    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).
    +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

        Thanks Mal, and everyone else. Great group. Pity I'm so damn obsessed with good coffee! Actually no it isn't.

          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...

                        Cheers.

                          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.

                              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 [emoji6]
