I changed from using one profile to using two: one for the pre-infusion and the second for the pour. I did this because I found that the pre-infusion time can vary with puck preparation and the time to ‘first drips’ can give me and indication of how everything is going when changing things. You can change profiles ‘on the fly’ but i stop and restart, to get separate times for the two stages.
When I decided to separate pre-infusion, I ‘cleverly’ set the first phase of my profile to 0sec at 2.0bar (intending to go back and amend the pre-infusion time later when I knew what was needed) but that did not work. When the first phase of a profile is set to 0sec, nothing happens - it does not jump to the next phase as it would anywhere else - so I set the first phase of my pour profiles to 2sec to overcome that. I’m so used to working that way now that I haven’t bothered to change.
One day I might start experimenting more with profiles, to see what I can get, but I’m too busy trying to ‘get a life’ right now!
It’s a shame that you cannot name each profile. I keep forgetting what the others were set up for and ‘post-it’ notes don’t look so clever, stuck to the front of the machine…
