Unwanted circle object added?

[ClimbingInnovations 1]

When printing with Nylon and PVA support, (it may happen with others) an unwanted circle of PVA material is being created in the corner?  The circle will go the entire height of the build obviously taking time and material.  It is not part of my model and will be there regardless of the model I select.  It goes away when I deselect supports.
Why is Cura adding this?  How do I turn it off?

It's called a "tower".  You can disable it.  It's a checkbox.

 

I usually leave it.  Yes it wastes material but you get a cleaner print.  When one nozzle is inactive it leaks for the first 60 seconds or so and extrudes a tiny little sausage.  When it starts printing again that "sausage" gets attached to the print.  If you don't care about those you can disable the prime tower.

 

Alternatively you can change the location of the tower to make it closer to the print to save a little time.

Thank you, I had just discovered that somehow that option got turned on.  I have had very clean prints without it so turning it off makes me happy, I had just never needed it before and therefor unaware of it.

Thank you.
