Custom Profiles: Fan controls

    "doFanCommand"

    True/false

    Set "doFanCommand" to "true" to insert a command to turn on an active cooling fan during a build. The "fanLayer" setting (see below) determines where in the toolpath this command will be inserted. If the "doFanCommand" setting is set to "false," the "fanLayer" setting will be ignored.

    "fanLayer"

    Integer

    The "fanLayer" setting specifies at what layer the slicer will insert the command to turn on the active cooling fan. If the "doFanCommand" setting is set to false, this setting is ignored.

    "fanDefaultSpeed"

    Percentage

    “fanDefaultSpeed” sets the power level for the active cooling fan. If your MakerBot 3D printer does not have an active cooling fan, this setting will not be used

    "weightedFanCommand"

    Integer, [1, 100]

    Allows you to set an extruder fan speed. MakerBot 3D printers do not use this setting.

    "doFanModulation"

    True/false

    Fan modulation allows the active cooling fan to turn off or slow down at different times during your print. When “doFanModulation” is set to “true,” the fan will turn off during travel moves and very short periods of extrusion. When “doFanModulation” is set to “false,” the active cooling fan will spin at a constant speed throughout your print.

    If you are slicing models for use with a MakerBot 3D printer without an active cooling fan, this setting will be ignored.

    "fanModulationWindow"

    Seconds

    When “doFanModulation” is set to “true,” the active cooling fan will turn off every time filament is retracted. When the fan turns on again is determined by the “fanModulationWindow” setting in combination with the “fanModulationThreshold” setting.

    After each retraction, the slicer will analyze all upcoming moves within the period of time defined by the “fanModulationWindow” setting. When the ratio of moves with extrusion to moves without extrusion (travel moves) is higher than the value set in the “fanModulationThreshold” setting, the fan will be turned back on.

    "fanModulationThreshold"

    Decimal, ratio

    When “doFanModulation” is set to “true,” the active cooling fan will turn off every time filament is retracted. When the fan turns on again is determined by the “fanModulationThreshold” setting in combination with the “fanModulationWindow” setting.

    After each retraction, the slicer will analyze all upcoming moves within the period of time defined by the “fanModulationWindow” setting. When the ratio of moves with extrusion to moves without extrusion (travel moves) is higher than the value set in the “fanModulationThreshold” setting, the fan will be turned back on.
