SET_IDLER.cfg

# Use SET_IDLER to control idle timeout and behavior
# 
# The default behavior is to only turn off the extruder heater.
# Set a parameter to 1 to keep that component on and 0 to turn it off.
# 
# Examples:
# 
# Power off printer after 15 minutes:
# SET_IDLER TIME=900 POWER=0
# 
# Turn off only the bed_heater after 5 minutes:
# SET_IDLER TIME=300 EXTRUDER=1 BED=0
# 
# Turn off only extruder after 1 minute:
# SET_IDLER TIME=60
# 
# Turn off bed and extruder, set chamber, but leave steppers on after (default) 15 minutes:
# 
# SET_IDLER EXTRUDER=0 BED=0 CHAMBER=0 STEPPERS=1 POWER=1
# 
# 
# The CHAMBER section offers several options depending on your configuration.
# 
# The first is my personal config, which sets the chamber fan target to the temperature
# read by my ambient room temperature sensor
# 
# The second is for if you have an active chamber heater.
# 
# The final one just sets the chamber fan to off.
# You could instead set the target to any arbitrary value you like by changing the target on that line
# 
# If you don't have any chamber temperature components, you can just comment out all three options.
