The same number means different things

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 JX-Pro
External adjustment makes this the easiest hand grinder to actually dial, because you can count clicks without disassembling anything. Its filter range is generous, which is a mixed blessing — small click changes do less than you expect at the coarse end and more than you expect near espresso. Move in larger jumps for French press, single clicks for anything under filter.
Dialing in the X-Ultra
The X series is 1Zpresso's more affordable line, and the X-Ultra is the filter-oriented member of it. Comfortable across pour over and immersion; the espresso end exists but lacks the click density of the J and K series.
