Has anyone here got a cnc table running?

i've just built a small one and ordered a new cutter to fit onto it, due to budget, i couldn't get a non-HF start torch but the one I have coming has a socket for CNC triggering so I presumed it will be ok.

since ordering I have read nothing but bad stories of how HF start plasma cutters wreck pc's and cause all manner of control issues.

i have taken care in building my table to ensure no low level signals are taken outside the control cabinet but have not used screened cable on the stepper motors as I presumed the high current/voltage would stop rf pickup problems there.

I have also got a hand control pendant but apparently they can be a nightmare for interference too.!

this is doing my head in now, has anyone got a CNC table running on an HF start plasma torch and PC????
