I thought about that, but if you look at the piece of wood, it was the remainder of a piece, so there was maybe 1/4" around the sides, so likely would have curled around anyway.
That’s what this was a test for. Having been burned by curling acrylic (ha, see what I did there) when acrylic curled on me in Clifford I figured hey, let’s try this in wood first…
Now any experts out there on acrylic know, if I do this kind of thing on acrylic, can I hold down the edges firmly (say strong neodymium magnets) and prevent this?
Also @Dan, can I set a precise depth to engrave down to? I need to go down 0.5mm (it’s a cool project that I need an insanely precise mold for).
