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?

One pass. What does backlash mean? (I’m kind of new to this) Aligning the mirrors did stop it from happening again, but maybe that was accidental?
