I apologize if this question is redundant but I haven't found an answer on the forums yet.
We've had our Preciso for about 3 or 4 months. We don't use it heavily, but we grind around 45 grams of coffee on setting 34 each day. I noticed this week that it is producing a lot more fines than usual. This is evident in how much fine sediment is left in the cup. Up until this week I have been impressed on how little fines/sediment is produced by this grinder. I'm not sure if it is related, but early this week I heard a bit of a clunk when it was grinding. Since then it seems like the fines have increased.

Hopefully that "clunk"was not a stone, but it could have been the top burr lifting out of place. How often do you clean your grinder? Remove the top burr, clean everything well (both top and bottom burr, vacuum out burr housing), etc and check to make sure all three plastic tabs are on the top burr carrier are present or not cracked. Also check to see if the large black adjustment ring that surrounds the bottom burr doesn't have excessive movement (press down on it at different clock positions). Besides more fines, how does your grounds look? When I had this problem, besides excessive fines, I was getting sizes all over the spectrum. My problem was that the adjustment ring was not glued down. You may have one that slipped through without being glued down. Give Baratza a call too, their customer service is second to NONE! Take care!
The pathologically precise are annoying, but right!
