Active high or low stepper is drive dependant (high=motor winding on or low=motor winding on.).
If your home is actually on the switch you can put the logic in the LIMITS.FIL.
Anytime a limit or home switch is triggered the LIMITS.FIL is ran.
If your home is not on the switch you can use ISTHERE logic in the commands G00, G01, JOG.FIL, ect...
