INTRO

Below you will find parts and tools, which will help you to print and assemble CNC Machine. All axes are with NEMA 23 motors and ACME 8mm lead screws for better accuracy at the expense of speed (compared to belt driven axes). If you noticed mistakes, weaknesses in design, have questions or suggestions, know original part manufacturers or better alternatives (available in EU and US), please write or send link to info@jocys.com • Project page: Jocys.com/CNC

Parts were printed from PETG with Prusa3D i3 MK3 Printer . If your printer is not precise enough, printed parts may not fit into each other and may not look good. Spaces between some parts are 0.1mm only.

Electronics by TinkerForge (DE) supports various programming languages . I am using this CNC Machine with my own software for light tasks. My own software will not be available for download. Depending on what you want to do, you may need to use electronics by other manufacturer. TinkerForge allows you to write your own software, but you may need something, that exists already, and TinkerForge doesn't support that.

I hope, you will find this project or parts of it useful. If you made your own updates or changes, related to this project, please send me a link. I will add this link on this page.
