Re: CNC retrofit using Bridgeport Power Supply?

Thanks, Tim.

I've rewired the transformer, pulled out the reactors to make
a linear power supply, ripped out the controllers and logic
boards and now have a nice 56VDC for the Geckos.

The only casualty was one rectifier (which was easily replaced
from the obsolete 56V reference power supply).

I wonder how many folks kept the Bridgeport power supply
instead of replacing it.
