Received my 10w laser module today. Shining it on the wall with the lightburn fire button, the beam is square. However, when having ir operate at low speed and power, I shined it at the wall and the beam is rectangular and fuzzy. The direction that would be “x” seemed ok. The direction that would be the “y” was longer than the “x” and appeared fuzzy as if two over lapping images. Could this be an incorrect setting of the mirror inside the module?

Having the same issue with the beam shape on my unit, did NEJE has solved the problem for you?
