Hello again all... I'm trying to configure a touch plate probe to work with my standard Ox build and Xpro v2 Cnc controller. I have hard limit switches set up on x,y & z. I think I know how to initiate the probing command g38.2 cmd... But where on earth do I wire the probe wires to on the Xpro? Typically it would be pin A5 on an arduino... Baffled!
