How to prime both nozzles?

[alientek]

I am getting horrible prints with dual extruder printing in S3D, my problem is i can't figure out the script that primes both nozzle's at the start.
My start Gcode:

M218 X0 Y0 T0
G28 ; home all axes
M218 T1 X-23.6 Y0.1;
T0;
G1 E12 F225
T1; <= (It skips this part so only 1 nozzle gets primed) why?
G1 E12 F225

So i'm getting poor bed adhesion causing messy prints / failed prints.

I think you need to add a G92 E0 right before each G1 E12 F225 command.

Alternatively, you can also let the software handle this by enabling the skirt and setting the skirt extruder to "all extruders". That way it will prime the nozzle on the skirt so you don't have to do it manually.
