First post here- usually can solve my problems at the Candcnc forum. Have had a Candcnc Wndows setup with a Hypertherm 65 for about 4 years. Recently switched from XP to Win7- having some new problems that eventually sent me here after we narrowed down the problem to possibly being in the actual plasma cutter itself. When I test the voltage at the Candcnc PWM unit (from the plasma divided arc signal board), I get a voltage of .26 volts, which is low by a factor of 10. Should be somewhere around 3 volts, according to the Candcnc moderator. The jumper on the PWM is set at 50:1, and a look inside the Hypertherm shows the dip switch set at 50:1. Any ideas on what's going on? I've got electrical continuity from the PWM all the way back to the small voltage divider card so that seems to rule out any bad/intermittent contact. What I can do to get back up and running?
