    The image below show the panel in place. You can see that input 3 is active due to the touch probe being plugged in. Note that the probe in connected to input 4 and and is not active.



    My next project on the mill is to install a power drawbar.

    Cheers,

    Peter

    One other thing I did to disable the spindle when the probe is plugged in was to process input 3 that is indicating the phono jack is plugged in to input 4.

    I modified the M3 and M4 macros in Mach3 to check the status of input 3. The modified macros are below;

    M3 macro
    Code:
    If (Not IsActive(INPUT3)) Then
    	DoSpinCW()
    else
    	Message "Probe is plugged in"
    	DoOEMButton(1021)
    end if
    M4 macro
    Code:
    If (Not IsActive(INPUT3)) Then
    	DoSpinCCW()
    else
    	Message "Probe is plugged in"
    	DoOEMButton(1021)
    end if
    I also changed the the button script for the spindle toggle button on the Mach3 pages that uses the button to the following;
    Code:
    If (Not IsActive(INPUT3)) Then	DoOEMButton(110)
    Else
    	Message "Probe is plugged in"
    	DoOEMButton(1021)
    End If
    BTW OEMButton 1021 is the reset button, causing Mach3 to go into reset if an attempt to run the spindle when the probe is plugged in.

    Cheers,

    Peter

    Nice job, Peter!
    A lazy man does it twice.
