Think of pid_kp as a dimmable light switch Now set pid_kd (derivative). pid_kd makes an impact when there is a change in temperature. It's used to reduce oscillations. -* If you have oscillations that take too long to settle, increase pid_kp -* If you have crazy, unpredictable behavior from the controller, reduce pid_kp +* If you have oscillations that take too long to settle, increase pid_kd +* If you have crazy, unpredictable behavior from the controller, reduce pid_kd Expect some overshoot as the kiln reaches the set temperature the first time, but no oscillation. Any holds or ramps after that should have a smooth transition and should remain really close to the set point [1 or 2 degrees F].
