Now that my quill drive is up and running, and after putting it off for FAR too long, I'm finally going to start putting limit switches on my knee mill. But I'm not entirely clear on exactly how to set them up. On the quill in particular, I want to preserve as much usable travel as possible (since there's only 5-1/8" to begin with) between limits. So, my question is, how are limits normally setup? I can see a couple of different ways to do it:
1) Setup hardware limits so they trigger somewhere inside the "hard" limits, allowing perhaps 1/4" or so for a "safe" zone?
2) Setup hardware limits to they trigger *just* short of the "hard" limits, then use soft limits to create a "safe" zone.
I'm assuming the safe zone should, ideally, be just long enough to allow the axis to coast to a stop from a full rapid before hitting the hard stop.
Are there other options? How are limits normally setup and used?
