When I change PETG to TPU, I always have trouble and it either prints spaghetti or air prints, most of the time. Sometimes I get lucky and it works for a while. How can I get this to work consistently?
When I send a print from Bambu Studio that uses TPU I get a pop-up saying I should perform a cold pull to prevent clogs. Do you get that message and are you doing cold pulls?
I do some manual flushing at high temp when going to TPU. Crank the heat up to 250 then run about 6 inches of filament through.

I do what @CincinnatiDesigns does in this case because tpu sticks to petg. Just have to purge at petg temps. Cleaning filament is also nice

Agreed. The best thing to do would be to perform some cold pulls and check if you have a partial clog in your nozzle.
