Hi all, thought you might want to see what i have done with the 3D Chameleon on the M5C. Yes I am feeding a bypass line in as well so I have 5 colours, 4 automated and 1 manual change., using a trianglelab Y connector, I had lying around for the manual bypass. The Y connector is screwed into the top of the extruder assembly.
i run the manual/bypass filament, when needed, through the center of the 3D Chameleon Y Adaptor. It does have to be completely unloaded when not in use though.
I'm curious about what you're using as a filament buffer?
