I have an order on a Precision Matthews mill and need advice on how to wire up the conversion of the mill to CNC, using the PM ballscrew kit. My goal is to mill aluminum and mild steel.

By way of experience, I currently have an Avid CNC Router Parts with their turn-key electronics running Mach4. I put together the mechanics (8020 and motion system), but have bought the electronics already assembled in their industrial box. Have quite a bit of experience with using the router on plywood and sheet aluminum (which in reality only means I broke many bits). Then have upgraded to plasma motion (THC) myself. Also have experience with Fusion 360 and PlasmaCam.

What is the most streamlined way to run the mill on the same computer? What electronics boards and motor drives and motors to get? Am leaning towards NEMA 23 steppers unless advised otherwise. Am considering a Centroid Acorn but is there a reliable way to use Mach4 which I already have and like? Thank you kindly for any advice.
