My apologies if this has been mentioned before.
When you unbox your Glowforge, the instructions on the Forge direct you to setup.glowforge.com. On that page the FIRST thing you are told to do is turn it on.
If you followed those directions, the packing materials and shipping stays are still in place!
I’m assuming it’s good practice to remove those materials before flipping the switch.
There should be a link on that first page for the unboxing directions. I couldn’t find mine, and had to follow a YouTube video I found.
