Hi Hauke!
Thanks for this feedback- I think we found the solution to my problem
You can’t really see the wear when its inside the print head but today I dissembled it to check if it can be tightened.
I realized my extruder gear does show some wear and that could be the issue why I sometimes may get minor slip and also be the reason why my E steps are that high at 260
The problem is that I can’t change this gear or I don’t know how.
