I use the latest Lightburn 9.0.2 with a chinese laser 60x90 (MKS controller). I wanted to make a edge lit plate and used some engraving on acrylic. As you can see on the picture i see extra ‘lines’ in the engraving, every ~6mm you see a horizontal line (I cut it rotated 90 degrees ) .
I engraved before on wood this was not visable.
Lasersettings I used : speed 200/ power 20% (80W laser)
What is causing this lines? Hardware or software? What could i do to remove these lines.
If you need extra information let me know.
