This section describes how to create the first machine-relief toolpath, which applies to the entire block of material. Use this toolpath to remove the bulk of the material using a 3 mm ball-nosed tool.

To create the first toolpath:

1. In the Project Tree, select the Toolpaths item. The Toolpaths panel is displayed.
2. Click the Create Machine Relief Toolpath  button. The Machine Relief panel is displayed.
3. In the Area to Machine area, select Whole relief in the list.
4. Specify the tool for machining the relief:
   
   
   1. In the Finishing Options area, click the Click to Select control bar. The Tool Database dialog is displayed.
   2. In the Tools & Groups pane, select Tools & Groups > Metric Tools > Wood or Plastic > 3D Finishing > Ball Nose 3 mm. The tool's details are displayed in the Tool / Group Description pane.
   3. Click Select. The dialog closes and the tool's settings are displayed in the panel.
5. Specify the settings for the toolpath:
   
   
   1. In the Tool clearance strategy list, select Raster (Classic) to machine in multiple passes, back and forth along the X axis.
   2. Enter an Angle of 0 to specify the angle between the tool and the X axis.
   3. Enter a Tolerance of 0.01 to specify how closely the tool follows the relief.
   4. Enter an Allowance of 0.1 to specify the distance between the tool and the relief.
   5. Click the Multiple Z passes control bar to display its settings.
   6. Select the Do multiple Z passes check box to enable the tool to remove the material in a series of passes. For each pass, the tool moves downwards by the Stepdown value, which is 3 mm.
   7. Enter a Start Z value of -3 to specify the depth from the material's surface at which the tool machines the first pass.
   8. Enter a Finish Z value of -45 to specify the depth from the material's surface at which the tool machines the last pass.
   9. In the Options area, click the Safe Z and Home control bar to display its settings.
   10. Enter a Safe Z value of 10 to specify the height above the material's surface at which the tool can make rapid moves between toolpath segments.
   11. Enter a Home X value of 0, Home Y value of 0, and Home Z value of 10 to specify the tool's start and end position.
6. Specify the dimensions of the block of material from which the relief is to be machined:
   
   
   1. In the Options area, click the Click to Define Material control bar. The Material Setup dialog is displayed.
   2. Enter a Material Thickness of 45.
   3. Click and drag the Model Position In Material slider downwards until 5.747 is displayed in the Top Offset box and 0.0 is displayed in the Bottom Offset box.
   4. Click OK. The dialog closes and a transparent block is shown around the lizard relief in the 3D view.
7. Enter a Name of Machine Relief 1 for the toolpath.
8. Click Calculate Now.

   Carveco calculates the toolpath and adds a Machine Relief 1 item under the Toolpaths item in the Project Tree:

   
   

   The toolpath (red), rapid moves (blue) and plunge moves (cyan) are displayed:

   
   

9. In the Project Tree, click the lightbulb  icon next to the Machine Relief 1 toolpath to hide the toolpath. The icon changes to .
