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?
