From the project

Second version of Hacklab's custom built CNC machine

Sergei 2 CNC machine project ============================

This repository contains design files for Hacklab Jyväskylä's CNC machine project. The machine is built out of existing linear assemblies that have been donated to us, and as such it is not readily reproducible. But some of the modules may be useful and in any case this repository contains information for future maintenance of the machine.
