    Hi everyone

    I finished building my MPCNC    Bought the Mini Rambo 1.3  and LCD on AMAZON  since V1 was out of stock a few weeks back

    So I connect everything with wires bought from V1.  flashed the board with the marlin version from V1

    And to my surprise I have a grinding sound on the Z axis.      X and Y work well with the same settings.  I tried everything I read about checking the wires , changing to a new motor.       I swapped the wiring and motor from the X axis with no change.  Still grinds on the Z even when the motor runs free.

    It all points to the board…. or some mystery setting in Marlin (I’m stuck here)

    Anybody have Ideas

    I joined my Marlin files as attachements and pics of my motor and LCD (which turn’s on but nothing appears on it)

    Need help

    You have a fake mini rambo, I am not sure what is different about them but they currently do not work with my firmware. when someone figures it out that owns on I will post settings somewhere.

    I know someone got one working but I can’t find the thread now. It might be as simple as swapping wires on the funky axis (Bill suggested this in another thread).
