Uninterrupted outer surface

Hello, 

I am trying to print a 3-dimensional hexagon structure, see photo.

Surface of part

The outside surface is purposely a single layer thin, because it is supposed to be as translucent as possible. I noticed, that the surface is not closed along those edges of the hexagons, where the extruder *starts* to print each layer of each hexagon front surface.

Open surface

When checking the extruder run in Prusa slicer, I noticed that the outer surface is not printed in one uninterrupted line but the extruder starts new for every hexagon front surface. This is probably what contributes to the issue. 

Extruder path

In the 3D design, the outside surfaces are fouled, so the 3D design is not what is causing it. 

 

Here is my question: Can I get Prusa Slicer to extrude the outer surface in one uninterrupted path per layer?

In advance thanks for your help! 

Regards

Thomas

Sorry folks, bear with me, first post. I was too stupid to get the photos right. Now with photos:

The outside surface is purposely a single (0.4mm) layer thin, because it is supposed to be as translucent as possible. I noticed, that the surface is not consistently closed along those edges of the hexagons, where the extruder *starts* to print each layer of each hexagon front surface.
