Re: Power Brownouts

I would try to find a UPS that has some sort of output that detects a
low line power condition. Then hook up the low line power fault to E-
stop circuitry on your CNC software.

The UPS could power your computer while you either save your work or
wait for the power to come back on.

a power failure when part way through a machining cycle. A UPS is
practical for the computer itself but the high cost of a very large
unit to accomodate the routers (and dust collectors) isnt practical.
