Inconsistent first layer

I have very weird behaviour on my first layer, which I can't seem to get right.
What I have tried:
- Get my frame square
- Z height
- EM tuning
- Temp tower
- different speeds
- different extrusion widths
- different filaments

Its a VC3.1 400 with a Dragon HF and a Super PINDA.
I am using @Helge Keck PAM, so I feel that the important part of the bed is being probed before the print.
Attached are some images, the print startet on the bottom right corner.

I would be very grateful if somebody could identify this problem for me...
