@engikeneer same slicer same profile indeed. i tried another bed leveling example (https://www.thingiverse.com/thing:13053/files) and it worked. Something with the *.stl with the other one is wrong, when i sliced it with Cura it didn't show anything in the preview - which isn't normal.
I will try to fix my current bed leveling aka adhesion issue with the new test file.
Thanks for the help.
