So I've been fighting issues with this cutter for weeks now. I suddenly lost most of my power earlier today for no reason. I kept slowing the cut down but the cuts kept getting worse. So I ran off to get my other tube that wasn't working right and I've had 2 different tubes in there now and both seem to be doing the same thing. They kinda stutter a bit when it first fires on. Seems to settle down after it warms up. Sorta like a fluorescent bulb will when they get old. Granted I suspect both tubes are bad but could this be caused by the power supply being too high a voltage? I bout a 40/60W power supply in hopes of upgrading eventually. Also of note is the fact that I have lost a lot of current. Like 10 Amps. I'm going to ramp up the input voltage a bit more and see if I can get it to 16ma again. Both tubes had about the same amps. I was testing my connections and just redid both of them before I swapped tubes.
