Grind Setting Tutorial for 1Zpresso Grinders

Grind Setting Tutorial for 1Zpresso (Easy-presso) Grinders

Greetings, fellow coffee-lover.
This tutorial allows you to learn how to read the 1Zpresso grind setting reference.

The 1Zpresso team calibrated all the burrs in the grinders to ensure maximum stability over time, as a result, the outer ring and the burr were built through precision finishing so tolerance was expected as the first few clicks of the outer ring and the burr would touch. Most importantly, the constant touching might damage the burr set.

In this tutorial, we wish the user understand the 1Zpresso grind setting for different adjustment designs. Firstly, we define the zero setting of the 1Zpresso grinders and teach you how to find the zero setting. Moreover, a little chart allows the user to understand the 1Zpresso adjustment design difference. Secondly, it is the grind setting tutorial for the internal adjustment design (Q2 & JX & JE grinder). Thirdly, it is the grind setting tutorial for the top adjustment design (JX-Pro & JE-Plus grinder). The last parts are the grind setting tutorials for the external adjustment design (J-Max & K-Pro & K-Plus & K-Max grinder).

How to find the Zero Setting

It is intuitive to adjust the external adjustment design. For instance, you could just note where the red dot points at the indicator.

It is quite easy for the internal and top adjustment design as well. Such as adjust the adjustment dial clockwise till you feel resistance, and that’s the zero setting.

These three kinds of adjustment design share a common point of the zero setting: at the click which the crank handle is unable to move drastically.

Adjustment design of 1Zpresso Manual Coffee Grinders

1Zpresso Grinders	Adjustment	Numbers per rotation	Clicks per rotation	Clicks per number	MM per click
Q2 & JX & JE	Internal	10 numbers	30 clicks	3 clicks	0.025mm
JX-Pro & JE-Plus	Top	10 numbers	40 clicks	4 clicks	0.0125mm
J-Max	External	9 numbers	90 clicks	10 clicks	0.0088mm
K-Plus & K-Pro & K-Max & ZP6 Special	External	9 numbers	90 clicks	10 clicks	0.022mm
K-Ultra	External	10 numbers	100 clicks	10 clicks	0.02mm

There are quite a few selections for the 1Zpresso grinders, the little chart helps the user spot the difference. For example, the user could tell the difference by the name of the grinders. Similarly, for other criteria as well (adjustment design, numbers per rotation, clicks per rotation, clicks per number, and microns per click).

We assume the user understands the 1Zpresso adjustment design difference. After that, the rest of the tutorials are the grind setting of different adjustment designs, in other words, how to adjust to the desired grind settings with the 1Zpresso grinders.
