Which to buy
Choose the
Barista Express Impress (built-in) if you…
- pull espresso — the conical burr grinder is built into the machine
- want the dose set for you — the machine calculates it from the last grind and remembers the correction
- want assisted tamping: a 22 lb (10 kg) press with a 7° twist
Choose the
Sculptor 078 if you…
- brew pour over — Timemore sells the 078 as "Pour-over Only"
- want 78 mm flat burrs and a 400 W motor with variable RPM
- pull espresso too — choose the 078S, whose burrs Timemore says suit espresso and pour over

The same number means different things
Both grinders use a numbered dial, which makes it tempting to copy a number straight across. Setting 10 sits at grind index 0 on the Barista Express Impress (built-in) but 62.5 on the Sculptor 078 — far enough apart to change the cup.
Converting a setting
If a recipe quotes a setting for one of these grinders, read across for the equivalent on the other. Rows are spaced evenly by grind size, not by dial number — on a conical burr those are not the same thing.

The shape of each dial
Where the connectors bunch, that grinder’s dial is compressed and single steps count for more. Comparing the two shapes tells you which gives finer control, and where.

Dialing in the Barista Express Impress (built-in)
The Impress version adds assisted dosing and tamping, but the grinder underneath dials much like the standard Barista Express. Its range is built around espresso; treat filter settings as the far edge of what it was designed to do.
Dialing in the Sculptor 078
The larger-burr Sculptor, and the one with a caveat worth knowing before you buy. The plain 078 ships Timemore's Turbo — “ghost” — burrs: pyramid-cut, aimed at a unimodal grind with few fines and little heat, and built for pour over. Owners consistently report it will not go fine enough for espresso, and its adjustment is stepped where the 078S is stepless. If espresso matters, the 078S is the model with the flat burrs and the fine control; this one is a filter grinder that happens to be excellent at it. Seventeen numbers cover espresso through filter here, so the brew range has real resolution. Retention is genuinely low once the rotary knocker has cleared the chute.
