The same number means different things

Both grinders use a numbered dial, which makes it tempting to copy a number straight across. Setting 30 sits at grind index 15 on the DF64 Gen 2 but 51.5 on the Lagom P64 — 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 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.

Dialing in the Lagom P64

A single-dose flat-burr grinder built around burr swapping — the character changes substantially with the set you fit, so treat published numbers as approximate across different burrs. Stepless, so the settings below are targets.
