Start EdgeCAM in the ZX turn environment or open your pre-defined seed file. See Selecting the Environment.
Construct geometry in EdgeCAM to define your part or insert a pre-drawn design model (i.e. from a 3rd party CAD system). This can be a wire frame or solid model.

Inserting the pre-drawn model
Orientate the component geometry onto the spindle centreline.
For wire frame, this is done using the Edit, Transform (Edit menu) commands. See About Editing Geometry.
For solids, use the Align Body for Turning (Solids menu) command. See Aligning the Body for Turning.

Position the component away from the main spindle by the desired amount using the Transform, Translate (Edit menu) command.

Positioning component
If you are working with solids, perform a Feature Find (Solids menu) as required on the Turn CPL.

Feature Finding
Define your main spindle using the Stock/Fixture (Geometry menu) command, selecting the Turn Envelopes and Lower Turret check boxes. See Creating Stock or Fixtures.

Automatic cylindrical stock with extensions.
Create the appropriate CPLs on any milling faces you wish to machine .If you are working with solids, perform a Feature Find (Solids menu) command as required on these faces.
Create the main and sub-spindle fixtures using the Stock/Fixture (Geometry menu) command. Choose the Turn Billet option (for 2d profiles) or digitise (for solid models). See Creating Stock or Fixtures.
Go to Manufacture mode and specify the initial setup parameters. The lathe setup is used in preparation for sub-spindle machining. The purpose is to transfer the component geometry to the sub-spindle and create the component datum for the main and sub-spindle. See Defining a Machining Sequence.
