I just started on a roll of black ABS from MakerGear, and my extruder is shredding it (not pushing through). I had been printing with Safety Orange (MakerGear), Royal Blue (MakerGear), and Red (from Ultimachine) prior to that with no problems. The filaments from MakerGear all feel softer to me than the Ultimachine ABS.
Has anyone else tried multiple sources, and found this kind of variability?
I typically print my ABS at 250. The Safety Orange worked better at 260. I have a feeling the black ABS might need a lower temperature...
I'm going to clean up the extruder, and try some of my leftovers, just to make sure it's not the extruder that's just misbehaving.
