Grinder settings, 18 grinders.
Every chart here is built the same way: two documented anchors — where espresso sits and where French press sits — with everything in between interpolated and quantised to what the dial can actually resolve. Starting points with an honest ± band, not targets.

One grinder in this list cannot reach an espresso grind at all. That is a property of the machine, not a gap in the data — the Fellow Ode is a brew-only grinder and its page says so plainly.

Why settings never transfer between grinders
A click is not a unit. On a 1Zpresso JX-Pro one click moves the burrs about 12.5 µm; on a J-Max S it moves them 8.8 µm; on a Comandante it is different again, and on a stepless DF64 there are no clicks at all — just a reference scale whose zero point drifts from unit to unit. That is why a "20 clicks" recipe is meaningless without naming the grinder, and why the same coffee lands at 18 on a C40, 46 on a JX-Pro and 3.5 on a Fellow Ode.
The grinder converter maps a setting from any grinder here onto any other through the shared universal scale these charts are built on.
Calibrate, then trust the chart
Published charts get the shape right — correct spacing between methods, correct direction of travel. What they cannot know is your unit's zero point, your burr wear, or whether the burrs are stock at all. Set your own espresso and French-press marks once and the whole chart re-derives around them, correcting both the offset and the slope in a single step.
Coffee Aeye carries all 18 charts, plus a custom-grinder path for anything not on this list. Rate a brew and it turns the fault you tasted into a concrete move — how many clicks, which direction, on your dial. Modified burrs? It knows the published chart no longer applies and falls back to a descriptor rather than quoting you a false number. Get it on Google Play — €4.29, one-time, no subscription.
Not on the list?
These 18 are the grinders with well-documented community charts to anchor against. Anything else belongs in the app's custom-grinder path, where you enter your own dial range and your own two anchors and get the same mapping built around your machine. Guessing at a chart for an undocumented grinder would be inventing data, so this list stays short on purpose.
