Hi Al, thanks for the reply. I will take another look at the wiring, my memory is toast.

I don' think I have the DC ground tied to the chasiss ground on the mill. Just about all the wires are twisted. I do not have any kind of additional ground wire connecting the PC chassis, just the existing in the cables from the controller card. I was a little nervous about doing that. But it can't hurt, right?

This was working fine for a while, just acted up again. I bet there is a loose ground someplace.
