Title: What should be my PID?
Post by: snakyjake on March 31, 2019, 01:25:43 AM

I have the 3D.

Which settings are the right ones to use: 

• Initial programmed controller settings?
• User Guide (page 16) settings?
• Smokin-It's OEM (https://www.smokinitforums.com/index.php?topic=4275.msg38567#msg38567)?

The initial PID that was programmed into my controller:
P = 60
I = 800
D = 150
T = 2s

The documentation/user guide/manual on page 16 has these initial values:
P = 7
I = 600
D = 150
T = 2

Parameters Used in Smokin-It's OEM (https://www.smokinitforums.com/index.php?topic=4275.msg38567#msg38567) controller

P   Proportional band   60         
I   Integral constant (second)   850         
d   Derivative constant (second)   130         
Model 3:

Thank you.

Looks like a set up for a moonshot.
Glad I have an analog...

The correct settings are the factory settings P 60, I 800, D 150.  You can always perform an auto tune if you feel it is necessary or tweak the values to get where you want the controller to go. I have not found a need to do either.
