G1 E-2 F300 ; retract filament even more

G1 X20 ; move X axis close to tower but hopefully far enough to keep the fan from rattling
G1 Y120 ; move bed forward for easier part removal
M84 ; disable motors
G4 S360 ; keep fan running for 360 seconds to cool hotend and allow the fan to be turned off - adjust to your needs
M107 ; turn off fan. Don't use M106 S1. Using M106 S1 may prevent the fan from turning on for the following print. Some say M107 doesn't work for them but if the hotend is below 70 degrees it should work
