Thats your problem. (it should be off)

You have a short circuit between your pin 10 and ground.

ok it will take me some time to fix this; my computer & screen sits on top of my control box and to open the box I have to disconnect / remove the computer.

I will check the connections and when I will try again.

Do I leave the code you provided or use the original code

I dont see any problem on the connections but between the GND and pin 10 I have this capacitor I was told to put

How about if I change the active low status?

If you touch the plate and the LED goes out then active state is wrong.

I did touch the plate with the alligator clip but the LED stayed ON

Also checking the volts between the plate and alligator clip is 0

One end of the Red wire is connected to the 1/8 aluminum plate and the other end is connected to pin 10 on the BOB

One end of the black wire is connected to the alligator clip and the other end is connected to the GND on the BOB

Try connecting one clip directly to the tool and the other to the thickness plate

If your machine is like mine, spindle is electrically isolated (don't know why, depend on the mechanic)

One end of wire to the cutter,  the other to the ground from the BOB

The other wire, one end to the thickness plate, other end to input pin of the BOB

Be sure that the input pin is configured in port and pin
