Re: [CAD_CAM_EDM_DRO] Power for Bridgeport series 1 vert mill

Hi Paul,
I'm running my Bridgy on a phase converter but realize that the only thing
that requires the 3phase is the motor. Iwould like confirm the transformer
is wired up from single phase only for the control when I get some time so
that I can move the axis etc without that noisy converter running when I
don't need it. I don't want to try it without some research first.
My question is this, would you mind taking a picture of your transformer
connections, mine aren't marked except with numbers, and I don't have a
schematic.
I have a Bridegport Series I CNC
Thanks
Brad
