Sychronizing 2 motors?

Hmmmm
Does anybody know how to solve the following problem.
I am building a flatbed router with 2 motors driving the x axis.
how do i synchronize the two motors when homeing the x axis
i know this can be done through the software ie,

send both motors home
when motor 1 reaches switch then stop
until motor 2 reaches home then stop
the two motors (axis) would be in the same position.

the problem with this is it has to be written into the
software,because as far as i can see none of the popular progs has
this facility (emc,turbocnc,master5).

or is their another way round this ie via electronics

thanx
