    Hello,

    I have bought the Sphinx 55 and the Black Box. When I went through the documentation of the current adjustment I came along this explaination.
    • Adjust the current until you can no longer stall the motor under normal operating conditions.
    Could someone please give me more information about the "how to?"

    By this explaination I understand that I have to take hold of the shaft ( nema 23 ) with my hands and try to hold it for as long as I can while turning the "pot".

    This can't be the way... or is it ? Confused and feeling like an idiot... .

    Only if that is your
    Hehehe

    But no, on the machine as it has to work against resistance of the Leadnuts/belts, wheels, inertia, weight etc. Just know its there... If its under powered it will stall out when you work. Adjust it up a little. Or if its too high the drivers will overheat, shutdown and throw a nice red Exclamation mark LED on the front
