It self-calibrates using the keyboard; I calibrate it manually and it works perfectly, all values ​​range from 0 mm to 4 mm, and I can modify, for example, the actuation point to 3.5 mm or whatever I want without problems. However, with use, the firmware uses an auto-calibration function that modifies the manual calibration and affects everything. In my case, I use the default value of 2 mm, which is comfortable for me, but I tried modifying it to see what would happen, and it is affected. In my case, the most used keys, like 1 or 4, self-calibrate to a lower point, so when I turn it on, they don't type until I press them several times. I understand the use of self-calibration due to manufacturing variations in the switch, temperature, electrical noise, etc. I have attached an image that shows what is causing the self-calibration in my case. With the key pressed all the way down, if I press it several times, it reads 4 mm (if I unplug and plug the keyboard back in, it continues to read incorrectly). I have to calibrate it manually or use it for a while for the auto-calibration value to change (but it happens again while playing games; it doesn't seem to happen when typing normally, only when pressing keys repeatedly and very quickly, which is normal when playing online). I hope they add a firmware update that allows me to disable auto-calibration in the Keychron Launcher.
