I don’t have a final project to share yet, so this will be brief. I want to make something with the look of torched wood, where you use a blowtorch to burn the surface of the wood.
Alas, I don’t have a blowtorch, and probably shouldn’t be trusted around one anyway.
Luckily, the Glowforge can torch wood! Remove the lens and you can torch the surface of some wood with the full width of your ~2mm wide unfocused laser beam. Engraving a rectangle at 1000 speed, 100 power, 35 LPI provided full coverage. This box lid I tested on, which I believe is pine, took only about 2 minutes to engrave at such low LPI.
There’s no depth to the “engraving”, it’s just browned the wood as if I’d used a torch.
