    They are the baskets which came with the machine (not after market), but I will try measuring by mass (weight). The 30ml and 60ml shots I refer to DOES include the crema too now that I think of it.

    Yes rather than measuring in mils, what is the weight of the liquid (more accurate than volume)?

    Are they just the single and double baskets that came with the machine, are they after market baskets, what is the recommended dose for each basket?

      I may also try removing the anti-clump screen too I guess; I mean it is clogging anyway, so maybe it'll work.

        I tried removing the anti static thingy once. My guess is that no one else will try it more than once.

I had a roast where i got distracted and overcooked the roast, the beans were oily before i got to use them. Used them anyway and towards the end of that batch started having jamming problems, eventually jamming totally on the bean after. Cleaned everything after with a clean dry cloth, especially the chute and covering rubber. Also because this was a bad jam actually removed the declumper and did the same to it (usually just use a pin between the prongs). No more problems after and back to my old schedule of every few months when i am in the mood.


          One other variable is try a different basket, probably not even aftermarket as they usually require finer grinds, to see if that changes the grind enough to solve the problem
          Yeah it is a darker roast- and interesting your mention of oiliness too as these beans do seem on the oily side. It has been suggested to me that- if I wish to retain the settings I have mentioned- I go to a lighter roast style.

            I always took oily beans to mean over roasted, wiser heads than me will confirm if that is right or not. The roast I am using at the moment is dark without being oily

              Is it difficult to remove?

                No. I am guessing the resulting grounds leave the chute with too much velocity but will let the Ninja explain what he means.

                  OK, Level3ninja- here is the new and revised breakdown-
                  single shot; 16gms of ground coffee, pulled 30ml in 28 seconds and the shot weighed 25gms.
                  double shot; 21 gms ground coffee, pulled 60mls in 21 seconds and the shot weighed 46gms.

                    Yeah, I really like the espresso that I make with these beans, BUT, I will try a lighter roast next bean purchase. At the end of the day, if I cannot get this grinder to deliver the grind that I want, I will just sell it (especially while it's still under warranty) and I'll buy a grinder that can do a finer grind without clogging up I guess. In the meantime though, if a lighter roast style saves me doing that and still gives me a good espresso, I at least need to try that I guess.

                        The actual fluid volume of those shots (assuming 20% extraction) will be ~ 23.5 ml and ~ 44 ml respectively.

                        Begs the question, when talking shot volume is it the fluid volume or the volume including crema that is usually quoted?

                          It is typically quoted including crema, hence it is a very noisy measure of output.

                            Very easy to remove. Thankfully just as easy to replace. The resulting static and velocity mean a 5cm radius around around the exit chute and below ends up covered in grinds.

                              I don't know your machine or the baskets that come with it well enough to say either way, but that sounds like you're at the high end of doses. Some baskets can handle it, some won't. What you're describing makes me think one of two things is happening; either you're changing the grind setting too much between shots or you're way too fine. When I first got my Atom I did both at different points.

                              Due to the internal retention I find it takes around 3-4 shots for a change in grind setting to come through 100%. It's 80% through after the first shot but if you keep adjusting shot after shot you'll chase your own tail.

                              I've only used half a dozen different beans with the Atom, so I can't say it's not your beans specifically, but there was a time when I choked the chute up and had to pull it apart. I eventually figured out that I was grinding so fine the water was going around the puck. When I backed the grind off intially the pour got slower but then it got faster again once I was back in the right ballpark and I could then fine tune from there.

                                Probably contacting the vendor you bought the system from and ask if some basic barista lessons can be arranged. Won't cost you much and may even be complimentary...

                                Failing that, you could do a similar thing by contacting one of our Site Sponsors, who deals in both major items of your system, and request the same assistance. https://www.casaespresso.com.au/
