enable "Store sent files on external storage" so that print files (3MF) are saved to the printer's SD card. Bambuddy needs these files to extract thumbnails and 3D model previews.
- Open Bambu Studio or OrcaSlicer
- Go to the Device tab for your printer
- In Print Options, enable Store Sent Files on External Storage
