A bit of assistance please

I am attempting to cut a 15” radius circular piece of pine. I have set my work space to 15X15 but it’s not centering the work. Any suggestions that doesn’t include shifting the image as the defeats the purpose of the @center in material” option. Thanks gang!

Not centering in the preview or on your actual workpiece?
What is the actual size of your workpiece? How are you setting work zero?
Is this all done in Easel? Can you share the project?
File–>share–>share with link–>Save
Also a circle with a 15" radius won’t fit on a 15" square. I’m guessing you meant diameter, but I don’t want to miss something.

Put the center of your material at 0,0 in Easel. It will allow carving outside the normal grid you see on-screen.
