This part enables you to use 2 extruders with one hot end.
(1.75mm)
Iv'e tested it with a light6 and so far the concept works well, I just need to tweak the g_code a bit to deal with the excess material that hangs around after the purge of switching extruders.
You will need three 1/8 push fittings to connect this, the brass ones thread better for some reason but will need to be drilled to allow the bowden tube to pass through.
Search ebay for this part "PC4-01" to get the predrilled kind, although they may require some heat to thread properly.
As for firmware, if you want to use a ramps board in the configuration EFB (Extruder,Fan,Bed) you will need to make some adjustments to the pins.h file, you need to enable the second extruder under the EFB area by replacing -1 with something else, also you will need to change the thermistor pin for the second extruder to match the one of the first.
