Please test the solution @Ran offers here,
With LightBurn running and your laser engraver connected…
Click the Laser Tools button along the top row.
When the pop-up menu appears, click the Additional Settings tab on the right.
Before you push the Read From Controller button, please capture the screen that you’re seeing, so we can compare a before and after shot to see what changed. These are simulation settings and shouldn’t be connected to what we’re seeing.
Again, If you haven’t attempted this fix yet, please take the screenshot. (instructions below)
Press the Read From Controller button.
Take one more screenshot and drag the two images into a reply here.
Does the fix above also work for your laser engraver?
