 The factory settings cause indefinite temperature swings of ±5ºC with a period of 60-80 seconds. M303 (PID auto-tune) causes the printer to crash/​reboot in firmware versions preceding 18.37. In 18.37 and later firmwares, M303 works, but the results are on par with the PID settings from the factory. ​ The stored value of the I parameter is 1000th of what it actually uses and autotunes to, therefor after M301 autotune you will need to manually reset the M301 I value to 1/1000th of what the autotune reports. The factory settings cause indefinite temperature swings of ±5ºC with a period of 60-80 seconds.
