Update, When I touched the metal tube that holds the probe, the display flashed off, and it reset. I just gave the machine a gentle bump by rocking it fore and aft, and it popped up to 24 or 25C. When I move my hand near the chamber - just holding my palm above the Boost ring, the temperature readin...

Yes, ticket logged.

I just turned the machine on. It shows the ambient temp to be around 9 to 10C.

The weird format showed briefly as “##..6”. I’m not sure if that’s 6C or negative 6C. Hopefully, it’s just a bad connection or a cold solder joint.

I just received my boost kit today, I activated it, attempted a roast, and my temp probe readings seem to be wrong. When the machine was just sitting there after the activation, the temperature showed something like **4. It seems to be a big negative offset, like it's below freeing. It's summer here...

Happy to help. For Dry Time, I watch for when there are no more green beans. It’s a bit subjective, but I find that it’s good to be patient. I often keep waiting, finally decide it’s time, record the temperature manually, and by the time I look back at the beans, they have started browning quickly. ...

The ROR wobbles don’t look too bad to me. The tracking of the profile is quite good, aside from the translation from preheat to PID control. I would bump up the fan speed, either with the calibration or in the profiles that you have chosen to help reduce tipping. Did you log dry and first crack time...

Success!!! I increased my fan calibration from 0.97 to 0.99 and tried the Ninja Turtle profile with a washed El Salvador, 1,000 to 1,300 m. The four 113g roasts were consistent with nice, stable tracking. Here are rough averages… Dry: 172C, 4:45, 57% FC: 199C, 6:35, 22% Drop: 216C, 8:20, 21% The fir...

@Geronimo - Thanks for the suggested profile. I also wait for a series of cracks before I log FC. I don’t trust the odd outlier. @rosemarycole - Yes, I get the runaway temps at the end, typically right after FC. FI get the rare “too slow” warning during the drying phase. I also don’t tend to use the...

My calibration is 0.97. A recent, difficult bean was Kenya Nyeri Gatugi AB. Washed. 1900m. I started with the 1200-1500 Rest profile. FC at 5:03. I then did 0-1200 Rest. I got it to 6:20 for FC, but preheat was low, and the log was very unstable. I stopped manually at 18% development, which was only...

Thanks! I’ll check the calibration shortly. Maybe I need more fan speed at my elevation (600m+). I’ve roasted a variety of beans, and I believe that most were washed. Rather than a bean issue, it seems difficult to get FC past about 5:30, and uneven roasts are chronic. I have a log and can list them...

It’s been challenging for me to do slow light roasts on the KL. Is it just me, but every bean seems to roast very quickly. Let’s start with the elevation Rest profiles. Even with high elevation beans, I find that I need to use low elevation profiles, and they can still be on the fast side (FC @ ~5:0...
