I could need an idea what my problem caused here.
As you can see, the right side (green arrow) is good and the left side (red arrow) makes little trouble.
I'm thinking about print-bed is not plain, but.., should the ABL not correct this?
Any other advice?

Manually level the bed, ABL is a lazy work around. Top end CNC machines are level, not compensated for level.
