I get the error ALARM:6 and the software won't let me do anything

Startup error. Reset during active startup cycle.

Alarm 6 Homing fail
Homing fail. The active homing cycle was reset.

Are you using the correct Power adapter, seems your controller is resetting or failing mid homing cycle.

What Laser, brand/model?
