It was the power supply first, then the tube also went bad. Still having the random no fire issues a year later. I have figured out it is the power dial that has a short in it. Its all suppose to be under warranty but bodor just wants me to disconnect it. Which I think is BS. I paid for an operational machine and it has been nothing but a headache. Oh and one of the rods that moves the gantry snapped like a twig. had to wait 3 weeks for a part for that as well. This machine has been down more than it has ran. I was going to sell these for this company, but now. No way. I am going to buy my next machine from DLM Lasers, Made in the USA with as many USA parts as possible and he will train you and teach you how to use the machine if you are new to lasers. He delivers and sets up. https://www.facebook.com/DLMLasers/?ref=br_rs&pnref=lhc
