New question about limit and home switches

Hi everybody,

I have a question about home and limit switches, and EMC. Let's say I
have a machine with a 12 x 15 table. I want home to be the center if
the table. The machine has limit switches on each axis and a home
switch on the x and y axis positioned so that the table is centered
when the home switches are tripped. The question is, what does EMC do
if a home switch is tripped during a movement such that x would move
from -4 to +4 and trip the home switch when it passes 0? The
following code may help explain this:

g0 x0 Machines is at home.
g0 x-4
g1 x4 Machine being directed to move 8 units from -4 to +4

The g1 x4 movement will pass through the home postion and trip the
home switch. Will this cause problems with EMC?
