I dit run full calibration.

I noticed this when i tried to print this models “9 Brain Teasers with Varying Difficulty Levels - Free 3D Print Model - MakerWorld” And pieces did not fix.

I run same model on A1 and no corners bumps!!.

Any ideas?

Thx

It looks to me like the model’s seam is the issue, and the a1 hides it better. Have you done Fkow rate calibration and pressure advance?

Doesn’t it do that automatically?
