How deep should the router be set to make 1/4", Half-Blind Dovetails?

Using a 7ยบ dovetail bit, set the router bit depth of cut to 5/8". Make a test joint, then adjust depth of cut as necessary to achieve desired joint fit. If joint is too loose: slightly increase depth of cut, if joint is tight: slightly decrease depth of cut. Make another test joint and readjust as needed. This adjustment is sensitive, make changes in very small increments.
