# Fan Speed Slider Plugin Add a slider to control the speed of a parts cooling fan. The default value of the slider is user configurable, however the value doesn't limit the output of the fan during a print, for that you'll have to use your slicer. ![](./image/slider.JPG) *Note: Slider does __not__ follow the speed of the fan. If the fan speed is set via gcode or an LCD panel on the printer, the slider will not respond to the change.* ## Setup Install manually using this URL: https://github.com/ntoff/OctoPrint-fanspeedslider/archive/master.zip
