Improve Hotend Cooling

By default at the end of a print, the hotend is cooled by its fan which runs at 100%.

By making this change, the hotend fan speed will be reduced to 80% and the side fan will also be enabled at 40%. This allows faster and quieter cooling.

Note

This procedure must be repeated after restoring the printer to factory settings.

Configuration

  • Open gcode_macro.cfg file:

    • On original Fluidd Web Interface go to Configuration icon on the left side.
    • On original Mainsail Web Interface go to Machine tab on the left side.

  • Search macro named [gcode_macro WAIT_TEMP_START] and replace it by this one:

    gcode_macro.cfg
    [gcode_macro WAIT_TEMP_START]
gcode:
  UPDATE_DELAYED_GCODE ID=wait_temp DURATION=1
  SET_PIN PIN=fan0 VALUE=210
  SET_PIN PIN=fan2 VALUE=210

  • Then, search macro named [gcode_macro WAIT_TEMP_END] and replace it by this one:

    gcode_macro.cfg
    [gcode_macro WAIT_TEMP_END]
gcode:
  UPDATE_DELAYED_GCODE ID=wait_temp DURATION=0
  M106 P0 S0
  M106 P2 S0

  • Then, click on SAVE & RESTART button in the top right corner.
