Hello,
Im very beginner of PyCAM.
The test is: Two cilinders and boolean difference, and boolean union on cube scaled.
Then export to stl and this is the log from PyCAM when import:

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
the above warnings tell you that the exported model does not seem to be clean (or: PyCAM's importer is not perfect).
Which program did you use as a modeler? OpenSCAD?
Some people recommend meshlab for cleaning mesh models - did you try that?
btw: how does the object look like? Is it completely broken or still looking fine?
cheers,
Lars

I have had similar barfing due to inadiquite R.A.M. I have watched my computer consume 24Gig of ram processing Blender built stl.'s. A 32Gig R.A.M. card, and a 20Gig. swap file seems to have fixed the problem. Also Blenders boolian modifyers can leave non-manifold edges (non closed geometry). These can be found in "Edit Mode-Select-Non manifold. This might help, but PyCam is amazingly tolerant to dirty geomitry. I have also processed non boolian geometry with PyCam.

I also like to triangulate all surfaces before exporting to stl. because blender will make nonplainer ambiguous surfices that would make MC Escher cringe.

Is the stl model too small ?
In Meshlab I have to scale X 1000, files from 2 different programs
filters... normals... transform: scale
