6. INSTRUCTIONS FOR USE
6.1 INTRODUCTION
The LUCCA Atom 75 is a WiFi-enabled coffee grinder with a precise digital grind position sensor.
The mechanical portions of the Atom 75 are based on Eureka’s proven Atom platform,
manufactured by Conti Valerio, Srl. in Florence, Italy, which has been building excellent coffee
grinders since 1920. The electronic components and software were developed by LUCCA, a
coffee technology brand in Portland, Oregon, USA which has been bringing innovative coffee
products to market since 2011.
6.1.1 WHAT IS TrueGrind?
TrueGrind is an “Internet of Things” (IoT) system developed at LUCCA to help home and
professional baristas find the best grind setting for their espresso quickly and easily. Whether
you’re new to the game or a World Barista Champion, figuring out your grind setting (also known
as “dialing in”) is a challenging experience. Until now, the best any of us could do was pull a
bunch of shots and guess-and-check our way to the right setting with some handy but imprecise
heuristics (bucket of sand, anyone?).
Despite over a century of advances in espresso technology, this is still the same, sad state of the
art. We aim to change that.

6.1.2 THE TrueGrind SYSTEM
TrueGrind is a system of three parts which all work together to help you dial in your espresso.
The Grinder: LUCCA Atom 75
The LUCCA Atom 75 has been specially designed to work with TrueGrind. It is equipped with
custom, pre-seasoned and cryogenically hardened burrs for extreme grind stability, an ultra
precise digital burr position sensor which can detect grind changes as small as 5 microns, a
touchscreen display, and internet connectivity to allow you to load, edit and reference your
favorite coffees, recipes, and TrueGrind AI grind predictions.
The App: LUCCA TrueGrind for iOS & Android
The LUCCA TrueGrind mobile app lets you browse hundreds of coffee bags to purchase from
MistoBox, create recipes, get grind setting predictions, and sync them to the grinder.
The Brain: TrueGrind AI
TrueGrind AI is a Cloud-based artificial intelligence that thinks it’s a barista--if a barista could solve
partial differential equations in milliseconds. Tell TrueGrind AI about your espresso machine,
coffee beans, and the kind of shot you want, and it will predict the best grind setting to achieve it.
Not quite there on the first try? Use the Dial-In Assistant and TrueGrind AI will instantly learn and
correct its grind predictions based on your feedback.

6.2 USER CONTROLS
The LUCCA Atom 75 is controlled by interacting with the touchscreen, pushbutton switch and
grind adjustment knob.
6.2.1 TOUCHSCREEN
Using the touchscreen, you can navigate between different pages, view the current digital grind
setting, adjust grind time, connect the grinder to a local WiFi network, select the grinding mode,
stop and start grinding, receive and edit coffee recipes, view system information, and edit or
reset system settings.
6.2.2 PUSHBUTTON SWITCH
You can use the pushbutton switch below the grind dispensing chute to start or stop grinding
without having to use the touchscreen.
