Nozzle scratch on top layer?

Bambu Lab A Series Troubleshooting
1

Hi Bambu community,

I recently printed some gridfinity parts on my A1 with the Sunlu PLA Basic and some tweaks on the filament settings, like 0,985 flow, nozzle temp of 200c 100% cooling beginning at layer two etc.

However I realized I am getting weird scratches on the edges of the top layers. I already did a re-calibration.

Do you have any idea what the reason could be?

Thank you all!

It looks like a bed adhesion issue to me. Make sure the build plate is CLEAN and you may want to bump the bed temp +5 deg.

Thank you for the point! Seems like a plausible reason, I will give that a try!
