Anyone ever get a Primeweld 50A to work on a DIY CNC Plasma Table without the EMI causing unexpected stepper movement? I added many countermeasures which made big improvements, but not 100% gone. NC micro switch's w/sheilded cable, dedicated ground rod, seperate chasis grounding for everything, ferrite chokes everywhere.............monitor goes blank but pc and g code still run with the torch about a foot away. once i mount the torch head in the Zaxis holder, intermetent movements occur when i fire the trigger...................giving up on plasma for now. Really wan't to blame it on this cheap plasm torch. Had troubles with EVERLAST so I returned it. Can't afford a Hypertherm. Any input would be appreciated.

Anyone ever use Eathtek 400w spindle motor?
