Can't print the object without filling

Using vertex repetier with Cura plugin I can’t omit the filling of my object. If I choose 0 %for filling overlap he keeps the filling raster. How can I manage that there is no fiilling, just an hollow object, like I made in FreeCad.

What do I wrong. Use a Vertex K8800 Delta.
