⬢Carefully turn the printer so that the side with the Filament sensor (with 3 PTFE tubes) is facing you.
⬢Insert the first M4nEs nut into the front support extrusion (with the orange plastic cover). Insert the side with the spring (metal plate) first, then push the nut inside.
⬢Insert the second and the third M4nEs nut into the extrusions as described in the picture.
⬢The M4nEs nuts are free to move, you can adjust the position as you want. But remember, the nuts must be slightly pushed in to smoothly move. Anyway, we recommend approximately the same position as you can see in the picture.
