It is very interesting. Is the Black printed by Dual-Color Extruder or is it a half circle hole that you fill in black paint?

yeah, sorry this isn't clear. It's a special sign making plastic which has a very thin top layer of one colour, and a base of a different colour. This is a white top with a black base. It gives a super crisp result. I know people who've done similar on painted wood and that can work too.

Thanks for your reply, so your g-code is for CNC router?

yes, it just generates drill commands g81 or g83
