Hello

I'm in the process of CNC conversion of an Optimill MH25V mill, and would appreciate much to have your opinion about the following
I have so far decided to use the following components:

Nema 34 8Nm closed loop with associated drivers
2005 ballscrew on all axes with direct drive 1:1.
Still need to figure out the following:
Should I supply the drivers with AC24~70V or DC30~100V
Which controller (breakoutboard) should I use? Must be able to handle 5 axis and for Mach 4.
What do you think about my planned stepper size of this machine ?
