I think Plasma Cam has pretty good support. My machine has dual head oxy-accet & plasma. I wanted to fit a laser indicator to it for location aid. I just found out a week ago that the company, Pratical CNC is no longer in business. This machine I have has been in service for about 2 years w/o problems but now I have that thought in the back of my head you know? I guess most of the parts in these machines are pretty standard with exception of the software and brain.
