Hi everyone, I'm in the process of building a CNC machine. It is controlled by 3 stepper motors controlled by a driver board. Each motor uses 3A, and my board can only handle 36V. How do I drop my 42V power supply to 30V? -I can't find a high amperage, 30V linear regulator. -A bunch of diodes in series to drop the voltage would not work because the current will drop when some motors are not in use.
