Sorry to jump in on this thread but im having a nightmare with the Titan extruder and polymax PLA. No matter what tension I have the extruder on the filament it just starts to chew into the filament. The hobbed gear has an approx 3mm grooved part the same width as the filament itself so appears to be the older design?



I have checked the motor is sufficiently powered, it is. The gear assembly is not overtightened and the hobbed/grooved gear moves smoothly. It appears to print ok then just starts chewing the filament. I can push the filament through the extruder by hand ok so I dont think there is a blockage.



Any ideas?
