ABS extrudes "zig zag" MBREP2

Flat parts = level build plate.
Curly parts = not level built plate

Level build plate again - don't use business card, use paper.

The nozzle not close enough to the bed.

Thanks for the answer!
It was the leveling, because I leveled the plattform like I was used to when it was cold, but the springs underneath the plattform seem to change due to the thermal change of the new heating bed. So the hot building plattform was suddenly far away from the nozzle. After leveling it with the hot plattform it works now
