Years ago there was a great MPCNC guilloché drag-engraving writeup (hard drive platter, diamond drag bit, 0.1 mm depth). I built a free browser tool that generates these patterns as SVG in true mm units, with a ring mask and cut-length / time estimates: guillochegenerator . com - should drop straight into EstlCAM/Lightburn.
If anyone runs one on brass or a platter, please post photos.
Oh that’s cool. Does the code only do that tiny depth or could it be applied to a textured bottom to pickets in say wood?
This is great! I think I’ll try it with some regular V-bit engraving on wood (don’t have a diamond drag bit).
It’s just generating a 2D SVG so I figure you could code that as a profile toolpath at any depth. Might need to scale the vectors though depending on material and bit.
Yep, the output is just a 2D SVG in real mm, depth is whatever you set in CAM. For wood I’d just scale the pattern up and widen the line spacing so it survives the grain.
Exactly. Just watch the depth with a V-bit — deeper cut = wider line, so tight patterns can merge. Post a photo if it works out!
That is so cool.
