How to Fix Module Switching Problems (3D Print / CNC / Laser)
Step-by-step fix for module switching problems (3d print / cnc / laser) on Bambu Lab printers including X1C, H2D, P1S, and A1.
How do I fix module switching problems (3d print / cnc / laser)?
- 1
Power off completely before swapping modules. Hot-swapping is not supported and can damage the connector pins or confuse the firmware.
- 2
After attaching a module: verify the connection is fully seated — you should hear/feel a click. Run the module self-test from the touchscreen.
- 3
Clean the module connector pins with IPA and compressed air if the printer fails to detect a module. Dust from CNC operations often contaminates the contacts.
Pro tip: Module switching is a strength of the Artisan. Keep connectors clean for reliable swaps between 3D printing, CNC, and laser.
