    Hello cnczone members!
    I have an issue with my laser cnc 50 w chinese cutter.
    I don't have clear cut. The cutting line is not smooth. I attached a photo with the problem. Has another member this issue?
    Thank you!!Chinese laser 50W, 50x30cm - bad/good stuff, mods, problems etc.-30020421_10216514827293040_952559385_n-jpg

    Symptoms of that failure was the laser PSU was totally dead. No fan, no power LED, no laser

    What is your laser PSU doing in the failed state?
    Can you share with us what model Laser power supply you have?
    Have you got an ammeter installed?

    I have not put that many hours (maybe about 40) on my machine in the two years I have had it. As they come they are hobby grade, hence the hobby price. I'm sure with a better laser tube, power supply and a few tweaks like an ammeter they might do ok but I personally would not use this machine to run a business unless I had a garage full of them and some spares.

    I guess at two you have made a start

    I own 3 of these machines for that reason. I only get 9 months of use before I change the power supply and tube. I always replace both at the same time. This has extended the life of mine.
