1Zpresso no longer sells the J-Max new: its J series page marks it "Not Available" and links to the J-Ultra. Timemore sells the C3 in several versions (C3, C3S, Max, ESP, Pro). The settings on this page are for the standard C3 dial.

The same number means different things
Both grinders use a clicks, which makes it tempting to copy a number straight across. Setting 18 clicks sits at grind index 0 on the J-Max but 53.2 on the C3 — 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 J-Max
The J-Max trades coarse range for espresso resolution, and the click density near the fine end is the whole point of the grinder. If you are using it for pour over you are working in the middle of its range and will find it forgiving; if you are pulling shots, expect meaningful taste changes from two or three clicks. It will reach French press, but it is not what you bought it for.
Dialing in the C3
The best-value hand grinder in circulation and the one most likely to be someone's first. Its range is usable across filter and immersion, with espresso possible but genuinely tedious. The C3 benefits more than most grinders from a few seconds of settling before you judge a shot or a pour — its distribution tightens noticeably once the burrs are warm.
