Where to start for espresso
No numbered scale. Find touch point (burrs chirping while running), then open 1.5-2.5 numbers for espresso. Same dial as Specialita (0-5 repeating). Fine-tune in 0.1-0.2 increments.
the stepless micrometric dial (small turn finer, large turn coarser)
Starting point only — adjust based on your beans, roast level, dose, and target yield.
