the glowforge is a great tool. it always works the same way:
you carefully design your thing, you enter all the parameters for laser intensity, number of passes, and material width, then hit GO and it fails to do it properly

and the best part is that between every attempt, you have to go back and forth between the computer and the big laser box, which in my case is barely in the same building

max power level: fails to cut all the way through the very thin wood
max power level, half speed: cuts so hard that it snaps in two because it's too burnt

gotta slowly binary-search the correct power level while it takes 5 minutes for each iteration and a couple dollars of materials

Anyway I'm only slightly temped to use it to cut a floppy disk in half

I do want to use it for a floppy experiment: I want to try and laser a hole in the disc.
Then I'll go back and reformat the disk (using a flux imager) so that the hole ends up in the middle of a sector.
So then the sector will have random data when you read it, because there's no material there
