    Frameless Laser Harp

    I too experienced this and solved it with a bit of a hack tbh. I added a push button that starts the main program so when I first turn it on there is just a single beam. I then added a knob to the axle of the motor so I could turn it to set the correct start position for the mirror. There's probably a far cleverer way of doing this but hey, it works!
