Sherline mode worked!! I looked at the waveform and it it is still a low duty cycle, about 10% but seems to work fine with my controller. It is a very stable frequency now the scope triggers well on it. Were is the pulse width setting? I did not find that. Thanks for all the help. I'll be making chips in no time.

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

The DRO does not move when i use the arrows but, i think that is because i am using a laptop that douse not have the number keypad. The DRO does move when I hit tab and click on the jog arrows with the mouse. I will check out the outputs with my scope later today and see what is going on at the port. Thanks

Hello all,
   I just loaded up Mach 3 to give it a try with my mill and have had no luck with getting my motors to move. I watched the getting started and troubleshooting video to check for the common errors. I have been using kCam so I have the port address, port number, and pins correct. I have the E Stop set so it stops flashing at me when I hit reset. I made sure all the check boxes on the first tab in port setup were correct. I tried toggling the active low + high for the step pins. I ran the driver test .exe and it everything looked good. There are no leds lit on the diagnostics tab. What could I be missing?  Thanks for any help
