Hi Paul a good tip for that on a customers one off item is test it using the gravoply setting and lay a scrap of clear Perspex over the item. That’s better than tape and you then have an exact preview of engraving. Also for positioning on Corel just put item in machine use keypad on machine to move head to place led dot in centre of the item look at the x and y coordinates and place the item on Corel screen in the same coordinates. I will pop some Perspex scraps in the post on Monday for you.
