> If you want to pid tune, you should generally think about which sort of filament do you take the most of your prints. I´m using the most of the time PLA at about 210°C with no printpartcooler.

> If you use the most of the time a printpartcooler i suggest you to run the fan at 100% for pid tuning.
> 
> For running the Partcoolerfan with 100% enter: M106  
> If you want to turn it off again enter: M107

> Enter following to the terminal for pid tuning: M303 C10 E0 S210  
> [M303=PID Tuning] [C10=amount of testing(10times)] [E0=Extruder] [S210=Temperature]  
> If you have done so, you have to wait a few minutes, till following response comes (Your values will be different!):

> Recv: Classic PID  
> Recv: Kp: 9.06  
> Recv: Ki: 1.57  
> Recv: Kd: 13.05  
> Recv: PID Autotune finished! Put the last Kp, Ki and Kd constants from below into Configuration.h

> Now you see my new P9.06 I1.57 D13.05 values.
> 
> To write it to the machine we enter: M301 P9.06 I1.57 D13.05 E0  
> Now you have to save your configuration entering: M500
