Javier,
Welcome to EMC2
my machine uses "proximity" switches as
home and limit switches.
However during homing i also use my encoder
index pulse to nail down my home position.
the emc handbook esplains how to enable the "use index"
for homing. (and other neat homing stuff)
If you are using steppers, you probably do not have shaft encoders.
but you could always just hook up an encoder per axis and just use the
index pulse output to find home..
i agree that the switch only homing probably does not always
get back to home as accurately as the "home swtch then find index pulse"
setup, or at the least it should be much closer, consistantly.
Linux rocks....doze blows...

Subject: [Emc-users] HOME Sensors
I'm not sure if this is the correct place to ask about this :( I
have no idea of the type of sensors that are used for HOMING, I'm
using magnetic presence relays from Omrom, that came with the linear
guide I'm using, but I think that precision is a must for a home
sensor (at least it is for my application), so: Can you
point me to specific HOME sensors/relay with precision / machining in
mind? (brands, or type) Thanks in advance Javier
