I changed computers and now have a good pulse rate and line with very little spikes, but the motors still do not run. I have used the Gecko troubleshooting diagram and have come down to the "check controller timing G203V step input specs: min step '0' time = 0.5 uS min step '1' time =3 uS". Could someone explan this and how do you correct ifd it is not right. Thanks, Jimmy
