@tag16c thanks a lot !!! I have understand your circuit . You can move the mirrors 20,000 times per second ( if the galvos/hardware can handle it) thats right? And JamesCooper and the peachy team are do'nt working with 20kHz audio out, instead they are using a lower frequency sine wave and handle the amplitude peak with cap and diode. thats right ? For the printer they don't need that fastby Dino - Polar Machines, SCARA, Robot Arms

@ Spelljammer Great idea ! Looks pretty cool. Is it possible to compensate that pivot-point problem only with software ? Are you not afraid that if a coil is energized the magnet will be attracted and "snap" to the coil and that's it. Cause the magnet could reach the coil without any obstruction? Or i'm totally wrong? @ tag16cby Dino - Polar Machines, SCARA, Robot Arms

Hi to everybody, a idea of another concept to build a low cost galvo. In this way i use only one mirror and the problem of the axis of the Pivot-point.is solved. I hope this works, i have ordered a laser and a first surface-mirror and when it arrieved i try to build and test it. .... any bugs in my thoughts ???? ... let me know !!! ...
