Stumbled across this on thingiverse and decided to give it a try.
Bowden dual/quad extrusion extruder (single-nozzle single-drive) + video found on #Thingiverse www.thingivers...
I originally tried on the stock Anet board as it only has the one extruder motor output and this seemed perfect. It did actually work but I had some issues with my connections and the servo jittered a lot.
After putting the project on the backburner for a while and swapping over to a ramps 1.5 main board I gave it another go. AND IT WORKS.
It basically thinks the second extruder is the same motor as the first one in the firmware you change the pins for E1 to match e0 only difference is you have the direction for E1 reverse. If you follow the guide it explains all.
Actually pretty clever, and opens the possibility to have quad extrusion with 4 colors
Took using the toolchange script for this y splitter and modified the retract and prime lengths to suit my setup.
