I’ve been trying to print some things in TPU, using a fairly soft 85A TPU, and I keep having under extrusion.

I’ve already reduced speeds to max 25mm/s, and reduced retraction. My printer uses a direct drive extruder, and as far as I can tell, it’s grabbing the filament just fine. I’m printing at 240°C, using my default 0.4mm volcano CHT brass nozzle.

      Great! Good to hear.
      Don’t forget to turn it back down with less springy filaments.

        I have seperste filament profiles for everything, so these changes only affected my “TPU 85A” profile
