My information is that stepper motors that are microstepped require 2 times their rated amperage be available as both poles could be energized at once at a low setting. Is their a setting lower than 1/8deg where this will not occur or is it just better to buy a higher amp power supply. Thanks
V=I*R For example a 3A motor (max rating, not recommended) with 3v coil rating. Needs 9w per coil * 2 coils =18w per motor. * 4 motors = 72w. Account for losses in the drivers, budget way over to double. 150w will do fine. Microstepping lowers torque but results in smoother motion that makes for less stalling, better acceleration, less vibration. Doesnt change the current draw. Modern chopper style drivers are awesome
