Does anyone have any idea what might have happened here?
The setting was 1000mm/60%. The surface is a coated MDF board. I know that the color white is not exactly the ideal background for a blue laser.
Nevertheless I wonder why only the corners of the grid were burned in and the lines are not visible.
It was supposed to be a grid, which I created with the grid array (10x10) function of Lightburn. It looks to me as if the laser ignites with 100% at the start of each cube and then continues with 60%.
What do you think?
