What is a Mechanical Kit? The mechanical kit is the foundation of your CNC Machine. A mechanical kit includes all the mechanical components needed to build your CNC Machine; All the screws, nuts, wheels, plates, etc. A Mechanical Kit is a perfect choice if you plan on bringing your own CNC Controller or other Electronics. CNC Add-Ons are required to complete a CNC Machine. These include the electronic system that will control the machine, cable management, and the tool that will be mounted to the machine. About the Lead The Lead CNC Machine was originally designed by Mark Carew and the design is licensed under CC – Attribution – CC BY. This is the Maker Store kit Version 2 based on his design. Lead Version 2 is a super-strong, accurate, and easy to assemble CNC machine, made using off the shelf parts with easily customizable options such as the High Z Mod to increase the working Height. It has been designed to accurately cut foams, woods, plastics and aluminium to 0.05-0.10mm accuracy or better. Functional engineering parts, toys, signs or anything else that can be imagined, can be made on the Lead CNC Machine. The Maker Store kit has a couple of small differences from the design published by Mark Carew. Most notably are the use of Black Corner Connectors in place of Cast Brackets in order to increase rigidity and a tensioning kit to eliminate lead screw whip.
