and yes, the filament detaches from the print bed in some places.

After 10-15 minutes, the layers become thinner and thinner until no more material flows. I've calibrated the printer several times, unfortunately without success.

[Printing problems]

Hello,

 

I am currently having problems with my printer. It starts to print well but after a good 10 minutes the print head isn't extruding any material. You can see the problem in the picture. A gear wheel is shown. The outer edges work, the inside also starts well, but suddenly it doesn't pull any more filament.
What I've already tried:
- Temperatures of printing plate print head changed
- Recalibrated
- Mechanics cleaned and checked for functionality
- Software updates
- Printhead changed
- Replaced filamend

 

Hope you can help me.
