AON-M2 Machine Calibration
The temperature control of the two hot-ends uses a PID control loop. Seasonal swings in ambient operating temperature as well as changes to the system such as replacing components of the hot-end can change the thermal behaviour system as a whole.
In the Terminal window, enter
M303 C5 E0 S250 U to run the automated PID tuning
process and send
M500 to save the values to EEPROM once complete.
The value of
C determines the count of heating and cooldown cycles and should be set
to 5 at minimum, however you may increase the cycle count if desired. Use
E0 to tune
T0 (left tool) and
E1 to tune T1 (right tool).
The PID values for low-temperature printing (200ºC - 300ºC for materials such as ABS, nylon, and PC), will be different than for high-temperature printing (300ºC - 450ºC+ for Ultem™, PEEK, and other high performance materials).
See M303 for more details.
