Little bumps on the surface and how I got rid of them

[fuh 1]

I noticed that the infill left not only a little ridge where it overlaps with the shell, but also little droplets now and then. First I thought this doesn't matter because it is inside the obect. But then I noticed that on the following layer, these droplets are sometimes dragged to the surface when the shell is plotted, and there they remain as bumps.

I simply reduced the infill overlap (in the experts menu in Cura) from 15% to 8% and the bumps were gone.

Maybe it's helpful to someone.

Do you have any pictures of these bumps? I'm not sure I understand what kind of bumps they are.

Like Robert said its hard to know for sure without seeing anything and from what I understand it could come from a number of things.

Infill overlap is covered already, print speed, change in speed between infill and shell, nozzle temp, retraction settings.

The good point is that you found a way to get rid of it

Photos will come later.

Does reducing that overlap setting affect bridging or top-layer in a noticeable way?
