K8200: 3 of my engines run in the wrong direction

I finished editing my 3D K8200 printer : ... p-511.html

The computer and the printer communicate well but the XYZ engines work all 3 in the opposite direction, I checked my connections, they correspond to the assembly scheme. Anyone know which wires to reverse to keep the motors spinning in the right direction?

it depends if it is unipolar or bipolar motors, but from memory it seems to me that the principle is the same: it is necessary to reverse the order of the phases (as on a tri engine)
Basically connect A instead of B and vice versa.

Thank you Forhose!
I reversed two wires a bit random and it works, same thing for 2 other engines and everything rolls. I do not know much about motor. He takes out four sons, so two negatives and two positives .... chance may be a bit risky!
