Conical against flat — the Barista Express Impress (built-in)'s scale curves where the other runs straight. The Barista Express Impress (built-in) is numbered 1–25; the DF64 Gen 2 is numbered 0–90.

The same number means different things
Both grinders use a numbered dial, which makes it tempting to copy a number straight across. Setting 13 sits at grind index 36.3 on the Barista Express Impress (built-in) but 2.3 on the DF64 Gen 2 — far enough apart to change the cup.
Converting a setting
If a recipe quotes a setting for one of these grinders, read across for the equivalent on the other. Rows are spaced evenly by grind size, not by dial number — on a conical burr those are not the same thing.

The shape of each dial
Where the connectors bunch, that grinder’s dial is compressed and single steps count for more. Comparing the two shapes tells you which gives finer control, and where.

Dialing in the Barista Express Impress (built-in)
The Impress version adds assisted dosing and tamping, but the grinder underneath dials much like the standard Barista Express. Its range is built around espresso; treat filter settings as the far edge of what it was designed to do.
Dialing in the DF64 Gen 2
A 64mm flat-burr single-dose grinder that became popular precisely because it puts commercial burrs at a domestic price. Espresso is the design centre; the burr choice you fit matters more to grind character than the dial does.
