I've never printed TPU but I'd think a low tension would be better. It's pretty flexible and you definitely don't want it getting bound in the feeder gears. Maybe take your gear cover off to see what's going on? Make sure that your remove as much tension in the spring as you can beforehand.

I'm having the same issue. However, I did release quite a bit of tension from the feeder already. It's a 20h+ print, and it has now stopped twice due to the error during printing. 

However, when I resume it prints perfectly again for some hours and then suddenly the error appears again.

 

I disabled the flow sensor for now, but would prefer to keep it on.

 

Any ideas?

    With TPU I find it seems prone to partial nozzle clogs. Not enough to be that noticeable in print quality, but enough to trip the error. More frequent print core cleanings seem to help a lot for me.
