3dp-12 (or 3dp-11-atl) dual extrusion?

[Shazam0527]

Has anyone tried using the dual extruder capabilities of this printer? It comes with only one extruder, but as I understand it, it has the capability to use 2. I'm eager to find out if anyone has tried it, how they used it, and where I could find some solid instructions on how to do this on mine.

I'd really like to use the dissolvable support materials

Thanks for any tips you guys may offer!

Sincerely!
