DrT, This is basically how I use mine (Variation do occur depending on the bean etc)..
OK, this is now I dose on my EM6900, bearing in mind I have the later release version of the product...(after 2 returned faulty units)
Using the Sunbeam EM0480 (What a awesome grinder!!!), Im using my own roasted Beans (50/50 blend of Indian Mysore Nuggets and Brazil) about 5 days old since roasted.
Set the grinder at 23-34 (Double basket)
Do an initial fill to a mountain in PF, lightly tamp to settle the first dose... then dose again creating a "mountain" effect in the PF. Tamp heavily (as prescribed), clean the PF edges.. You should have about 1-2 mil in clearance between the coffee grinds and the rim of the basket.
Insert into Group (Reasonable tightness) and do the extraction. I achieved an excellent dark brown pour throughout until blonding occurs and then I kill the extraction.
What I get is a sweet smelling aroma and medium-dark brown crema.
Puck is just that - A Puck with the shower screen inprint and screw! - Nothing soggy about it at all.
Hope this can guide your path on using the machine...
Note: My grind settings appears unusual considering others here are using the grinder at 12-16 setting... I did this but I found the grind was too fine... plus the Sunbeam baskets are larger than normal so a courser grind is nessesary... Let us know how you get on... it is practice and working out the dosing - Grind and Tamp... once you get it right, youll be fine.
