Geeetech

Power supply is 24v as well as the fans I've tried. It's a matter of air flow than anything else.

Is there a place to buy a suitable replacement hotend fan ? There's only a 3010 12v fan on Geeetech's online shop. Mine blowned a few weeks ago and since then, no matter which fan I install, I'm unable to print anything but PLA without heat creaping. I've tried everything I could, changed the hotend...

With the right settings, providing your TPU isn't too soft ...

I print 30mm/s, no retract ... don't know the specs of my TPU, I know there are softer ones, but it works with this one.
