It took many hours of modelling in SolidWorks and running to the laser cutter and back, but finally the Z axis for the depth-from-focus 3D scanner is completed. Mainly the work was designing parts to adapt components together, like the camera board to the remnants of the micromanipulator, the knob of the Newport 443 Series linear stage to a gear, and the geared motor also to the stage. Activating the motor moves the apparatus up and down beautifully, so I can move on to designing, building, and writing firmware for a motor controller to let me control the scanner mechanics from a computer.
