There is no color standard and even the labels on spec sheets vary.
the best thing you can do is get a spec sheet.  try googling the motor info.



Typicaly you will have a+ a- b+ b-

there may be labeling on the board as well.
sometimes techs need to be investigators.


as far as boards avoid cheap offshore imports these are the boards that case fires. either go USA built Europe import or at least a reliable importer.

So, I removed the lid and then I saw that the stepper motor wires have 4 different colors (red, blue, yellow, white).
Can someone tell me the meaning of each color?
