Curving top surface, blobby corners [K2 pro]
Ive experienced curving up on the edges of my top surface, pic(1) and what ive found is that i should calibrate pressure advance, but I was using pressure advance already 0.035.
Ive recalibrated it, but the it was the same 0.035 with the same problem.
So ive done adaptive pressure advance and things got worse. pics(2) huge blobs on the edges, first I taught it was a z seam problem. Ive calibrated retraction, no problems there.
Ive tried scarf joint seams pics(3), with the same result.
My goal is to flatten the top surface, but I couldn't figuere out whats the causeing this problems. My filament was dry.

the model is one of my narrow gauge lego train tracks prototype, made in FreeCAD, exported to 3mf. Ive tried multiple exports, to figure out if its a modell problem, but Ive seen this problem on my other models, but not this as significant as on this.
