  1. Hi Rodne
    I am wandering if you can help me. I have a problem with lens on my K40 Chinese laser. We only engraved with it for maybe 1hr but the lens at the back has a bad mark on it, like a chip in the middle of it. I'm wanting to know why it happened and how to stop it from happening again? Also are cheap Chinese lenses any good?
    Thanks Maria
