Need Help with Camera Calibration file

Hey Guys

Im installing my mintion lasercam to my Commarker Omni UV laser and currently try to set it up in lightburn.
But I fail in the second camera assistant. Where u are supposed to laser a specific 4 dot file on a blank piece.
I can not change the operation settings for my UV laser. It it at 200 qPuls standard setting. And with that I see none on my piece of paper.

I would like to then manually upload that file in lightburn. Not through the assistant (because that blocks the change of the settings)

How do I find that file?

Please I need help
