Homing with Black Box

Describe your issues please? Same, isn't always same, subtle clues in your own problem description usually helps find the real cause to your issue.

Usually wiring related, check that you don't have the wrong switch plugged into the wrong port, and that your wiring matches docs.openbuilds.com/blackbox

 

Don't feel silly! It happens to all of us at some point - been there, done that myself
