Hopefully, you can keep the profile smooth enough and appropriate for the bean to have it track the curve reasonably well. That said, one can taste a finishing temperature difference of 1C or of a 20 second difference with the same finishing temperature. See this article… https://millcityroasters.co...

You might also try the next higher elevation curve and stop the roast much sooner after FC. That last roast seems a bit long, but maybe that’s what is needed for that bean.

When I tried Raost v5 and Adaptive with Boost, I felt that they were much too fast. You can edit them by scaling the time of the roast and fan curves by about 110% and lowering the initial temperature of the profile. I did a test, using Ninja Turtle as the basis, with first crack at around 5, 6, 7, ...

I just roasted 150g of a Panama bean with zero in the collector. With an Ethiopian, I might get as many as 20. I think the solution is to use smaller batches for small, light beans. Also, I think mine fly up during the cooling stage, so they haven’t been any lighter than the main roast. Unless I’m f...

Great question, though I don’t have a great answer. When I first got my roaster, it had a subtle fault that messed with the temperature reading. Generally, roasts went too fast and were unpredictable. The problem is now sorted. Along the way, I sought out profiles that were more reliable. I didn’t r...

It's been at least a couple of weeks since the problem has been resolved, and the machine is working flawlessly. So, what was the issue? The capacitor on the temperature probe input to the circuit board had lifted, making the circuit prone to EMI, and messing up the temperature reading. As an electr...

Great news. Mike at Eight Ounce in Calgary received the roaster, replaced the thermocouple, determined that it was the problem, roasted two batches, sent me the logs, and will ship the repaired roaster to me tomorrow. Personally, it’s awesome. Okay, had he flown to my house and provided concierge se...

I would probably start with the Raost Adaptive profile. It starts the roast slowly. More recently, I’ve moved to the Ninja Turtle profile, which has an aggressive start and a slow development. I think some of my beans didn’t like the slower start of Roast Adaptive, so I switched. For a Kona bean, Ni...

Update: I got a prompt response from Kaffelogic after filing a problem report. After sharing information, logs, photos, and a video of the problem, they determined that it’s a hardware problem, possibly the thermocouple. Given that I’m in the US, they looped in Eight Ounce Coffee in Calgary, their N...

I dug out the old macro lens. The probe looks fine...
