Hi Recently I bought Openbuilds Xtension Limit switches to install them on my GRBL machine. Machine is based on Arduino ( to be more exactly to the Phoenix GRBL controller, which is one of incarnation of Arduino boards). I would like to get some help. First of all, as I am reading in internet , all sources recommend to use normally closed switches in CNC machines, saying that in that case there is a little bit more safety. I can make the Xtension Limit switche as NC, but seems I will loose the noise reduction in that case. Can anybody help me with the wiring diagram of Openbuilds Xtension Limit switches to regular Adruino board ( not Black box !) Thank You in advance David
SIG to the signal pin GND to GND V+ to 5V No need, Xtension limits have onboard RC filters, and the Grbl default settings work with NO switches
