On a Shoptask you need the largest motor on the Z axis. The 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. I am sure that there are ways to get the machine to pull the table,
but it just has not happened in the limited amount of manual work I have
done. With steppers there is considerable resistance to turning the cranks
and when I had steppers on the machine it was actually a PITA to do anything
by hand. Now with the servos the machine is easier to use manually and I
still have not had it grab the work and spin the screw. Makes me wonder how
much of it is armchair musing and how much is actual experience??

What is typically the preference for which axes get the higher torque
motors? My understanding is that its usually the Z-axis, but because
of the quill feed configuration of the mill/drill, it won't require a
high torque motor. Is the shoptask similar if I don't convert it to
ballscrew? If I put one of the triple stacks on the Z of the
Shoptask, then I'll have to mix up one of the machines X-Y. Would
the X feed on the Shoptask be the best choice for the larger motor
because its also the lathe (Z) direction?
Thanks!
