+## This is a simple include for the Nevermore. To use it with your printer, edit
+## the pin definition in line 16 so it matches your printer.
+## What you get:
+## - a generic fan "Nevermore" which is adjustable in GCODE and in Mainsail/Fluidd
+## - Commands in your 12864-controller to turn the fan on/off or adjust in 10%-steps
+## - a Macro to turn the fan off some time after the print.
+##
+## Slicer integration: Add "SET_FAN_SPEED FAN=Nevermore SPEED=1" in your start-macro
+## (or less fan depending on your needs, like SPEED=0.8)
+## in your end print code, add "UPDATE_DELAYED_GCODE ID=filter_off DURATION=180"
+## this keeps your Nevermore running for 180s after the print finishes to clean the chamber a bit more.

+## Nevermore - FAN5 on Octopus
+## Adjust if you use a different board or a different terminal.
