Grind setting conversion
Eureka Mignon Libra vs Fellow Ode Gen 1
Two grinders cross-shopped at the same money. The Ode Gen 1 is numbered 1–11; the Mignon Libra turns 0–24 rotations.
| Mignon Libra | Ode Gen 1 | |
|---|---|---|
| Brand | Eureka | Fellow |
| Scale | Rotations | Numbered dial |
| Dial range | 0.0 rotations – 24.0 rotations | 1 – 11 |
| Burrs | Flat | Flat |
| Espresso → filter | 6.5 rotations | 1 numbers |
| Filter → coarse | 7 rotations | 9 numbers |
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 Mignon Libra
The Mignon with an integrated scale, grinding by weight rather than time. The dial behaves like the rest of the Mignon range; what changes is dose repeatability, not grind character.
Dialing in the Ode Gen 1
The original Ode had noticeably more fines than the Gen 2 that replaced it, which is why the Gen 2 burr upgrade became such a common retrofit. If you are running Gen 1 burrs, expect to sit slightly coarser than published Ode numbers to get the same cup.
