Two Z-axis motors plus 3 extruder motors on Rumba board.

I am thinking of using my Rumba Board with my Diamond head on a Prusa I3. In addition to the three extruders, I intend to use 2 Z-axis motors. How do I hook up the two z-axis motors. My guess is that I twist my two black wires together, my two green wires together, my two red wires together and my two blue wires together, then insert each twisted wire pair into the appropriate terminal. Am I right? Do I need to change my DRV8825 amp settings any different to what I have on my RAMPS 1.4 board? Do I need to make any changes to my Marlin setup other than choosing the RUMBA board as my main board?

Thanks,

Stuart

Mine are wired in series as shown at [reprappro.com] . I've seen a number of cases where people have said wiring in parallel is problematic.

Thanks for your response.

If possible, you should consider one Z motor and and belt and pulley setup. Much more repeatable leveling.
