Re: Bridgeport BOSS conversion

I'm using API CMD-260 drives (similar to the Gecko's). My
Bridgeport steppers were Sigma (rather than Superior) and it runs a
heck of a lot faster than 30 ips at 72 volts DC. Mine are direct
connected to the ball screw (maybe that makes a difference). I was
able to canabalize the NC controller power supply for the
transformer, caps and bridge to change the voltage.

Merry Xmas,
Jeff
