Above is my post on something similar. I’ve now done a few real carves and it’s worked. I had a circular piece of wood, marked my center point and set that as the home position. In Easel, once my design was imported/created, I selected all (Command + A on my mac) and then switched from the Cut to the Shape tab on the right, chose the center radius button and set the center to 0,0, which moved my entire design to be centered on the home position.
Also if you just need exact positioning, you can use that Shape tab and manually type in the location of your artwork, in reference to your home position
