Basics[edit]

  • The Universal Axis is a modular and scalable CNC axis which can be used to create cartesian CNC machines. The core of the axis is belt drive and linear motion rods where carriages are pulled on the rods. 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.
