Values in dial marks from zero point. Center is the best starting point; low/high represent the typical range across different beans.
Sensitivity Zones
How much shot time changes per adjustment step in different zones of the dial.
Fine End
BMost sensitive zone — small changes have big impact on shot time
Mid Range

Coarse End
CLeast sensitive — larger adjustments needed to affect extraction
Tips & Quirks
Things to know about dialing in the Mignon Specialita.
Dial numbers repeat every rotation (0-5 marks, then back to 0). Users must count rotations from zero point to know their absolute position. Aftermarket dials (e.g., ARO dial) with more markings are popular upgrades.
Only adjust to a finer setting while the motor is running. Adjusting finer with the motor off can clamp down on a bean fragment and jam or stall the motor.
Factory calibration is inconsistent — the dial faceplate is installed at a random position. Every unit's '0' mark corresponds to a different grind size. Users must establish their own zero/chirp point.
Adjustment mechanism has backlash. Always approach your target setting by rotating clockwise (finer direction) to ensure repeatable positioning.
Grind retention of approximately 1g. Purge 1-2g of beans after changing grind setting before pulling your next shot.
Dial is very sensitive — changes for different beans are just a small fraction of one number mark. Make very small adjustments when dialing in.
Calibration
Unit-to-unit variance and zero-point info for the Mignon Specialita.
Variance
Zero Point
Burr chirp method: Remove hopper, run motor, rotate dial clockwise until burrs chirp (contact sound), then back off slightly. Zero point is NOT at the '0' mark — factory installs dial marker in arbitrary position. Each unit's zero is different.
Dial has backlash — always approach desired setting by rotating clockwise (toward finer). Catch cup/hopper can loosen and shift zero over time. Re-check zero periodically.
