Can't print TPU (60A)

Hi everyone,

I'm trying to print some TPU (Filaflex 60A Pro White) on my MK2.5S (last firmware to date) with a 0.4mm nozzle.

I can't manage to print anything, the filament does not extrude. I gets tangled in the idler and wraps the gears.

Event if I try to push it manually down to the nozzle, it ultimately gets stuck in the idler.

I've tried multiple temps (215, 230 and 270) and multiple tensions in the idler:
 - loose, almosst holding the screw
- average, PLA like
- hight tension, stongly screwed.

If' cleaned the nozze by doing a cold pull.

Can anyone help me? Thanks

I don't any experience with TPU, but have you tried slowing the print right down? Combining this with loosening the idler a little would make sense to me from a physics/mechanics point of view...

Thanks for your answer.

I've slown down the print speed to 40mm/s.

When trying to extrude the TPU, I'm using the knob (Parameters > Move axis > Extruder) to do it slowly.

Non, it did not help.  This was my workflow before my initial post.
