5.2.3.1 Building the bulk of the frame
When you build this, make sure you do not tighten down any of the bolts—it should be super
loose to start. The additional parts needed to fabricate the rest of the frame with your two tri-
angles are three 440 mm M8 threaded rods (the long ones), 16 M8 washers and 16 M8 nuts.
Put the frame together with the long rods as shown in Figure 5.6 . You are already done with
the frame! Nice work.

5.2.4 The y -axis (back and forth)
The y -axis consists of two sides each consisting of a pair of threaded rods with only slight dif-
ferences in what is placed on these rods. The assembly of the top rods is identical, whereas
the lower rods are assembled slightly differently. Note the distinction between motor end and
idler end—the motor end has additional nuts and washers on the lower rod.
5.2.4.1 Building the y-axis upper rods
Sometimes the rods are hard to thread. If you are having difficulty threading, chase the
threads with an M8× 1.25 die or jam a pair of nuts on one end of the threaded rod and use
wrenches to increase the amount of torque applied.
