I have an stl object that slice well in Slic3r gui, but not in Repitier host gui!
I suspect that Repitier is not tolerant (too precise) on small inaccurancies. My object (Sketchup) is made of different object groups, all fitted together to make the final object. In Repitier, the object looks fine, but slicing it, some "pieces" are missing, directly slicing with Slic3r gui there is no problem!
