Has anyone had success printing matterhackers pro pla (black) on matterhackers pva? I’ve done the fan upgrade on my dual extruder to reduce the heat creep as well as i have a 6in desk fan positioned in front of the printer that i turn on after the first layer goes down. Is matterhackers pva too flexible? Could it really be my pla color effecting this adhesion? Should I try ultimaker pva as it is supposed to be more rigid than most pva?
