Can anybody tell me what’s causing these offsets?
Is there a way to compensate in Lightburn?
could it be a issue in my machine settings?

Thanks for your help!
Looks like backlash.
Check that the pinion gears are properly secured to the stepper shaft for both X and Y motors. Also check proper belt tension. Belts should be taught with all slacked removed but not stretched.
It took me a while to get to the bottom of this. I had completely dismantled the drive arrangement for both axis and carefully reassembled them , setting the tension of belts and wheels with great care.
However in the end the issue was rather simple :
I bad previously purchased a rotary for which I had to raised the machine (extended the legs). That had introduced the play that was causing the backlash!
Thanks Berainlb for pointing me in the right direction!
This here was also a very a useful resource to the mechanical settings right:
