We make 4 shots each morning, and only use half the tank. Sometimes I forget to refill, but am still able to make at least 2 more the next morning. Note that it's fairly easy and quick to de-pressurize the tank through the steam wand, and then refill. It takes about 10 min to re-pressurize

This training video from Sunergos is the best I've seen: {video}

I'd second the Londinium. My Compressa has to be the most consistent and forgiving machine I've ever had - exactly zero sink shots. I'm still getting to know my new Vectis. Definitely a bit more finicky than Compressa, likely similar to other boiler-pressure / dipper machines. Seems to be very sensi...

I've found the Vectis to have perhaps too much steam power, especially when I use my smaller 25cl Motta pitcher. I've ordered a 2-hole tip to try to tame things a bit. My boiler seems to settle in at around 1.4bar, higher than the 1.2bar I've heard elsewhere. This will likely have an impact on steam...

I've had a Londinium Compressa for a couple of years and it's by far my favorite machine so far. I recently moved house and the new kitchen layout didn't easily support the Compressa, so I got a Vectis for its smaller footprint. I'm still in the learning phase on the Vectis (my first dipper machine)...

Day 2 on the Vectis. Still sorting out the recipe / process (different than my Compessa), but nonetheless some good output at this early stage... {image}

Not to get stuck in a rathole here, but in the past I found myself really chasing numbers with my espresso - measuring weight in/out to the hundredths of a gram, temp to the tenth of a degree, shot time to the tenth of a second, extraction % with a refractometer, etc. As an engineer it was all good

I really enjoyed using a Robot + hand grinder + bellman streamer on a weeklong sailing trip in the BVIs. We had 120V, but besides enjoying the quiet process in the morning and the excellent lever espresso, it was nice to be able to put everything away in a drawer when we started sailing. {image}

I can't say what you should do, but I sold my Max1 and MC1 and bought a new M4. Why? Vastly simpler workflow (no RDT or WDT needed) while consistently enabling great espresso with better mouthfeel than the Max1 and better flavor separation than the MC1. Downside? Initial retention and retention afte...

I've never experienced that on my Compressa. Have you posted on the Londinium forum or emailed Reiss? He's usually very quick to respond with useful ideas to further diagnose or fix issues, even if you are not the original purchaser
