    For my sanity....

    Plug in the servo to EXP3 (hardware) pin6 and add the following to the pins.h file...
    #ifdef NUM_SERVOS
    #define SERVO0_PIN 5 // For RUMBA PWM_1 is to be used for the servo it is on Epansion slot 3, pin 5
    #endif[/i]

    Next I need to add uncomment the following in the config.h and insert some harmless numbers into the endstop values for the probe foot.
    #define NUM_SERVOS 1 // Servo index starts with 0 for M280 command

    #define SERVO_ENDSTOPS {-1, -1, 0} // Servo index for X, Y, Z. Disable with -1

    #define SERVO_ENDSTOP_ANGLES {0,0, 0,0, TBD,TBD} // X,Y,Z Axis Extend and Retract angles

    further up in the config.h uncomment the //to enable the ABL feature
    #define ENABLE_AUTO_BED_LEVELING // Delete the comment to enable (remove // at the start of the line)


    Change the value in the min_software_endstops to be false
    #define min_software_endstops false


    Change the travel speed to a move conservative value
    #define XY_TRAVEL_SPEED 4000


    Once all that is done I can start to test the feature and tweak my probe locations and enter the offsets...Does that about sum it up?
