HarveyMushman Is there a reason manufacturers don’t use longer or more ergonomic levers for flow control? Not talking specifically about this one it’s just that the trend appears to have continued here.
I thought this lever was alright, it’s wood, so can’t get hot, it’s a reasonable size to give good control, yet handily sits above the front panel allowing a full 350 motion or more. That said, I have not used I yet and still need to calibrate it as the closed point is only 40% of the way from where you would expect it to be e.g. at 7 o’clock rather than 10 o’clock pm.
Bearing it mind it has programmable preinfusion (pressure) and time) or preinfusion with bloom phase (pressure and time)… I would probably only use the lever to close down and reduce pressure during the later portion of a shot as the puck erodes.
Temperature wise it’s looking very stable, but I need to conduct a lot more scace tests to come up with optimum settings for the boiler and group PIDs, plus the temperature differentials. I think that’s going to take the better part of a week (as you have to wait and let things stabilise, have 1 or 2 hours standing time, and produce clusters of shots. These scenarios all have to be explored at each different temperature in the 90-95C range.
