I’m new here - hoping you can help. I have a blue china 50w laser. I’ve had it a couple of weeks, and I’ve been testing/setting it up with good results so far. The other night though, I started getting a “wobble” when I cut diagonally. Horizontal and vertical lines are straight. Previously, I did not have this issue. I have attached a test cut photo - it improves slightly when the speed is slowed down. I’ve also attached a photo of a fractal tree I did the other day with no wobble issues. My first thought was belt tension, or is it possible that the laser tube loosened up and is vibrating a little bit?
Thanks for any tips!
