Ender 3 MicroSwiss Hotend PID parameters

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
  • RunĀ M106 P0 S255 to turn on the first fan
  • RunĀ M106 P1 S255 to turn on the second fan
  • Run PID autotune using M303 E0 S210 C8

then proceed like shown above.
