Engraving offsets after awhile

Hi all, When using Lightburn my laser (X Tool D1 10W Win 10) jumps to the right after a certain amount of run time, it only jumps on the X axis. never the Y. And yet when running exactly the same file in Laserbox it completes the job with no issues, which kinda makes me think it’s not an issue with the belts, which seem to be set about right, i’m running the latest version of both Lightburn and Laserbox and the XTool software is up to date, pics below show the offset and the perfect run, as well settings for Lightburn and Laserbox. Has anyone come across this before? Seems like a Lighburn issue?
