No Filament transport with MK8 Extruder

[BR365]

Hello,
we assembled the Geeetech I3 Pro C Dual sucessfully, but the filament transport seems to not working. When printing from the PC software, there is only one little drop of filament on the nozzle.

Is it neccesary to set up the E-Steps for the filament transport?

Regards,
Moritz

I found the problem: The connector for the stepper motor of Extruder 1 and 2 were interchanged. Now, it works fine.
