Overview

The OX is an open source CNC machine that is sold by smw3d. This page is a work in progress please feel free to update it as needed.

Settings Overview

Typically the configuration is as follows:

  • Motor 1 - X axis
  • Motor 2 - Y axis
  • Motor 3 - Y axis
  • Motor 4 - Z axis

The OX's spindle can also be controlled via TinyG/gcode or manually with a potentiometer (manual nob). If you plan on using TinyG's PWM feature to control your OX please see the Spindle Settings.

This is a dual Y setup.
