  • 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?

              I had similar thoughts.

                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.

                              Cheers
