Assemble the motors

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 x and y 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 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 with two M4x6mm button head screws
• Repeat for y-actuator

Step 3: Attach the z motor

• Attach a motor to the z-actuator of the seperate z-actuator in the same way as they x and y actuators
• Feed the motor cable through the rectangular slot to the left of the z actuator on the main body
• Attach a cable tidy cap to the motor lugs of the z-actuator of the main body
