“Not allowed to upload a 3mf file that contains custom printer/process types or filament types” is so vague that I had no idea that you require “Generic PLA” for the filament and spent a day changing everything else on the profile. Please add “USE GENERIC FILAMENT IN YOUR PROFILE” on the upload page to avoid user frustration. Add in other common items that fall under “customer printer/process types” because it’s so vague we don’t know what it means.
