Cannot move out of 3d printer and printing bed

I am attempting to use laser and cnc but each time I go through the process for either I receive an error message stating that it is not recognised and that ants to accept 3d printing. This happens through luban but also when I try and use the snap maker hand held screen to calibrate laser or use cnc the bottom of the screen show the heat bed and wants to use 3d printing. The laser was working perfectly a couple of weeks ago. Any suggestions. I have tried to reset to factory settings but the issue is still there.

Do you remove the heated bed when you change workloads?
