Good call on the border. I have the corner framing pieces for lining up the component side print. I got it to work with my weird thick-inkjet-paper-through-a-laser-printer approach from 10 years ago. Here's hoping it still works. I may end up drilling a couple of the holes to be the witness mark(s).
I didn't take any chances. Went with 600mm/m at 100% so it was like 1 hr 45 min total, but it's in the background. I might could go faster. Maybe I'll try 1000mm/m next time. There has to be some sort of "it'll move that slowly only when the laser fires" but maybe it's not that much difference. Or at least maybe I could see if I could do the second pass a bit faster
The cross hatching made all the difference, I think. it's just not precision this hobby laser and going in the perpendicular made sure if there was any missed paint the lines at least wouldn't be contiguous.

after my dremel died I gave away the drill press meant for it. Didn't really need another dremel at the time. Maybe it's an excuse to go get a harbor freight drill press… not that my garage can hold much more junk.
When I bought bits way back they thankfully came in like a little tube of 10x. broke nearly half of them doing my first project, too. I had to go super slow was my memory. It's been quite a while since I drilled.
But we are drilling metal through suspended bits of glass. Not sure anything that small is going to keep its edge with that. I inherited a bit sharpener, but it doesn't go down that small, sadly.
aside: The thing I never understood (in the kitchen) was GLASS cutting boards. Like, do you hate yourself? Did someone who owned stock in every knife sharpening and cutler biz invent the glass board?? It's like instant edge death.
