Assemble the actuators

There is one "actuator column" for each of the three axes of the OpenFlexure Microscope stage. These allow you to move the sample in X and Y, or focus the microscope by moving in Z.

For this section you will need:

Step 4: Prepare the actuator

Check actuator position

Step 5: Attaching the viton bands and foot

This is the trickiest part of the microscope build. In this step we will clip bands onto hooks inside each actuator.

If you had problems with this step see [troubleshooting actuator assembly].

Step 6: Seat the foot

Step 7: Repeat this process for Y and Z

Follow the same procedure for the Y and Z axes. Once complete the microscope with assembled actuators should look like this:
