Dual extrusion can't Offset

[xTremePower]

Hello,

I buyed S3D specially for make dual extrusions, but I can't setup the offset ..

I have a Zonestar D805 dual (Repetier firmware)

after a couple of hours I am totally unable to setup the dual extrusion ....
I tried all this things :

-Setup the offset in Options , machine , toolhead offset, I tryed to set many values for extruder 0 and 1 bot it's change nothing
-Tied to change same values in FFF setttings in g-code tab, change nothing
-Tried to include the offset in the G code with Apply toolhead offset in gcode coordinates, the printer use only a single color (and wery awfull model preview ...)
-Changed the offset directly on the printer screen, when I launch the print, he reset all values to default...


How can I set this Offset please ?

Thanks
