Hi everyone, Completely new this. I am currently building (or at least trying to) a pen plotter using the ACRO system utilising an Arduino UNO + CNC Shield. I've managed to get things to work for the most part with the exception of the Xtension Limit Switches that come included. Could anyone point me to a wiring diagram that would help me to get these to work with the CNC shield? Any pointers would be greatly appreciated! Many thanks!
If you are using a cheap Chinese knock-off CNC shield, the pinout for GRBL 0.9 and up is wrong for one of the limit switches. See the gnea GRBL wiki for help.
