Got my Ortur LM2Pro about 3 weeks ago, been running around a total of 10-15 hours since assembly.
My first cutout test was pretty much perfect a speed of 210 mm/s and 90% power, 3 passes on a 6mm plywood board.
Lately i’ve been getting severe burned edges when cutting and doing more passes, decided to run a new test, exact same type of wood and exact same settings. Results are as you can see in the images.
It doesn’t even cut through anymore with those settings. Even tried different focus lengths with no remarkable difference
I understand that this laser isn’t really meant for cutting, but this much of a difference on such short time doesn’t seem right to me.
Crossing fingers for help or solution
