Ok, got the printer back to print in an acceptable quality. The singe most important thing was reducing the initial layer thickness to 0.1 mm

Ok today another try.
I solved the issue of the brim getting ripples and wobbly: Turns out, that the Cura default of a 0.3 mm initial layer messes everything up.

With 100 percent flow the nozzle starts to carve through the print ( A flow rate of ~40 % seems to

The history so far:

Since a few weeks I have a Anet A8 and I am still in the 'getting used to it' phase. After printing some stuff to improve the printer itself I wanted to print my first 'real' part. But here the printer fails all the time already when printing the brim. It starts out well, but the lines becomes more uneven, the farther inwards are. Finally the will get so uneven, that the nozzle will tear the part
