I have a South Bend Magnaturn CNC lathe that I want to get up and running. I have split off the single phase computer components and am running the 3 phase components from a rotary converter. I can get the fans to run, but nothing comes-up on the screen. I have tried a different monitor and it seems that I am not getting anything to the monitor. I can hold-in the magnetic contactor and get the blower and hydraulic pump to run. Does anyone know anything about these lathes? How about somebody that I can talk to? I don't want to have to pay BIG BUCKS for a service guy, but if I have to then I will. How about a retro-fit?
