I had a problem. I do not know how to print two nozzles simultaneously. Do you detailed instructions on how to do this using Slic3r?
in short: if you only want support to be a different nozzle you can edit the settings of a material. if you want 2 colors on the same object you need to create 2 separate 3D files ( 1 for each color) and place them together and choose 1 separate material settings.
Is this what you're looking for?
for use PVA it's juste set option inside software, but for use tow color I never found how.
