Re: Limit switch problems..observations

Hello,

Caudlet, I agree with nearly everything you wrote...

But some additional physics might be worth observing. A spinning
cutter, engaged in material, is an accident waiting to happen if
cutting the power allows it to backfeed, even while it spins down...

A broken cutter is likely, and like so many accidents, the secondary
result can be worse than the "caused it" problem...

Killing power is not always the best estop. Be sure to COMPLETELY
think through the results of an estop, given the SPECIFIC machine
setup.

Hope this helps,

Ballendo

P.S. What's safe for steppers is not the same as what is safe for
servos, and vice versa.
