The Setup establishes the Work Coordinate System (WCS) for job elements. Work coordinate systems are set reference points used to establish a known datum relative to the machine coordinate system. It defines the origin and orientation of the X, Y, and Z axes as they relate to the CNC machine, and it is the reference point for all machining operations. Multiple setups can be used.

1. In the Jobs section, click the Create setup icon (shown below with the tool tip underneath):

2. This opens the Select tool library dialog:

You can import directly from the current document, or browse Other documents to select from.

3. Optionally, click the Create version icon to create a version from the active document. Click the Version graph icon to see a version graph of the active document. Click the View released items icon (if applicable) to view the released items of that document.

Exporting tool libraries

To export a tool library:

2. The tool library is exported into a new tab in the document.

3. Click the tab to access the tool library, where you can update or download the library.

1. In the Jobs section, click the Create toolpath icon on the right side of the section (shown below with the tool tip underneath):

   

2. The Toolpath settings section opens:

   

3. In the Toolpath Strategy settings section, fill in the parameters according to your preferences:

   Name - Enter a name for the toolpath.

   Type - Choose a type of toolpath from the options available:

   • Edges - Calculates toolpath based on wireframe input drive edges. It works without any machining faces.

   • Faces - Calculates toolpath based on input drive bodies.

   • Bodies -Calculates toolpath based on entire input bodies.

   • Holes - Calculates toolpath based on input holes.

   • Existing - Calculates toolpath based on existing operations.

   Pattern - Choose a pattern for the toolpath to follow from the options available:

   • 2-Axis rough - Used to remove large volumes of excess material quickly.

   • 2-Axis profile - Creates a toolpath based on the drive curves. (The drive curves will be flattened.)

   • 2-Axis chamfer - Creates a toolpath based on the drive curves and is used for chamfering and deburring operations.

   • 3-Axis profile - Creates a toolpath that follows the drive curves.

   • 5-Axis profile - Creates a toolpath that follows the drive curves where the tool axis is controlled by orientation lines along the drive curves.

   • Face - Used to machine flat areas. (The drive curves must be flat.)

   • Trochoidal - Provides sequential drive curve machining by trochoidal movements.

   • Engrave - Machines along the drive curves.

   Sub-pattern - Choose a sub-pattern for the toolpath from the options available:

   • Offset - Creates multiple cuts on multiple depths that will be offset from the selected machining surfaces.

   • Parallel - Creates parallel cuts on multiple depths.

   • Adaptive - Ensures that the cutting conditions remain almost constant. (This strategy avoids full-width cuts by constantly measuring the engagement volume of the tool with material and gradually removes material off of the remaining stock.

   1. Optionally, toggle the 2.5-Axis option which enables the machining of pockets and bosses.

   When examining toolpath information, all relevant parameters are presented for configuring the desired operation. As you adjust parameters, applicable options will filter out.

4. Fill in the remaining Toolpath Settings parameters according to your preferences:

   Offset - Specifies the amount of material to remain on the drive curves.

   Step down - Specifies the depth step.

   Step over - Defines how much the tool engages material horizontally for each pass.

   Sorting - Provides parameters for the Cutting method, Cutting directions, and Machined By.

   Heights - Set the Start height type, the Start height, the End height type, and the End height.

   Area - Set the Draft angle degree and (optionally) toggle the Close offsets option.

   Re-machining - Provides parameters for optimizing the toolpath to reduce cutting overages and only cut what is needed.

   Edge containment - Restricts the toolpath within the picked curves.

   Speeds - Define various toolpath rates and approaches. Set the speed for feed rate, plunge rate, and retract rate. Enable rapid approach, rapid retract, or adaptive feed rate.

   Posting - Defines the spindle speed and whether or not coolant is used during the machining process.

5. Click the Link section (to the right of the Toolpath section) to access the Toolpath Link settings. Fill out the parameters according to your preferences.

   Under the Clearance area dropdown section, Clearance area type designates the clearance area where the tool retracts to and approaches from for this operation.
   Under the First entry dropdown section, the Use ramps option determines if the tool utilizes the approach strategy or feeds directly into the material.
   The options in the Ramps dropdown section depend on the type of tool being used, the material being cut, and the machine rigidity.

   When enabled, Tilting defines a tilt axis.

7. Click the Collision section (to the right of the Axis section) to access the Toolpath Collision settings. Fill in the parameters according to your preferences.

   The Collision groups dropdown section has the option to modify the toolpath with parameters for retracting, trimming and re-linking, and stopping the tool along a designated axis.

8. Click the Misc section (to the right of the Collision section) to access the Toolpath miscellaneous settings. Fill in the parameters according to your preferences:

   Profile pass - Adds a path to the toolpath that follows the profile of the drive curves.

   Smoothing - Optionally choose to toggle the following options:

   • Smooth corners - Creates fillets in the sharp corners of the toolpath. (Note that the fillets will not be applied to the outer contour of the toolpath.)

   • Smooth final pass - Creates fillets in the sharp corners of the outer contour of the toolpath.

   • Remove corner pegs - Automatically modifies the step over and adds extra cuts to the corners in order to remove the uncut material.

   Filtering - Choose to filter by Regions (removes the toolpath regions that are within the threshold value) or Contours (removes the toolpath contours that are within the threshold value). Choose a Filter type and enter a Filter threshold value.

   Quality - Enter a cut tolerance to specify the accuracy of the toolpath. It is the chordal deviation of the toolpath against the features to be machined.

9. Click OK to accept. The toolpath is added to the Jobs list.

Click the three dot menu to the right of a toolpath to edit, duplicate, suppress, or delete that toolpath.

Under the Jobs section, click the Preview operation icon to the right of an operation to view the Back plot, Verify, or Simulate. (To verify or simulate all operations at once, click the Preview operation to the right of a setup in the Jobs section.)

This activates the preview operation options in the bottom of the graphics area:

Each operation produces a different result:

Back plot - Moves the tool along the toolpath.

Use the top sliding bar to set the speed of the automation (the left side being the slowest, and the right side being the fastest).

Use the Step back, Run, Step next, and Cancel options as preferred.

The bottom sliding bar indicates the progress of the back plot animation.

Verify - Moves the tool along the toolpath while removing material, allowing you to find out more about gouges and excesses, and refine the in-process material (stock).

The sliding bar sets the speed of the animation (the left side being the slowest, and the right side being the fastest).

Use the Step back, Run, Step next, Go to end, Reset, and Cancel options as preferred.

Simulate - Previews the operation.

The sliding bar sets the speed of the animation (the left side being the slowest, and the right side being the fastest).

Use the Step back, Run, Step next, Go to end, Reset, and Cancel options as preferred.

The bottom row of buttons toggles the visual on and off for the tool, toolpath, workpiece, stock, and machine housing.

You also have the option to toggle pause on collision.
