Does anyone have ideas about what could be happening? Is this an indicator of too high or too low temperature?
I only once got anything resembling crunchy when my thermistor fell off and the heater went full blast. Lots of smoke though was a bit of a give away.
Darker colour is also a sign of too hot.
Too cold just fails to bond with the previous layer, or if it way too cold fails to extrude as it is too viscous.
A good temperature to use for ABS is 230C.
I sometimes get crumbly filament when I change from one plastic to another until all the old stuff is flushed out.
Another cause could be a lot of moisture in it. Has it been stored in a damp environment?
The filament i'm using is already black, so i cannot see the color.
Its been stored inside, so i think that's probably ok. i'll try a lower temp.
