RE: [CAD_CAM_EDM_DRO] Stepper size?

A Sherline sized mill seems to need something in the 125 - 150 in/oz range
for decent performance. My Shoptask was functional, but far from spectacular
with 250 in/oz motors and was pretty decent with 550 in/oz units. My guess
is that 125 would not be adequate for your task.
