Where's the cheapest place to buy a Kress 1050?

A secondary emergency stop button?

Maybe a dead mans handle style one so all you've got to do is drop it as you run away :-)

Good idea.

Jonathan on a machine your size you just need an EStop on every corner. Hitting the button should cut power to everything except the PC and you should not rely on the PC to do this it should be hardware based.
