@alex-cr said in Laser issue - less "power" when moving in "X":
But something interesting is going on because now my original link does not link it to the 15W side but rather back to the NEJE store showing 10W output. Now I am really confused.
In the past, NEJE got lots of negative customer reviews, because they advertised their modules with 40W. They didn't lye, because that's the input power. Now they are rowing back and advertise it with output power. Because of the FAC lens, they could focus the beam even more, so they called it 15W optical power. The bashing never ended, so they started to call it what it is: 10W output power, but 15W optical power from higher density.

Rotating the laser showed that it can now cut while moving in X but not in Y.
I can only guess, that their fixed focus isn't adjusted well, so you are using a less optimal module height.
I've seen a simple test video where someone placed a piece of MDF at an angle and lasered along the slope. That way he could find the sweet spot of his module.
If I find the video, I'll post it here. Skip the unboxing and start watching at around 3:00 mins.
