I can't say it would be a bad idea to use on the computer so you don't lose data during an unscheduled shutdown. However, the output of most household-variety UPSs is pretty limited and probably won't support the load of a spindle motor.

Is it a good idea or bad idea to use an uninteruptable powersupply on a CNC router system?

Sorry, did not think about spindle. I was not planning on using it on the spindle, just stepper motors and drivers.
Just to play devil's advocate... if you lose power, and the spindles stop, but your servos keep going... isn't that a Very Bad Thing? ;-)
Just an idea, but he could use a relay inline with one of his limit switches. This relay would be a normally Closed relay. Hook the relay up so when the alarm of the UPS goes off it picks up the relay and 'trips' a limit switch thus stopping the steppers while still allowing him to keep the break out board and such on his UPS.Originally Posted by neutronics
