Addition of articfact when using TPU95

[DrBwts 1]

Cura 4.11, Ultimaker S3, Ulitimaker TPU95

 

Whenever I use TPU95 I get an extra circle added to the project,

 

 

Which when printed comes out like so,

 

 

The TPU ring on the artifact is prinited on top of the PLA disc. Anyone know what's going on here?

I'm not sure, because I don't have a dual extruder printer and have never looked at the related settings, but to me that looks like a prime tower. Not sure why it would make one if your print is entirely TPU (no supports etc. in PLA) but you could check any settings related to "prime tower" and hopefully that's what it is and you can turn it off!

@43915 is totally right.

The prime tower is automatically generated when extruder 2 is involved, no matter if extruder 1 is used or not.

If you want to get rid of the prime tower, just disable it in the "dual extrusion"-settings.
