I just watched JH's video for puck prep and noticed he's using a Specialita. Not the Specialita XL the 55mm burr Specialita which I thought was surprising. I have that same grinder and I shelved it a while ago but I decided if it's good enough for JH then maybe I should give it another try. Right away I had the same problem as I remember. I can't seem to grind fine enough. My burr touch is set almost right on 0 so I started at 2 and got a gusher, 1 is still too fast then went to just before burr touch, and finally a decent shot time. So I can get there but the problem is I really have no more play on this grind setting. I know it takes JH 17 seconds to grind thanks to his camera angle, mine is easily double that. Clearly, I'm going to the limits of this grinder but anything above 1 is a gusher, so I have less than 0-1 to play with then the burrs are touching. I've aligned this grinder too using the whiteboard marker method and where that was a while ago as I remember this was the exact reason why I shelved it sometime last year. The burrs are seasoned but they also don't have a lot of miles on them. I've consider getting new burrs for it but right now I don't have a lot of confidence in the grinder. Is this a common problem with others? My DF64 can go a lot finer and I don't have a problem with it's limits but I know burr design can play into as well. I'm using a DE1 on it which I think uses a IMS basket. I'm sure Hoffmann's Eagle One uses a precision basket too but who knows, could this be a basket problem? should I look at a traditional basket over a precision?

The Specialita' regulation system it's very sensible, small rotation of the knob can achieve great modification, moreover the diameter difference between the Specialita' knob and the DF64 wheel, giving the impression that with DF64 we grinds quite far from the burr touching point.
I personally use the Specialita' just 2 line marks coarser from the touching point, to be clear i have touching point at 2.5 mark and i grinds at 3.5.
I did watch the JH's video too, probably for the coffee he used he found out that the Specialita' was better, or maybe all others the grinders were broke

There has been a bad batch of burrs which lasted a whole year. Forgot exactly which period, but I guess all grinders produced between nov '19 - nov '20 (serial no. starting with PH00120****). From PH00121*** the issue was resolved and I guess old stock should be sold by now. It's (strangely enough) a pretty widespread issue where you can find very little about. Nearly everyone I spoke in forums (15+ people) had the affected burrs.

The solution is simple; contact your retailer and ask for new burrs. Note: Eureka does not deal with customers directly. You'll receive new burrs without a hassle and your grinder will be nearly two times faster and offer you twice the range for adjustment (if aligned correctly).

Again; not sure why you don't see this issue mentioned more frequently. I guess it's the curse of the internet where people tend to rave about their purchases and repeat positive (or negative) feedback to a point where it clouds judgement. This should've been a recall. I wouldn't discount the brand/grinder though, it's great value and same goes for the XL and Atoms but as with everything, minor issues occur and need to be adressed.

2 marks from burr touch is too coarse. I have to adjust as close as I can get to burr touch. The shot was drinkable but I would like to have more range with the grinder. With my DF64 if I got that close to burr touch it would choke the shot. My burr touch on the DF64 is right at the the first "o" in the warning "do not adjust past...". With the same coffee I grind at 2 in the DF64 and I have a generous amount of adjustment before burr touch. With the Specialita I'm at the threshold of burr touch. I can't accept the DF64 adjustment is that much finer than the specialita. It can take a full minute to grind when single dosing which is not the experience I see Hoffman having. I can feel the difference in tamping too and it doesn't compact as well (because it's too coarse) If this is a burr issue then I'll happily get new burrs.

I got a PH00121 so it's sounds like the issue. I'm happy that it's fixable but I'm not so sure I'll be able to get new burrs sent to me. I bought it at a reputable place but it's been a year... But I'll give it a try. Do you happen to know of an official statement from eureka that states this problem so I can send it with my request for new burrs? If I do buy new burrs at my own cost how do I know they are not defective too?

Addon: I've just realized that there may be a 50mm burr Specialita? I'm not really sure or what I have so I opened it up and measured it with some calipers. the largest I got was 53.91 outside diameter and 31.15 inside diameter. So that doesn't really clear things up, I know the measurement can be marketing so I assume it's the 55mm ones (because why would they market it as less). The issue is I can find 50mm burrs for sale but not 55mm burrs but I'm not really sure if they are actually different or if it's just marketing. I live in Indonesia so some of this information is not that clear, I'd have to have the seller measure them more precisely to know if they are the same size as my current ones.

Yes you are right, the Specialita 55 mm burrs actually have an outer diameter of 54 mm. The most accurate information about the actual size I found on https://www.espresso.co.nz/parts/coffee ... av1802-cp/
I also had the bad burrs, or actually one of them, and I got a new one from my retailer without any questions asked. The grinder is much faster and able to grind finer with the correct burrs. In my case the faulty burr had Eureka written on it with block letters instead of with curly ones.

There's no 50mm Specialita, then it's called different like a Manuale.

There are 2 types of burr screw configurations, one is like 3+ years old and the others are from 2019/2020/2021. Of those recent configuration the first year has this wrong burr set.

And most important; contact your reseller and simply ask them. You won't be the first and you won't be the last. The lengths people go-to to avoid this step often amaze me .

{Insert face palm} like this

Yes -that looks precisely the same as the bad one I had
Edit: added picture with the two versions: the upper one is the good one and the lower the bad. Also tried to circle the main difference between the two that I could identify

Yeah, get a new set and you should be good to go. I've seen a handful of users with the same issue here and on reddit. Tell-tale sign is slow grinding for espresso. IIRC, one came with a set of brew burrs. I don't think it affected all units for that 2019-2020 period because I got mine in June 2020 and have no issue (neither did many others I've seen during that period). GL!
