Topic: slic3r 0.9.9 gives crazy Gcode for SketchUp geom

Hey folks, long time lurker, machine's running great with Lawsy upgrades (thank you!) and an E3D hot end.

But with the hardware working, I have a software problem I can't get past:

I can't get a decent slice of a lot of SketchUp models!

I check that they're solid in SketchUp (using SolidInspector), and I've try exporting with both the "Export to DXF or STL" plugin and DAE to Meshworks, then check in AccuTrans-- all A-ok.

The STL looks good in Repetier Host (0.85b), but it slices too fast (with slic3r 0.9.9) and the result is garbage: like it can only see a few edges, and it makes a wispy spiral up with no real extrusion.

It's not an SD issue per se, but my setup is pretty plain as far as the SD3 setups go.

I'm attach the latest stl that's tripping it up-- so simple, hmmm...

Any clues would be most appreciated!

No attachment...

It could b that the faces/normals are inverted. RH has something built in to fix that, have you tried it?

Gah, sorry stl attached here.

I don't see any normal fixing tools in RH, but I'm running an old version, maybe time to upgrade.  I'd rather fix it in SketchUp of course, but I'm new to it and it obscures basic stuff like that...

That object isn't manifold by a long shot attach the .stl so we can have a look.  Remember in Sketch-up if it is gray it isn't manifold.  If it is white it is manifold.

Try slicing this version I had no problems with it after I ran it though Netfabb.
You should consider upgrading Slic3r and R-H.

Thanks @wardjr, I think it's time to upgrade and expand my toolset.

I blame SketchUp btw-- I ran "Orient Faces" which seemed to unify the faces, but they drew blue, indicating reversed.  That sliced fine, but it seems like it shouldn't have.  Hmmm.

Thanks again for the help, now to print without curling or moiré patterns, whee!

Fear not there are easy fixes for all of those things.

Re: slic3r 0.9.9 gives crazy Gcode for SketchUp geom

I had issues with sketchups stl export files when trying to import them into a different program. I think it's prob in the plug-in and not so much sketchup itself.  So, I started using 123dDesign. I most recently started learning to use Blender a little bit.
