What size/type of stepper motor would have the power to drive a cutter to cut a 14ga piece of wire? The cutter is driven on a threaded rod to use mechanical advantage. I have a mock-up of the system, including small steppers and control software. The steppers are currently controlled by 2 5803's, with input from a PC via parallel port. The 5803's will only carry 500mA per phase, so I am pretty sure I will need a different controller. Any suggestions would be appreciated. Peter Cauchy
