What kind of coffee do you want to make?
Like most coffee grinders, the very good Smart Grinder is not calibrated. This means that what is good for my espresso may not be right for your grinder.
For an excellent Italian "espresso" I use Kimbo Napoli beans 🫘. I like 15g finely ground in the sieve so that the water runs through in 30-40 seconds. That means with my grinder:
Grind size: 13.6
Grind time: 14.6

Does that help?
