I’m going to attempt some models that virtually the only choice is to use water soluble support. Worse, the areas where the support is touching needs to be fairly smooth when done. In the CAD package I’m using, it is very easy to have it make a support “part” that can be merged together with the actual part prior to printing.
In a case where there is zero gap between dual extrusion merged parts, does Cura take this into account during slicing to make sure the extrusion of both materials is not trying to fill the same space at the interface where they touch? Hope that make sense.
