 +Tip: Any mentions of "depth" or "height" for any operations are relative to the top surface of the stock that you've setup in FreeCAD. Be sure that this is set how you expect!

-  * Drag and drop the ShapeString object onto the Body object of your part, so that it becomes associated. +  * In the left panel, Model hierarchy, check that the ShapeString object is NOT inside any Parts or Bodys. It must be at the same level as your body (it should not disappear when you collape all Bodys. If not, Drag and drop the ShapeString object so that it becomes top-level. 
-  * You can now proceed to use the ShapeString to make features and toolpaths.+  * Go to the CAM workbench. 
 +  * Create a new Job, or double click an existing job to edit. (It's suggested to add to an existing to reuse your Job settings). 
 +  * In the General tab, add your shapestring object to the job: Job Edit > General > Model. 
 +  * In the popup window, make sure the shapestring object is selected. It should appear under the 2D category. 
 +  * Close the job edit task. 
 +  * You must add at least one V bit to the job's tools before adding VCarve. 
 +  * **Now to add the VCarve Operation** 
 +  * Select the Shapestring object inside the model parts within the Job!! NOT the shapestring object that is part of your Part Body. 
 +  * Create a new VCarve operation with the button in the toolbar. The shapestring should be added to the list of base geometry in the task editor window. 
 +  * Set the depth of the opreration to be excessively deep- it should not limit the tool depth. Depth at any given point is determined automatically. 
 +  * Ensure that step-down is set appropriately- TODO need to adjust..... recommend 0.3mm for steel, can be larger for Aluminum. 
 +  * Check the "Optimize movements" option. It will make the operation faster by taking shortcuts. It will not raise the tool in some cases, so this means that it's more critical for you to setup the Z axis precisely, to match the work surface. You must ensure that the top corners of the chamfers are above the surface being engraved. 
 +  * Click Apply button to preview the paths of the Operation, then OK when you're done. 
 +  * Double-check your feed rates and spindle RPMs for the tool controller that was used in the VCarve operation. You may want to create a new ToolController object to get custom feeds/speeds for this operation. 
 +  * Check the simulation of the Job by clicking the button in the toolbar. 
 +  * Click Post process. Your G-Code will be saved to the working directory where your FreeCAD file is saved! 
 +  * LOAD FILE in UCCNC, and see that it looks correct in the Main window. 
 +  * Proceed to the CNC setup section!
