Does PID Tuning work on SM2?

Haven´t tried pid-tuning yet.- There was no need.

M303 PID AUTOTUNING

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

this is currently not available, you would have to edit the firmware configuration.
