These are the Hotend PID parameters for my Ender 3 using a MicroSwiss hotend with a MicroSwiss direct drive Extruder:
Marlin Configuration.h
setting:
#define DEFAULT_Kp 29.34 #define DEFAULT_Ki 3.58 #define DEFAULT_Kd 60.08
Set PID values using G-Code and save to EEPROM:
M301 P29.34 I3.58 D60.08
M500
M301 P29.34 I3.58 D60.08 M500
How to run PID autotune
If you want custom values, run PID autotune like this:
- Start with a completely cooled down Hotend
- Run
M106 P0 S255
to turn on the first fan - Run
M106 P1 S255
to turn on the second fan - Run PID autotune using
M303 E0 S210 C8
then proceed like shown above.
