Turns out a misaligned mirror made the laser hit the lens in a weird way, and then bouncing off something on the way out to produce this double line. Probably. What kind of strange troubleshooting have you done and what was the reason/fix?

    Could it be hitting the nozzle? That would be a very minor misalignment so it might be hard to notice

      Could be. Is there an easy way to test that? For the mirrors we had pieces of paper to see where the laser hit.

        Can you take the nozzle off for a quick test? Mine unscrews for cleaning, not sure if they all do though

          I could, but it’s a community laser cutter, so I’m a little reluctant to take things apart now that it works again. If the same thing happens again, I will try that for sure though!

            Oh followup question!

            Do the double lines only happen in specific areas of the cutting bed?

            I was getting weak cuts in the lower right of my machine due to some misalignment. Presumably because that’s the position where the mirrors are farthest apart

              I didn’t do enough tests, but it appeared more or less in every part of the bed. The guy who is an expert on this particular machine came and aligned the mirrors so it works now. He did say that the back mirror was most misaligned, and that that should really not be possible or something like that.

                Yeah that is pretty weird. The rear mirror is fixed to the body of the machine, it’s usually the front mirror that rides on the gantry that gets misaligned “naturally”

                Maybe someone smacked it on accident…somehow lol

            Ooooh yeah, not quite your place to be fuckin with it haha

            The workshop manager (or whoever is in charge) hasn’t tried to fix it?
