    Hi m_c


    from post 45 "John, I suspect you've got the optos in the wrong order"
    you are correct

    now I have looked more closely
    Click image for larger version.  Name: Limit Switch tester & partial TX14175 circuit.jpg  Views: 1044  Size: 355.5 KB  ID: 21359

    during the last few days I have installed mach3 on 3 PC's
    IBM thinkcentre , Dell optiplex 755 and a PC built using a ASUS H110M-R motherboard

    so I should be in a better position to test Kevins mach 3 settings
