IDEX Parts cooling fan turned off

SiC_FPV · February 25, 2022, 8:40pm

I have an IDEX printer, and I want to activate the fan of the second extruder when the tool is activated, I saw a Macro here, so I just copied, but still not working. So, basically something is sending the SET_FAN_SPEED FAN=extruder1_partfan SPEED=0 when the tool changes.
klippy.log (931.1 KB)
Should I write something on the GCode of the Tool Change? I tried but did’t worked. Appreciated

Hi @SiC_FPV try this

## add to T0 macro
SET_GCODE_VARIABLE MACRO=FAN_VARIABLE VARIABLE=active_fan VALUE=0
CARRIAGE_PRINT_FAN

Damn bro! You’re the best!!! The first one worked perfect. And this one will do it as well!!! Klipper community is the best much appreciated!

DrumClock · March 18, 2022, 6:33pm

I’m not the best … these are others who help learn Klipper

Do you use hybrid_corexy or hybrid_corexz kinematics?

it could work this:

### Active FAN for carriage
    
    
     {% if printer.dual_carriage.active_carriage == "CARRIAGE_0" %}  
        ### FAN on carriage X1       
        SET_FAN_SPEED FAN={fan} SPEED={fan_speed}
        SET_FAN_SPEED FAN={fan1} SPEED=0

     {% elif printer.dual_carriage.active_carriage == "CARRIAGE_1" %} 
        ### FAN on carriage X2        
        SET_FAN_SPEED FAN={fan} SPEED=0
        SET_FAN_SPEED FAN={fan1} SPEED={fan_speed}
    {% endif %}```

Hi I’ve tried to use your macros but I receive this error:

Any suggestion? (please)

Hi, this is probably my first macro.
I am currently using universal macros for various printer cfgs.
Info here: GitHub - DrumClock/my_config

The advantage is that the names of the fans are loaded from printer.cfg and also the switching logic for IDEX, which is dependent on the type of kinematics, is redesigned.

Try new macros, otherwise you’ll have to find the problem yourself because it doesn’t have your complete cfg.
