Noul Dalla Corte STUDIO 2019 grup saturat DC - successor DC MINI 2006-2018

Dalla Corte a evitat mereu sa dea posibilitatea utilizatorilor sa se joace cu diversii parametrii ai PID ului. Mai sunt pe ceva masini mai vechi un coeficient delta, insa e mai mult un interval de cateva grade care poate fi definit ca o toleranta pentru boilerul de abur, sa nu porneasca prea des rezistenta. Acum este inlocuit de modul "Eco" care are un algoritm predefinit.

Cel putin la boilerul de cafea chiar nu cred ca e recomandat sa existe posibilitatea modificarii parametrilor, chiar si un simplu offset incurca de multe ori. De exemplu cam toate DB E61 au un offset din fabrica calibrat corect sau nu insa am intalnit suficiente persoane care au modificat intentionat sau din greseala si au intrat intr o dilema totala legat de temperatura reala a apei ce loveste pucul de cafea..

La DC nu exista offset si din masuratori diferenta de temperatura de unde masoara proba de temperatura in boiler si ce curge pe grup este de pana intr-un grad, deci nu vad ce optiuni in meniu pe PID ar putea optimiza asta. 

Daca baga ceva de preinfuzie, asteptam cu drag Smile

Din ce am gasit eu in ceva newsletter:

"The Studio firmware has been updated. The 104e firmware incorporates
several improvements and some bug fixes. The Italian and English display
text was also updated. Spanish and German were added (the next update
will include French and Portuguese for the Brazilian market)."

Tare as vrea sa vad cum s-ar putea modifica codul pentru preinfuzie Big Grin

Al meu acasa inca are pompa veche, n am apucat sa o schimb insa nu am constatat inconstanta la extractie din cauza asta.

Wow, I haven't received any notification about new posts, so have not looked here.
My manometer is also shaking hand, but I'm not sure if all the time or ocassionally only. Will watch more carefully. Thanks for the info.

This way please, simple programmable automatic flow profiling upgrade (1st version).
https://youtu.be/I294DREzmR8
There are 3 flows available:
- preinfusion (adjustable by needle valve);
- lowered flow (adjustable by needle valve);
- maximal flow (factory default)
Digitally controlled/programmable time periods for each step, enough number of steps, any combilation of pre-set flows, e.g:
1/ max flow only (like factory default);
2/ preinfusion + max. flow;
3/ preinfusion + lowered flow;
4/ preinfusion + max. flow + lowered flow;
...

Altele nu au avut pana acum probleme si asa cum se mentiona si mai sus, Dalla Corte are teoretic un singur model de boiler care este si grup, un singur tip de garnituri, un singur furnizor, acelasi, de 15 ani de zile. Statistic nu prea am mai auzit de chestia asta, probabil sunt ceva cazuri izolate. 
I think the problem might be in quite rough grouphead bayonet groove machinig. I smoothened and polished the PF lugs where they were worn with dentist tools, but still new wear occured after single use, so I did it again. Now I can tighten the PF close to 90 deg. and make it tight, but quite a big force is required. I made a picture of the inside of the bayonet groove using 2 mirrors (very difficult to do, so the result is not as good as I would like) and found rough mill traces, which cause too much friction when PF is tightened, so I think that's the problem of workmanship. Maybe it is within DC machining tolerances and lucky people got better machining than me or Elian. It's a difficult to prove the problem to DC staff, our dealer has not offered me any solution except of gasket replacement, DC technicians want to see the video with leakage and PF tightened to 90deg, which is not possible unless I use hammer, and PF will not leak for sure then.

How was thine done?
What is the engineering behind this?
I am really curious...

Definitely not plug and play solution - 2 extra needle valves to preset the flows, 2 extra solenoids to control the flow, electronics to control solenoids, 1x extra non-contact water level sensor for low water pre-warning (before the 2nd sensor turns off boiler heating and pump), new hydraulic routings, everything put in very tight space inside the machine. Upgrade is fully reversible, no single modification to the machine (!), so even more challenging. It requires good electronics knowledge, high level manual skills, and to have access to some technologies, like laser cutting, milling, ...

Multumesc frumos!

Nu este prima ei lucrare pe echipamente de cafea.

În schimb i-am lăsat "mana liberă". Am avut încredere ca va face ceva frumos. Cred, totuși, ca a complotat un pic cu soția mea.

Peter - your group is still leacking?

You have a nicely tuned up Studio. You really have a powerful machine.

Thanks. If I tightened it very very hard, it usually doesn't leak, but if tightened PF just hard, it leaks. See the latest video of long preinfusion, classic extraction, time 0:27, few drops of water fell to the cup (not visible, but the rest of the drops remained on the bottom of the handle),


What did help in your case?

I honestly do not know what the service guy from DC has truly done to my machine. I still did not have the common sense to ask him. In that day I was really in a hurry (wife and kids waiting in the car).
All that I can say is that he removed the shower and dispersion plate, removed the seal (but did not change it) and after that he put them back in place. I do not have any leaks and the PF locks easier.

Hmmm, I've changed gasket 3 times, re-mounted difusor and shower screen un-countable times and still PF goes hard. There are even new wear traces on PF lugs after last polishing. I'm waiting for the oportunity to send the machine to the dealer for inspection by car (not by courier to prevent packing and possible damage during transportation), but have no high hopes at all Sad

Multumesc.
Cat despre Niche, am mai scris una alta pe threadul de Niche sau pote la Kinu făcând o comparație.
Am sa revin cu informații și despre S + u ⋑ ı o, doar sa ne împrietenim.

Salutare!

Si eu sunt curios Smile. E un pic nevoie de timp pana sa imi dau seama de una-alta si sa pot compara.
Dar voi reveni cu impresii de indata ce le am.
