HAPPY BIRTHDAY GCODE REPRAP MARLIN SPRINTER ETC
thingiverse
Adapted from TeamTeamUSA gcode to work on pronterface and marlin firmware on any reprap. Had to delete the bracketed out lines from the original code for it to run correctly. It makes the Z axis motor hum the 'happy birthday' tune, it doesn't move any of the axes significantly. HAVE FUN. Instructions Run on any standard 3d printer I think. I have it running using pronterface on marlin firmware
