Solved Failed to enable endstop error using BL Touch
-
Hello, I am using a BL Touch on my Ender 5 Plus. When I home the Z-Axis, the bed moves up but then stops and the printer says failed to enable endstop. How do I fix this. The BL Touch is wired properly and it goes through its start-up procedure.

@tratoon a BLTouch is a Z probe, not an endstop. Homing Z using a Z probe is done differently (using a G30 command) compared to homing using an endstop. See https://docs.duet3d.com/User_manual/Machine_configuration/Configuration_cartesian#homing-z.

@dc42 I fixed it, the code the RepRap Config Tool Generated was incorrect. I had to dig around for the correct code.
