I've been using my CNC Taig mill for a while now and I'm generally a happy camper. There is one thing I'd like to improve though. Occasionally I manage to stall the cutter (I really need to uprate the motor, and will go with Tony's suggestion of the Sherline motor).
What I'd *really* like though is a way to kill the power to the mill if the cutter stalls (i.e. the motor stops turning). I'd like to turn off the motor and the steppers. That way I could leave it chewing at a lump of stock and wander off with a slightly clearer mind to do other stuff.
I've got zero ability with circuit design (or, come to that, building). How feasible would it be to do something along these lines?
