Yeah so… here’s a chunky 8mm machine screw countersunk into 1/4" acrylic.
Manual settings. One pass. 8mm is the only size screw I have laying around and the head is pretty much just as deep as the acrylic so I needed to go aggressive and engrave completely through. If I needed to do this again, I would step the speed up just a hair rather than reducing power, or reduce LPI from 340. This was an 8 minute engrave but most folks would usually be working with smaller hardware and thinner material which will take much less time.
In the close-up shot of the completed acrylic you can see what looks kinda like pixelation in the engrave… and that’s because it’s perfectly duplicating the gradient bitmap in the file. Wow!
