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
• 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).
• Take two self tapping screws and drive them fully into the holes on either side of the shaft. #1 pozidrive screwdriver
• 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 the motor to the z-actuator in the same way as they x and y actuators
• Feed the motor cable down the rectangular slot to the left of the actuator.
