Config

• User config: ~/.config/bambu/config.json
• Project config: ./.bambu.json
• Precedence: flags > env > project config > user config

Access code

Get the printer access code from the device or Bambu Studio, then store it in a file:

mkdir -p ~/.config/bambu
printf "%s" "YOUR_ACCESS_CODE" > ~/.config/bambu/lab.code
chmod 600 ~/.config/bambu/lab.code

In Bambu Studio on macOS: open the Device view for your printer, open its settings, and look for "LAN Access" or "Access Code" (often shown alongside IP/serial details).

Env vars

• BAMBU_PROFILE
• BAMBU_IP
• BAMBU_SERIAL
• BAMBU_ACCESS_CODE_FILE
• BAMBU_TIMEOUT
• BAMBU_NO_CAMERA
• BAMBU_MQTT_PORT
• BAMBU_FTP_PORT
• BAMBU_CAMERA_PORT

Notes

• Printer must be reachable on ports 8883 (MQTT), 990 (FTPS), 6000 (camera).
• Avoid passing access codes via flags; use --access-code-file or --access-code-stdin.
