@paulsroom not sure about extruders, or minimum nozzle size for Polysupport but I have done two colour printing, using various softwares.
I did start with a test piece like the road cone or similar so that you can understand things, and possible start with a DIY two colour part. I model them up in CAD, and select both objects and export as a multipart stl, but you could do a couple of 3mm thick 20 x 20 squares and do a Bassetts Allsorts type tester too.
If you add this model in AutoMaker, it will load correctly, on macOS you hold down the cmd key, but it's ctrl elsewhere, and that way you can select and drop both stls linked onto the build plate when you Add Model
Support is automatic if you check the right boxes under the Support tag in the Make section, and @bhudson recently mentioned this the other day, but I also make a support model in CAD too, almost tree like, and if you want print part of it the same material, and add a smaller layer of poly support aka like cartilage on a bone to the area that will interface with the model. It might seem like hard work, but it does give good results too, especially on snap fit clip details I have made, where I cantilever the support into the model, and the support doesn't "contaminate" the surface.
