THC Setting Issue?

[tommylight]

I have 4 of Proma THC and been using them for over 2 months so here is where i am at:
3mm mild steel light bent at 2-3 cm per feet i can cut at 5500mm/min at 60A all day long, mostly use it at 3000-3600mm/min at 30A so i do not bother to be near the machine at all
2mm mild steel cut mostly @4200mm/min @30A
Back to your problem: you did not mention the delay--> lower it on the THC so you get faster response from it, and if this does not help, you might need to change the computer or do a fresh install.
B.T.W i use linux exlusively but i had a winXP/Mach3 setup for a client that does production work with it on a 3.5mX2m work envelope with a Hypertherm MAX100.
Regards,
Tom
