+==== Steps to PID Tuning ====
+Execute the PID_CALIBRATE for the extruder with your typical print temperature, here we're using 220 as that's what we mostly print our PLA. Watch the extruder temperature settings and the graph while it takes a few minutes to evaluate how the heater performs. It will output three parameters.
+<code>
+PID_CALIBRATE HEATER=extruder TARGET=220
+// PID parameters: pid_Kp=21.037 pid_Ki=0.917 pid_Kd=120.698
+// The SAVE_CONFIG command will update the printer config file
+// with these parameters and restart the printer.
+</code>
+Add the three values to the EXTRUDER stanza in [[printer.cfg]]
+<code>
+[extruder]
+control = pid
+pid_kp = 21.037
+pid_ki = 0.917
+pid_kd = 120.698
+</code>
