What could be causing this rough surface?

Hey guys,

I keep getting this rough surface on this part, always in the same places. Printed with colorfabb XT black on UMO at 250 degree.

Thanks for any tips

Can you see any difference in the layer view in Cura?

You might be getting in a thinner or thicker section which cause that section to fill with a different number of shells compared to everywhere else.

That would depend on your print settings but just a guess.
