Re: Shopbot, Rack and Pinion, Ball Screw, Acme precision screw?

Uh, duh. Re-read your post and saw "geared stepper motor." My bad.
Do you know where to get the geared stepper? I am trying to price
building my own compared to buying a shopbot. I would probably be
happier with my own in the long run. Also, how big of a lead screw
should you get if you don't use ball or rack and pinion?

Sorry to ask you all of my questions.
