 In the case that the sensor is outside of the plate after homing the Y and X axis, use Z safe homing (applies if you are using a sensor support with a negative Y-offset:

 For ABL to work correctly it is **essential** that the printer knows the exact offset from the nozzle to the probe, otherwise any correction is not going to be applied in the right place, and it may look like the printer isn't correcting at all.
-If you downloaded SkyNet3D and used one of the example configurations, it probably came with some pre-configured probe offsets and a recommended sensor mount for you to print.  It is absolutely vital that you check the sensor offsets once your probe is installed, and update the values in configuration.h accordingly.
