I did a project connecting Arduino and a Bipolar Stepper Motor. I used 12 arduino pins to make it work. But it’s possible with less.
There is a poor video arduino tutorial: HackLab Arduino - Motor de Passo de Boi Bumbá
And I posted the code here:
Your motor seems to be the same kind, bipolar (4wires).
Mrmeval link is for unipolar stepper.
Bipolar and Unipolar are very different.http://www.cs.uiowa.edu/~jones/step/types.html
Mine was removed from Epson Inkjet Printer, and works with 48 volts. Since I was just testing functionality, all I did was connecting arduino pinout to controller IC, not changing printer boards.
The IC was LB1847:LB1847 Datasheet pdf - LB1847-D.PDF - ON Semiconductor
I don’t know if you can use this one, but datasheet has many useful information. I used it’s table to write the code.
If you’ve removed your motor from printer/fax/other equipment, you can find all you need equipment. If you don’t have any equipment that uses this motor, try finding some canon printer schematics: I know this motor is used on some of themhttp://www.smcelectronics.com/printrep.htm. So you can find the IC controller used by canon. If you know the IC, IC datasheet can show you more.
Read this too:
I’ll try to draw schematics of my project later.
