Huge shout out to ryanjpedersen and his post years ago that inspired me to use my wifes Glowforge to start some of my own little projects. I’d link to it but new users can only put 3 links up I’ll post a reply with his original work.
Mistakes were made… I had to print that map maybe 5 times before getting the settings right, and even now some tweaking is needed to pull out even more definition of the height map. I also drank some whiskey and made the original holes the wrong size, requiring more print attempts. Learning curve using Illustrator for the first time, that took some time as well. But now that I have down the basics I should be able to do them pretty effortlessly from here on out.
