I changed coffees all the time, but not a short intervals. Never less than a pound or so. When I did change coffees, I adjusted the dose / grind / boiler temperature / brew ratio until the shots were great. I also kept notes to easily get back to settings for similar coffees

I would make a copy of the profile before making any changes as the ability to "revert to original" still has not been implemented by JB

It varies dramatically by grinder -- I've opened up the all the single dose grinders I've tested, swept out the loose grinds from burrs, grind chamber and chute, and got from a superlative 0.05 grams to a failing 1.5 grams. But that is for another topic, not here

OT: When you select the profile, you can adjust the temperature by clicking on the +/- buttons: {image}

Yes it is

There are people here who are real experts on these machines, I just tend to remember trivial facts that I see here

There are many iterations of Larry Cotton's wobble disc roaster but it's how i started and it worked great. I have a Kaffelogic now and I feel the quality of the roast is better and consistent but the wobble disc roaster was a really good intro using a heat gun. {link}

thank you JRising for your response! My apologies for providing late update I got in touch with Stefano (from espressocare.com) the next day and he responded right away. Kudos to him for prompt response and providing answers to my concerns. here is his feedback if anybody is interested. 1) RE: pressurestat amperage replacing the low amperage

Tamping is tamping, not rocket science. And a manual transmission is more satisfying
