I've just purchased 6 of these for my limit switches and having a hard time getting them to work. I'm no master of Mach 3 but believe it's set correct in the pins to work with the current wiring into the breakout board.

As I'm just trying to get them to work I've got one wired in to the Z axis limit switch, and the power to the 24V outlet from the BOB but likely to use the stepper drivers PSU once working.

So wiring I've got is pin 15 Z-axis and then pin 15 set to the X++ limit. Detects nothing nor does the LED on the switch light up.
