    So I have the wiring with the new ramps 1.4 board. The 5 drivers. The hotends and bed heat up correctly. The 2 extruders I mounted on the side of the robo r1+ are not turning at all. I checked the voltage on the drivers and even got new cables to run to the nema 17 motors. Maybe I'm missing something in the configuration of the firmware?

    possible. Pull up your firmware, go to the extruders section in the config.h should have 2 enabled. Even if only one was enabled the one extruder would be working. Tune your stepper drivers. Dual extrusion is quite a task to pull off so we need much more information to be able to help you (like you config.h file and exact details on what you did).

    Sorry I'll post my config.h file when I get off work. I know is switched motherboard to 34 and changed extruders to 2.
