Motorized Camera Track Dolly Slider

To accurately position a Canon 70D DSLR camera under computer control, a motorized camera track dolly slider (or CNC linear camera stage), is built from machined parts and parts from Misumi, Schneider Electric, and Canon. The linear motion portion is built using a ball screw and linear rail. In this first video, the design is presented in SolidWorks, and then Fusion360 is used to program a CNC mill to make the custom parts. The parts are then machined along with a discussion of the machining decisions. In second video, the linear stage is assembled and tested. There are also a couple related videos, one on machining a socket to torque the ball screw retaining nut and another on machining the NEMA 17 motor mounts. Below is a playlist containing all these videos.
