I am a teacher that uses a Glowforge in my classroom, for various projects. One of my students has come to me with a wooden electric guitar body, painted fire-engine red in what I assume to be epoxy paint (very smooth and high-gloss) that she wants to engrave.
Can anyone give me some insight into what settings I should use for this? I don’t want to mess up her guitar, but would like for her to be able to do this, if it can be done.
If the guitar is standard size, it may not fit in the Glowforge for engraving. Even if it does, however, you should never cut/engrave any material without knowing for certain that it is laser safe. Cutting unsafe materials can be damaging to human lungs and machine electronics.
