Thanks Craig, the machine is complete and was running when removed but had some fault with the Z, that`s all I know, I have not put power to it.
It has siemens servo boards and motors, I never thought of keeping the original drives, might be a possibility
The thing that worries me about the spindle drive is it has a ton of wires connected to it, its a huge unit, not simple connections like a VFD, I have no idea why it has so many terminals

I have tried to google for a manual but have had no luck so far its a KTK 6P4Q7-5MTD and has a FXM5 field controller wired to it as well
I have looked at the PMDX-424 BOB, reading the spec it appears this board has a device similar to a smooth stepper built into it, and its designed to run on Mach4
The Lua programming is really daunting though as I have zero programming skills
