Este es el motor de paso y driver que use pero lo ago devuelta voy usar unar driver y motor mas grande y una fuente mas grande y seperada. Con este motor/driver si pude cortar acero. (this is the driver and stepper motor that I used but If I could do it over I would use a bigger stepper motor and driver along with it's own bigger power supply although I was able to cut soft steel with this no problem).
