Re: The 250 byte packet viz. ESTOP

Del,

Great post.

(But sometimes the tooling into part scenario IS an emergency also.)

Total agreement with your main point that emergency's do not require
remembering machine position. They require failsafe and speed of
doing so.

something is going wrong enough that I feel it's an emergency to
stop the machine, who cares if the machine knows where it is, if I'm
about to lose a body part, the time it takes to reset up a wasted
part is worth it. If you are only about to crash the head or the
tooling into a part, then that really isnt an emergancy. And a
regular stop should be used. An E-Stop should bring the machine to
a halt immediately, it not sooner in the case of personal injury. To
hell with the machine knowing where it is in relationship to the
part.
