So I have a bambulab A1 and recently wanted to print something with TPU. The issue I have however is that the extrusion is just hella inconsistent. I get a coupel seconds of normal extrusion and then a couple seconds of pretty much none. The first layer was only half filled when I checked and I want to know if you guys have any suggestions.

I used the base preset for generic TPU.

This is the first layer I get after trying a couple different presets. Better than before but still horrible.

Is your filament dry? With TPU, it's the first time that I saw a drastic difference of print quality. I dry my TPU for 3 hours at 45°C each time before printing.
