Well for what it is worth, I must say you have accomplished a lot more than most Newbies do before they post for help. More than 30% of the time they don't even know what kind of motor they are going to use or how to drive it. One guy posted because he was puzzled because his 2A stepper motor wasn't working with a 9V smoke alarm battery. Can you believe that ? When we told him what the problem was he replied "oh, that can't be the problem because I already tried C & D size batteries...." We got a good laugh
out of that.
