Nema 17 wiring help
May 01, 2015 11:55PM
Hey guys I bought some new nema 17's and they only included these images:



Which ones go to 1A, 1B, 2A and 2B?

I hooked them up like this:

Black - 1A

Green - 2A

Red - 2B

Blue - 1B

And my motors vibrate back and forth when I try to use them. Last time I had this problem I just messed around until I got it right, this time I want to understand what is right, can you help me with this please?

As pictured its two coils

One coil goes on pins 1 and 2 (2b and 2a) and the second coil to pins 3 and 4 (1a 1b)

With 4 wire steppers it doesnt matter wich end of the coil goes to what pin, so long as both coil ends are togeather on the left or the right two pins.
The motor direction is just reversed, wich you can fix in firmware, or just flip the entire plug around 180 degrees.

So in your case swap black and red wil fix it.

Ahh for some reason I paired the A's abd B's instead of the 1'2 and 2's, thanks!!
