Now that I am also progressing down the roasters rabbit hole... I searched for any previous requests for an automatic weight loss % calculation request and found this post. The formula I use is (Wt_pre - Wt_post)/Wt_pre*100, which is a pain with a basic calculator because the numerator has 2 terms. ...

I'm roasting an espresso blend. It hits FC and consistently goes exothermic within 30s. The roast ends early (lower than target development) because of the temperature overshoot. I added a -6 boost starting at FC, which helped a bit. I suspect I need more like -15 and will try that in future roasts....

Given the nonlinearity of the overall roasting process (and the use of a PID to work through this), I'm intrigued that the elevation based profiles include relatively sharp changes in T vs t (in contrast to the default profile). What is the motivation of adding such quick changes in RoR / temperatur...

To start, I'm quite new to roasting so forgive my potentially fundmental questions... Logs (I hope I attached the images correctly) show overshoot (diverge and proceed with an offset) after CC. All roasts L 3.0. 'default' and '15002000' (for file/image) refer to the profiles. If the image attachment...

Another member of the Fb group correctly noted that, just like the fan speed, the voltage can be recalibrated. Given that I have a volt meter (which I trust), I have recalibrated my KL Nano.

Please (KL team?) let me know if recalibrating the input voltage based upon a measured value is ill advised.

I ordered and received my KL-nano in Canada this week (yay!) and upon turning it on, I receive these notices on the display: * Supply 110V may be too low..., and * 1160W available, 1200W preferred. I have tested the line with a meter, and it shows 120V. I've confirmed the same messages and meter vol...
