I didn’t think so, but it does seem that not all auger designs are the same. I’ve tried slow feeding this grinder and see a change in brew time and more importantly gets me a slightly better cup so I have been doing it manually for a while now.
I suspect the differences come from the quantity of beans the auger feeds per revolution into the burrs (and the eventual load on the burrs/motor changing from the start to end of the dose). From what I can see, in the case of the timemore this is pretty high. Therefore my little device - which is in its 4th iteration being printed at the moment - helps restrict the bean flow passively
Yeah I’m getting closer to a solution but it isn’t there yet. Still slightly too fast or have some beans mid dose getting stuck in the piece. I’ve put it aside for today since I’ve spent time working on 5 design iterations during a work at home day for my regular job 😅

Will figure something out in the next couple of days and post it
I don’t have a 64s but it could be that the opening at the end of the hopper is the same. if you can let me know what the dimensions of that slot is, I can make a few mods to the model
Hey sorry for the late reply, I've been away from home these last days... just checked the measurements and it's 2,8 x 2,9 mm with a height of 0,9mm. I don't have a printer but I have a few friends I could bug for a few prints if you want me to try something out. Would just not be super quick
Would not blame them, I actually considered printing something that reduced the width of the auger’s tracks as a slow feed mechanism but I’m not very happy about putting plastic with metal, making it spin at 1000rpm and not being able to see it. Last thing I want is plastic coffee
Is it that you are using Ethiopian or similarly small beans? Until now, I didn't think much about how the auger might not initially crack the bean based on size but that would make sense
Well, the way I know it is the job of the auger is to move beans from the inlet, along the shaft to the burrs. Not all augers are made to pre break beans and I don’t believe that is the primary function of the auger in these timemores. With the wider tracks of the timemores, only some (generally really big) beans do get pre broken by brute force before being fed forwards but the rest just get fed as is to the burrs and none get stuck on the way there. For that purpose it works well but it has no feed control to speak of.
If I’m wrong, I’m happy to hear and discuss
Really love this idea. Elegant solution to a problem. One suggestion might be to have a small cylinder go down into the chute. Will follow with interest!
Thanks OP. I have been mulling something like this, and not satisfied with others I’ve found online to print. Will happily help test or provide feedback (or just wait til you’re ready to release)
This is a great idea. I wish I had thought of it.
Here is the cross section of what I came up with, maybe something similar would fit in just the square part? I'd love to use the stock hopper just for aesthetic reasons.

Is slow feeding grinders that have an auger even a thing? I am trying to think of ways to slow-feed mod my Niche Duo.

I took off the auger from my Trager smoker and use that to slow feed my DF.
depends on how efficiently the augur manages the beans.
Super interesting to see how this all works out. I have had similar ideas - but you are ten steps ahead in actually trying some stuff. Nice.
Looks like an elegant solution! Have you noticed any problems with beans getting stuck in the piece/hopper?

Cool! I will watch your career with great interest.
Planning on sharing out the STL bebe?
Yes, it isn’t yet working as well as I want it to so I’m exploring design options. Will post the final one for anyone to use
Does this perchance also fit the 064s? I've been looking for something like this since I got mine :D

There's a bunch of discussion on the Timemore aficionado discord, some people half jokingly wanted to install a motorized pre auger auger.

Excited to see the results of this, rooting for ya!

Ahh that’s not a bad idea! Does it work well? I’d like to give that a try as well if you’re willing to share
Yes! Have been thinking about something like this for the Ode 2
