You must have software limits set to some modest number, and no 
home switches, so you don't home to a predictable location.
You can always set home in about the same place and set limits 
relative to that, or set the software limits to + and - each 
greater than the full travel of that axis.  That way, no matter 
where you set as home, you can't exceed the soft limits.

There are significant advantages to putting in home switches. 
It seems to prevent losing your axis alignment when you have to 
abort programs, for instance.  Maybe homing anywhere provides 
the same benefit, as long as the homed symbol shows up.
