Flatten your stock#

Use Surface to face the top of a slab.

1. Under CAM Operations, click Surface. No selection needed.
2. Pick your biggest end mill (Surface only offers end mills).
3. Set Stepover and Angle.
4. Set a shallow Depth.
5. Click Generate Toolpath.

The form shows the area it covers: the whole stock. The result is only as flat as your machine is trammed.
