This is a C-Beam based router with V-rails used for the bed, a Sherline spindle with Jacobs chuck, closed loop stepper motors on every axis and an offline 4-axis CNC controller. A U-channel was created to guide the drag chain on the X-axis.

C-Beam based CNC with Rack & Pinion (for the X Axis) and lead screws (for the Y Axis)

Need to build a machine that accurately positions objects for processing by a computer vision algorithm? Here is an example of a machine that does that for a ball trajectory application. The black anodized V-rails work well for applications in optics and imaging where the machine needs to stay out of the limelight.
