>G1 E-1 F300;retract the filament a bit to release some of the pressure
>M104 S100;let the extruder cool down a bit
>M140 S0;turn off bed heating
>G0 X100 Y200;move to waiting position (half x-axis, full y-axis)
>G4 P480000;wait 8 Minutes to cool down
>G0 Z5;move head down
>G0 Y0;push printed part off the bed
>;REMOVE PRINTED PART END
