Here’s an interesting experiment that attempts to measure the quality of a linear rail by using a form of visual odometry, accomplished by mounting a camera on the rail and analyzing the video with ...

In the early days of 3D printers, most builds used smooth rods and bearings that rode on them. But these days, printers are shipping with either V-slot extrusions with Delrin wheels or linear rails.

The RGS/RGW linear-rail system includes a 180° folded-over motorized design. Components of the foldedover system include the stepper motor, belt and pulley, precision leadscrew, bearing supports, and ...
