I have some images from when I was struggling with the PID setting values before, so I will upload them.

When the PID setting could not be determined, I could not cope with the feedback delay and hunting occurred.

It's not perfect yet, but I found a setting to make and still trace the ROR curve of the tinker with the profile design of ARTISAN.

At first I was using a button to switch the PID setting to get the data, but I didn't want to waste coffee beans, so I was looking for a dummy PID setting to get the data at a lower temperature.

However, I took a detour until I realized that it was important to match the goahed seconds of the Artisan control to the response of the roasting machine itself, not just the PID setting.
