Stan,

Keep in mind that killing the power to the motors (stepper or servo,
unless braked) will allow a presently cutting tool to climb,claw and
grab into whatever it can reach as the spindle(definitely hard-wired
to the estop) is winding down. Rack and pinion drive and Ballscrews
allow this to happen the most, followed by high lead leadscrews. Be
careful and THINK about what will happen when things are going badly,
You may not want to kill those motors until the spindle has stopped!
