Assemble the motors
For this section you will need:
Tools
Printed Parts
- 3 cable tidy caps - - Each cap is a different shape
- 3 small gears
Consumables
- 6 drops of threadlock adhesive

Step 1: Attach the small gears
- Take a stepper motor and a small gear
- Place the motor on the work surface with the shaft pointing up
- Apply a small drop of threadlock adhesive to each side of the motor shaft near the top
- Align the flat sides of the motor shaft with the flat sides of the hole in the gear.
- Push the gear onto the motor with the flanged side downwards (motor side).
- Repeat for the other two motors
Step 2: Attach the motors
Note that each motor has a cable tidy cap that is different. Which cap to use should be apparent from the shape. Motors should be added to the x and y actuators of the main body and the rectangular z-axis. No motor is required on the z-actuator of the main body for an upright microscope.”
- Get a 2.5mm Ball-end Allen key ready
- Feed the cable from the motor through the rectangular wall in the outer wall by the x-actuator.
- Place the motor on the motor lugs with the small gear towards the outside of the microscope
- Check that the small gear and the large gear are meshed correctly
- Take the x cable tidy cap and place it over the motor
- Check that the motor cable is running through the cable tidy rather than pinched underneath.
- Fasten the motor and cable tidy caps to the motor lugs of the x and y actuators of the main body with two M4x6mm button head screws
- Attach a cable tidy cap to the motor lugs of the z-actuator of the main body with two M4x6mm button head screws NOTE: there is no motor attached to the z-actuator of the main body
- Attach a motor to the z-actuator of the rectangular z-axis with two M4x6mm button head screws NOTE: there is no cable tidy cap for the rectangular z-axis
- Repeat for y and z actuators. For the z-actuator use the rectangular slot to the left of the actuator.
