Grind settings chart. Dial: External dial numbered 0-10 per rotation, 10 clicks per number (100 clicks per rotation). 8.5 = number 8, click 5. Each click is a big step (about 20 microns), so espresso needs care. 1Zpresso's chart puts AeroPress, moka pot and drip in one shared band.

Where these numbers come from
Settings are starting points. Burrs wear, beans differ and two grinders of the same model can be calibrated a step or two apart. Taste, then adjust.
