Hi everyone,
I have a 4 axis TB6600 controller



After configuring the Mach3 , I'm now able to control them ,
but I'm little bit struggling on connecting PnP sensors (proximity sensors) on the Controller and make the right configuration in the Mach3


I'm using this PnP model :



here is how its labeled :



I've connected the sensor with the controller Board as below



Blue wire on the Gnd , Brown on 5v , and the Black one on IN1 (or Blue wire on the 5v, Brown on Gnd , and the Black one on IN1) -> the sensor works fine in both of connections !! (red light turns on every time I put a peace of metal near to the sensor)


now I've tried to see what happened in the Mach3 when the red light turns on , but nothing happened
here is my configuration on the Mach3 :

I've followed this tutorial on youtube ( ), which allow us to detect the right pins to use automatically , but nothing changed


can anyone help me on this (is the problem in the wiring side or config side ?)
