correct mounting position. (If you make a mistake, unbolting a motor and ro-
tating it takes only a minute.)
The first two motors you'll attach are for the X axis and the Z axis. The X-axis mo-
tor is used to move the print bed left and right (when looking at the Simple from
the front). The Z-axis motor turns an item called a lead screw. Notice in Figure 3.7
that the Z-axis motor has its wires going through the precut rectangular hole. Also
note that the instructions point out the two small circles that run up the left edge
of the laser-cut piece of wood. This bit of information will help you attach the Z
motor properly. If you mount it on the wrong side, the Z-motor axle (the metal rod
that you can turn with your fingers) will have the two small circles on the right
side.
Figure 3.7 The Z-motor's wires are inserted up through the rectangular hole.
After the X and Z motors are attached to their respective wood pieces, it's time to
assemble the base. You can see in Figure 3.8 that the base is partially assembled
(and the bearings that were slightly hidden in Figure 3.4 are now visible); it still
needs the right side (if viewed from the front) and the two 10” metal rods inserted
into the two laser-cut circles.
