Why these travel lines?

[Kalveo 0]

The blue lines in these pictures are the travel lines (sliced with ultimaker cura). I was wonder why it makes these travels, as the printer is still moving within the same layer (especially the second picture)? Also for some reason the printer does not seem to do retraction (retract is enabled) in this case (it normally does when I print) resulting in these lines being visible as stringing in the finished print.

 

Is there anything I can do to prevent this?

Hello @Kalveo, it would be much easier to answer your questions if you could attach the Cura project file to this thread. Use the file menu save (or save as project in older versions of Cura).

Here is the project file (I think)

MotorMount.curaproject.3mf

Hi @Kalveo, thanks for the project. I fiddled with a few settings and now the travels look less wild. I have set the combing mode to "not in skin" which has been reworked in the 3.5 beta release and now behaves as you would expect. If you are using an older Cura release you will still see travels across air.
