 reuelt, here's some photos of the  STB4100.  It's located at the back of the controller box and is hard to photograph.

You board has ONLY 4 inputs.
One input (pin 1) must be used for E-stop

Would you sacrifice the use the probe input (pin 4)  so that I can have 3 separate X Y Z limit switches?
If so follow attachment for wiring.
If not you have to combine all X Y Z 6 switches in series into 1 input say pin 2.
