Ugly prints

Do you have any idea why my print looks like that?
The good one is printed on my Mini, and the bad on my A1.

It’s the same 3mf file loaded on both printers, and I have also tried to swap filament, and they have both been dried. My 2 other printers can print it fine as well. Elegoo / Esun PLA. Also, full plate 1st layer is perfect.

What I have tried:

New hotend
New hotend assembly (The 4 screws are fastened)
Factory reset A1
Reinstalled Bambu studio, using default profile
All belts have been checked
Manual bed leveling
Lowered filament temperature
And ofcourse automatic bed leveling and flow control before print
The cooling fan has been cleaned

Make sure profiles are matching printers when generating gcode, seems like overextrusion, maybe temperature too high, or buildplate selection is wrong, but as i see even sizes of models are different…

Did you use the A1 or A1mini profile in Bambu Studio?

Have you tried using the grease that came with the A1?

Especially for the Z-Axis
