Hi, I bought 6 of the OpenBuilds Xtension Limit Switches and want to use them on a Centroid Acorn board-driven CNC. So I connect the V+ and Grnd, where do I connect the blue Sgnl wire?
Refer your controller's manual. V+ = power for signal pullup and filtering circuitry GND = Ground SIG = the endstop signal (Goes LOW [GND] when switch is triggered, otherwise pulled up to V+)
Thanks. Is there any way to alter the switches to be normally closed? I liked the noise filtering but would prefer NC, because NO means if the switch fails it won't be discovered until a crash.
