Arduino PID Tuning "Rocketscream controller"

Using Arduino Programming Questions
#1

Hello,

I am having trouble getting the PID controller (Arduino shield from rocketscream) to get to a setpoint. The temperature usually hover 5 degrees lower than the set temperature which is 150C.
Any suggestions on how to bump up the temperature to reach the setpoint ?

Thank you in advance
Please see attached image for the graph. My current parameters are Kp=150, Ki=0.001 and Kd=0.

No code, huh? Perhaps you need to adjust your Ki and Kd parameter values.

Increasing your 'I' term a little should bring you to your set point. But too much and it will oscillate around it.
