Dual Extrusion with ReplicatorG for The Replicator™

First, you'll need to find a dual extrusion model to print. Go into ReplicatorG's "Thingiverse" menu and select "Dual Extrusion models!" It will bring you to every Thing tagged "Dualstrusion" on Thingiverse. 1.1

Any dual extrusion model you find is going to be composed of two .stl files, one for each color or material. Make sure you download both. Then go to ReplicatorG's "Gcode" menu and select "Merge .stl for DualExtrusion."1.2

You'll see three fields: one for each extruder and one to name the merged file. The fields for the two extruders will accept either .stl files or Gcode you've already generated. The merged file will be Gcode, so give it a .gcode file extension.1.3

When you click "Merge" two windows will pop up -- one to generate the Gcode for each of your two component parts. These will look a lot like the Generate Gcode window you've used for single extrusion. 1.4 Make sure to check "Use default start/end Gcode" and "Use Print-O-Matic".  You'll also want to make sure that "Use Raft" is unchecked for both items -- rafts currently don't work well with DualStrusion prints.

After you're sure that this looks good, click "Generate Gcode" in both windows.

ReplicatorG will generate the two different sets of Gcode and then put them together. 1.5 When it's done, you'll find yourself looking at that .gcode file you came up with a name for earlier. Go ahead and print it just like you would any other generated Gcode! It's as easy as that.
