Most inexpensive 3D printers use a type of lead screw to move some part of the printer in the vertical direction. A motor turns a threaded rod and that causes a nut to go up or down. The printer part ...

This file type includes high-resolution graphics and schematics when applicable. Lubricants on ball screws are as important to their performance and life as are their operating loads, speeds, ...

A few simple tips for maintaining accurate, reliable ball screws. It's relatively simple to determine the lead accuracy of a ball screw before you buy it. Just ask the manufacturer and get a protocol.

A lot of the projects we feature here on Hackaday engender the classic “build versus buy” argument. We’ve always been puzzled by that; if anyone can appreciate the sheer joy of making something rather ...
