So here’s the question: which lenses and windows have you been cleaning per the instructions?
That statement makes me think you’ve only been cleaning the lid camera, which won’t affect cutting performance either way. It will help the system calibrate, give you a clearer view of the bed image in the app, and recognize QR codes better.
The laser is for all intents and purposes invisible but it’s taking a fairly long path before it shoots out of the head at the material.
There is a window hidden on the left side of the gantry, underneath the machine top (have to poke head in to see pretty much), a window on the left side of the head, then a mirror inside the head (beneath a removable top), and finally the lens on the bottom side of the head that has to be removed (with the lens removal tool) to be cleaned.
