OX CNC TinyG Guide
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.
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.
Important settings to get right: (Note these settings are all in MM)
- $1tr=60 - Gt3 belt 40 tooth pulley
- $2tr=60 - Gt3 belt 40 tooth pulley
- $3tr=60 - Gt3 belt 40 tooth pulley
- $4tr=8 - The acme lead screw
Please make sure you apply these settings BEFORE you hookup the spindle PWM to your TinyG and apply power. If not your spindle could start spinning on power up.
