Using Max Z Endstop as a Backup
I'm leveling my Bad with a BLTouch (ZMin) and I want to use a Max Endstop as a Backup because if I print something that is near my max Z and I turn the printer off the next time I turn it on and home the axes the bad goes down and hits the ground. I already tried just connecting an Endstop and I configured it as one in the firmware but it just gets ignored. Do I need to configure something else? Also is there a way to add a physical button for the "NOT-STOPP" feature?
