Re: [CAD_CAM_EDM_DRO] which steppers to buy?

Hi John,

I understand what you are saying! I'd expect that you'd need something
like 300-400 oz/in (from what I've heard for mill/drills, and 3 in 1's,
but hay, If the motor mount fits, try it! I plan to try some old NEMA
#34 S/S 300 oz/in motors on my new RF-31 mill, with 3:1 drives, even
though their not really big enough! I will put on bigger steppers when
I can afford them! For now, I'll even leave the Acme lead screws!
