    Hello everybody,
    I bought Rumba Board V1.1. I have 2 step motors at Y and 2 motors at Z axis. I read the marlin code and it says "You cannot have dual drivers for both Y and Z". I want to know why? I can connect the 2 Y motors on both Y and E1 ports; and the 2 Z motors to Z and E2 ports. Then i will arrange the code again for pins. If i do those changes i believe that i can run 2 step motors for both Y and Z axis. But i want to know that why this code is written as "You cannot have dual drivers for both Y and Z". Can someone suggest me some idea about this situation?
    As a note i know that i can connect two motors together into Y or Z axes. But i don't want to do this. Because my motors need 2 A each and DRV8825 can not supply this current as 4 A. I HAVE TO use seperate drivers for both Y and Z axis.
    Thanks to you a lot.
