bad translation from STL to G-code

[StephanP]

Hi,

I have a strange effekt and I don´t know why.

I have loaded a STL-file from thingiverse.com thing:249213 this is a extruder gear with a solid center part.

If I slice this objekt I get a not solid part. See attatched file.

Could anyone explain me this effekt. (Other slicer prepare the expacted G-code)


Regards
Stephan

Simplify3D is very intolerant of improper STL files. If the file contains intersecting polys then it's going to cut a gap between them just like yours shows. I struggles sometimes making a proper stl with no intersections but it can be done. You can try some of the built in repair tools but I have had limited luck with that.

If you don't think this is the issue then point to the original stl so we can take a look.
