stepper motor

I'm new to Arduino and microcontrollers in general. I've had an Uno for about a half of a year. Using the diagram posted by Tom Igoe (link below), I made an H-bridge to allow me to control a stepper motor with my Arduino. I made the mistake of buying an Arduino's R3 motor shield, not realizing that the design was so new. Come to find out there is little to no documentation to be found on it. My problem is that I have no clue (other than mounting the shield) on how to wire in the stepper motor and what changes to make to the sketch which works with my H-bridge.

Hello,

I have the following:

EasyDriver stepper motor driver

Bi-Polar stepper motor 6 wire

I am using Red/White and Yellow/Black, which means I'm using half coil.  My understanding is this allows me to use the full current (and presumably have more holding strength).

Hi LMR!

I have a teeny problem - I'm playing with stepper motors for my next robot, the plan is to have an 18M2 sending serial packets to a pair of 08M2s which each will control one stepper, to save outputs on the 18.

My problem is this, when I have the 18 running into the L293 driver the motor runs perfectly, but when I use an 08 nothing happens and it gets hot (I fear the magic smoke)...

Hi, just a basic question, but I have a stepper here with four wires coming out of it one of which is gnd,

Is it a three or four wire Stepper motor?

I am slightly confused so any anwser would be appreciated,

Cheers

I'm in the process of building a CNC machine right now and would like a little help from the experience ones.  Right now I have $250 saved up and counting.  I'm trying to figure out what to do about stepper motors, power supply, and motor controller.  I didn't know if it be best to just buy a package that have it all in one and what would you recommend.

I'm building a 3D printer and I'm a little over my head. Right now I'm trying to make sure most of my components play nice with each other with some simple code and only one motor.  Here's my set-up:

I have a seeeduino mega. More on the pinouts later. It's being powered via USB and I don't know if that's okay.

Well, yesterday i was cleaning the basement of one of my friend's house when i found this:

A very good looking box with a lot of interesting stuff in! Motors, mechanics, gears, belts...and whatever people can drem up! Perfect for some cool robotic projects! So i brought everything in my house and i started testing it. I have no idea of where all this stuff came from, it seems a sort of photocophy machine, or something like that. All the guesses are welcomed!

hi, ive bought a stepper motor which has totally six wires...but i dnt know how to run it continuosly..

pls help me in dis and tel all d component details and sequences to run continuously...

thnks 

I ripped apart a couple of flat bed scanners looking for gears. So I have two stepper motors in my kit box that takes up valuable space. If anybody got inspired by this and want to give stepper motors a shot, just give me your adress and I'll send one your way for free in about two weeks (vacation atm).
