No longer lurking, stepper motor question.

[irving2008]

Do you have a datasheet for those motors? The 112 designation seems to be a special, it's not in the catalogue. They are 200 steps/rev. Low torque motors by cnc standards. You got these off fleabay @ £6.50 each?

What L298 driver boards are they? Most of the shield ones have uselessly small heatsinks.

Sorry to say this, but you'll need to treat these steppers and maybe the shields as a throwaway learning experience. At best you can create a 'learning toy' but for any real cnc work they're useless.

However, happy to help you 'get them turning'. What electronics expertise do you have and what test equipment do you have to hand?

First thing we need to do is try and work out what spec those steppers are and whether you have wired them up right.
