Another Large Burn Question

I am making a plaque that is 54 inches long. My shapeoko is 33X33, I have watched the video several times with the mermaid. I can cut the shapes, no problem, make the registration marks all good, set the first target and the second target good (as indicated by the blue square. The next step is where I am going wrong. When I do the frame, it is nowhere close, So what I am trying to say is the 2nd burn does not start close to the registration points. The other funny thing is that it does not start burning the side where the other one started it begins at the far end, so I have to wait for the entire burn to see if it lines up. Not sure they are related.

thanks in advance for any help
