Where do I connect the endstops (Limit switches) on the GRBLshield v4?
Also – as far as config settings for it, do I need to change anything in the GRBLshield config menu (like the homing direction, max position, etc) or is it kinda like marlin (the reprap firmware) Where i have to hard-code it into the firmware sketch and re-upload it to the UNO?
Here’s the pinout that grbl uses. The limit switches are labeled. You can connect to the holes on the grblShield or solder in a header to bring them out.
