Adding a tool to the turret is a simple matter. Select the Add Command button to open a list of the tools that are in the currently loaded Tool Inventory, which appears on the right side of the Turret List window. When a tool is selected (such as this SQ 0.433 tool) all stations in the turret that are the correct size for that tool will be hi-lited in blue, as shown here. Drag and drop the tool into any one of those stations.
To access the Turret List window shown here, select the System Setting tab and then click the Turret Info icon.
