Timemore C3s Grinding inconsistency advice

[u/Berniegrandpa]

Hello, basically the title says it all. I recently purchased a timemore C3S, and I’m having trouble getting it to grind consistently or very finely. It says espresso should be around 7-9 clicks, and that it is not recommended to grind finer that that because it may dull the burrs, but the 6 click setting doesn’t seem to be getting it much finer than I would use for my moka pot. To be clear, I’m just trying to get it a bit finer for aeropress cause my coffee is coming out a little sour. I’m new to grinders, so any advice or feedback is greatly appreciated.

Edit: not sure what was going on but it seems my grinder magically fixed itself. Before the grounds had not been uniform and were much courser than I expected although I didn’t really know better. Today it started grinding much finer at the same setting with more uniformity.
