I got my GF 2 days ago, and it feels great to be posting on the “Made on a Glowforge” category.
Before getting to any of my own projects, my kids were jumping at me to make something for them. We made a quick puzzle out of proofgrade (I did not take a picture), but they wanted to explore the trace function even more.
I took out some craft foam I bought at Walmart. They have a sticky back to them, and are about 1mm in thickness. The come in a pack with about 10-20 different colors (they are 8.5 in by 5.5 in I think)
I engraved it at 1000 speed, 10 power, and cut it at 140 speed, 4 power, 2 passes. The width of the material was 0.04". They came out looking great.
