Make a backup of the configuration and file installation, we recommend creating a backup of the current installation by right-clicking in the current installation folder and zipping it. 

Before configuring the THC make sure you have wired and configured and tested the initial probing. This could be done with the Plasma Touch Sensor or a Floating Head
