+===== Why should I do that? =====
 Couplers connect the motor to the threaded rods that move your z-axis up and down. If the motor and the rod are not perfectly aligned, the rotation of the motor will apply force to the rod and push it into x and y direction. This leads to the so called **z-wobble** and slightly shifted layers.
 ===== The correct installation =====
-It's simple: The middle of the coupler must be flexible. So don't insert the rods until they touch each other, just insert the rods on both sides for **5mm**. They have to get in touch with the screws, but they dont need go in all the way.
