This has been going on a while and until now I have been blaming myself. After making my reference marks and making my mortise my joint matchups are off a 32nd or so (see picture) I think this is a scale zeroing problem, but I don't want to adjust something and end up down a rabbit hole. I started making this tray today and all 4 of my joints, single domino, were off the same amount. What needs to be adjusted or do I need to get better glasses. Thanks in advance.
