Re: I am Lookig for stepper??

youser !

looking at the math, it is a pretty sure bet that the stepper won't
miss a step. But it would tear apart my bitty drill press.
think of all that on a 3/64th drill........

Now I am confidant that the NEMA 23 I have (5.4V 1.5A) will drive my
drill press with little effort.

Thanks for this thread, it gave me some frame of reference for my
project.
