Wow, glad to be back the last 4 days sick sucked and then new years stuff.
So disconnected yellow wire and trouble still once again. So I noticed the V on thc was +/-3.5 
Used to be 1.5…said okay and turned thc off, guess what? It cut and finished the small pc.
So I just ordered a new dmm since I couldn’t find my other 3 or 4 and will diagnos thc, next week.
I will update other thread also, didn’t realize I had 2 going one, needless to say…there are 2 models of cnc ports on the razorweld 45, ONE IS 2 two prong, and then mine has a 4 prong and a 2 prong, if you have the 4 prong plug turned 90* trigger won’t be triggered…
On to thc checking, since it worked fine for 6 months…
Stay tuned to adventures from the goat shed…and no, smart–'z this will not have a brazzer logo
