My model was fine:
edited it slightly, a little narrower, a little shorter, and now its impossible to print
the CAD is solidworks2016,
I had the issue with s3D 3.xx (cant remember the numbers), upgraded to the latest, still the same issue.
Went back to solidworks and tried all sorts of settings on the resolution of the stl, no progress there (S3D exactly the same)
Ran all the repair stuff that would run in s3d, got nowhere with that.
So it looks like i hit on some sort of dimensions in my model that S3d just fails to slice correctly.
Whats with that?
I've attached the STL
I'll print the parts on a printer that accepts gcode instead of x3g. I just cant get a decent slicer that will make x3G files that run on my flashforge creator pro. I'm stuck with this s3d issue.
