The issue with Atezr L2 24V autofocus is only applicable to specific thicknesses

Hello, I have recently had a problem with the autofocus of my Atezr L2 24w.
When I use the “Autofocus” macro ([ESP500]), no particular problem on 3mm plywood but when it is necessary to do it on 6mm, the laser head continues to descend even if the micro switch is in contact with the board and it crushes it.
As the problem is new (I had no problems 10 days ago, I thought it came from lightburn and I extended my license to be able to benefit from the updates, but that did nothing . So I’m running version 1.7.00.
I haven’t made any changes in lightburn or on my machine recently, so I don’t understand the problem…
I am at your disposal for further information, thank you to those who are willing to help me
