Tuning Nozzle temperature



  • Hi,

    At the start, i have this lines in "config.g"

    [[language]]
    ; Heaters
    M143 S285 ; Set maximum heater temperature to 285C
    M301 H0 S1.00 P10 I0.1 D200 T0.4 W180 B30 ; Use PID on bed heater (may require further tuning)
    M305 P0 T100000 B4607 C8.950070e-8 R4700 ; Set thermistor + ADC parameters for heater 0
    M305 P1 T100000 B4138 C0 R4700 ; Set thermistor + ADC parameters for heater 1
    
    

    and at the star Duet forced me to autotune the temperature of the bed, before starting to use the printer

    the question is

    Is it necessary or recommendable to do autotune at Nozzle temperature?
    How would it be done?

    Putting a line similar to this line in "config.g"

    [[language]]
    M301 H1 S1.00 P10 I0.1 D200 T0.4 W180 B30 
    
    

    How would it be done?

    The M301 commands are for setting PID parameters manually. They should not normally be used any more. Instead, you should send an M303 command manually to run auto tuning, then either use M500 to save the resulting M307 command in config-override.g, or construct a M307 command manually from the results and add it to config.g.
