Re: [CAD_CAM_EDM_DRO] Servo motor selection

Mr. Bordens:

After reading your note I got on the Grizzly website to look for the mill
you identified as G3012. They don't list a mill with this number. The reason
I am e-mailing you is that I am also interested in the purchase of a mill to
upgrade to CNC. I would be interested in what made your choice for this
model? Thanks for your reply. Ed Katz
