I have my homebrew diy cnc machine running a code through Grblgru and am happy with it so far.
I am using a mega 2560 with ramps 1.4 board but cannot get the limit switches to work.
I have a 3d printer as well so I know how to connect X, Y, and Z limit switches to the board but the grbl wont react when I toggle the switches.
I have tried both min and max pins but no dice.
I know the switches work when I use pronterface and Marlin but would like to have them connected with grbl.
Any help appreciated.
