Derrick-
It's a long story, but I have gutted and replaced the entire set of controls with newer electronics, running Mach3. All of the new electronics are 110VAC single phase. I am running the spindle motor with a VFD, and that is single phase in three phase out. I have not yet connected the VFD to run under Mach3 control, however, that is slated for the next major upgrade - Mach3 as the interface software, and a 4 axis Galil board as the motor controllers. I have brushless DC motors, cables and drives along with an entire Galil 4 axis set up. I am just starting to bench test this setup, as I want to keep my machine fully functional for as long as possible before converting to the new setup.
I had originally run the machine with the original electronics on a cheap phase converter and a surplus 5 HP 3 phase motor. It was noisy, consumed power when the spindle wasn't even running, and the legs voltages varied widely. These facts may have hasened the death of the original computer, and the replacement one that I put in. I had wanted to upgrade the controls since the first day I bought the machine, so I really didn't mind that the original motherboard fried. Let me know if you want some spare circuit boards or power supply - they are taking up valuable room in my small shop where I could store other junk!
