    Tate, very impressive what you've done. I just wish the manufacturers of machines would start to incorporate some of your tech into their machines. By yourself, you are outperforming the major brands in innovation. I wish they'd hire you or let you jump start their lame product development teams. Or alternatively, it would be great if you'd make your board available commercially to DIY coffee nerds that want to follow your lead.

    Cool stuff! using the pump to build pressure for preinfusion makes sense. Superauto machines do this (Gaggia and Saeco-Phillips at least). I use the following preinfusion method for my Giotto which is plumbed at 3 bar: 1)open valve 2) wait for drips 3)pull shot. Time from start of preinfuse to first drips is about 6 seconds when things are optimal. (grind, headroom).

  • @zenmark42
    @zenmark42 Рік тому +1

    somehow I missed this video so now I've got that bell on... this is such wonderful content I really love this kind of stuff. I have a little delonghi dedica deluxe and it seems to do what you're talking about with a preinfusion and then running the pump and I guess its counting pumps kinda like you were or something because I recently changed beans and it's taking waaay longer despite being set by time according to the manual (it must actually set by number of pumps?)
    anyways love your channel. also if you want to mess with fully automatic machines I'd love to know your deep dive opinions since apparently I'm looking for one for work...

  • @stevephla

    LM should incorporate some of your ideas (i.e. bloom, flow rate monitoring) into their app. I recently added the retrofit wifi connect kit to my old GS3 and it adds some of these capabilities (prebrew time, preinfusion time, scheduling, etc). But you've really taken full advantage of the possibilities in ways the have not. Very nice.

    Ok that's way better than what I was working on. I just have a GS3 turning on remotely and was working on doing remote flow control via a dimmer on the pump. You should see if you can add dose by weight using an Acaia lunar or something similar... That's always been something interesting that not many machines have.

  • @froggymaier
    @froggymaier Рік тому +1

    Nice video. Just as a note, your no pump valve open pre-infusion (bloom) does not act as slayer pre-infusion, since there is no flow as soon as the pressure equilibrated. There will be an inrush of water into the puck until pressure in the boiler and at the puck are equal. The reason you see a slow trickle of flow without any puck is a slow but steady drainage of water from the boiler itself through the flow-restrictor. It is the official reason LM does not implement this, because there is theoretical risk of burning you heating element if you left it drain too long. Cheers!

    • @tatemazer
      @tatemazer  Рік тому +1

      Yeah it's slayer-ish only because it's long 😅, but more similar to just a regular line pressure preinfusion. That's really interesting information about La Marzocco's reasoning. I'm fascinating by the idea that you could drain the group that way. I've got an experiment to try... 🤓

    • @froggymaier
      @froggymaier Рік тому +1

      Long for sure 😃
      And I guess draining is more of an issue for the Linea Mini, draining in the GS3s boiler will only occur as long as the water inlet (for the brew head inside the boiler) sits below water level..

    hi, this is really incredible. I have a La Marzocco GS3 MP but it is from 2016 so no ability to pressure profile. on reservior so no line pressure. i have noticed if i activate the paddle part of the way the valve opens to boiler pressure but haven't played around with that (but i will now that i have seen this). would this mod work for the MP as well? Is this something that can be taught or am I just overly optimistic? again, super cool stuff, great video, good luck to you! maybe you would enjoy a visit to Charleston, SC to modify my machine ;)

    • @tatemazer
      @tatemazer  Рік тому +1

      Thanks! The flowmeter is downstream of the pump and reasonably accurate since it doesn't use an opv to maintain the pressure. I usually see it accurate to about a half a gram. The pressure gauge for the brew pressure is just at the boiler, not the puck. However the GS3 MP version does have a pressure gauge at the puck

    Very cool! I'd like one of your boards.
    Question: Why don't you just go with a BLDC gear pump with full flow/pressure control? Then you could have a decent-style graph where you change the flowrate or the pressure over time by adjusting some sliders?
    I have a mod in the works replacing a vibe pump for a BLDC gear pump. It will be totally analog, so the end result will be a little box with a potentiometer 0-5V controlling the pump and a tachometer display that will show the ml/s which I can derive from the rpm.
    I'd LOVE to have a profile programmed that I could run every time the pump comes on, but that's beyond me. Maybe you can do it and sell me a board? lol.
    EDIT: I see you did that already on your previous machine minus the board control of the pump. Any plans to work on that?

    • @tatemazer
