simonc I can only speak from memory now, I have it as a secondary grinder and at the moment is is packed down because I will be moving soon. The smallest adjustment I usually made were about half a step, that would be 0.05, and I think that changed the shot time with about 3 seconds. I usually have about 20g of beans. Dont remember how far from touch I am but think more than 0.5.

Tjyven thanks. That sounds a sensible step in brew times.

powderhorn I’ve got the same problem on mine. I emailed KD and am waiting. This is my kickstarter unit and when I grind fine enough to hit 2:1 18g in and 36g out the beans won’t feed. When I coarsen the grind the beans feed better but the shot is too fast. Stock kickstarter burrs. I’m considering switching to SSP HU to see if that fixes it. DId you find an answer?

Mod: Two short wipers. One pointing down.

One pointing up.

Clare has come back and said lack of consistency is due to lack of seasoning, and 1.5kg is not enough, and needs 3kg (instructutions say 2kg) I dont actually have a consistency issue, and the shot times are consistent, the issue is lack of control over the burr spacing. I wouldn’t have thought that seasoning would have a big issue, but will try another kg through them and see.
Apparently reducing rpm to 700-900 rather than maximum will also help.. Will see.

dcty What weight of beans have you put through them so far? I presume these are sufficiently seasoned?

are they not ssp burrs?

Cuprajake I thought they were Mazzer as standard, but you can fit SSP into them?

just the colour thats throwing me

dcty My burrs wouldn’t grab the beans for espresso initially unless I fed 3 beans at a time. If I dumped the whole dose in nothing would feed and I would have to open it wide to a filter setting to get anything to start grinding. Now I can do 18g in one go at 1200. I am about 1.5kg so far. 1kg of that was cheap Amazon beans.

simonc Interesting…so seasoning sped up the feeding of the beans? Doesn’t seem intuitive but can try for sure. Need to find some cheap beans and try. I do see where density of the current beans and maybe light/dark makes a difference.

dcty I never followed the development of this grinder. Can I ask if this was a known issue and if so, how did the ‘influencers’ cover it?

I’ve had two big conical burr grinders that had consistency issues until seasoned with 2kg. I have no way of knowing if that was related to the burrs or the design of the burr carriers / grinder.

I’m dubious about her claim but based on those two outliers (mentioned above) I guess it’s possible.

shouldnt really affect feed rate though should it?

tompoland this is flat burr.

dcty weirdly it did. Amazon do a kg of beans for £8. It makes a mess though feeding them through bulk.

simonc Definitely worth trying then! I’ll leave feedback when I’m done. Did you season at an expresso level grind I assume?
