1Zpresso's own JX chart puts pour over (with siphon) at 2.2 to 3.0 rotations from zero, which is 22 to 30 numbers on the internal dial. Start at 2.5 rotations and move a few clicks at a time; each click is only about 25 microns.

Every numbered range above was checked against the source in the footnote it carries; where a manufacturer publishes nothing for a method, the row says so instead of inventing a number. Ranges are windows, not verdicts. Beans, roast age, and dose move the right setting inside each window, which is why the dial-in ladder below matters more than any single number.
How the 1Zpresso JX adjustment works
The 1Zpresso JX uses an internal dial under the burr: 10 numbers and 30 clicks per rotation, about 25 microns per click, read in rotations from zero. Find your zero before trusting any chart: with the hopper empty, tighten toward fine until the burrs just touch, call that zero, and count from there. If your zero point is calibrated differently from the chart's, every range shifts by the difference, which explains most "the chart is wrong" complaints.
Dial it in from the chart in 3 steps
1. Set the middle of the pour over range above and brew once, changing nothing else. 2. Taste against the two failure directions: sour, thin, or fast means grind finer; bitter, harsh, or stalled means grind coarser. The full logic lives in why espresso runs sour and why it runs bitter. 3. Move in small steps, one variable at a time, and write each attempt down; the free dial-in logbook exists for exactly this, and the printable dial-in cheat sheet keeps the correction table next to the machine.
