Nozzle cleaning filament to aid color changes

My experience with moderators on discord and here are of being spoken to as a fool. I have over 40 years as a software developer, twice won Microsoft’s MVP award. Held patent-pending for an inkjet-resin hybrid. I tried the default setting for purging, then tried the auto calculated settings. They were not sufficient. I got insulted and berated for dating to suggest an alternative like the swapper 3d concept. Socialist media thinks a minimal amount of respect is sufficient. What that does is make people not contribute.
