I did a one-edge jig shown here (second pic, left edge):

Map on slate

A nearly maxed out engrave at 10.5” by 16+“ (18:12 aspect ratio), The map is of Strongsville Ohio from a map of Cuyahoga County in the library of Congress, circa 1858. A gift for some Ohio family members. [image] As always lighting matters, here it is in progress: [image] Thanks to @kittski for her mineral oil slate technique and @Jules for posting settings.

You should be able to easily achieve sub-millimeter precision with a jig like this.
