    Ed,

    Don't worry, I've adjusted the mirror alignment twice and it seems harder than it is. Just allow an hour or two for it.

    1 thing that helped me align my laser was to cut some 3/4 circles from poster paper. I put these over my lens. They showed where the beam was hitting real good.

    When I change my Universal tube I was finished in about 15 minutes. No other adjusments necessary.

  5. My tube also does not fire up all the time, I presume its something electrical somwhere, I just press reset and start again and after a few times it decides to go. When the laser was new it would stop engraving halfway through a job, the beam just stopped firing, no one solved that problem, but it hs not happened for a while.

    From here, it sounds like one possibility is the cover interlock switch is intermittent. If it's an inductive switch, maybe the magnet is too far from the switch. If it's a mechanical switch, maybe a connection loosened with all the travelling.

    I see this is a old thread, but I am in need of desperate help. I have a 40Watt Chinese laser. We have owned this for about 5 years and built a somewhat successful engraving business. My husband started it and I took it over 2 years ago. We usually have to replace the tube and power supply once a year. I have a new power supply and a fairly new tube. The machine is not firing. I see a beam in the tube, but nothing is coming out. My husband is usually the one that fixes any issues, but he is working 14 hours shifts right now. I have no idea how to fix this or what the issue could be? HELP!!

    you see a beam in the tube so the laser is firing,check the end of the tube for obstructions, check all mirrors for cracks, dirt what ever, Check lens and lens tube for cracks of obstructions

    I would put thermal paper between the tube and first mirror, to see if you have any output. If not, you likely have a bad tube. If you have a nice circular mark, you can work your way around the alignment process.
