Yeah for newer versions of Illustrator the correct settings look like this:
Just one thing…You don’t actually have a full 12" x 12", you have 19.4" x 10.95" for cutting, and less than that for engraving. (You are limited by how far the head can reach.) But in any case, you’re limited to slightly less than 11 inches tall, not 12 inches.
When I design anything in AI, I make sure it will fit on a 19.4" x 10.9" space. I still use a 12" x 20" artboard though, because if you set your artboard to that exact measurement, it will not resize the design. Even if you have goofed up the settings on the SVG save.
And last point…this is how the screen you see works…part of the wood on the bed is hidden by an overlay. If you want to maximize full use of a sheet of material, use the origin point at the lower right corner of the grid (black star) and build out from there. There will always be an uncut border at the left side and the top of a sheet of proofgrade material.
