On my first powerup of the system I am testing the motors with the Jog from AR2. But J1 jog does nothing, J2 jog controls J1 motor, J3 jog controls J2 motor etc etc up to J6 jog controls J5 motor. Its as if they are all displaced by 1. All the motors I can control will go forwards and backwards as they should. I have checked all my wiring to the best of my ability. Any ideas?
Why you're using Chain Sprocket transmission technique instead of timing belt and pulley in J3? Any specific reason.
