Hi all, I’m new to working with Aduino and Grbl. My question is: I have an Arduino Uno and CNC Shield,
I have flashed the Arduino with the v0.8 Grbl. I have tried to set up my end stops but I get no light when I push the switch. On the CNC board on the right side- white and black pins Y+ Y- X+ X-. I have the black wire going to the black pin and the green wire going to the white pin. Do I need the red wire connected to the 5v pin to make the switches work?
I hope this is clear enough, Thabk You for the help.
