Continuing the discussion from Inventables Blog: Pre-Order Your X-Controller Today!:
@EliasPolitis points out that the picture of the Y2 stepper connector “seems to have one of its coils (black/green) flipped on the Y2 connector.”
@sketch42 says that “it is black, green, white, red for all of the axis except for Y2 where it is black, green, RED, white”
Can Inventables chime in here and let us know which is the correct wiring for Y2?
According to a simple stepper motor diagram, maybe it doesn’t matter, just so long as you do one pair or the other.
