Assemble the motors
For this section you will need:
- 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.
- Get a 2.5mm 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 with two M4x6mm button head screws
- Repeat for Y and Z actuators. For the Z actuator use the rectangular slot to the left of the actuator.
