Ok so I had to get another driver for my setup as X is mirrored on my new CNC design. So I decided to drive my Z axis with a Gecko G251X. Now I think I have it wired correct but I need advise about one connection.
On the PBX-RF there is an Enable pin. What do I connect the Enable pin to on my G251X? Only one I could think of is the Disable pin or that I don't need to connect it, but don't want to try until I get some input from those that know.

check with a voltmeter on the enable coming out of the BOB. If it is ground (0 volts) when E-stop is on, and floating or 5v? (maybe, not sure) when not in e-stop Then you could connect it to disable on the drivers.. You could always email the seller of the BOB. judging by the docs, im sure they get lots of emails.
