Rocket R58 - Arrival Issues

Give those water spots one last try with barista wipes. These often work for me: {link} If that doesn't work and they are very noticeable, then maybe you can ask for replacement legs? That doesn't seem too much to ask to keep a customer happy. As to the loose gauge, I had other issues like this with machines I purchased...

Rocket R58 - Arrival Issues

Hello All, this is my first post. My family purchased me an R58 as a gift from Seattle Coffee Gear. Upon opening the box yesterday, we found what appears to be several water spots on the chrome legs. (Over a dozen) These do not wipe off with a microfiber cloth and Windex, which SCG recommended. Also... the right pressure gauge...

Ponte Vecchio Lusso steam pressure question

Yay! Success, problem solved. Yesterday when the machine was off for a long time the pressure was stuck at 0.5 bar even with the cap and valves open. So I checked the connection for the pressure gauge which seemed rather loose, I tightened it up and now, the needle is very responsive and the machine is working perfectly. I was...

Arco by goat story

Not worried about belts... Versalab/Honne already using one, just friction, no teeth, and it works just fine. Honne motor is AC too, but low RPM, 1350, and reduced to 360 via an 1:4 ratio pulley-belt assembly. Never heard so far about so big RPM A/C motor... eager to see it naked

I see you guys are building your own grinder from the ground up ! The ARCO is powered by an AC motor that spins at 15000 RPM. Direct mains, no speed control. This is then steped down to 360RPM thru a gearbox and a belt drive reduction. DC is a good option that has the benefit of allready having a...

What is your opinion on Wake Up Smart Home Coffee Roaster? (Kickstarter)

It's very reasonable to be concerned about inexperience leading to crappy tasting coffee. I can tell you that if you prefer darker roasts, the Gene Cafe is not difficult to use. I roasted with it for years using a simple process of preheat, add beans, listen for first crack, one temperature adjustment, and dump the beans when you hear the...

Just received an email re the Goat : "And now ARCO just got even better - with the 750K stretch goal reached we doubled the grind precision to super fine-tune your espresso, filter or any other cup of coffee"...what does this mean exactly?
