But you would be daisy chaining two surge suppression systems. I know you are thinking of people daisy chaining two surge strips so they end up with double the plugs, but that is only one instance. In the case you are talking about, you have one surge suppression filter in the surge strip and one in the Glowforge, so you have two surge systems daisy chained together. And supposedly the one in the GF is better than what most surge strips will have.
The fire in my office that I mentioned earlier wasn’t because my co-worker had 11 items pugged into the two surge strips. My co-worker had connected two surge strips together so the 2nd one was within range of his laptop and monitor cords. (I think he had a calculator plugged into the last one too), but there was nothing but the 2nd strip plugged into the first.
The two surge systems will end up confusing each other causing you to loose the protection you want. When you turn on the GF, it’s going to trigger the surge suppression in the strip, which will trigger the surge suppression in the GF.
If you want to try an experiment, try hooking a UPS into a surge strip and only plug a desktop computer into the UPS. Start the desktop computer. You will hear the UPS clicking on and off a few times because the surge strip is confusing the UPS’s own protection system.
There are sure suppression systems built into copiers and most laser printers too. (not the really cheap laser printers). They build them internally to keep the average user from not using it. If the average user can remove it, they will, so build it internally.
The first thing Glowforge support asks when troubleshooting is if you have your equipment plugged into a surge strip or extension cord and if so, to remove them.
There have been a few reports of weird behavior with surge strips (this was someone who had the GF plugged into a cheap 6 outlet expansion plug) Weird behavior at start-up (new GF)? and one person whose Glowforge died and it was suspected it was due to an issue with the UPS it was plugged into.
And this post from Dan: Don't use a UPS? He says they have only successfully used the Glowforge with $2,000 UPS. He also said if there is an electrical related damages to the laser, the GF warranty will not cover repairs if your device was plugged into a UPS or surge strip.
You’ve seen this in the manual and had several people tell you similar information, but it appears you are determined to add one, so I’ll finish with this — it’s your device and you can do whatever you want to it, but don’t get upset if Glowforge won’t honor the warranty if something happens.
