My custom Klipper macros

Check the macro's description for what it does and how to use it

Some extended macro descriptions / help

• START_PRINT

  • Slicer configuration

    • SuperSlicer

      Printer Settings → Custom G-Code → Start G-Code

      ;Klipper start print macro
      START_PRINT HOTEND={first_layer_temperature[initial_extruder]+extruder_temperature_offset[initial_extruder]} BED={first_layer_bed_temperature} RELATIVE_E_MODE={use_relative_e_distances} PROBE=true PROBE_AREA_START={first_layer_print_min[0]},{first_layer_print_min[1]} PROBE_AREA_END={first_layer_print_max[0]},{first_layer_print_max[1]}

    • Cura

      Note: PROBE_AREA_START and PROBE_AREA_END rely on a non-official Cura plugin which I haven't tested.

      Settings → Printers → Machine Settings → Start G-code

      ;Klipper start print macro
      START_PRINT HOTEND={material_print_temperature_layer_0} BED={material_bed_temperature_layer_0} RELATIVE_E_MODE={relative_extrusion} PROBE=false PROBE_AREA_START=%MINX%,%MINY% PROBE_AREA_END=%MAXX%,%MAXY%

• END_PRINT

  • Slicer configuration

    • SuperSlicer

      Printer Settings → Custom G-Code → End G-Code

      END_PRINT ;Klipper end print macro

    • Cura

      Settings → Printers → Machine Settings → End G-code

      END_PRINT ;Klipper end print macro

• BEFORE_LAYER_CHANGE

  • Slicer configuration

    • SuperSlicer

      Printer Settings → Custom G-Code → Before layer change G-Code

      BEFORE_LAYER_CHANGE
      ;{layer_z}

    • Cura

      Extensions → Post Processing → Modify G-Code → Add a script → Insert at layer change

      BEFORE_LAYER_CHANGE

• SAFE_RETRACT

  Safe retract relies on properly set firmware retraction values. As such, it can be helpful to set the values using a custom g-code command in your slicer

  • Slicer configuration

    • SuperSlicer

      Filament Settings → Custom G-Code → Start G-Code

      ; Filament gcode
      SET_RETRACTION RETRACT_LENGTH={retract_length[current_extruder]} RETRACT_SPEED={retract_speed[current_extruder]} ;UNRETRACT_EXTRA_LENGTH={retract_length[current_extruder]} UNRETRACT_SPEED={retract_speed[current_extruder]}

• Pressure Advance

  This doesn't relate directly to a specific macro here, but it can also be useful to set your per-filament pressure advance values using custom g-code in your slicer as well

  • Slicer configuration

    • SuperSlicer

      Filament Settings → Custom G-Code → Start G-Code

      ; Filament gcode
      SET_PRESSURE_ADVANCE ADVANCE=0.075 ; SMOOTH_TIME=pressure_advance_smooth_time
