This is part #? in a list of postings on the electronics of my CEVO. The full list can be found here . The topic of this post is how to wire the stepper motor to the RAMPS. I am pretty sure most newer motors are the same, and yet I had difficulties to find a simple guide on how to do the wiring. The most referenced guide is https://reprap.org/wiki/Stepper_wiring , and that was indeed the generic guide I used as reference. I am however quite sure you can just follow my guide below.
