Is this what you're looking for? {link} I did a search in the github repository for "duty". There's also some configuration files for various roasting machines that override those values

I use a Pharos hand grinder, which cost me $300, is built like a tank, and gives me excellent results. As others have said, fresh coffee also makes a big difference. I roast my own, but it's also possible to buy very fresh beans. Pick beans with a roasted-on date, the more recent the better, some be...

Thanks for all the info. After giving all those pin lube threads another read, I bought some of this stuff, and will apply to the pins when it arrives: {link}

Thanks everyone! The video looks and sounds exactly like what I'm experiencing, except that I get the clicks/skips throughout the whole pull. Each click feels like the lever yields a small amount of give during the pull. I tried slathering a decent amount of Dow 111 all over the piston seals, along ...

+1 to home roasting. It's not that hard, and each 12oz batch takes me about 20 minutes total, once per week. It does take a little practice, but frankly, I think it's easier than cooking a great french-style omelette Roasting over the last 2 years has saved me hundreds of dollars. Also, the unexpect...

Thanks to everyone for the replies... On a warm machine with no basket but portafilter locked in, I don't detect skipping of any sort. I always flush some water out of the group before brewing, and the lever moves pretty smoothly. Skipping only happens when I'm pulling the lever downwards against th...

Interesting, thanks for the reply! I had to do a google image search to determine what the roller bushing is, but I think it's the little ring where the back/fulcrum lever pin sits. I think the opening in the group it sits in might be a little worn, but I don't remember how bad it is, didn't think to

I have a Gen 3 La Pavoni Europiccola with the plastic group sleeve. As I pull down the lever to extract a shot, I can feel/hear the piston skipping quite a bit inside of the grouphead. This has persisted despite having down the following over the past few months: In order: - (Inital refurbish februa...

I recently smashed the piggy bank and upgraded to a Pharos. I have never looked back... Before that, however, I used a cheap Kyocera MD50 (a.k.a. Hario Skerton, I believe): {link} I did the following super simple mods: - Added a cardboard cover to avoid flying bean fragments - Flipped the step adjus...

Hi folks, I'd like to understand something I observe happening when pulling shots on my Gen 3 La Pavoni with different coffees dialed in to different grinds. When I lift the lever a single time to pre-infuse, then pull the shot after about 8 seconds, I find that the amount of liquid I get in the sho...
