Useful Things to Add to Your PRINT_START/END¶

PRINT_START¶

Turn on Active Toolhead During Print¶

Add the following to your PRINT_START macro to turn on your toolhead's nozzle LEDs. The nozzle_led_idx variable in your AFC_extruder config section needs to be set up for the macro call to work correctly. All tools also need to be passed in from your slicer correctly. See the Slicer Gcodes section on the DraftShift Design website.

{% for tool_nr in printer.toolchanger.tool_numbers %}
    {% set tooltemp_param = 'T' ~ tool_nr|string ~ '_TEMP' %}
    {% if tooltemp_param in params %}
        M109 T{tool_nr} S{params[tooltemp_param]} D120
        AFC_SET_TOOLHEAD_LED MAP=T{tool_nr} TURN_ON=1
    {% endif %}
{% endfor %}

PRINT_END¶

Dock Active Toolhead Once Done Printing¶

To dock the current active toolhead once done printing, define the following as a standalone macro and then call _DOCK_TOOL from within your PRINT_END macro. This is only valid if using klipper-toolchanger. Thanks to Nic335 from the DraftShift Design team for this macro.

[gcode_macro _DOCK_TOOL]
gcode:
    UNSELECT_TOOL RESTORE_AXIS=""
    G0 Y330 X175
    G0 Z 10
    M107

Turn off Toolhead LEDs Once Done Printing¶

To turn off all toolhead LEDs once done printing, add the following to your PRINT_END macro.

{% for tool_nr in printer.toolchanger.tool_numbers %}
    AFC_SET_TOOLHEAD_LED MAP=T{tool_nr} TURN_ON=0
{% endfor %}
