and want more cooling. If you are getting weak parts that easily break,
you are printing too cool or with too much fan.
Enable Print Cooling
This checkbox will turn on your fan, and display more settings for ner
control of how your printer cools. Uncheck this box if your specic material
does not require cooling at all.
Fan Speed Settings
While enable print cooling is selected, you will have access to fan speed,
regular fan speed, and maximum fan speed.
• Fan speed will limit the maximum speed at which your fan can run.
It is recommended to leave this at 100% and adjust the maximum
and minimum fan speeds to achieve your desired result.
• Regular fan speed will determine the minimum fan speed your
extrusion fan will run after a certain number of layers or height. Your
extrusion fan will increase from 0% on layer 1, to your regular fan
speed at your Regular fan speed at height or layer setting.
• Maximum fan speed will determine the absolute fastest your extru-
sion fan will spin. Your fan speed will range from regular fan speed to
maximum fan speed dependent upon regular/maximum fan speed
threshold.
• Regular/maximum fan speed threshold will be used to determine
how your printer changes between minimum and maximum fan speeds
based on layer time. Any layer that takes more time than dened
here will run the extrusion fan at regular speed. Any layer that takes
less time than this, will scale from the regular fan speed up to the
maximum fan speed.
• Initial fan speed will activate your fan at this speed for the rst
layer. Your fan speed will then ramp from initial fan speed to
regular fan speed over the specied regular fan speed at height
or layer.
