My partner is a professor of ancient philosophy. We were trying to think of a joint project combining his work in Philosophy and my Glowforge. We came up with #gnomelithic.
He is translating thoughts of Ancient Greek philosophers, and I am engraving them onto rocks and leaving the engraved rocks out for folks to find when we go out for walks.
Thanks @cmreeder for the settings (Settings for Gravel )! I ended up using 300 speed and 100 power for engravings. Quality depends on composition, flatness, and color of each rock. Rocks are found in my yard.
