About the Comandante C40 MK4
The Comandante C40 MK4 is a manual hand grinder with 39 mm conical burrs and stepped adjustment. It reaches about 1400 µm at its coarsest, which covers all 20 brew methods we chart. Each click moves the grind by roughly 30 µm.
What we found on this machine
Checked against
Comandante's grind chart, page 12 of the C40 MK4 manual. Read September 03, 2026.
Comandante draws a chart rather than printing a table, so these bands were read off page 12 rather than copied from a list. The reading checks against a landmark the manual states in words: the factory-setting marker falls where its own caption says it does, at 24 clicks.
The bands are drawn with soft, faded ends rather than hard edges, so each figure here is good to about one click either way. They are recorded as they were read rather than rounded to look more precise than they are.
What the chart calls "Bialetti" is moka pot, and "cezve / ibrik" is Turkish. It draws a single band for filter brewing, so drip and V60 both read off that one. AeroPress is not on the chart at all, and no band has been invented for it.
Reading the chart changed this page. The settings here before it were espresso 5-14, moka 12-15, AeroPress 14-20, V60 18-28 and chemex 24-28, filed under Comandante's name. Two of those asserted bands Comandante never drew, moka is really 14-19 and chemex 28-34, and there was no Turkish row at all — even though the finest band on the chart is the cezve.

Comandante C40 MK4 — frequently asked questions
Is the Comandante C40 MK4 a manual or electric grinder?
The Comandante C40 MK4 is a manual hand grinder with 39 mm conical burrs.
How much does each click change the grind on the Comandante C40 MK4?
Each click on the Comandante C40 MK4 changes the grind by about 30 microns, so you can dial in small steps.
What grind sizes can the Comandante C40 MK4 produce?
At its coarsest the Comandante C40 MK4 reaches about 1400 µm, covering 20 of the brew methods we chart. Its finest setting isn't published, so we don't state one.
Can I copy grind settings from another grinder to the Comandante C40 MK4?
Not directly — every grinder's scale is arbitrary, so a number that works on one model won't match the Comandante C40 MK4. Match the micron range instead, using the chart above.
