I used 600N with 2.25 setting (I understand every 600N is different in terms of setting). Non-pressurized filter. Very slight coffee granule residue. Not as much as yours.

After a few more trials, I found using a coraser grinder setting, together with a slightly higher dose at 13g and higher tamping pressure at around 30 pounds, should help the coffee residue issue. The flow of the expresso (now syrup looking flow), the amount of crema and the taste have also improved too. The high speed leaking from the basket holes is also much reduced.
