3.6 Connecting BlackBox 4X to a Door Sensor (Machine Enclosures) (Advanced)

OpenBuilds BlackBox supports the door-ajar detection features available in Grbl. In order to activate this feature, ensure you run the custom compiled version of Grbl that has this feature enabled. It is not available in the default Grbl configuration.

Note: This is an advanced feature, specific to machines with an enclosure, and not required for everyday use.
