Kopi Deva

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.

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

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

from the marks id say middle , but wait for confrimation

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

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..

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.

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?

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.

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.

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

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

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.

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

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

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.

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