I found some spare glass tiles that I had leftover from a kitchen backsplash - and decided to test the Glowforge on them.
I cleaned up some r2-d2 fan art and attempted an engrave. I was extra cautious on the settings. I masked the whole piece with blue painters tape. I microwaved the tile for 2m on medium. I did not coat with dishwashing liquid since I had the tape. (I’ll try it that way next time).
Settings were 495/40 min 5, 2 passes.
It came out pretty good. In indirect light it doesn’t look super impressive because the lines look fuzzy - because of the blurred shadow on the surface behind it.
In direct light (at an angle) it looks pretty amazing - especially the crisp shadow on the back surface.
