I'm probably being stupid here, but - I assume the relay is for switching the spindle on and off. At the moment I'm just getting my steppers to work, and testing with Linuxcnc and the stepconf wizard. All the steppers are working, but every time I click on "test this axis" the relay comes on, even before I jog the axis. Why is this? When using the machine for real, I would only want the relay to come on when I want the spindle on, not when moving an axis. I don't have the 24V supply connected atm, if that is relevant
