requirements for X & Y are pretty much the same. You hear all the yak
about not being able to machine manually when you have ball screws. I
have ballscrews on my Shoptask and it machines manually just fine...

Tim,
I'm sure your right. When I looked at CNC'ing a lathe I was advised
by a ballscrew manufacturer to select low threads per inch if I
wanted to be able to use the lathe under manual operation. Its seems
pretty obvious is a leadsrews pitch was 1 turn/inch it would be hard
to hold. With 10 turns per inch it won't move.

My Tree mill came equipped with handles and 5tpi ballscrews and was
meant to be used either manual (learn and replay) or CNC. It doesn't
move on its own. Ditto on the Z axis.
