I have the combination of a 3018 Pro machine with a Lightburn S9 motherboard and Neje 30820 laser module.
Now the next problem occurs that the dimensions of objects/rectangles are not displayed correctly.
As an example, a rectangle of 200 x 200 mm is given with the dimensions 20 x 20 mm.
Does anyone have an idea what it could be?

If you have selected unusually large fonts on a small screen, some of the digits may not appear in the numeric boxes:
If that’s not it, then screenshots of the LightBurn layout showing the problem would be helpful:
If the actual laser-cut pattern has a different size than the LightBurn layout, then pictures of the results (including a metric scale) will be helpful.
Because you have a custom setup, the default Sculpfun configuration won’t work.
Have you configured the GRBL settings for the 3018 hardware?
In particular, the step/mm and maximum speeds for the axes will be completely different. Those settings account for the problems you’re having, but you must make other changes, too.
You should read through the entire Common GRBL Setups doc and also understand how GRBL configuration works.
