Since i updated Cura from 2.7. to 3.1. I have a really hard time at configuration and especially removing the support interfaces. The update automatically uses the settings from the old version, but as I said: it doesn't work anymore.
I even tried to create a test print with 4 copies of a test object with different settings, but there where no differences in the slicing for them. Every copy and the support interface that belongs to it was the same.
Did anybody have an idea?
