Hello NormanE,Since we don't know where everyone reading this tutorial is coming from (Mac? PC? Linux?), formatting the microSD card helps establish a baseline for the rest of the Instructable and make sure everyone gets the same results, as much as possible.It's also (absolutely) something we do out of habit.Thanks for your comment!

Hi peabody1929! It's a great suggestion - we will add it to the list of follow-up setups in the last step of the Instructable. Have a good day!

Hi there! We should absolutely have tried to make this pic bokehlicious on purpose - Thomas says he'll check some Instructables and try to make it happen. Have a good day!

True, or Ms. Pacman!

Thanks!

Sure PCB's can be sourced from many places, I choose these boards because of availability, sturdiness, and cool factor. A lot of modern/cheap boards are really thin and packed with components so they would be more work but a possibility.

Sure but will it have the retro Atari vibe? Could you say you're wearing space invaders?

We have a 40 Watt Epilog Laser. For anodized aluminum Epilog recommends at 400 DPI to engrave at 100% speed and 60% power. Higher resolution 500 DPI at 100% speed and 50% power.
