    Help required to adjust marlin pins.h

    Hi guys, this is my first post here as i have been finding difficulty researching my problem online.

    I believe my ramps 1.4 X motor pins or stepper driver pins are damaged as they have stopped working. I would like to re allocate these to the E1 location to by pass the problem but I have been struggling to find the information online.

    Is it as simple as changing the X pin values for the E1 pin values below.

    (current pins.h)
    #define X_STEP_PIN 54
    #define X_DIR_PIN 55
    #define X_ENABLE_PIN 38
    #define X_MIN_PIN 3
    #define X_MAX_PIN 2


    #define Y_STEP_PIN 60
    #define Y_DIR_PIN 61
    #define Y_ENABLE_PIN 56
    #define Y_MIN_PIN 14
    #define Y_MAX_PIN 15


    #define Z_STEP_PIN 46
    #define Z_DIR_PIN 48
    #define Z_ENABLE_PIN 62
    #define Z_MIN_PIN 18
    #define Z_MAX_PIN 19


    #define Z2_STEP_PIN 36
    #define Z2_DIR_PIN 34
    #define Z2_ENABLE_PIN 30

    #define E0_STEP_PIN 26
    #define E0_DIR_PIN 28
    #define E0_ENABLE_PIN 24


    #define E1_STEP_PIN 36
    #define E1_DIR_PIN 34
    #define E1_ENABLE_PIN 30

    //Should my new X pin values be :

    #define X_STEP_PIN 36
    #define X_DIR_PIN 34
    #define X_ENABLE_PIN 30
    #define X_MIN_PIN 3
    #define X_MAX_PIN 2

    Yes, that should work. Don't forget to comment the existing E1 pin defines so that the pins aren't allocated twice. You already have another stepper driver at the E1 position?
