I am a bit puzzled on the stepper wiring.
My Nema's'that come with Rostock mini Delta have red, blue, green and black wires.
On the Ramps wiki, the order of those is prescribed as : Red-Blue-Green-Black from left to right, with the D10 on the left side.
However, I ordered a set of stepper extension cords , both ends fixed connectors, in which the order is: Red-Black-Blue-Green.
On the Nema specs page i read:
These specs do make sense with the mixed phases in the new extension wires: when I reverse the connector, the paired phase and return are kept together, even when not side by side.
As this rotatable connector feature is also the fact on Ramps (as I recall to have red somewhere), this means that on Ramps both Phase & returns are next to each other, instead of mixed as in my extension wires.
So I can not solder color on color from the Nema's to the extension cords ?
