Arco Macinino vs Arco Preciso
The Macinino is a solid stepped grinder that does the job reliably. The Preciso is a stepless grinder with near-zero retention that gives you control most people don't realise they're missing. The gap between these two grinders is often bigger than the gap between the machines they feed.

Beginners and anyone who wants a grinder that works predictably without overthinking the adjustment
Intermediate to advanced home baristas who dial in for each new bag and want zero retention for single-dosing
not suitable for
Anyone who changes beans frequently and needs to micro-adjust grind size — the stepped settings can leave you stuck between two settings
Anyone who doesn't want to think about grind adjustment — the Preciso's infinite range requires intention and a little patience
The Verdict
The Macinino is an honest grinder that punches above its price and pairs perfectly with the Primo for simple morning workflows. But if you are pulling shots on a Doppio or better and wonder why some days taste different from others, the grinder is almost always the answer. The Preciso's stepless adjustment and low retention make it the single most impactful upgrade many home baristas can make.
