I see you got a Conqueror Design and Engineering Limited base unit, is it the cnc2, cnc2x or cnc3.
I have found mine to be an OK unit saved all the hastle at the time, may have had a go at my own since I found this site but way back in 2005 there was so much conflicting advice I didnt know which way to go!
CDE also have a unit for controlling the plasma torch.
