A tip that TSO did not mention in their instruction... I had to add 1/6" veneer to the fence (see dark color veneer) so now the fence face lines up exactly with the indent on the side of the domino which indicates the center of the bit. (My finger is pointing to the indent) Now I can put the fence on the line where I want to center the domino's.
Perhaps you did that? Not sure. I got that tip from a festool video.
