Are the stepper motors on x and y axis suppose to be hot after running for approximately 30 min. I can touch them but they are hot.

If your motors are hot to the touch, this is normal. Current is being drawn by the motor coils as the motor moves and as the motor stays at a position. If the motor is not using the current in the coils to move (holding it's position), the energy will be translated as heat (rather than motion, sound or light). Even while moving, some of the energy will be lost as heat. Remember that energy cannot be created nor destroyed. Additional Information: Additional Information: Additional Information:
