Monoprice was having a nice sale today, so I picked up the 3D Printer dual Extruder Heating assembly (http://ift.tt/2bRkpTq). What else do I need to buy to get my Monoprice Architect (Flashforge Creator clone) to dual extrusion goodness?My research seems to indicate that it’s a pair of NEMA17s, a pair of Mk8 feed kits, a pair of stepper gears, a pair of heat sinks, and a pair of fans. But I have no idea if there’s specific models I’m supposed to buy, or if there’s better stuff. Your thoughts are appreciated. http://ift.tt/2bWop4W
