Hello
I am looking for information to be able to print a print, three cylinders superimposed (example) the first black, the second gray and the third white. Would you have any idea of configurations under Cura to get there?
The gray would be obtained with the white and black PLA in the cyclops head.
Thanks for your help

Take a look at attached PDF. it shows step by step instructions to create up to 3 virtual extruders (5 total, 2 physical and 3 virtual). Each virtual extruder can be defined with a personalized mix of color between both filaments.
