Well I found the problem, although I'm not sure why it was acting exactly like it did.  I got to thinking that I was still running with the default parameters in the drives and I started looking through them to see if I could change anything that would help.  The first one I changed fixed the problem, it was the position loop gain.  The range was 0-200 and the default was 40.  I kept moving it up and things kept getting better.  I maxed it out and didn't see anything detrimental to leaving it there and it got me within .002 mm everytime. 

Weird that it showed up almost exclusively in one direction only, but there's no denying that it has fixed the problem.

Thanks to everyone for your help.

Regards,

Bob
