Avoid travel moves over printed object

Hey Community,

is it somehow possible to slice a print so that the extruder never moves over the previously printed layer during travel moves? I print transparent objects with PETG and the travel moves always smear the surface, which leads to a worse transparency. I played around with "avoid crossing perimeters" and "seam position", but that was not satisfactory.
In the picture below: I don't want this blue line (travel move) to be over the previously printed surface.

Is there any way to set the extruder to move directly out of the object after infill, and only move back onto the object when the next infill or perimeter begins?

Thanks for your input 🙂

Yes it is.  First you must be in expert mode of Prusa Slicer settings (top right of the screen). Then open the 'printing configuration' menu, go to 'layers and perimeters'  and scroll down to 'quality' settings. 

You'll see an option called 'avoid crossing perimeters'. Just enable it and you're done.

Unfortunately, this does not lead to success. In the image above, "avoid crossing perimeters" is even activated

Avoid crossing perimeter strikes to keep the nozzle inside the model, not outside. Have you tried enabling z hop... (z lift)

I try to make safe suggestions,You should understand the context and ensure you are happy that they are safe before attempting to apply my suggestions, what you do, is YOUR responsibility. Location Halifax UK

There is no setting to avoid already printed models during travels moves.  Z hop lifts above but will still travel 'over' the area.

Z lift is unfortunately not enough for my purpose.
I already thought there was no option for that. It's a shame that you can't modify the slicer individually. There are often things that you can't adjust.

Anyway, thank you very much for your ideas 🙂
