Ok, I got the scope out and looked at the wave form on one of my axis (at the printer port) when it was moving. I first tried it with Kcam running to see what the signal should look like. I saw a nice 50% duty cycle waveform with about a 10mS period. I than switched over to Mach 3. With the axis moving in Mach 3 I see a very low duty cycle waveform. The on time is around 5uS and seemed a bit erratic my scope was having a hard time triggering on it. So it looks like my Mach 3 setup is putting out a waveform that is way too fast for my controller or motors to respond to , or the duty cycle (on time) is to short. Any clues to what is wrong?
Thanks
