    I have wired in 2X Proximity sensors on the X axis on my cnc. Ebay Item 32113180610
    I am using a USB BOB (Ebay Item number 26116368592)

    The normal micro switches I have on Y and Z axis work fine, but I want to use Proximity switches for X, as they will get splashed with liquids.

    I have used the BOB DC +5V supply to power the P switches (as it states on the specs 5-24V). I have tested the output of both the switches which is again 5V DC. Plus the LED on the switches light up when metal is passed over the sensor part *all good so far*. But the BOB does not light up its input LED's, Nor does Mach3 diagnostics recognise that there is anything connected to these pins (14 / 15). I have tryed swapping to other input pins, and all the ports and pins settings in Mach3 are correct.

    Any Ideas ?
