    Eureka Atom Getting started?

    Hi Snobs

    I've taken the plunge, got a dream machine and upgraded also to the Atom. I am struggling with setup somewhat and wonder there is something wrong. Hoping someone can help?

    Once Ive got the grind close to where I want I adjusted the time went through an iterative process to get both where I'd like with about 20g of coffee in the portafilter. Once around 20g I would fine tune the grind slightly to get the best extraction.

    This is where I have problems. I would think the dose (in grams) would be the sameish when you change the grind and not the time but I find changing the grind size seems to significantly change the dose as well - finer seems to increase the dose and coarser opposite. This did not happen on my old grinder and the weight dispensed only changed when you changed the timer.

    Is there something wrong with me or the machine? In short - I would like the dose only to change when I change the timer and grind size changes not to effect dose weight. Any ideas, Thanks?

    I actually think that may be fairly standard for the dose to alter slightly with grind changes. The time that it grinds will stay the same, but the amount of coffee dispensed will be different possibly due to different sized particles and exit room.

    With my Compak K3 Touch Adv I think it's actually the opposite to you. Going finer tends to lower the dose dispensed, and coarser is more. My theory is that because the burrs are closer to together there's much less room for the coffee to move and exit, and when coarser the burrs are further apart and more coffee can shoot out. But I don't think that may be true haha, you'd think it would be the same regardless, as the burrs are still grinding them out just at different sizes...

    Interested in what others say

    Ps. And CONGRATS on the dream machine and Atom, awesome, hope you enjoy them

    I’m with Simon on here. From a timed dose if I make it finer then less grams out and vice versa.

    On my smart grinder I had and the macap m4d it was pretty much the same.

    You soon learn that this adjustment equals 0.x seconds adjustment to keep the grams same or near abouts.

    I had this on my Eureka Zenith when i first got it and agree with both above. I must say though i have mine in a pretty sweet spot at the moment.

    It sometimes just takes time and at the end of the day how does the coffee taste when you pull a shot?

    Thanks for responses - what you say makes sense.

    I'll have to play around with it. Wish there was a distributer you could call or something. Anyone know a number as my dose changed significantly with grind whereas my old grinder did not?

    Ive thrown away a lot of shots since getting it but when I've got it right its been great. Mind you that was the same with my old grinder which did a great job, just didn't have the fine tuning or consistency that I hope the atom will.

    Why don't you call the company you bought it from, after all they made the margin on your sale and should be providing the "full service" experience?

    First questions should always be to your retailer.

    Quite often they will know the answer even over and above our learned Coffee Snob community.

    It is likely that will have had the same query from other customers.

    Normally yes, but I got the impression they didn't know much about it. It was a display model bargain and they had no more.

    Ah yes! the bargain, guess you get what you pay for, there's a lot to be said for buying through a specialty retailer capable of offering expert after sales service.

    Check this thread out Grinch, http://coffeesnobs.com.au/grinders/45512-eureka-atom.html
    may well be a clue there.

    Just an update, but still a big problem.

    I got it the wrong way round, as people suggest finer grind reduces the dose but massively. eg about 1/8 of a turn results in 20g dose going down to 14g?? surely this is not right. Any ideas much appreciated.

    Thanks

    Grinch if you are still having problems why not try your retailer rather than assuming they know nothing? You might find someone who works there has the unit at home or similar. Also being able to take the grinder to their premises makes faultfinding so much easier, even for a grinder they don't regularly use. I would assume most retailers are looking to have a satisfied customer. The course I did for my admittedly bottom end gear made the world of difference to me.

    From what others have observed in the past, you only need a tiny adjustment on the Atom. Sounds like your 1/8 turn was too much of an adjustment. Your grinder seems to work fine to me, as long as you don't go too fine and clog it out that's ok.

    Here's what my workflow would look like using a timer grinder:

    Let's say it's currently grinding 20g in 20 sec, but the grind is too coarse.

    i) Adjust grind setting (finer by a tiny fraction)
    ii) Purge 3 s
    iii) Grind a dose into your portafilter. Say, you got 19g. Add a 0.5-2s to the timer depending on how much you're short of(but do not grind again).
    iv) Manually dose out another 1 g using the purge button.
    v) Pull a shot using your 20g (19g+1g) coffee.
    vi) If it's not fine enough, repeat from step (i).

    I have tried the retailer Essential Coffee Service in Marrickville - they know almost nothing much about this machine.

    They put me onto the distributer who told me to bring it in but it didn't sound right. Then I mentioned I live almost 1000km away in Sydney and he said he will get back see what they can suggest next week. Doesn't sound like an over the phone fix but also may be one of those problems that they say its working fine and not covered by warranty.

    Hi Grinch.
    Site sponser, Jetblack Espresso are at Frenchs Forrest. They stock this machine and might be able to help.

    It is a great grinder, I'm really happy with mine.

    +1 to this, great post.

    And absolutely I think 1/8 of a turn is far too big :S. You only need very slight adjustments, and I'm not too sure of the Atom's sensitivity to changes, but most grinders only need very small adjustments. I'm talking millimetres. When you think about it, having the burrs only a sliiiight bit closer together means that THOUSAND of coffee particles are all getting smaller together. This makes for quite a dramatic change overall in the end with the final dose! I can't think of a good example or analogy right now... oh how about only a slight bit change in the temperature all over the world (like by 1 degree) and the dramatic impact that would have.

    I'm sure there are faaar better examples but you get the jist XD

    Grinch, Samuels Laws instructions are perfect. I have read that Mr Law has one of the lowest retention grinders in the world, I believe the Atom has a higher retention, I would suggest 2 or 3 shots before changing grind and give the chute a bang so you know you are getting the new grind. Will take some coffee but worth it to be happy with the unit.

    Sorry you aren't getting satisfaction from your retailer

    The good thing with single dosing is you do away with all these headaches (zero purging, no adjusting dosing/timer etc). So the workflow suggested above has already accounted that Atom is a 'normal' grinder.

    The 3 sec purge came straight from an Atom user. But yeah, purging slightly more might be more thorough.

    Grinch, there're plenty of gems in the Atom thread if you haven't seen it already. Particularly there's also one piece of advice worth following from our sponsor Casa Espresso about running the grinder while adjusting.

    Hello Grinch,

    I am 99% certain that there is nothing wrong with your grinder.

    A shame you didn't go to a sponsor who would have advised you and then helped you set up your grinder to your machine. Many a time we have trouble shot problems via text or phone with customers, quite a few CS have been the benefit of this.

    I don't say this often but, the money you saved on a display model grinder is pretty much gone now with wasted coffee, time and lost coffee drinking. As a sponsor we are here to help CS and hopefully, sometimes it comes back the other way.

    Back to your immediate problem. I am not sure what grinder you have used before but if you are coming from a non digital grinder to the Atom then you need to understand that they work differently.
    Time will change dose, grind will change dose on the same time and so on.

    Its not hard but you need to vary the combination of dose, time and grind until you get.

    I would still encourage you to go back to where you purchased it from. Even though they may not have huge experience with the Atom, they are more then capable of running through the basics with you.

    One other feature of the Atom (and all the Eureka's) is the way the grind adjustment works. Once again depending on what grinder you have come from it may be something you are not used to. The Atom system is very very accurate; it only requires very small adjustments to get a noticeable change. An eighth of a turn is far too much when you are fine tunning, also something that should not be done when the grinder is not running.

    So remember; small adjustments and small time changes. Once you have it set you will never look back

    Cheers

    Thanks Antony, makes sense. I do believe the place I purchased it from has a good reputation and decent longevity, sadly just not much experience with this grinder.

    True about waste, I just through out 6 shots to get it right. This was part of the reason I upgraded to lower wastage and get better consistency but I found adjusting easier, but less precise on my old grinder - el cafe tranquillo. Once I get this one right the consistency is great.

    I'm usually going from my home roast (which seems to produce a shot far faster than ones I buy) to beans from beanhunter etc. My beans require a reasonable adjustment just to get the shot right, so I generally make it quite a bit finer and the the dose seems to drop from 20 to about 14 grams so then I have to play around with the timer usually adding a few seconds just to get back to the 20 grams. Then going back to purchased beans, try the process in reverse, really frustrating, I do feel like taking it back.

    I can't believe its just me and hope the grinder shouldn't work like this as I found it a lot easier with my previous el cheapo grinder.

    You've pretty much answered your own question. It would seem that the variation in the coffee going through the grinder, from home roast
    to purchased, is producing the changes in the grinder outcomes.

    Certainly it is not the grinder that is at fault. Any other 'high performance' grinder will give the same result.

    If you wish to vary the inputs that's your prerogative, by all means and why not?..... but give the grinder a break
    and learn how to adapt to changes in the bean input by being proactive at the grinder.

    Learn what the 'ball park' parameters are for the two coffee groups you have identified and adjust prior to grinding.
    Learn to work with your new equipment rather than fight against preconceived notions of how you think it should work.

    Analyse what it is about your home roast that is different ... is it roast level or rest time? Getting good equipment often means a tightening
    of technique as it is less forgiving and that is a price we welcome as the outcome is (or should be) more knowledge and better coffee.
    Pods and fully automatics are for the one button wonders who cherish thoughtless process over quality coffee and
    as you have chosen a 'higher' path you might have to climb the hill.

    Really great post. This line in particular stuck with me: "Learn to work with your new equipment rather than fight against preconceived notions of how you think it should work."

    Food for thought and I'd agree 100% CD if I didn't have a totally different experience with my old grinder.

    This one is indeed a fight that I'd like to work with rather than against. The distributer from Melbourne seems to think this is not normal so therefore there is the possibility that something is wrong - I hope so as it is difficult to work with.

    It might not be a bad idea to take it and a bag of beans back to the distributor in Melbourne personally and running through the said issues with them...

    Hi Thegrinch..

    I am totally new to the home brewing and coffee scene so have very limited experience to draw on. I also have the atom and it took me a while to get it to the stage where the grind suited my tastes and the coffee 'poured' as i believe it should.

    If it is of any help I can have a difference of a gram or so in the basket for the same timed dose. I make no changes to the settings and the difference in weight can be from one grind to the next.

    I always aim for around 20 grams in the basket as, for me, this give me the taste and feel I am after and the beauty of this grinder is that I have one button set to 10.5 seconds and one to 1 second (+/- a few seconds depending on first weigh).

    My method it is do the first grind and 10.5 seconds, weigh and then grind at 1 second (give or take) to get my ball park weigh (not an exact science). I have got to the stage now where I know how long my second grind needs to be to get me to my target weight zone.

    I think you might send yourself mad if you try to be too perfectionist about it as there are so many variables that can affect the end weight and that are largely beyond control.

    Still the best grinder for me and the I love the end result

    Have never used an Atom so cant comment, however am following the thread with interest, guess it's easy to sit on the side and assume user error when it may well not be.

    Eureka Atom Getting started?

    As already observed I think your major issue is changing from home roasted beans to your Bean Hunter subscription beans.

    Even by your own observations your home bean settings are very different from the commercially roasted beans.

    I can appreciate your frustrations but you are probably not doing yourself any favours by jumping from bean to bean while trying to come to terms with a new grinder.

    My advice ? Stick with one bean, including one brand if the bean is from your Bean Hunter subscription for at least two weeks while you try learn about your new grinder.

    I sincerely doubt there is anything wrong with your grinder , however changing the parameters as you are may make it appear so.

    Cheers

    I’m not sure there’s much wrong with the grinder as Anthony has said. I think you probably chose the wrong grinder for “your” needs and would be better with a sette 270w (or any other with same features) that grinds to weight no matter what grind size you choose.

    Happy to trade you one for your atom

    Yep, highly recommend sticking with one bean and not switching so often, having to redial it in etc.. grab a kilo or two of something, and make small adjustments when needed. Noting how that changed the pour, and always only changing one variable at a time

    Was tempted by the 270w but went with this as I believe the build quality is better, its quieter and the tech which is great in the 270w is pushing the limits and I think more likely to fail. Would still consider a swap with $600 cash on a similar age one under warranty.

Then going back to purchased beans, try the process in reverse, really frustrating, I do feel like taking it back.

    I can't believe its just me and hope the grinder shouldn't work like this as I found it a lot easier with my previous el cheapo grinder.
    A bit late to the party but I just saw this thread and as an incredibly fussy espresso drinker with an Atom for almost a year now thought I may be able to help you - assuming you still have the Atom

    First, are you filling the hopper at least half full?
    Initially I was hopeful of single dosing the Atom - this was a very frustrating experience with inconsistent grinds and many wasted kilos of good beans
    Having it at least half full will produce amazingly consistent grinds and therefore shots. I use an Acaia Lunar for measuring grinds as well as every shot and once dialed in, can reproduce D:20g, Y:43g, T:28 seconds all day long (using a Expobar Minore IV).

    Second, adjustments are incredibly sensitive on the Atom. You should DEFINATELY stick to one bean until you feel you've mastered it. The smallest possible adjustment (approx 0.5-1mm of a turn) can result in ~1-2 seconds extraction time (for the same yield).
    My recipe book has grind levels measured in 1.4, 1.5 etc on the grinder - it's hard to judge precisely so i have a small piece of plastic with a marker on it touching against the dial which helps a lot if you want to return to the same grind setting.

    Third, when you're talking about different grind time, absolutely it changes with grind adjustment and also bean to bean. If you're going between two beans regularly why not set the single dose preset to one bean and the double to the other? Once you have the adjustments right time should be consistent, but if you want precision you will always have to weigh the output. I generally run 20g doses and have the time preset on the Atom set to give me 20.3 - 20.5 and then use a teaspoon to get back to 20.0.
    I can't prove it but I have a strong suspicion that running under 20 and then "topping up" with short bursts produces inconsistent results, compared with one single grind going over the desired weight and then removing the excess.

    Lastly, retention may be a lot less than many other grinders, but it's still significant. You need to run 3 seconds of grinds through after making an adjustment to see the difference, so change, 3 second dump, then grind your next dose. At the end of the day you NEED to bag the beans, spoon as much out of the top as possible, grind until empty, vacuum, then dump again and a little bit more will come out. These "leftovers" will not just push out first on the next day, they will mix with your fresh beans and make them taste stale for I don't know how many shots, big waste of time.
    With a clean machine at the start of a new day or when changing to new beans (after dump+vacuum) you need to run through 12-15 seconds of new beans before it starts going consistent. If you try to pull your dump shot with those first 12-15 seconds of grinds it will be way off your expected yield\time so is useless as a dial in shot.

    Following the above procedure I can 90% guarantee that after the dump\dial in shot each day, the next shot will be perfect D\Y\T and very consistent in flavour.
    Keep in mind, this is coming from a very fussy espresso drinker

    Hope that helps.

    Some great points there

    Ah that's fascinating... I'm wondering if anyone else has found this? Have seen many experts recommend the dose, collapse, dose rest method, but definitely food for thought and something I may play around with..

    I would have thought the 'top up' dose would have the same consistency as the initial grind as you are really just pushing out beans that have been ground during the first 20 seconds.. for all intensive purposes you are purging and unless the 'top up' goes for more than 3 seconds are unlikely to be getting newly ground beans (these wont be expelled until the next purge)

    This is exactly what I find. As long as the top up is short it's identical.

    Ah that's interesting... I usually dose about 2/3 of the shot, collapse, then dose the last 1/3. Have had consistency issues before but after changing burrs it seems to have settled, but I'll keep this mind anyway. Maybe will just dose the whole lot and collapse halfway while it's still dosing...

    I wonder why stopping the grinder then restarting would have an effect, like what reason would it create inconsistent grinds if the burrs are still the same distance apart?

    Perhaps upon starting grinding there is some other vibrational movement before it stabilizes, thus creating a slight change of grind size? Just hypothesizing hehe

    The only difference I've noticed starting and stopping is that you don't get quite as much out with a stop in the middle compared to one unbroken grind. E.g. 15s = 20g, but 7.5s + 7.5s = 19.2g (rough estimate from memory).
