Setting the 2D extruder in Repetier

Vertex 3D Printer Vertex - Printer software (repetier, slicer, ...)
1

I am slicing with Cura choosing the 2D extruder (yellow) when processing the stl, when it’s sliced the result jump to the the 1st extruder (blue).
I’ve been through the all thing without finding the solution to get a Gcode to print with the 2d extruder.
Help! Thankx…

You must use ‘Vertex Single Head’ in the Slicer tab /Print Configuration. And select the “EXTR 2” In the ‘Object Placement’ tab.
