just how important is repeatability on your home switches? i guess if you were using a true fixture and running several copies of a part over the course of several start up cycles, then maby.. but for the average home user, just being able to home the machine within a few thou would would seem to be good enough for me.. cause i'm gonna manually jog over to my work anyway and re-zero there...
