thank you for your reply. So the bed moves up until the value stays constant. that makes sense. (although it looks a little brutal).
After autoleveling, the bed really pushes against the nozzle, so the the it gets pushed down a bit. When printing a brim I can see the traces in the glue I have applied on the glass.
I have done manual leveling and then auto leveling several times now, with the same result. So Im not using auto anymore now, but Id rather do.

I can only speak about my experiences with heating the bed. It takes long and even longer if you go higher with the temperature as you do when printing CPE+. It helps a lot if you cover the printer, close the front and even cover the top. Any cool air from the environment can result in a longer heating time.
This is normal. The leveling process measures the capacity between the head and the build plate. So the build plate moves up and the value changes continuously. Then the nozzle touches the glas and the bed moves a little bit further but the value doesn't change anymore. That is the point the printer knows he has reached the glass and calculates the correct leveling.
Hmm, strange issue, I cannot confirm this behavior. Yes the nozzle is close and the material is squeezed into the glas, but that is important for a good bed adhesion. But I haven't seen that the nozzle scratches the glass or is so close that nothing can be extruded.
