Warco VMC Turret Mill - CNC Conversion

It what way is it better? What stepper drive units are you using? I was looking at the 240v versions from Zapp automation?

I used them and no regrets, not cheap but you save a bundle on power supplies. Minimum current is 3.18A RMS 4.5 peak. I wired the coils in series because Gary said it would keep the heat down, even so. Any suds splash that lands on the motors boils off but the heat doesn't seem to be a problem. OTOH, do try and dump the heat in to the mill rather than on to the lead screws.
