LMSC Clogs and they do not seem to have fixed the issues from DF64. The chute is not ideal. The de-clumper is useless
Regarding clogging and the chute — having used my DF83 twice a day every day since the beginning of December, I’ve never experienced clogging. The only reports of clogging I’ve seen have been in the context of grinding a lot of beans at once for seasoning the burrs. Lance mentions this in his video, and that’s what was mentioned in the other report of clogging that I’ve seen.
I’m also pretty sure that the taper was added to the chute to prevent spray of the ground coffee as it exits the chute. I can say that one thing that held me back on getting a DF64 was the spray issue, and I was pleasantly surprised at the lack of spray I’m getting with the DF83. In fact, the stream of ground coffee seems pretty focused, and I think the taper in the chute is partly responsible for that.
I can’t really speak to what the declumper is or isn’t doing, other than to say that I don’t have any issues with my DF83 that I could trace to the declumper being poorly designed.
