Nurri Leva S.A.

i dont think it matters - it all ends up in the drip tray regardless

id like to see what the display screen does as thats different too.

chlorox Yep - in fact, if you buy a 3 group machine (heck, last I counted, Nurri, Evo and Vostok 1 makes 3), there is enough money for 3 really good grinders. On the other hand - at least in terms of size - it’s clearly meant for a commercial application. Whether it has the robustness/reliability that I would want for commercial use… different question altogether, but LM should know a thing or two about engineering coffee machines. If I won the lottery, would I buy it? Probably not. Plenty of other stuff would come first.

Correct, in its current shape and form. But what @chlorox was saying is that if the machine measured the exact amount of water required for an espresso… technically it would not waste water. However, there will be other issues, like filling the piston with air instead, so that would have to be overcome too, etc, etc, etc.

@chlorox - I’m enjoying the read and discussions :-) 👍

@dfk41 - The whole point here is that in the Nurri the paddle is there for those who think it’s useful and want to use it. You don’t have to.

the one top left, that has the timer on, i presumed you could press stuff on that

and thats where you adjust settings?

Cuprajake

Temperature settings for all three things, yes.

Viernes can you upload vids without all the music id love to hear the actual workings of the machine, cheers

Yeah ive seen those, but there all non users - real world stuff.

its ok though thanks

Viernes BTW, you can purchase the L-Type without pump. :)

Really? My dealer was going to talk to Antonio about such a machine but I didn’t hold much hope. Did you see any details of it online or hear of it straight from Antonio?

Or are you going to tell me it’s just a normal Nurri without the pump installed, with disconnected pipes,😃

That is impressive cup clearance.

simonko From Antonio. It’s the same machine but without the pump, so you must plumb the machine.

I think he still sells it. But better ask him.

Cuprajake and thats where you adjust settings?

It is, you can’t adjust the PIDs settings though.

DavecUK - are the PID parameters fixed?

tompoland PID stands for proportional integral derivative. It’s the control algorithm that is used to keep the temp where you want it. Being able to change the values for the P, I and D terms changes how it behaves, which can be good or bad depending on how well it was setup initially

tompoland PID stands for Proportional Integral Derivative

It’s a way of designing a (temperature - but it could be any other variable) process controller so that the output of the controller is a function of the instant error [i.e. proportional to Current Value - Target], of the error’s derivative [i.e. is the error expected to increase or decrease in the future based on its ‘instant trend’] and the error’s integral [i.e. has the error been increasing or decreasing over a certain time period in the past]. If properly calibrated, it’s significantly better at keeping a process ‘on track’ than a simple ‘on-off’ switch based on whether the Current Value is above or below the Target.

Note that there are at least 4 parameters that define a PID’s setup: the target for the variable under control, and constants for the Proportional, Integral and Derivative ‘parts’ of the error measurement. When @DavecUK says “you can’t adjust the PID settings” he is referring to the parameters other than the target (temperature in the most common case for a coffee machine). These can be important as they may need to be significantly different to provide stable and accurate control from system to system.

If you want the theory, history and maths, this Wikipedia article has probably more than you want to know; if you have any specific questions, do ask!
