I am using inches and using longs 34 motors and I have checked connections several times. I did change to 50 percent, however it does appear to be faster when running the demo but it could be my imagination. I bought this as a kit and at time didn't know as much about it and as you see still don't know. Maybe it is the computer telling it what to do or maybe a differnent board would be the answer. I understand that without looking at the system its hard to diagnose. I am not giving up just have to rethink, reset, check and try again.
Thanks for everyone's help.
