Brand new here, Im a journeyman machinist, work with industrial cnc equipment and have done one cnc build on a purpose specific machine using Mach3.

I’ve bought a new knee mill (microcut pbm-4evs) with the intent of converting it to cnc control.

I’m sure this had been done a million times but I’ve come up empty trying to lurk... links are welcome!

Ok so this machine is a manual knee mill, box ways, 50” table, 5ph 3ph motor and nmtb40 spindle.

I’ll be getting ground ball screws (X,Y) and plan on ~1kw dmm servo motors (X,Y,Z with Z running the lead screw on the table) I also intend to make a 4th rotary axis using a 1.6kw dmm servo and brake.
I am familiar with mach3 with ess. I’m comfortable using cad/cam and gcode editing so I’m not overly hungry for conversation programming. This is however, a “substantial” , non-hobby, build and I dont want to short change myself where the controller is concerned. I’ve read a fair bit about centroid as well but am looking for suggestions
