Re: [CAD_CAM_EDM_DRO] Re: Converting Bridgeport I to PC controls

John & Greg,
Thanks for the response, and especially the link telling me
exactly how to rewire the motor for 240V. You guys are the reason I monitor
this group. You can never tell where your help is coming from, whether it's
"across the pond", or "way across the pond", it's much appreciated. By the
time I acquire the Bridgeport, I will have done all the R&D to make it work.
