| + | ======Introduction===== | ||
| + | |||
| + | Our CNC Router is a Shapeoko 3 XL. | ||
| + | |||
| + | The router has a usable bed size of 800mm X 350mm. | ||
| + | |||
| + | We have 1/4" and 1/8" collets for the router, and a small collection of bits for basic operations. For anything more complex (or to guarantee a sharp bit) you should use your own router bits. | ||
| + | |||
| + | The router is driven using Carbide Motion, which is loaded on the Raspberry Pi the wooden box beside it. | ||
| + | |||
| + | The router is protected by an online induction. To get inducted, read this page carefully, then take the quiz on the membership system. | ||
| + | |||
| + | This wiki page will explain the basics of how to safely set up and run a simple job on the router. It will not teach you how to design things for the router, prepare files for cutting. | ||
| + | |||
| + | To learn more about the router, including how to design and prepare files for it, check out these videos by the manufacturer: | ||
| + | |||

| + | * [[https:// | ||
| + | |||
| + | For first time CNC users, we recommend using the free version of Carbide Create to design and prepare your files, as this software comes pre-programmed with the parameters of our machine and our communial bits. | ||

| - | **CAM** – // | + | ====== Usage Insturctions ====== |
| - | Software that converts your CAD design into movement instructions for the CNC. | + | |
| - | * **We use:** Carbide Motion (pre-installed on the workshop Raspberry Pi) | + | |
| - | * **Why it matters:** This is the “translator” between your design and the machine. | + | |
| - | **G-code** | + | ====1. Pre-Useage Checks==== |
| - | The text-based “language” CNC machines read. Generated automatically by CAD/CAM software. You don’t need to write it manually. | + | |
| - | ===== Machine Movement ===== | + | Before you use the CNC Router, it's important to open the cabinet doors and check the following: |
| - | **Axes** | + | |
| - | * **X:** Left ↔ Right | + | * There is not a thick dust build up on top of the big silver gantries. |
| - | * **Y:** Front ↔ Back | + | * That there is nothing inside |
| - | * **Z:** Up ↔ Down | + | |
| - | //Tip: Y has the “Y rails” and Z is the vertical axis — that leaves X as side-to-side.// | + | |
| - | **Home Position** – The fixed point the machine returns | + | You also need to check that: |
| - | **Work Zero** – Your chosen starting point for a specific job (usually a corner or centre of the stock). | + | |
| - | ===== Design Files ===== | + | * The fire extinguisher is present in the woodshop. |
| + | * The dust collector bag is not full. | ||
| - | **Vector Graphics**\\ | + | If you see anything wrong with the condition |
| - | Drawings made of lines and points (e.g., SVG files). Ideal for CNC because | + | |
| - | **Toolpaths**\\ | + | ====2. Starting the Machine and Software==== |
| - | The routes your cutter will follow. Defined in CAD, turned into G-code in CAM. | + | |
| - | ===== Materials & Workholding ===== | + | * Log into the machine with your card/fob (once you've passed the induction). The enclosure lights should turn on when you log in. |
| + | * If the Raspberry Pi is not already running, press the silver power button to boot it up. Note that the screen may not immediately respond when you press the button. | ||
| + | * If the emergency stop button has been pressed, rotate it clockwise to reset it. | ||
| - | **Stock** – The material you’re cutting.\\ | + | Once the Raspberry Pi has booted: |
| - | **Spoilboard** – A sacrificial board under the stock to protect the machine.\\ | + | |
| - | **Workholding** – Clamps or other methods to secure your stock so it doesn’t move. | + | |
| - | ===== Cutting Parameters ===== | + | * Start the " |
| + | * In Carbide Motion, press the " | ||
| + | * Press the " | ||
| - | **Feed Rate** – How fast the cutter moves through the material (X/Y).\\ | + | The router will now move to the rear rightmost point, and will then move to the front right. |
| - | **Plunge Rate** – How fast the cutter moves down into the material (Z).\\ | + | |
| - | **Spindle Speed** – How fast the bit spins (RPM), adjusted on the router dial.\\ | + | |
| - | //Why it matters:// These three settings determine cut quality and safety. Carbide Create has safe starting values for common materials. | + | {{:equipment: |
| - | ===== Tools & Cutters ===== | + | ====3. Clamping Down your Stock==== |
| - | **End Mill / Bit** – The cutting tool. | ||
| - | * **Flat End Mill** – Flat tip, general-purpose cutting. | ||
| - | * **Ball End Mill** – Rounded tip, for 3D contours and smooth finishes. | ||
| - | * **V-Cutter** – Angled tip, ideal for engraving and sign work. | ||
| - | * **Fly Cutter** – Large flat cutter for surfacing spoilboards or material tops. | ||
| - | **Flutes** – The cutting edges on a bit. More flutes = smoother cut, fewer flutes = faster removal. | + | NOTE: All items for the CNC including probe pins, router bits, collets spanners and allen key can be found in the small draw under the Raspberry Pi and returned here after use. |
| - | **Upcut / Downcut** – Direction of flute spiral: | + | *****Before you clamp down your stock, move the router out of your way: |
| - | | + | |
| - | * **Downcut:** Pushes chips down (better surface finish, but can trap chips). | + | |
| - | **Shank size** – the size of the diameter | + | |
| - | * **1/8** - 1/8 inch (3.175mm). | + | * From the Jog Screen, use the buttons on the screen or the USB pendant to move the router out of your way. |
| - | * **1/4** - 1/4 inch (6.35mm). | + | |
| - | ---- | + | * Place your stock on the spoilboard. Use the small "stop blocks" |
| + | * Use the Crush-It clamps on the opposite side of your stock to hold it securely. To do this. first loosen (but don't remove) the small screws on the front of the clamps, position the clamps tightly against your stock, bolt the clamps to the spill board, then tighten the front screw to push the clamp face firmly against the stock. | ||
| + | * Double-check that your stock is firmly attached to the spillboard by trying to move it. If there is any movement, you should re-clamp it. | ||
| - | ===== Machining Types ===== | + | Tip: The stop blocks have smooth and serated sides, and the Crush-It clamps have replacable smooth and serrated jaws. The serrated surfaces give better grip but can leave marks on some stock. |
| - | **2D Machining** – Cutting shapes at a constant depth.\\ | + | Tip: Make sure the clamps don't block your toolpath! |
| - | **2.5D Machining** – Multiple depths, but cutting one flat layer at a time (e.g., pockets + cutouts).\\ | + | |
| - | **3D Machining** – Machine moves in X, Y, and Z simultaneously to create complex curves.\\ | + | |
| - | ===== Safety ===== | + | Tip: Use bolts of the correct length to fix the clamps to the spillboard. If the bolts are too long they will bottom out in the threaded holes. |
| - | **Emergency Stop (E-stop)** – Red button to immediately stop the machine.\\ | + | NOTE: Don't over tighten |
| - | **PPE** – Safety glasses, hearing protection, dust mask.\\ | + | |
| - | **Dust Collection** – Removes chips and dust from the work area. | + | |
