They started shipping them today. Anybody kickstarted it? ![A zero waste coffee grinder - engineered to the precision of a Formula race car. Literally.](https://ksr-ugc.imgix.net/assets/033/083/609/57fe7dfb9833c595341b7f015564c4aa_original.jpg?ixlib=rb-4.0.2&crop=faces&w=1552&h=873&fit=crop&v=1618172524&auto=format&frame=1&q=92&s=1075a8fbb5057244b2b2d499568e9260)

I am in lust. Would have been very very tempted had I seen that on Kickstarter at that price. Am sure it will be a lot more retail.

I considered getting this, but it being battery powered put me off to be honest. Does look beautiful though.

They're still available on indiegogo. Looks beautiful I agree. I'm waiting for early reviews as beta testers reported some issues like grind retention in the funnel, excess static, etc. Then if those are fixed to convince myself I need to upgrade on the eureka…

Battery powered?! How was that determined the most appropriate course of action? I appreciate 3kg per charge is probably about 3 months for most people but still… As above, it’ll be interesting to see how it deals with the usual grinder related complaints like static and retention.

Well i wouldn't worry about battery, have you seen an sds drill go through concrete 😂 Its a stunning little grinder, while not a fan of the sweepers, remind me of cable ties .. But it could be a little gem.

> @"Cuprajake"#p14108 But it could be a little gem. Isn't it a belt drive? I also remember the praise being heaped on the Lagom Mini, so it's best to actually see what it really does.

@"Cuprajake"#p14108 Your point about the drill got me thinking… Presumably if it’s not running on constant voltage, as the battery wears down the motor rpm will reduce, as with a cordless drill? EDIT: I just read the blurb and apparently it uses an ‘intelligent battery management system’ to regulate the power to the motor so it’s consistent as the battery drains. I wonder if the cordless approach was to avoid having to consider different voltages worldwide and ship the same product globally.

@"Ernie1"#p14125 It's an induction motor I think, so shouldn't slow down. my concern would be about the batteries…are they replaceable, did they use 18650 cells etc.. as they will have a limited lifespan. They have not stated the grind times by speed ranges either?

@"DavecUK"#p14127 Indeed, interesting they specifically talk about sustainability being ‘top of the list of design priorities’ but then use a disposable power source.

> @"Ernie1"#p14129 Indeed, interesting they specifically talk about sustainability being ‘top of the list of design priorities’ but then use a disposable power source. I guess they wanted it to be portable…the main thing to find out, is what they are not telling you! It certainly looks nice.

dfk41 Yes.. there is coffee in the chamber so clearly it ran and was tested, so likely a transit. Clare just emailed and explained how to check the button and can send a replacement if needed. Thankfully they are only just down the road so hopefully won’t take long to get here.

simonc

Waiting for confirmation on which terminal to put the blue wire back on to.

spivechild

Sounds like they’ll get it fixed relatively quick. Hopefully just a small hiccup in an otherwise great grinder based on my own experience.

Cuprajake

from the marks id say middle , but wait for confrimation

simonc

Cuprajake I was going to guess left, but you were right. I waited for confirmation… support is amazing, only 20 mins for a reply.

The white plastic behind the blue cable connector is supposed to be attached to the plastic zip tied near the left terminal which is a battery support, but in transit it obviously broke when mishandled. Makes you realise what happens with the couriers.

Now to get on with seasoning the burrs..

MattH

Looks nice and tidy in there 👍 - sure you will be up and running shortly !

simonc

Also discovered that cold starting doesnt work for espresso setting.. nothing came out and had to drop 2 notches. But with a hot start all good.

simonc

I’ve now put a kilo of beans though to season, Amazon £8/kg and can pour 16g beans in in one go and it grinds fine for espresso.

However the sheet with the grinder says touch point is 9. I think it’s starting to touch at 9.2.
I just ground at 9.5 and a 1:2.8 shot of light roast took just 33 seconds. I’m worried I’ve not got much room to go if I want to grind finer for longer shots or do long preinfusions.

Is this normal with flat burrs or a particular issue with the ND?

I could stall my minima quite happily with my Vario and can do on the Niche (I know it’s conical )

I don’t know what the ND is, but it doesn’t sound as if things are right, the grinder should be able to grind fine enough to get a longer shot than that, even with light beans, especially if you are so close to touching?

LMSC

simonc I just ground at 9.5 and a 1:2.8 shot of light roast took just 33 seconds.

Most of my light roast shots fall between 25s and 30s. This range is the sweet spot for me on my lever. I always go back to this time range after grinding finer aiming for 35s-40s shots. My typical ratio is 1:2.5.

simonc

DavecUK I meant KD Kopi Deva.

Yeah so far the experience with this has not been great. Customer service however is very good so confident I’ll get it sorted.

Cuprajake

Have you had it in bits to clean after seasoning?
Those cheap beans are terrible
Are you weighing in and out?

simonc

Cuprajake yes weigh in and out. In = Out to 0.1g.
Only thethe funnel off and very little In there

simonc

LMSC fair enough. I have preinfusion on the minima and also flow control so tend to do longer shots.
But regardless of where i end up dialling in for taste I should be able to get fine enough to stall. At the moment I think going to 9.3 might get me to 45 seconds but at risk of touching burrs.

Tjyven

Maybe ou should align the burrs even though that might not be the problem. Is really simple on the KD.

simonc

Tjyven maybe I might try but would like to have not needed to. Aligning Should be a finesse to a machine of this price, not required for espresso.

How far from touch are people grinding espresso?

Cuprajake

I meant to make sure the burrs were not caked in shit.

simonc

powderhorn Did you ever get this resolved? After 1.2kg I still can’t get it grind at espresso on a cold start, and then have to trickle the beans in a couple at a time to get it to grind 0.1-0.2 away from touch which gets me a 1:3 espresso with 16g in 35 seconds. No chance I could grind for a ristretto.

I am however getting minimal retention. After 3 shots it’s pretty perfectly clean inside. Wipers seem to be working

simonc

For the last 8 brews since yesterday I’m getting
20g out in 1min 20 @9.3
45g out in 1 min 10 @9.4
45g out in 35 seconds @9.5.
all for same 16g dose and 2 sprays at 1200rpm

Also 0.3G retention on some of these that came out on the next full dose, not even when I ground a few extra beans to make up to 16g.

Waiting to see what support say as impossible to dial in with that range.

LMSC

simonc 20g out in 1min 20 @9.3

Is it fair if I say that this is a chocking point for your machine?

Unfortunately, I do not have this grinder to share my experience. Based on your grind references, 45g out at 9.4 in 1:10 mins, and 20g at 1:20, you are already chocking the machine, assuming you aren’t touching the burrs at 9.3.

A few questions, if you don’t mind me asking.

Where was your average shot time before Kopi Deva, assuming this time-zone was your sweet spot.
How did you like the shots in the case of 45g shots in 30s to 45s? Which was your best cup?
How many bags of different coffee you have dialed in so far on this machine.

IMO, you may want to dial 10-12 bags at the best cup time zone (ie default grind size) and see how you get on. 😊

Cuprajake

What burrs are inside?
What basket are you using
Any papers or puck screens?
