Looking at setting up a dual material workflow using blender and slic3r.
In blender, I create an object consisting of two or more meshes with materials (using boolean difference and scale command for exact alignments), then from blender edit mode, use P command to separate meshes into different objects based on assigned material.
Then export these objects, one for each material, in STL format.
In Slic3r, load one of the STL objects, then with the object selected, right-mouse-button -> settings and a sub-window pops up, and then select load-part for any other material STL files, assigning the extruders.
The parts seem to be aligned correctly and all looks fine. The idea is then to save the whole thing as an AMF file, which can then be reloaded and printed. Unfortunately, when I click OK in this sub-window, Slic3r aborts.
What I would like to know is, is this workflow approach correct and I have simply hit a bug, which I should report, or am I trying to do something that should be done another way?
(I am using slic3r version 1.3.0 on ubuntu 64 bit. STL files are attached.)
