Problem with Up! plus 2 printer removement filament

Hello,

since a few months, I've got a problem with removing the supporting filament from the object I want:
- You have the filament on the printerbed , form printerbed to printerbed (thats not a problem)
- And you have the filament at the object, from printerbed to the object (and thats a problem)

In the past I just could take it away and I had a smooth surface. At the moment, I really have to work from taking the filament away from the object. This ruins the surface of the object.

Does anyone have this problem too? If yes, do you know the solution?

I had problems wih the calibration before and now the nozzle is a bit closer to the printerbed. Maybe that solve the calibrationproblemn, but causes this problem.

Does anyone have a solution for me? Otherwise I can't sell the products to other people.

Thanks!

René
