Random Lines in 3D Prints on Ultimaker S3

I'm new to 3D printing and I am experiencing random lines in my 3D prints. Does anyone have any ideas as to what might be causing this?

Locate the "combing" setting and set it to "not in skin".  That will get rid of those lines.

 

Combing allows non-retracting moves (which is faster as you don't have to retract the extruder) if you aren't bridging an air gap but if you don't like those lines you can just set it to "not in skin" and it will barely change how fast your print is because it only affects top and bottom layers (internal layers that can't be seen will still do combing).

By the way you can tell if a move is a retracting move or not in layer view as there are 2 types of non extruding moves and one is dark blue and one is light blue.  One of those are retracting moves (e.g. moves that cross an air gap) - I forget which color is which.

Thanks for the advice and explanation. I'll give that a try. I found Combing Mode setting in the Travel settings.

Advice for using cura.  You don't have to know where it is if you know the name or part of the name.  Just enter the name in the search box at the top of the settings.  It will show you the result even if it is set as a hidden parameter.
