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.
