    Would help to know what alarm you get?

    Suspect gnea/grbl (Homing Pull Off) - set it to 10, reset board, try again. But depends greatly on which alarm code Grbl entered. When asking for support its always best to include screenshots of any alarms, errors, logs etc :)

    Thanks, again. I just signed up for this forum and was about to post this question. I am having this exact problem. I am just finishing up building my cnc router and need the limit switches to work correctly before I can run the homing and go live. I am a newbie with cnc and there is so much new that I am encountering; several problems have been solved with the correct config settings where I just didn’t understand the function. I had assumed my switches where too cheap and was just about to buy new/expensive ones and rewire. Much appreciated. I will start looking here first when I have an issue from now on.
