Prologue Note: This manual only applies to the 5-mm acrylic Prusa I3. We have another one that is 8-mm.

As picture is much more helpful than words in assembly manual, so I use plenty of pictures and less word.


Unfold the package and take all the parts out to check the condition of the items.

Note: when connect the other Y-motor, use the 4-pin M-F DuPont cable and pay attention to the directions of the wire. If you connect them reversely, the 2 Z motor will move in different directions.

Look at the colors of the wire.
