General Mach Discussion / Re: Scale is off..

The problem was with the PC. The configuration is fine. I have a PC upstairs I have been uising for all the softeware testing. Saturday I got the motors installed on the CNC I built, and so I had to transfer everything to a different PC dedicated to the new CNC. A notebook actually. I knew the notebook would cause problems at some point, but based on what I had read I was expecting lock ups and errors of that type, not problems just running a stepper. I ran the driver test on the PC and on the notebook. While the test on the notebook said the pulse rate was steady, the graph indicated a serious problem and was actualy clipping at both ranges. I had planned to use a Smooth Stepper from the begining, but wanted to get the CNC running right with the parallel interface first to make sure any problems I had, I could isolate to the origianl configurations, or the Smooth Stepper. I went ahead and installed the SS and configured Mach3 for it and it's all running fine now. In fact, it's running much smoother and much faster than with the parallel driver and the full size PC.
Sorry about yelling "Wolf" but I'm new to this and didn't know what a well tunned stepper sounded like. I think with the notebook it was just getting a small fraction of the pulses and hence the apperance of a scaling issue.
Learning as I go....
