To test you will need to :
type P<enter> then give position
The motors should move, if not check connexions.
Then you have to check that the endstop ae working:
If the result end with ',0', and the endstop is not activated, its good. (if it's not good, revese them in the config)
If the two endstops are at 0 when reset, the homing will be peformed. Homing is alway in the opposide way of the motor (-max angle)
