dmau9600 This seems like a pretty good usable range, but I’m curious if I should be skewing toward higher flow when fully opened, or lower flow when closed?
I guess it depends on what shots you’re trying to do. For Normal espresso shots, your ratio will be about 1:3 maximum 1:3, for a Lungo (or Turbo shot as the next generation are calling it), you might push to 1:5
4g/s will allow for 120ml over 30s….more than enough for these shot styles. However, being able to close the valve completely, will allow you to bloom the puck for a period of time, then continue the shot. Me personally, I would set it to be able to close off the valve completely.
