    So I was cutting some Romark 1/8" substrate unit signs for an apartment complex and decided to turn the laser to 100% power because I've been having issues of it not cutting all the way through the material and having to do multiple runs on lower power (40%). I noticed a small fire on top of the laser and immediately shut off the machine. After some cleaning with q tips it seems to be some kind of plastic or rubber gasket which I removed because it was melted. The laser still runs fine apparently but I was wondering how necessary this piece is and if it's safe to run the laser while I order the part to replace it. Thanks!

    If it's the small rubber gasket around the final focusing lens...yes you can remove it, I don't use them, they melt and catch on fire if you don't clean the lens as you should.
    I'm wondering why your lens is getting so hot? It needs to be clean, but I'm the worst for giving cleaning advice as my rubber gaskets either melt or catch on fire..
