Ver 1.5.06 Centering Job

I created a box 9.0 tall and 8.5 wide and designated it as a tool frame and using Absolute Coords and snapping my art in the middle of the tool frame it burns to the right of center on the work piece. No idea why.
Any ideas appreciated.
I also home the laser to the work table and go from there. Its not off alot but enough to see it’s not centered.

Select your tool frame.

Press “P” to center that frame in your workspace.

Right click on the frame to lock it in place.

Select both your frame and the object, then click on the image tool button.

Now run your job.

Thanks for the help
