Uninterruptible Power Supply (UPS)

Do you know what is a REALLY good idea to have when your neighborhood has occasional brownouts?

Take a guess.

Do you know what helps protect your 3D printer and octoprint server from someone accidentally flipping the wrong light switch?

Go ahead, guess.

Do you know what helps you connect to the rest of your network so you can hurriedly shut things down when you have a neighborhood power outage?

Guess yet?

Did you guess a UPS? Good for you! You got it!

Yes, after too many close calls and losing 8 hours on a 12hr print, I’ve finally put the Snapmaker on a UPS, as well as the router, web server, and cable modem.

Now, I know that in all likelihood, if there’s a neighborhood outage the cable line will lose power too, so I’m really not betting on having 30min of internet access while waiting for the power to come back on. (though that would be pretty cool)

To Do:
some sort of monitoring on the big ups downstairs that will tell the two PIs to shut down 15 min after the power goes out so I don’t have to scramble in the middle of the night.
