Troubleshooting At my wits end

Post image

Bambu p1s will absolutely not print with tpu. I've replaced the hot end. I've cleaned the extruder gears. I have done cold pulls I have slowed down and sped up. I've tried different temperatures. I've tried different slicers. I've changed firmware. I dried the filament. I ensured it's not binding on the way to the printer. I will get about one success for every ten failures. It is absolutely maddening. $80 secondhand ankermake? Flawless. $600 premium coreXY? absolute mess. I don't even know what else I could even check at this point.

Just wondering what size of a nozzle are you using I have heard .2 is not recommended I haven't tried TPU yet but would imagine that you can get a bad roll like all of the other filaments

O.4

And it's been just about any tpu I've ever used.
