Prusa Research MMU2S for 5 color printing -OR- Diamond Hotend for 3 color mixing. These are the multi material setups we should seriously consider. the 3 nozzles you aren't using on that kracken will drip and destroy every print. ONE nozzle only. The Diamond hotend throws up a lot of heat as it is such a large heated tip. It needs a robust cooling fan to prevent heat creep. I setup a 3 color mixing printer once. But today the software has caught up: https://www.reprap.org/wiki/Repetier_Color_Mixing I am currently balls deep in setting up a MMU2S with a 32 bit controller(SKR 1.3) and as soon as I am done with that i am going to convert my 3 color mixing printer back to its original form so i will have one 5 color printer and one 3 color mixing printer. And Only One extruder tip on each!
