You can now attach the idler motor plate to the motor mount plate using (2) #4 x 1/2" screws. The plate can be tilted into position. You will then need to align the bosses of the plate with the bearings and press the plates together.

Secure the assemblies to the laser cut Top Base Plate with the 6-32 x 1" screws. You CAN fully tighten these screws at this time.

Perform this operation for each of the three assemblies.

Route the wires around the top assembly as shown. All wire will pass the hole in the idler plate for containment. The image has arrows indicating the direction that the wiring is traveling.
