Torch height control for Mach2?

[unns_boy]

Hi, I come across an article describing a torch height control circuit for Mach2 designed by Tom Caudle. Has anybody tried this circuit on Mach3 before? Does any modification need to be done in order to work with Mach3? By the way, I am using a Hypertherm 1250, does this circuit works with Hypertherm machine? Yip
