E3D Titan Extruder and PETG?

Struggling to get PPE to print using an E3D Titan extruder bowden setup and PETG. There’s one spot where there’s a lot of retractions, and the PETG is getting chewed up to the point where it stops feeding because it won’t fit into the bowden. I’ve tried Capricorn, cheap chinese, and factory bowden, and multiple different pressures on the tension adjustment for the Titan.

Any tips?

Answer this question I have this problem too

Is this a good question?

Hi Jeremy,

Grinding filament with the Titan is an indication of a couple of factors

Firstly that the tension is set too low, increasing the tension provides more grip.

Secondly, that the motor/ stepper motor is not ideal. We recommend using the compact but powerful motor for the Titan, which is rated to a max current of 1.68 (make sure your stepper driver is calibrated to provide that value)

Thirdly the nozzle is jammed, running cleaning filament/ a cold pull will help clear any degraded residue that may be causing either a partial or full blockage.

Another option is you may be using a non E3D HotEnd, unfortunately, we would not be able to provide any further support in this case.
