A friend of mine is using a stepper motor for one of his projects. My question is why does the stepper motor run so slow? I presume that stepper motors are found on printers parts (and they move pretty fast). What can he be doing wrong? He was using ULN2003a in combination with a microcontroller. Im guessing that the inductors found inside the stepper motor arnt charging up quickly. Please help.

I made this machine using stepper motors witch works on X and Y axis what kind of progroming languge and i/o devoice do I need to learn about in order to make it work ?

How much would a stepper motor cost me for my VW Golf 1998? Is this an expensive job and can anyone or any mechancis out there give me a rough price as to how much the part would cost and the labour for changing it? Thanks. Its a 1998 mark 4 1.4 petrol S reg

Also how much weight have people lost using the stepper?? And how quickly will you see results when used atleast 3-5 days a week for about 30 minutes per day?
