Can't find in forum search. I'm trying to use some 20% wood PLA at the moment but it doesn't seem like the 3DChameleon wants to actually grip the filament to move it around.
Also don't know how abrasive the filament is to the insides of the 3DC long term.
Have you tried inserting it into a different extruder like number 2 or 4 instead of 1?
