M104 S0 ; turn off hotend/extruder heater
M140 S0 ; turn off bed heater
G91 ; Switch to use Relative Coordinates
G1 E-2 F300 ; retract the filament a bit before lifting the nozzle to release some of the pressure
G1 Z1 ; raise Z 1mm from current position
G1 E-2 F300 ; retract filament even more
G90 ; Switch back to using Absolute Coordinates

G1 Y115 ; move bed forward for easier part removal
M84 ; disable motors
G4 S600 ; keep fan running for 600 seconds to cool hotend and allow the fan to be turned off
M107 ; turn off fan. Some say M107 doesn't work for them but if the hotend is cool enough it should work
;M106 S1 ; turn off fan. Remove the semicolon in front of M106 if M107 doesn't work for you
