    As I said I'm not sure about it, but two motors need twice the amperage, so you need to increase stepper driver voltage.

    Just be sure to install a heatsink and if possible, an airflow towards that driver...

    Yes, i do think all the non 32bit boards are the same no matter which printer. In fact they're labeled E0,E1,E2... Rumba and Rapide is the same board with just a few differences (besides the driver installation, the reset function on rapide is NOT present on the rumba, but you could still remove the microswitch and place 2 pins instead, to take advantage of the reset function).

    That is not correct.
    You don't need to change voltage if the motors are connected in parallel. They will consume 2x the amperage but using the same voltage.

    Quite a lot of things going on in this realm. I was considering the V3 extruder upgrade that is available in June but am thinking I should watch what happens here with these.

    I have already received the 4 nema's steppers, the relay board.
    I will receive soon an E3D V6 extruder, and the small material.

    As soon as I receive all, I will begin.

    So which system will you be testing?
