The left paddle is designed in such a way that makes it a movement that requires a conscious decision to accomplish. It requires more force than a falling cup to pull the left paddle and the weight of the cup isnt enough to do that. Also u need a horizontal force not a downward force which is what a falling cup would exert typically anyway. It also cannot be a momentary force - you have to sustain a higher force than that across a certain horizontal range by continuously pulling the left paddle towards yourself.

I tried knocking the paddle in a downward facing force or a force directed diagonally downwards. The switch didn’t even move. Only a purely horizontal directed force will move the paddle.

Furthermore the pump fills the grouphead quickly, so that would mean almost immediately after the user releases the lever he has to engage the left paddle “accidentally” in order to cause insufficient water to be in the grouohead. But in doing so, the user will more likely also need to move out of line with the lever arm to the left of the group - which puts his chin out of the danger zone.

As for the microswitch alignment part, if it goes out if alignment the left paddle wont even open the valve at all. It is made so that it needs to pull a certain distance before activating the microswitch. That cannot somehow change by itself- unless it is deliberately sabotaged!

Therefore what you suggested is in fact as unlikely to happen as “accidentally” triggering the venting of the grouphead on the vostok by pressing the touch screen wrongly…I use the parentheses because both situations are also to me similarly unlikely to happen and would only be practically possible if one were to intentionally do so…

      Perhaps people behave in a more uninhibited fashion in an exhibition area than those who visit the residence of a friend or relative. Or others have.had less well behaved or more inebriated guests and visitors! :)

        I am aware u had a very early example of the nurri leva to test. On thd other hand i have been using the nurri every day since I got it in December and i have to point that the travel direction and the force required of the paddle make such an occurrence quite improbable - unless one actually engineers it to happen.

        A physically recessed button sounds easier to depress than a touchscreen option on a menu…

        While i suppose for the uniquely-“talented” toaster submerging brigade :), it may always be possible to have any type of accident but if that’s the case, then for them even a physically recessed button can be accidentally triggered at the wrong time … so it seems to me thar both situations belong to the same improbable category for everybody else…

          Yes which is finally why we asked what speed the lever would come back up at 🤣

          Got there in the end

            I don’t understand what u mean, Jake. Could u clarify what u mena by getting where in the end? The lever handle comes up at a smooth and safe speed when the venting function is actuated.

                I think Jake would like to see a video of the lever rising after the paddle has been used to depressurise the group at the start of a shot or with a blind basket.
                I promise to do one for the Vostok when I get it if one hasn’t already surfaced by then.

                Take it easy friend, you have a lovely highly capable machine.
                People are interested in it and will delve deeply into its capabilities and idiosyncrasies.
                Comments are just that not complaints nor insults.

                    I was not offended by what Cuprajake said. I literally did not understand what Cuprajake meant and thus was asking for him to clarify what he meant so that i can reply.

                        As far as I am concerned Antonio is a friend of mine, so if his machine brings him success, then good luck to him. We just need to celebrate the abundance of advanced levers, rather then the very over priced, underwhelming basic offerings we had before!

                            Indeed, enjoyment of coffee is what a spring lever is all about- elegance, ease, and above all, taste…

                              The Nurri comes with a mini drip tray riser that sits on the drip tray to elevate smaller cups closer to the group head.

                              The problem is that the riser is too narrow for my Acaia Lunar scale to sit on it and remain stable.

                              Ali Express to the rescue.

                                metal or plastic, it looks like the decent scale thing

                                  Amberale To be clear AA it’s not ideal. I’d far prefer to Nurri to make the riser tray wider.

                                  I am still a little surprised that a new machine doesn’t take into account that modern prosumers are going to want to use a scale. Even Decent, is only just starting to design a drip tray that accommodates a scale and there are a proliferation of aftermarket objects like the AE version above that are filling that gap.

                                  The Nurri riser is fine for a cup but it Antonio seems to have assumed that no one wants to use a scale.

                                  Same for shot mirrors although at least the Decent has one built in.

                                  So … the white stand, which is not exactly “integrated” into the look of the Nurri, may well prove to be a wobbly mis step in the right direction.
