Re: [CAD_CAM_EDM_DRO] Re: Rong Fu RF 45 vs RF 31 CNC - Help!

Hi Joel,

Nice clean CNC conversion! What are the oz/in of the steppers, and the
gear ratio of the pulleys? I think the RF-30 may be smaller then the
RF-31?

You don't mention ballscrews. That can add a LOT of cost! Encourages
me to get my RF-31 mill CNC'd. I have 300 oz/in steppers, which by your
pix look like they'd be able to do it.

P.S. You are indeed lucky to find those steppers and their drivers in
the dumpster!
