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.
