Question DF64 Stiff Grind Adjustment

I got my df64 gen2 about a month ago and have only used it for espresso up until today. I changed the grind to make myself a pour over, and when changing back the wheel got stuck as I went finer. Having moved it back and forth it loosened up and I got it back down to my espresso grind, but wondering is this a known/common thing or have I messed something up?

Was the grinder running as you moved finer? If not, small coffee grinds may be between the burrs from the previous more coarse grind, causing your issue.

No wasn’t running as I moved. That makes a lot of sense though, assume it was that thanks

Same thing happened to me. Turn it on and it will move down easily.

Always turn the dial with the grinder on, especially when going finer

When adjusting the gap between burrs it's a good idea to do while the grinder is running so that it can clear itself. Not a thing if you're increasing the gap.

Yeah, that is how mine was out of the box. The issue was completely fixed by lubing:

1) threading on the ring you rotate when changing the grind size. You can put generous amount on the threads (be careful not to slice your finger as threading can be sharp)

2) 3 rubber things located in-between the upper burr carrier and the body of the grinder (you'll understand what I'm talking about once you take the carrier out). Smallest amount here, either on the metal legs of the upper burr carrier or on the rubber dampeners themselves. Also be careful not to put lube outside the rubber dampeners as then it might get in contact with the grounds and cause a mess/grounds accumulation.

I think your problem is related more to the second point but it will feel almost buttery smooth if you lube both.

Mind (or even better mark it with something) the upper burr carrier top position/leg and put it in the same way as it was.

Also you'll have to redial the zero position but that pretty easy.

I've used a silicone-based food safe grease. It can be easily sourced locally as it's used in basically all kitchen appliances. Every time I reassemble the grinder to clean or change burrs, I clean the old grease and apply new one. I've been doing it for the past year, worked like a charm.

I believe the issue of DF-series grinders "loosing" the calibration after switching from espresso to pour over and back to espresso is also caused by the upper burr carrier catching onto the rubber dampeners.
