# Proper Pause and Resume Support for use with Filament Sensor
# Source: https://ellis3dp.com/Print-Tuning-Guide/articles/useful_macros/pause_resume_filament.html
#
# Assumes you are using a filament sensor. Comment out lines 27 and 54 if you do not use one. 
# If you do, make sure the filament sensor name is Filament_Sensor in your printer.cfg file.
# Also sets neopixels named "EZNeo_220" to RED on pause then back to white on resume. You can change this on lines 28 and 55 if your LEDs are different. Comment out those lines if you dont have LEDS.
