Hello Shadi

I'm not sure how Mach handles this, but I do know that EMC2 has a very
configurable homing system, which does exactly what you want. In fact,
it may do more than you want ;) There's information on homing
configuration here
<http://www.linuxcnc.org/docs/html/config/ini_homing/ini_homing.html>.
