Hi,
Today I have solved a lot of problems.
The problem with the wrong parking position of the focuser must have been caused by the fact that the focuser motor has too low torque now when I have increased the force on the focus axis.
Here you can see how I have temporarily solved it with help of a spring:

Maybe I will have a better solution to it later, but first I must test it out.
