=== Introduction ===
=== Introduction ===
CNC plasma cutting is a process that uses a high-temperature jet of ionized gas to cut through electrically conductive materials, such as steel or aluminum. This tutorial will guide you through generating drawings and toolpaths in Fusion360, and then post-processing and cutting those designs on a ShopSabre CNC plasma cutter.
CNC plasma cutting is a widely used method for cutting metal sheets using a high-temperature plasma jet. This guide provides a comprehensive overview of how to generate 2D drawings, create toolpaths using Autodesk Fusion 360, and post-process these designs for cutting on a ShopSabre CNC plasma cutter.

=== Step 1: Generating Drawings in Fusion360 ===
1. **Open Fusion360:**
# '''Open Fusion360:'''
   - Launch the software on your computer.
   - Launch the Fusion360 application and create a new design by selecting "File" > "New Design".
  - Open a new project or your existing project.


2. **Create a Sketch:**
# '''Create a New Sketch:'''
   - Select the "Create Sketch" option from the toolbar.
   - Click on "Create Sketch" in the toolbar.
   - Choose the plane you want to sketch on (e.g., XY Plane).
   - Choose the plane (e.g., XY Plane) where you want to create your design.
  - Use the sketch tools (line, circle, rectangle, etc.) to draw your design. Ensure your design is clean and properly constrained.


3. **Finish Sketch:**
# '''Design Your Part:'''
   - Once your sketch is complete and dimensioned, click on "Finish Sketch" in the toolbar.
  - Use the sketching tools available (Line, Circle, Rectangle, Arc, etc.) to create your desired shapes.
   - Ensure that your sketch is fully constrained by applying dimensions and geometric constraints for precision.


4. **Extrude the Sketch:**
# '''Finish the Sketch:'''
  - Select the sketch geometry you wish to extrude.
   - Click "Finish Sketch" in the toolbar once your design is complete.
   - Click on the "Create" dropdown menu and select "Extrude."
  - Set the parameters for the extrusion (distance, direction, etc.). Although the primary goal is cutting a 2D plane, extrusion helps visualize thickness.

2. **Setup:**
# '''Set Up the Job:'''
   - Click on "Setup" in the toolbar to create a new setup.
   - Click on "Setup", then "New Setup".
   - Define the operation type as "Cutting."
   - Choose the operation type as "Cutting", and configure the Work Coordinate System (WCS) according to your ShopSabre CNC machine setup.
  - Set the work coordinate system (WCS). Usually, X and Y should align with your plasma table, and Z should be set to the top of the material.
  - Select your stock box point as the point you want the cutting to start from.


3. **2D Profile Toolpath:**
# '''Define Stock Material:'''
  - In the toolbar, choose "2D Profile" under the "Cutting" dropdown.
   - Specify the dimensions of the stock material you will be cutting. Create a bounding box that represents the material dimensions.
   - Select the contour or edges of your design to be cut.
  - Configure the toolpath parameters:
    - **Cutting feedrate and speed** according to your plasma cutter’s recommendations.
    - **Pierce height and cut height** to be set accurately.
    - Ensure the lead-in and lead-out settings are appropriate to avoid material warping or improper cuts.


4. **Generate Toolpath:**
# '''Create Toolpath:'''
   - Click "OK" to generate the toolpath.
   - Select "2D" from the toolpath options and choose "2D Profile".
   - Use the simulation feature to ensure the toolpath is accurate and cuts according to the design specifications.
  - Click on the edges of the sketch that you want to cut.
 
# '''Set Toolpath Parameters:'''
  - Choose a suitable cutting tool for plasma cutting, ensuring that the settings match your plasma cutter's specifications.
  - Define parameters such as '''Cutting Speed''', '''Feed Rate''', '''Pierce Height''' (the height at which the torch pierces the material), and '''Cut Height'''.
  - Adjust '''Lead-in and Lead-out''' settings to enhance cut quality and minimize dross.
 
# '''Simulate the Toolpath:'''
   - Use the simulation feature to preview the cutting process, ensuring there are no potential collisions or errors.

# '''Select the Post Processor:'''
   - In the toolbar, select "Post Process."
   - In the toolbar, click on "Post Process".
   - Choose the post-processor configuration file for ShopSabre (it will typically have a .cps extension). If not available, download it from the Autodesk post-processor library or ShopSabre’s website.
   - From the drop-down menu, select the appropriate post-processor for the ShopSabre CNC plasma cutter (typically a .cps file).
   - Configure any additional settings required by the ShopSabre machine.
 
# '''Configure Post Processing Settings:'''
  - Adjust any additional settings in the post-processor to align with your ShopSabre requirements.
 
# '''Generate G-Code:'''
  - Click "Post" to create the G-code file.
   - Save the G-code file to a location accessible by your ShopSabre CNC cutter, such as a USB drive or a designated project folder.


2. **Generate G-Code:**
=== Step 4: Preparing and Cutting on the ShopSabre CNC Plasma Cutter ===
   - Click "Post" to generate the G-code file.
# '''Machine Setup:'''
   - Save the G-code file to a USB drive or the appropriate directory that your ShopSabre CNC plasma cutter reads from.
   - Secure the material to the CNC plasma cutter bed, ensuring it is flat and stable.
   - Check that the plasma cutter settings (gas type, pressure, and cutting height) are appropriate for the material you are using.


=== Step 4: Cutting with ShopSabre CNC Plasma Cutter ===
# '''Load G-Code:'''
1. **Set Up the Machine:**
   - Access the ShopSabre CNC controller interface and load the G-code file generated from Fusion 360.
   - Place the material securely on the plasma cutting bed.
   - Ensure the file loads without errors.
   - Ensure the plasma cutter is properly configured with the correct cutting parameters (nozzle size, gas settings, work height, etc.).


2. **Load G-Code:**
# '''Perform a Dry Run:'''
   - On the ShopSabre controller, load the G-code file generated in Fusion360.
   - If possible, execute a dry run of the toolpath without activating the plasma torch. This allows you to confirm the path is correct and free of obstructions.
  - Confirm the file loads without errors.


3. **Initialize the Cut:**
# '''Initiate the Cutting Process:'''
   - Perform a dry run (if possible) to ensure the toolpath is correct without engaging the plasma torch.
   - Once the dry run is confirmed, start the cutting program. Monitor the process closely for any unexpected behavior.
  - Begin the cut, monitoring the initial stages to ensure everything is functioning correctly.


4. **Post-Cutting:**
# '''Post-Cutting Procedures:'''
   - Allow the cut piece to cool down properly.
   - After cutting is complete, allow the material to cool before handling.
   - Remove the finished piece and check for precision and quality.
   - Inspect the cut parts for accuracy and quality, ensuring they meet the desired specifications.
