Comment on I want to branch out from PLA. Should I try ABS or TPU?

  A direct drive extruder is one where the motor that runs the filament sits right above the hotend. Since TPU is squishy, the long tube from a Boden setup gives it too much room to squish.

  That’s a bowden extruder, you’ll have problems with TPU.

  Try PETG, just dial up the retractions a bunch and slow it down.

    A1 has a direct drive extruder. It does function as kind of a hybrid thing with the AMS though. Use of the AMS with TPU isn’t recommended, but there are a couple of harder TPU filaments that supposedly work.

      Oh, ok. Every picture I saw made it look like a bowden extruder sitting on the end of the X gantry, with the tube going over to the hotend.
