Watching your progress/design. I understand the thought behind turning rough on the lathe, but can you generate gcode that takes advantage of that? I'm just curious if you'd be cutting a lot of air if you were doing, for instance, a vase and you rough turned a vase shape. Or would you just be doing a simple cylinder on the lathe?

If my aged memory serves me correctly that means the tail stock is either too high, or too low.
I programmed a 2.00 dia cylinder. I am getting 2.05 on the headstock end and 2.02 on the tailstock end. I zeroed the bit to the top of the tailstock (the only flat surface I have, none on the headstock). The overall size discrepancy could be because I am not truly set to zero on the centerline of the spindle (eyeballed the Z zero). Taper is a different story.
Soooo, what I am going to do is ship the tailstock up to see if I make the problem worse or better. About .015 (three sheets of paper) should do it.
