Useless head movements in PrusaSlicer I love PrusaSlicer but I am having a problem.
As you can see in the picture the head makes movements that seem useless
(blue lines that come out of the print in the corners and go back instantly in the object) and these make damages to the object during the print.

How to configure PrusaSlicer so that doesn't happen again ?
Thank you.
Edit : Thank you for your answers but I think we have a misunderstanding. I already have z-hop activated, the real problem is that the slicer makes the head move outside the print (that's what you can see on the first screenshot, every blue line crossing the print shouldn't exist).
I actually don't have this problem with curaengine on repetierhost as you can see in the following screenshot :
I found the solution :
It was the option &quot;avoid crossing perimeters&quot; that seems to do exactly the contrary of what it means.
Thank you all for your answers.
