    Proximity switch Mach 3 Ess Smooth stepper

    I just replaced mechanical touch switches with Proximity switches and when triggered the led at the switch lights up but the diagnostic page in Mach does not trigger. 5v 12mm switch 4mm activation distance 300 mA Voltage on signal wire is 4.75V at rest and 2.5v triggered. I am thinking the differential is not far enough apart , especially on the low end. This morning I read about an ESS data Monitoring screen. Where would i find this and is it a fix to show the signal.? Please help , I am manually homing the machine and running without switches and would prefer otherwise. Thanks in advance

    What kind of a breakout board are you using? Does it have pull-up resistors on the inputs? If so, what is the resistor value and the rail voltage?
