Home / Limit switches

List –

The current discussion on g-code and coordinate systems has me
wondering about what switches are really needed on the machine
axes. The typical setup sounds like 2 limit switches and a home
switch per axis. Why is the home switch necessary? Can’t you
just reference one of the limit switches and add ½ travel to get
to the center? That shouldn’t even be needed if you’re going to
just go and set your part origin somewhere else (so it seems).

Does anybody out there omit the home switch?
