Re: [CAD_CAM_EDM_DRO] Re:Home Switches

After I replaced an encoder on my EZ-Trak, I heard something about
putting the home switch within a certain distance-angle of the encoder.
I never messed with this, maybe I was lucky. (It seems to home fine.)
Does anyone know about the relationship between the encoder angle and
the home switch? I assume it relates to the Z pulse (1 pulse per
revolution). Could it be related to the thread here?
