1.10 - Install the Motor Mount on the T-Slot Support. You’ll want to insert two #6-32 Nylon lock
nuts as shown. Use a #6-32, 1” flat head machine screw to attach the Motor Mount to the T-Slot
Support. Do not tighten it down! Drive the screw in only a bit so it engages the Nylon. This will be
tightened down when the assembly is installed in the base plate.
1.11 - You may wish to install the stepper motors (Steps #4 & #5 below) and their connectors at
this point. It's easier to install the stepper motors on the X & Y axes without the doors in place. (The
connectors for the X and Y axis motors can be connected directly to the wires on the stepper motors,
but the Z axis requires a short extension to reach the electronics bay.)

1.12 – Install Tri Support assemblies into the base plate. Before mounting in the base, install the
#6-32 nylon locknuts - doing them at this stage is much simpler than when the assembly is set in the
alignment notches in the base. Also note that the locknuts may not be the same dimension as the
notches they go into. They may be slightly over or under-sized depending on how they're measured.
The nuts will try to rotate and it makes the fit difficult. If the nut doesn't fit easily, turn it to a new set of
faces until it fits properly.
