Close loop steppers

Hi,

I have presented a few ideas about a simple closed loop kind of
stepper system, - in my "crazy stuff" inputs. I have a few other
solutions, but would just like to hear if any found this
interesting at all, and if someone has some comments. My idea
was just some stupid simple solutions, better designs can be
made. It all depends if anyone think this could be of any help.
One of the things I had in mind with all of this, was just a
dissable function if the lost steps grew out of hand. But I don't
know how you opereate steppers. The way I have done it before, did
not involve any real variable added loads, from the tool. So I
just wonder.
