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.
