Tom,
Thanks for the reply. I was looking at the Microkinetics Package. It does
have a provision for encoder feed back. I realize there are two things we are
looking at. One would be lost steps, the other is location error feed back.
If I simply put encoders on my Acme lead screws, I could only keep track of
steps but not error. This is where I was wondering if adding spars would be a
cheaper and/or easier way of accurately positioning the work rather than
ballscrews. I have come to the conclusion that I am barking up the wrong
tree and need to get the ballscrews first. Peter
