I am afraid the usual thing happened when someone is asked to give full details on printer- and slicer-settings. I went thoroughly through my settings to make sure everything is consistent and reasonable. I reduced the printing speed from 90mm/s to 80 mm/s and I lowered the line width from 0.6mm to 0.45mm.

Now my extrusion problem is gone. My best guess is, that there was a back pressure problem, because of the high flow.

The result is not perfect, but I can absolutely work with it and do not have to cancel prints anymore. However, I am little afraid that this problem might come as soon as I raise the print speed. But for now I am good.

@Phaedrux Thank you for being my Rubber Duck. 😉
