I’m sure if you had the goal of getting it to tip and did an unnatural pull you could get it to tip but that applies to any lever. In normal use neither myself or any of the other 3 baristas have had the slightest movement. The table it is on is smooth and a bit slippy so I use 2 rubber tamper bases ( that came with a Force Tamper ) to stop it sliding on the table. Can’t get it to slide at all now. Even with the weight removed it is still a wee bit heavier than the Vesuvius. I removed it lifting it any distance with the weight was not enjoyable. And yes I weighed it at 8kg

Viernes AFAIK there are only 2 machines in the world with these features. The other one is the Kees Van der Westen Slim Jim Idrocompresso, which shares the pressure gauge, timer, flush paddle and release paddle.

That’s very interesting and very I impressive too! I’ve learnt more about the Nurri from your posts than the Nurri website. Really appreciated tx @Viernes

    Sorry, too late, but thank you for the wishes, Coyote :)

    CoyoteOldMan Well… while the ACS machine has an 8 kg counterweight, the overall weight of both is similar, so there must be some additional weighting going on in the Nurri - the other components are pretty similar in size and weight, after all. Again, one plus point (group height clearance) which is missing from all published information; it “seems so” from the photos, but only a user (you) can confirm it.

    There’s no ballast or counterweight in the Nurri. It weights what it weights because of the materials used. Also keep in mind that it has a big rotary pump

    CoyoteOldMan In fact, from the photos, it seems to have 2 - but again, there is no information on what they measure. The one on the left is clearly group pressure. I assume the one on the right is for steam/service boiler pressure, considering the scale and the fact that it doesn’t seem to move when pulling a shot.

    Left gauge - Group pressure

    Right gauge - Steam pressure

    CoyoteOldMan Where did you get this information and the rest, including the use of CAD to design the structure? Just to be clear, I’m not doubting your word; I’m just trying to find out as much info as I can, be it on English, Spanish, Italian, French, Dutch or German forums… or any other language! Google search is not my friend, in this case. Again - thanks for posting, this is very useful for me in the current “undecided” situation, but it’s also going to be useful to others researching the machine.

    Information comes from Antonio Nurri itself. I did a lot of research and I asked Antonio a million questions before purchasing the machine.

    Yes, google search is not your friend, nor mine in this case :) There’s no user information (until now), that’s why I went straight to the source.

    I have another video. I suppose some of you have already seen it. But here it is.

              Viernes I have another video.

              Thank you. This is another use for the large rotary pump, I guess?

              I hope you don’t mind another (I won’t say “a last”) question: how is the pre-infusion/pump pressure regulated? Do you need to open the machine and adjust a pressostat, or is it done through electronics?

                  CoyoteOldMan

                  Yes, it could be. But it’s only for fun and to see “what happens if….” :)

                  I set the pump pressure to 8 bar to see if it was possible to pull a shot like a regular pump machine… and it works. But you can imagine, that now then the preinfusion will be done at 8 bar :)

                  You regulate the pressure by adjusting the pump. Luckily there is a hole and there is no need to remove any panel.

                  btw, my machine comes with a rubber ring around the hole for a better finish.

                      Viernes I spent the first 17 seconds of the video wondering what the mysterious red material inside an espresso machine might have been… then I understood what I was seeing 🤣

                      Muchísimas gracias, señor

                          Potentially damaging confession:

                          I can’t help but contrast @Viernes “peppered Antonio with one million questions” to my “I see, I like, I buy” approach. 🤩

                          To be fair, I simply wanted to know that it was a La San Marco spring system and that it had stable temperature. Other than that it looks gorgeous.

                          Nevertheless I’m feeling assured that the machine passed the Viernes inquisition.

                          What exactly is the difference between the grouphead used by the Evo Leva and the one used by Nurri? I hear the Evo Leva has some reports about leaking, water coming up and out of the top of the group.. problems with seals, trying to find one that works? Some people never completely solving these issues to absolute certainty? Is the difference in design of the Nurri such that this cannot/should not be an issue? Or is there any objective advantage to one or the other (aside from aesthetics)?

                            Hugonl37 Some users (including on this forum) report issues with the seal on the ACS. Known differences in the two groupheads are:

                            1. Presence of a pressure release valve in the Nurri (actuated by the left paddle)
                            2. Nurri group thermally isolated from machine body
                            3. Group pressure gauge mounted on the machine body vs. on the group

                            There is very little information on the Nurri group, other than it is a La San Marco-style with added heating cartridges (like the one on the ACS). It is possible that it is fundamentally similar to the ACS in other innovations/modifications (single rather than triple seal, extensive use of stainless steel, complex spring profile), but there is no information available. Reliability for any of this is obviously another unknown, considering the Nurri machine has only recently been released, and very few people have one.

                              11 days later

                              I believe that the Nurri machine has a fully brass group (with no stainless steel liner like the ACS Evo).

                              Tjyven here’s a thread on the Streitman but not so much a comparison with the Decent (mis-rememebered I suspect) https://coffeetime.freeflarum.com/d/476-nurri-leva-sa?page=3

                              The Decent / Valexia post may be found here https://coffeesnobs.com.au/forum/equipment/brewing-equipment-extreme-machines-3000/886809-decent-de1xl-and-izzo-valexia-leva

                              Please feel free to ask any questions.

                              The “best” machine is of course relative to personal preference. My preferences have me leaning towards lever machines because of the more sensual (as in “senses”) experience of the espresso pour. However if I want to easily and accurately play with variables and see what happens, then the Decent is reigns supreme.

                                  tompoland Thank you very much! So far I most been using a pump machine but I have decided I will buy a lever machine very soon, just so difficult to choose one.

                                      Tjyven Ah, we have all been there! Make a list of the features you want. For example if you think that it is important to be able to steam milk, but not all the time, then look for a dual boiler. If you think it is important to have PID control of the dual boilers then look for that. If you want a machine that heats up in 15 minutes using heat cartridges, look for that. The ACS Vesuvius Evo Leva ticks all those boxes
