Carve a 3D model (STL)#

1. Click Import File and pick the .stl.

2. A rectangle appears. Move and resize it to place the carve. Resize evenly (corner handle) or the depth will be distorted.

3. Check the model in 3D View.

4. Under CAM Operations, click 3D Profile.

5. Set:

   Field	Value
   Model	your STL (listed under STL)
   Roughing Tool	A bigger ball nose, a bull nose or an end mill (optional)
   Finishing Tool	Ball nose, bull nose or taper
   Finishing Stepover (XY)	10–20 % for a good finish
   Finishing Strategy	Raster (or Waterline)
   Max Depth	How deep it may go

6. Click Generate Toolpath.

7. Simulate in 3D View before cutting.

Finishing (green) at 45°; roughing (red) defaults to 90° from it, at 135°.

The top of the model sits at the top of the stock. Undercuts can't be carved.
