I have cnc 3018 and I installed 40W laser from annoytools. I bought it from AliExpress.
The problem is that when I’m trying to cut wood ( 3mm plywood) is not cutting.
I managed to cut a small square with
100 mm/min for the speed
85 % laser power with 2 passes
But the next day I tried that one more time but it didn’t work.
So I kept trying till manage to cut wood again but with speed of 200 mm/min
10 passes with 0.2 mm ( Z step per pass ) I was enthusiastic and tried to cut another design with the same parameters but unfortunately that didn’t work at all so I went back to the old design but also it was not cutting
Have anyone faced such a problem?
