General Discussion

i cant figure where i went wrong
M106.cfg code

[gcode_macro M106]
rename_existing: G990106
gcode:
{% if params.S is defined %}
		{% if params.S|int == 255 %}
			{% set realspeed = 1 %}
		{% else %}
			{% if params.S|int == 0%}
				SET_FAN_SPEED FAN=LHfan Speed= SPEED=0
				SET_FAN_SPEED FAN=RHfan Speed= SPEED=0
			{% else %}
				{% set realspeed = 0.003921params.S|int %}
			{% endif %}
		{% endif %}
	SET_FAN_SPEED FAN=LHfan Speed= SPEED={realspeed}
	SET_FAN_SPEED FAN=RHfan Speed= SPEED={realspeed}
{% else %}
	SET_FAN_SPEED FAN=LHfan Speed= SPEED=1
	SET_FAN_SPEED FAN=RHfan Speed= SPEED=1
{% endif %}

Send: status
Recv: // File contains parsing errors: /home/pi/macros/M106.cfg
Recv: // [line 4]: ‘{% if params.S is defined %}\n’
Recv: // [line 17]: ‘{% else %}\n’
Recv: // [line 20]: ‘{% endif %}\n’
Recv: //
Recv: // Once the underlying issue is corrected, use the “RESTART”

Are those 990 correct?

Also, you have to indent:

[gcode_macro M106]
rename_existing: G106
gcode:
    {% if params.S is defined %}
        {% if params.S|int == 255 %}
            {% set realspeed = 1 %}
        {% else %}
            {% if params.S|int == 0%}
                SET_FAN_SPEED FAN=LHfan Speed= SPEED=0
                SET_FAN_SPEED FAN=RHfan Speed= SPEED=0
            {% else %}
                {% set realspeed = 0.003921params.S|int %}
            {% endif %}
        {% endif %}
        SET_FAN_SPEED FAN=LHfan Speed= SPEED={realspeed}
        SET_FAN_SPEED FAN=RHfan Speed= SPEED={realspeed}
    {% else %}
        SET_FAN_SPEED FAN=LHfan Speed= SPEED=1
        SET_FAN_SPEED FAN=RHfan Speed= SPEED=1
    {% endif %}

Maybe you also should use spaces instead of tabs.

M106 does not exist in klipper so i dont need the rename.
so i remove the rename and tabs and indent properly.

[gcode_macro M106]
gcode:
    {% if params.S is defined %}
        {% if params.S|int == 255 %}
            {% set rs = 1 %}
        {% else %}
            {% if params.S|int == 0%}
                SET_FAN_SPEED FAN=LHfan Speed= SPEED=0
                SET_FAN_SPEED FAN=RHfan Speed= SPEED=0
            {% else %}
                {% set rs = 0.003921params.S|int %}
            {% endif %}
        {% endif %}
        SET_FAN_SPEED FAN=LHfan Speed= SPEED={rs}
        SET_FAN_SPEED FAN=RHfan Speed= SPEED={rs}
    {% else %}
        SET_FAN_SPEED FAN=LHfan Speed= SPEED=1
        SET_FAN_SPEED FAN=RHfan Speed= SPEED=1
    {% endif %}

however after all that i get the following in the terminal window

Send: status
Recv: // Error loading template 'gcode_macro M106:gcode': TemplateSyntaxError: expected token 'end of statement block', got 'params'
Recv: //
Recv: //
Recv: // Once the underlying issue is corrected, use the "RESTART"
Recv: // command to reload the config and restart the host software.
Recv: // Printer is halted
Recv: // Klipper state: Not ready

the above should read

  {% set rs = 0.003921*params.S|int %}

i guess multiplication is not assumed. the error code is pretty vague though.but the formula error causes the whole IF…ELSE…ENDIF statment to fail

thank-you for the help
