Really nice! I’m excited for you both for the robot and the mods and plans for your Gaggia!
I have a MaraX that I’ve adjusted for 9 bar, though I seldom reach that these days since I’m mostly doing turbo shots 2.8 to 3 ratios with fruity light roasts.
I really want a lever machine (maybe a pre-mill Pavoni) but I’m short on space at the moment!
