Full power lase

I’m still going for full laser performance

It looks like you need to enable overscan, and probably set it higher than the default. The dark sides on those squares will improve.

can you tell me which settings to edit? well thank you

Double click an entry in the cut layer list at the top right. There’s a toggle called “Overscanning” - Enable that, and try 5% to start. You may need as high as 20%. https://github.com/LightBurnSoftware/Documentation/blob/master/Operations.md#scan
