The spool detection only checked tray_uuid and tag_uid, but some Bambu Lab
spools have RFID read issues causing these to be missing while still having
valid tray_info_idx (Bambu filament preset ID like "GFA00").
Backend changes (backend/app/services/spoolman.py):
- Add tray_info_idx to AMSTray dataclass
- Parse tray_info_idx from raw MQTT data in parse_ams_tray()
- Check tray_info_idx first in is_bambu_lab_spool() - most reliable indicator
- Bambu Lab presets start with "GF" (GFA00, GFB00, GFL00, etc.)
- Fall back to tray_uuid then tag_uid for unique spool identification
- Add warning when Bambu spool detected but no unique ID for Spoolman
Backend changes (backend/app/api/routes/spoolman.py):
- Update /sync/{printer_id} and /sync-all to pass tray_info_idx
- Guard against empty spool_tag when adding to tracking set
Frontend changes (frontend/src/pages/PrintersPage.tsx):
- Add isBambuLabSpool() helper with same detection logic as backend
- Update all 4 vendor detection locations in AMS cards to use new helper
Detection priority (same on frontend and backend):
1. tray_info_idx starts with "GF" (Bambu preset ID)
2. tray_uuid is valid 32-char hex (non-zero)
3. tag_uid is valid 16-char hex (non-zero)

🚀 Quick Start
Requirements
- Python 3.10+ (3.11/3.12 recommended)
- Bambu Lab printer with Developer Mode enabled (see below)
- 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.

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
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
Reverse Proxy (Nginx):
server {
listen 443 ssl http2;
server_name bambuddy.yourdomain.com;
ssl_certificate /path/to/cert.pem;
ssl_certificate_key /path/to/key.pem;
location / {
proxy_pass http://localhost:8000;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_read_timeout 86400;
}
}
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 can discover printers via subnet scanning - enter your network range (e.g.,192.168.1.0/24) in the Add Printer dialog.
Manual Installation
# Clone and setup
git clone https://github.com/maziggy/bambuddy.git
cd bambuddy
python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt
# Run
uvicorn backend.app.main:app --host 0.0.0.0 --port 8000
Open http://localhost:8000 and add your printer!

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.
