How does the M221 PID auto-tuning work?

The M221 PID auto-tuning method is different from Twido.

To do an autotuning between set point +-3 or 4 degrees, how should we configure the M221 PID parameters?
The "measurement range" fields must be used.
The current behaviour is that amplitude of signal is 1% of (max-min).

If your setpoint is 35°C (then "350") and if you want +/- 3°C (="30"), then you can use measurement min = 3000 and max = 6000.
(1 % of max - min = 30)
