I have resolved my issues. I have, after much hand wringing and woe be tie. got an accuracy of, ta ta,  0.0013 . I'd like to thank you all for your help and direction. I am very excited and raring to go. Thanks again guys.

I don't want to pour cold water over your excitement, but if you are referring to the steps per unit (as in your old post), then unless your steps are very highly geared, you should get better than 1.3 thou.

As a matter of interest, what is you number of steps per thou. Mine, for example is 60,000 per inch, giving me a resolution better than 0.1 of a thou. Steps per inch is a fixed number which can be calculated, and not open to adjustment.
