Shims! Difficult to see but essentially to take up the space between the burr and its holder.

I've seen what you're referring to here on my Wilfa Svart.
Here's some things I've noticed as a result of a little experimentation:
- You can fit the top burrs in 2 orientations, in one orientation the burrs make a sound like they're touching at a much coarser setting (mid-aeropress) than in the other orientation.
- My top burr can rotate a few degrees within the plastic holder.
- Cleaning the grinder did make an improvement, but it's just made it more apparent how many fines the grinder is producing.
Quick Google suggests new burrs are £35 which doesn't seem crazy, but 2 years and 30-ish kg doesn't seem like it's really that long for the life of what's supposed to be a decent grinder. I'm going to try shimming my burrs first, then replacing them, but I think the fact the burrs can touch without even turning the dial to fully fine is a design flaw.
The sound I am now acutely aware of has been occurring for some time at finer grind settings that I don't normally use, which I thought wasn't great but I am now learning that even just touching once can kill the burrs and these cunts have been giving each other the kiss of death since only a couple of months after I bought it.

Interesting - will take a look at this
Timer on my Svart is a little flaky but I know my dose is ground when the burr sound moves from grinding to a high pitched scream! I’ve been meaning to investigate for a while and will look at shimming
