    Hi all can someone help me please

    I have a 3018 CNC machine with a Woodpecker Ver 3.4 board fitted. I have setup the home micro switches normally open and the settings in GRBL 1.1f are :-

    $20=0

    $21=1

    $22=1

    $23=1

    $24=25

    $25=500

    $25=250

    $27=2

    If I manually test the switches they all give the following error message :-

    Alarm 1

    MSG; reset to continue

    MSG;$H $X to unlock

    MSG Caution; unlocked

    Alarm1

    MSG Reset o continue

    So I know each switch is working.



    When you press home the Z axis drives to the limit switch at the top of the travel and keeps driving as though there is no switch.

    Just noticed the switches work as i said and i can watch them in the command window but they do not show in the pins window as the probe one does. I am using the GRBL Panel.

    Can someone help please.

    Hi All Solved
    The new Woodpecker 3,4 ver board has the Z and X reversed on the board. Swapped the connections and now all works fine.
