controller fan not shutting down
My controller fan is not stopping after the time specified, 120 sec, The only way to stop the fan is to reset the firmware or restart the printer. I have a 2nd controller fan that I've set the overrides on and it continues to run after 120sec as well. It is triggered by the activation of the X stepper motor...although what is the X stepper on a corexy? Any suggestions on what to change/look for to get the fans to shut down after 120sec of no movement? Hmmm, what starts the timer for fan shutdown? Is it the stepper not moving for a set amount of time or is it something else?

The controller fan should be running whenever the motors are turned on, to cool the drivers. If you disable the motors, it will turn off
I want my controller fan to be always on since my electronics are enclosed in a tight box. It's a 12V Noctua running on 24V.
It works fine when it work sbut I want it always on. Current setting below, I run out of ideas:
[controller_fan controller_fan]
Pi fan
See the "controller_fan" section in example-extras.cfg for a complete
max_power: 0.25
shutdown_speed: 0
cycle_time: 0.00001
hardware_pwm: false
kick_start_time: 0.50
idle_timeout: 999999
The ammount of time (in seconds) after a stepper driver or heater
was active and the fan should be kept running. The default
is 30 seconds.
idle_speed: 0.18
heater: extruder,heater_bed
if you want it always on, use a always on fan port instead of the default port
do I have the same set of paramaters also for a "always on fan port" as I have on the "controller_fan" ?
I have a 12V Noctua on a 24V RatRig and I would like to have the ability to control the fan by software.
the other option would be installing the fan using a small DC-DC convertor and that might work also
do I have the same set of paramaters also for a "always on fan port" as I have on the "controller_fan" ?no, the always on fan port is always on. No need for a DC-DC converter that is what the always on fan port is doing
thats how you will quickly kill your noctua
you are right, I had doubts in the beginning but it seems it's still alive after...12months or more. I'm still surprised.
however I think I found a workaround: after END_PRINT I just added in the slicer set bed temp 1C. Since my room is .. a little warmer, it will never reach that temperature. Now, after a couple of hours the print ended, the controller fan is still on. yuhuuuu 🙂
huh
feels like cheating
