Re: MaxNC Controller Question

Hi Scott,

Probably about 6 IPM, but that's with a 386/33. As I understand, your
drive is 4-phase also, are your motors 24v? Twin shaft is not such a
big thing, although I did get them on my new motors. I want to try some
encoders. For running the mill, the jog buttons and MDI work fine for
me.

P.S. There is also a MaxNC list, might be other users w/145's.
