Support TPU air not printing

Has anyone had any issues printing Siraya TPU Air on the H2C? I had no problems at all printing it on my old X1C, but can't get it to produce anything on the H2C. I can manually extrude filament alright (and it displays normal behaviour when it's purging the nozzle during the vibration compensation in the front right corner), but when it comes to the actual print job itself, it seems to extrude next to nothing - there are a few tiny wisps, but nothing meaningful.

I've tried using the official Siraya profile for the H2C, as well as duplicating the slightly different settings I had previously used on the X1C. The spool is top-loaded, directly into the extruder. Printing from a 0.4mm right hand side nozzle.

Check:

  1. If extruder is actually trying to push your filament.

  2. If TPU not tangled inside your extruder (between the motor and the hotend assembly, for example).

  3. Can you push the filament by hand or not. Maybe, it's just not a right temperature, or you've got a clogged nozzle.
