Thomas,
I use the same sensor for home and limit.
On my CNC router, I very seldom home my machine. I just position the router
to where I want my 0,0,0 point to be and do a G92 type command.
The limits take care of over travel.

Thanks Bob. Nothing for Home or do you use the same sensors for limit and
home?

Thomas,
I use one limit sensor on my Z axis, two on my X axis and one on my Y
axis
with two targets.
