Marlin pid autotune. Step 2: Try a PID Autotune. To run a PID Autotune, just start by sending this for your first hotend to enforce a 3-cycle PID tuning for the 200 °C region: M303 C3 S200. For your second hotend, you'd send M303 C3 E1 S200 - the E-value is 0-indexed and defaults to 0 for the first hotend, so E1 is the second hotend.
