No longer using linear actuators :(

Initially, i thought we'd build the entire contraption using linear actuators. However, i soon realized that linear actuators take up a lot of space when fully retracted. I need a space-efficient solution.

Lead Screws
For now, i'll use a linear actuator for the Z-axis, which controls the depth / force applied to the back. For the X and Y axes, I will use lead screws.

I realize that we need to change the design of the entire contraption because the lead screw on the X-axis especially requires strong end support.
