I'm having problems with some black ABS that I bought, if I manually extrude a few cms, sometimes it comes out straight, but all of a sudden it will start to spin and extrude like a tightly wound rope.

I don't have these problems with the natural colored abs, so I assume it's the plastic, but I can't figure out why it would behave this way. I'm using a trinity labs metal magma extruder, and I've tried temps from 220 to 235 and have had the same results.
I get nice looking prints with natural abs, but the black has been a disaster. A few layers will go down perfect, then some really nasty bumps and ripples, with horrible looking corners will show up. at least 50-75% of the print will have imperfections, making it completely useless.
Let me know if any of you have seen this before.
