I believe you have to read the following docs:

Engraving Shifted Relative To Cut Lines - LightBurn Documentation

Layers Shift When Cutting Multiple Objects - LightBurn Documentation

.
Also you can run the file of this tread to confirm your laser mechanics.

Burn Offset LighutBurn 1.7.03

This test pattern helps identify mechanical problems: GrundTest.lbrn2 Scale it to fit the platform and run it as fast as it will go in Line mode with optimizations turned off and power set to mark a sheet of cardboard. Any differences from the design will be informative. Upload good photos of the result so we can look over your shoulder.
