How to Enable Developer Mode on Your Bambu Lab Printer
-
Bambuddy requires Developer Mode to communicate directly with your printer over the local network, bypassing Bambu Cloud.
Why Developer Mode?
By default, Bambu Lab printers route everything through Bambu Cloud. Developer Mode enables local MQTT/FTP access, which Bambuddy uses for:
- Real-time status monitoring
- Sending print jobs directly
- Camera streaming
- Printer control (pause, resume, stop)
How to Enable It
- On your printer's touchscreen, go to Settings
- Navigate to Network or General (varies by model)
- Find Developer Mode or LAN Only Mode
- Enable it
- Note the Access Code displayed — you'll need this in Bambuddy
Also Required: Store Sent Files on External Storage
In Bambu Studio or OrcaSlicer:
- Go to your printer settings
- Enable "Store sent files on external storage"
This ensures 3MF files are saved to the printer's SD card, which Bambuddy archives automatically.
Important Notes
- Developer Mode works alongside Cloud connectivity — you don't lose cloud features
- The Access Code changes if you reset it on the printer
- Your printer and Bambuddy server must be on the same local network
Once enabled, add your printer in Bambuddy: Settings > Printers > Add Printer — enter the IP address and access code.
