    50 minutes is the accepted norm for Silvia to have all parts at correct operating temperature unless you use some tricks to speed the process up, such as activating the steam switch and running steam through the group, etc.
    Its all been documented before and a search should bring up the threads. Its possible to have Silvia at correct operating temperature in 15 minutes using the shortcuts. Easier though to just turn Silvia on 50 minutes before you want to pull a shot.

      Hey SPL.G

      Hows the silvia going now?

      In terms of the rocky number setting; all rockies are different, for example a number 7 on one machine could produce the same grind size as a number 11 on another. Its just a matter of mucking around until you find an OK grind setting for your dose (and tamp). There is also a stepless modification that some people do (if you find that the increments are too large).

      Just thought Id add that but if youve been reading around youve probably read that already.

      I found that changing to the Synesso double ridgeless basket was a good move.

      In terms of the water temperature
      The boiler goes on until the water in it has reached the top temperature (which doesnt take long as its a small volume of water in the boiler and a big coil), then it goes off again until the water has cooled to the bottom temperature and so on. So whilst the water in the boiler is heated the rest of the machine needs time to heat up. As the hot water runs from the boiler, through the plumbing and into the cup, heat is lost. So heat loss is minimised when the machine is hot and the cup is hot.

      Hope that makes sense

      Good luck with it!
      Cheers,
      -Sanch

        Hi Sanch,

        Still small problems with the Silvia, but they’re more like my stupid error instead of the machine.  Was going to test the temperature again this morning but didn’t have time , maybe tomorrow..

        About the Synesso basket, I have already ordered that from Greg along with the Pullman tamper.   Should be good!  … Still need to play around with the grinder setting though… but it’s hard to tell what a good grind is….

          Id recommend doing what Im doing SPL.G, just bite the bullet and experiment a lot, testing grind settings and being prepared to sink a few shots. Be a good little scientist though, and only change one variable at a time!

            If its grind tamp dose youre interested in - you could check out a couple of these ideas.

            Ive started using a naked PF - this helps massively with grind/tamp/dose because you can see any problems with the shot directly.
            http://www.home-barista.com/naked-extraction.html

            Also - following other reading Im going to try (when I can find some styrofoam cups) the Weiss grind/tamp method. Along with this Im going to measure the weight of the beans first on my gram scale.
            http://www.home-barista.com/weiss-di...technique.html

            Ive also Gronked my machine - which is attaching a $40 thermocouple to the outside of the boiler to get a "relative startpoint" for when I should run the shots - this makes temp surfing MUCH easier.
            http://coffeesnobs.com.au/YaBB.pl?num=1227428190/0

            All that seems like a lot of messing around - but if you have the same weight grinds in there every time - thats fixed. If you use Weiss method, the distribution should be pretty close to fixed. If you tamp the same pressure every time - thats fixed (kitchen scale as suggested), and if you run the shot at the same "relative" temprature then thats also fixed.

            As far as espresso goes - that will HELP to ensure you can reproduce the shot. And the naked PF will help you SEE youve done well.

            Thats my bag... but saying that... this morning I just loaded it all up - blasted it thru and wolfed it down. Still tasted pretty damn good. Go figure.

              Unfortunately it looks like the price of the Gronk standard thermometer has just gone up to $50 - at half the price of the much, much more useful CS Datalogger makes you ponder a bit harder about how long upgraditis can be held at bay.

                Im sure Ill go through the PIDing ritual soon enough, and Ive started doing Weiss, and waiting for a naked portafilter to arive. Buuuut...

                Where are you guys getting your scales? I could only find ones (at best) 1g accuracy.

                  Give Site Sponsors Coffee Parts a try first but if you cant find the sort of thing youre looking for there, this outfit are very good and can be personally recommended... http://tinyurl.com/q27lz6 and this one too... http://tinyurl.com/oer7bt
