    A bleed resistor might be useful while you are testing, but once you have a driver or two wired to the power supply, they look like a waste of time. When I checked my machine, the stepper driver power supply was down to a few volts within seconds of cutting power. Any resistor that drains down faster than that is going to need to be a fairly high wattage item, and is going to produce more heat than you probably want in the control box.
