gap at seam

Hello,

I have a prusa mini with a bondtech extruder. Everything else is stock. It prints very well outside of that large gap at the seam of my prints, see picture attached.

I print with polymaker PLA polyterra matte black, on a 0.4mm nozzle.

I've read that this might be cause by a too long retraction so I changed it to 1.5mm compared to stock but that did not seem to change anything. I adjusted retraction speed to 35mm/s as well but no luck.

I've also tried to change the seam distance percentage (lowering from 15% to 0), again no change observed.

Could anybody give me advice on what to try next, I'm fairly new to 3d printing and so far I'm not able to figure this one out.

I would prefer a bulge that I could sand at the seam rather than a gap 🙂

Thanks a lot in advance,
