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.
I tried 235-250° without much change. Even tried uping the flow rate to 1.2 in the preset.
This is the only attempt that did not just fail at like layer 10 or something. And it’s still bad.
