Thank you for the question. I happen to have the same machine at home. I actually do not monkey with the grinder setting for a cafe crema. I do choose the 3 bean strength. The next thing to play with is the e-plus system. I perfer to set my e-plus to full open, so it is least restrictive and I pick up very few bitter notes doing it that way. I would start full open then close the e-plus valve to slow the flow to find the flavor you want.
