ER65 With TPU

[kevinmoore1337 4]

Im getting a issue when printing with ultimaker tpu where i get er65 error messages. Do the feeder gears need to be tighter then the middle line?

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.

You were correct I let alot of tension out of the feeder gear and have had no problems since.

 

Thanks so much

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.

I also get this ER65 error printing Ultimaker TPU.  I'm at the end of the material roll, could that have something to do with it?

I have an Ultimaker S7 with the material station.  Have been successful printing TPU until now. I get the ER65 error printing Ultimaker TPU. I'm at the end of the material roll, could that have something to do with it?

 

The machine is practically new, and I have yet to consume a roll of material.
