EMC has been able to do this just about forever - in fact you don't even need limit switches, all you need is a home switch. It's called "soft limits". If your machine has hard limits (either switches or hard stops) at say -0.100 and +12.000 inches from the home switch, you should set your soft limits in the ini file at something like -0.090 and +11.090. Then, once you are homed, EMC will NOT ALLOW you to run past those limits. Of course, before you home, you can run into the hard limits - that is why you should train yourself to home all axes as the very first step after turning the machine on. If you _don't_ have a home switch, then of course this approach won't work. If you have limit switches but no home switch, then home to a limit (EMC can do that). If you don't have _any_ switches, then you are out of luck - but that's not what the original question was about.
