Snapmaker Inline issue

Dear Snapmaker 2.0 community,

Recently changed my Lightburn 1.4.05 setup to Marlin (not SnapmakerMarlin anymore) to get the inline mode. Ran a file i had, ready for production. The result was blank… but the laser was working (i guess not enough power)

I then ran an even older file, which is a burn test generated by Lightburn.
On a known material, the result was way off the usual…

Any advice is very much appreciated !
Would updating the Lightburn Software to a newer version and switch back to SnapmakerMarlin be better ? Would i then also need to update the machine’s controller ?
or what could be another solution ?

Kindly,
phil
