Open your PowerMill project and generate your 4-axis toolpaths.
Finding a reliable download for a 4-axis post processor depends on your machine’s controller (Fanuc, Haas, Heidenhain, Siemens, etc.). Here are the primary sources:
In the NC Preferences dialog box, locate the field.

If you can tell me the (e.g., Fanuc 0i, Mach3) and the 4th axis setup (e.g., A-axis parallel to X), I can provide more specific advice on where to find the best post processor for your setup.
If you are looking for a baseline file to customize, verified user communities can be helpful:

Finding the right is a critical step in bridging the gap between your CAM toolpaths and your CNC machine's physical capabilities. Unlike standard 3-axis versions, 4-axis post processors are highly dependent on your specific machine kinematics—such as whether the rotary axis moves around the X-axis (A-axis) or Y-axis (B-axis).
