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?
Question
Why you're using Chain Sprocket transmission technique instead of timing belt and pulley in J3? Any specific reason.
Problem solved!
After close examination of some pictures of the wiring of the motor drivers to the Arduino shield, it appeared that my wiring was 2 positions displaced. After further checking I rewired so that instead of using MARKED pins 2 to 13 I used MARKED pins 0 to 11. After that all motors responded correctly. So I assume that the shield I purchased had incorrect marking. Buyer beware!
thank you for the follow up. I apologize for the late reply.
