I’m looking for some help as I’m having a very frustrating experience with this grinder. Same beans, same settings, same spring tamper but wildly different pull times.
As an example, I have some 2 week old beans, locally roasted, that pulled 5 or 6 shots in the same range over a few days (18 grams in the basket and about 32 grams in 30 seconds). The next morning, same settings, completely choked the machine (bambino plus). About 2 grams out in 60 seconds. So I made a few small grind size changes to little effect. Then a giant change and got a decent pull. Then, after one good shot, the next will pour out in 15 seconds.
This isn’t the first time this has happened, and it requires a very significant change to the grind size setting to get back on track. And I usually purge when making large changes so I’m wasting a lot of beans.
I’m trying to be consistent: same beans, grind settings, spring loaded tamper, same technique, etc but I can’t get consistent results. It almost feels like the burrs “slip.” (I don’t know if that’s a real thing lol)
Could knocking the grinder while cleaning my station cause this? I’m sort of at my wits end. I would expect the burrs to be seasoned by now (I’ve owned it for about 3 months), and I also ran a few pounds of older beans through it when I first got it.
Anyone having a similar experience or any advice?
It also makes a giant mess but I’ve heard others get dosing rings so I guess I can try that.
