The RepRap Screw-driven Linear Axis
Version 1 *DRAFT*
-- Main.VikOlliver - 25 Nov 2005
1. Summary
This describes how to construct one of the two types of linear axis envisaged for use in the RepRap from FDM'd parts. As with other RepRap components, this axis was designed to be made by the RepRap rapid prototyper itself, and thus consists of standard parts plus rapid-prototyped components. No modifications are required to the standard components.
The axis designed to be stepped back and forth to an accuracy of better than 0.1mm by means of a stepper motor and threaded rod. The axis is designed to transport a carriage containing the Vertical Platform.
2. Introduction
The axis is derrived from an experimental Meccano axis, used to produce parts from EVA during the early stages of RepRap development.
