Re: Grizzly mini mills

Hi Paul,

I also have a Grizzly mini-mill. I'm very interested in your CNC
conversion. Can you offer any details? Are you going to use the
standard Z-axis or build a leadscrew for it? What size motors are
you using? Servos or steppers? Which driver card? Any pictures? Are
you going to go with direct drive or use gears/pullys? What do you
think the cost will be?

Sorry for all the questions, but just thinking about this gets me
excited. I really want to do this to my mill also.

Please keep us informed.

Thanks!
