Got a Taz 6 2 weeks ago and have printed almost every day with 4-7 hour print jobs. Mostly nGen prints. Works great so far but I am getting black goo around the nozzle area. It sometimes comes off in the prints as well and I suspect it is from the Elmer’s glue stick adhesion.
Been 3D printing for years and normally use hairspray on a glass bed for PLA adhesion (and it has worked great all these years for me). All my other 3D printers have clean nozzles (Makerbot 2 old gen, Robo3D, 3 printer bots) and they have all been workhorses.
So I suspect it is the glue and I am just putting it on a bit too thick (I didn’t think I did but I’ve never used it before so…). I can fix that but I am wondering if that is what it is and perhaps the best way to clean it off. It doesn’t look like it will come off with a simple towel.
