Cutting a non square or rectangle piece?

I have a large 15 in diameter circle piece of wood that I would like to use. My question is how do I set the zero or design in easel to make sure it carves correctly?

Center your carve in easel at the corner. When you do your setup in the carve section, just zero the xy in the center of your circle(mark this prior). You could use a v bit to get precise alignment if you need(align with v bit, set xy, change bits then zero Z) or eyeball it.

That makes sense. Guess I’ll play with it. I was try to carve out an inner circle and have some text in it and image.

Setting up a bump stop might be worthwhile. Comes in handy for all sorts of things?
