[QUOTE=magicniner;65341]You can use an engraving spindle which takes a Gravograph nose and allows cutting depth to be set by the amount of cutter protrusion, a nose with a pivoting ball with through hole for the cutter allows engraving over 10 degrees either way around a 20mm cylinder with a 2D engraving.

That only works fine for 2D engraving if everything is to be engraved at the same depth. G.
