My TAZ is about three weeks old now and I’m getting very good and repeatable results using ABS. I am going to try out HIPS filament but want to check if there’s anything I should know before I dive in. Specifically, should I keep separate extruders for HIPS and ABS? (I used the same one with ABS and then PLA, and then back to ABS. As a bonus I got to learn how to unclog an extruder nozzle…8v) Any other “gotchas” I should know about?
