Check your X-end-motor printed part for following holes. If they are present, please follow this step, otherwise skip to the next one.
⬢You can also check the version of the printed X-end-motor, this step is valid for B6 and higher.
⬢M3nS nut (1x)
⬢M3x18 screw (1x)
⬢Insert nut and screw in the holes. For now, we need the screw just to hold in place. Tighten the screw, until its head almost reaches the surface of the printed part. We will adjust the final position later.
⬢Make sure the M3x18 screw is not visible in the marked hole (see the last picture) as it will block other screw in future step. If you can see the screw in the hole now, please release it slightly.
