    I have the following configuration on my CR-10:
    - Titan extruder with full size motor (was inside the E3D kit)
    - 45cm Capricorn XS PTFE Bowden tube
    - E3D v6 Extruder with 0.4mm hardened steel nozzle

    Now the problem: The print starts fine but after a while (mostly after 30-60 minutes) the titan extruder grinds the filament and I have to abort the print, unload filament, remove the grinded part and reload filament. It happens so often that I have only a very low chance in finishing a print.

    Further Information:
    - I print gold PLA@200°C
    - E-Steps are calibrated [this holds true for my first Capricorn PTFE. Because of changed tolerances and issues based on these new tolerances they send me an replacement.]

    Things I've tried:
    - I reduced extrusion multiplier from 1 to 0.95 and finally to 0.92
    --> No effect
    - I changed retraction distance from 2.5mm to 2.0mm and 1.5mm
    --> No improvement but a lot of stringing
    - I changed retraction speed from 85mm/s down to 50mm/s
    --> No change
    - I adjusted the tension on the titan extruder and tested various settings between middle and maximum tension
    --> The more tension I apply to the filament, the deeper are the grinding marks, but no improvement on the situation

    Do you guys have any hints for me, how I can solve my problem?

    All your settings look good. I also have a Titan extruder, and this are my settings:
    Retraction distance: 1.50 mm
    Extrusion multiplier: 1.00
    Retraction speed: 50.0 mm/s

    One question: is your nozzle clean ?
    I've had these kind of problems in the past, especially after switching from nGen / PETG to PLA. As the extrusion temperature of the first two is higher than PLA , you can run into problems when you switch filament and don't do a proper nozzle cleanup. I push a couple of cm of cleaning filament through the nozzle after every swap, and since then no problems.

    Thanks for your reply. I think you are right. I started cleaning the nozzle more often and now it seems to work fine.

    Hi everyone my e3d titan is giving me troubles by extruding inconsistently no matter what’s tension the idler spring is. It will extrude the filament and then slip and after that it will grind it then extrude again please help

    What material, temperature, speed?
    Also make sure your retractions are under 2mm to reduce jamming.
