    Re: sainsmart-1-axis-cnc-servo-stepper-motor-motion-programmable-controller

    I have had it running for a few day BUTTT..... as I move only 104 steps to the new position I have an erratic output. I use shielded twist cable and have grounded the shielding to a common ground. I even make a full rotation (10,0104 and get the same result. You would think it would be an accumulative amount of error. As I ran it many many times I detected a difference sound at the same point of the rotation.

    Maybe some kind of a mechanical bind at one point?
