I am curious to see how you generated the g code!

True, you also have to take into account the difference in depth related to the next curve, or you end up milling parts away which you don't want to be gone (like in this sample in the top middle/ slightly to the right).

Yeah the v-bit engraving is a cool feature, also for getting a nicer finishing when milling objects that isn't text.

I have an idea on my to do list to try and make (or convert) a font which is millable in one go. So you go over every line just one time but with changing depths making it fast. Like calligraphy where you use pressure to control the thickness of your line.

Nice! The V-bits look tricky to program in terms of predicting exactly what material will get removed. I guess you could work out maximum spacing of curves for a given cutter diameter?

I saw a nice use of a V-bit recently for machining text... normally you get left with cutter rads in the corner of machined pockets and this can make text look a bit clunky. Using a V-bit and raising it at the corners leaves a progressively smaller radius as the bit is raised so you get nice sharp text that almost looks like its been cut by hand with a chisel, only neat!
