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?

Retention after one month of daily use.

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

simonc No, they are not very seasoned, but that shouldn’t affect feed rate, just flavor. Seasoning certainly won’t make the burrs sharper and cut faster. It has Stock burrs which are Mazzer copy. 18g in, 36g out in 33 seconds and takes 2 mins to grind everything at about 500rpm. Faster rpms causes the beans to jump and they don’t enter the burr teeth.

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?

simonc Clare has come back and said lack of consistency is due to lack of seasoning

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?

dfk41 I honestly would be raving about this as a filter grinder. The build quality is great, design is aesthetic. It came out as fantastic value. It’s also capable as an espresso grinder but I’m still having issues. If I get those worked through I’d say it’s pretty good for the price for espresso as I don’t know of any adjustable RPM flat burr espresso grinders for the price that compare but I know it’s getting close. The issue is that a .1 adjustment on the dial can mean a lot in terms of espresso seconds, but with careful movement you can still do fine. The battery part is fantastic to not have a cable and portability is great. Lots of upsides with a couple mild quirks that can be worked through I think. If I get the espresso feeding issue figured out I’d still say pretty positive things. I can’t think of anything else i would want without a major price hike. I have 2 kopis, niche zero, DF64 modded with SSP filter coffee burrs, timemore 078 turbo coming, and have run through others. For espresso, everything has some compromises/issues.

dcty No.. per instructions, 2 whole numbers off touch. I put a big container underneath and ran it through continuously in 200-300g batches. Creates a lot of static though so be warned there will be lots to clean up. Although prob quicker than WDT each batch of beans.
