HintLightbulb.png Hint: The Universal Axis is a modular and scalable CNC axis which can be used to create cartesian CNC machines. The core of it is belt drive and linear motion rods where carriages are pulled on a rod. The system is scalable to any size and number of axes, including rotary axes. THe system uses a combination of 3D printed parts, metal plates, and belt-driven shafts. Applications include 3D printers, CNC torch tables, heavy duty CNC machines, and many other production machines.

Intro[edit]

The following is a 5/16" or 8 mm version of the universal CNC axis described at http://opensourceecology.org/3d-printer-construction-set-workshop/

Larger axes will also be built, up to 2" for heavy duty CNC machining, with plastic parts sandwiched between metal plate as a plastic/metal composite structure. See calculations for beam deflection at Heavy_Duty_CNC_Construction_Set.
