Just off the top of my head, I see a problem. The copper is not "even" on top of the clad. If you look at it with a magnifier, you will see low spots and high spots. Even with varying feedrates you will get burn marks in the substrate wherever there is a low spot in the copper. I could be wrong about this as it is theory and not actual practice, but if I am, could you please post a URL showing the project? I would also like to see more on this. -Mike
