Hi! I've never touched an arduino but I'm wondering if it mightn't be the perfect platform to rebuild our laboratory stretch-rack that blew up (litterally) last month. Essentially we need two stepper motors, attached to screw-shafts, to stretch thin strips of plastic. Does anybody know if they'll be strong enough? could a couple of stepper motors with torque ~78.4mN.m tear apart a 10x30 mm bit of plastic bag?
