Rich,
I'm almost through the manual, I'm up to Appendix A and so far it's very good, couple of things though, maybe for the samples on the arcs and circles it would be nice if numbers were provided to do the moves to, I wasn't really sure what numbers exactly to put in, I finally got it and it works great, also in the circle probing instructions you have teach a, b, c instead of touch a, b and c, just a typo.
I tried the 3 point circle with a 200X microscope mounted on my machine on a quarter and the accuracy of the dimensions was amazing,
I measured the quarter with a digital caliper and it read ~.9435, then I did the 3 point circle and it gave me a measurement of .944, wow !
The pics below are of two different quarters.
