Today I tried to PWM the stepper motors when they are idle. There are several problems with this. First and formost is that any pwm-ing on the steppers results in a high pitched sound that I can’t stand. It’s probably caused by some vibration, so the benefits of lowering the power (reducing heat) is probably offset by the vibration and any wear and tear it may cause.
The second thing...
