docs_blackbox x32_connect door sensor
OpenBuilds BlackBox supports the door-ajar detection features available in Grbl. In order to activate this feature, ensure you run a custom compiled version of GrblHAL 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.
- Open the door to pause (and optionally park)
- Close the door to take grbl/grblHAL out of DOOR mode. It stays paused until you send a resume command using your controller.
- Go to OpenBuilds CONTROL > Wizards and Tools > Firmware Flashing tool > BlackBox X32 tab > Select "2/3 Axes CNC/Laser: Dual-Y with Door Switch" > Flash
