Another point about these BoBs (for which documentation is very scarce) is that the logic inputs have an opto isolator with a 1k resistor connected to the +ve supply, the 12V one not 5V, and expect to see an "open collector" drive such as a microswitch pulling to Gnd or an open-collector output ditto. Caught me out and I had to convert a couple of sensors that generated a 5v logic signal.

Can you suggest, based on what you've seen, which pins etc I might try to get the spindle to work?
