    Smile my stepper motor NEMA 23 do not move but make a little noise

    Hello everybody
    My project is a large 3D printer. I understand the CNC zone is about CNC (logic ), but the electronics and motors are very similar between my 3D printer and a CNC (I need powerful motors).

    ELECTRONICS
    ARDUINO Mega 2560 + RAMPS 1.4 + power supply 12V
    DM 5042 external driver + Power supply 36V + NEMA 23 stepper motor

    SOFTWARE
    Repetier Host to communicate with the Ramps
    ARDUINO to upload the firmware (Marlin)

    TROUBLE
    the motor NEMA 23 reacts when the ARDUINO board receives a command … but not as expected : indeed, it makes a little noise like a "zzzzzzzzzzzzzzzzzzz" instead of moving normally (in other words, the axis of the motor does not turn on itself).
    I checked several times the connections, components …etc. It seems to be fine.

    I do not understand where the trouble comes from.

    Anyone can help me ?
    Thank you very much in advance

    best regards
    Fab

    if motor acts like this it ususally means that You ar using to high frequency and motor doesn't have time to execute the steps.
