| - | ====== | + | Our CNC Router is a Shapeoko 3 XL. |
| - | Most definitions here are adapted from Carbide3D’s video series, with small changes for our machine and accessories.\\ | + | The router has a usable bed size of 800mm X 350mm. |
| - | **Tip:** These are the basics you’ll need for your induction quiz. Links to the original videos are at the bottom if you want to go deeper. | + | |
| - | ==== Core Concepts ==== | + | 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. |
| - | **CNC** – //Computer Numerical Control// | + | The router is driven using Carbide Motion, which is loaded on the Raspberry Pi the wooden box beside it. |
| - | A computer-controlled machine that moves a cutting tool with high precision. Our laser cutter, 3D printers, and vinyl cutter are also CNC machines. | + | |
| - | **CAD** – // | + | The router is protected by an online induction. To get inducted, read this page carefully, then take the quiz on the membership system. |
| - | Software used to design your part. You draw shapes, add features, and prepare them for cutting. | + | |

| - | **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 ==== | + | You can work with the following materials on the CNC router: |
| + | * Hard wood | ||
| + | * Soft wood | ||
| + | * MDF | ||
| + | * Plywood | ||
| + | * Acrylic | ||
| + | * Delryn | ||
| - | **Feed Rate** – How fast the cutter moves through the material (X/Y).\\ | + | You must NOT work with these materials: |

| - | //Why it matters:// These three settings determine cut quality and safety. Carbide Create has safe starting values for common materials. | + | ====== Usage Insturctions ====== |
| - | ==== Tools & Cutters | + | ====1. Pre-Useage Checks==== |
| - | **End Mill / Bit** – The cutting tool. | + | Before you use the CNC Router, it's important to open the cabinet doors and check the following: |
| - | * **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 | + | |
| - | * **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. | + | |
| + | | ||
| + | * That there is nothing inside the enclosure that could interfere or jam the movement of the router. | ||
| - | **Upcut / Downcut** – Direction of flute spiral: | + | You also need to check that: |
| - | * **Upcut:** Pulls chips up and away (better chip removal, but can lift stock). | + | |
| - | * **Downcut: | + | |
| - | **Shank size** – the size of the diameter of the solid part of the bit, two sizes are currently supported by our router: | + | |
| - | * **1/8** - 1/8 inch (3.175mm). | + | * The dust collector bag is not full. |
| - | * **1/4** - 1/4 inch (6.35mm). | + | |
| - | ---- | + | If you see anything wrong with the condition of the machine, don't use it and let the committee know on the forum. |
| - | ==== Machining Types ==== | + | ====2. Starting the Machine and Software==== |
| - | **2D Machining** – Cutting shapes at a constant depth.\\ | + | |
| - | **2.5D Machining** – Multiple depths, but cutting one flat layer at a time (e.g., pockets + cutouts).\\ | + | * 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. |
| - | **3D Machining** – Machine moves in X, Y, and Z simultaneously | + | * If the emergency stop button has been pressed, rotate it clockwise |
| - | ==== Safety ==== | + | Once the Raspberry Pi has booted: |
| - | **Emergency Stop (E-stop)** – Red button | + | |
| - | **PPE** – Safety glasses, hearing protection, dust mask.\\ | + | * In Carbide Motion, press the " |

| - | ==== Powering up the machine ==== | + | 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. |
| - | | + | *****Before you clamp down your stock, move the router out of your way: |
| - | | + | |
| - | | + | |
| - | | + | |
| - | * Check that there is no thick dust build up on top of the big silver gantry' | + | |
| - | * Check that there is nothing left loose inside the enclosure that could jam the movement | + | |
| - | ==== Starting | + | * Press the " |
| + | * From the Jog Screen, use the buttons on the screen or the USB pendant to move the router out of your way. | ||
| - | * Start the Carbide Motion software by pressing the raspberry button in the top left -> Office -> Carbide Motion\\ | + | * Place your stock on the spoilboard. Use the small "stop blocks" |
| - | * Press the "Connect to cutter" | + | * Use the Crush-It clamps |
| - | * Press on " | + | * 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. |
| - | ==== Installing probe pin ==== | + | 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. |
| - | First install the correct collet for the size you’ll be using: | + | Tip: Make sure the clamps don't block your toolpath! |
| - | * Use a 17 mm spanner to loosen the collet nut on the bottom of the router. | + | |
| - | * Press and hold the yellow spindle lock button (on the lower right of the router) to stop the shaft from spinning. | + | |
| - | * Remove the collet nut and old collet together. | + | |
| - | * Fit the new collet and collet nut, using the same process in reverse. | + | |
| - | Then choose | + | 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. |
| - | Use the measuring guide to check the pin isn’t sticking out too far. Once correct, hold the spindle lock and tighten the nut with the 17 mm spanner. | + | ====4. Probing your Stock Location==== |
| - | ==== Clamping down stock ==== | + | We have a BitZero probe kit, which we use to accurately locate corner of your stock is and how tall it is. This is known as setting the "Work Zero". The kit consists of a probe pin, a probe plate, and a magnetic earth connection. To use the BitZero: |
| - | In Carbide Motion press the Jog button | + | * Remove |
| + | * Install a probe pin into the router collet (using the instructions for installing router bits and probe pins at the bottom of this page). | ||
| + | * Place the probe plate on your stock so so that is tight to the front left corner. | ||
| + | * From the Jog Screen, use the buttons on the screen or the USB pendant to position | ||
| + | * Attach the magnetic earth to the router collet. | ||
| + | * From the Jog Screen, press Probe. A pop-up window will open. | ||
| + | * Press " | ||
| - | Place your stock on the spoilboard so it’s aligned | + | The router will move slowly to identify |
| - | Use the small stop blocks on one side to position the stock — each block has two smooth sides and two with small serrations. The serrated sides give better grip but can leave small marks on the stock. | + | When it has finished doing this, a pop-up window will ask you to remove |
| - | Use the Crush-It clamps on the opposite side to hold the stock securely. Each clamp has replaceable front jaws (smooth or serrated) for different materials. Loosen, but don’t remove, the front screw on the clamp. Position the clamp tight against the stock and bolt it down. Then tighten the front screw to push the clamp face firmly against | + | * Remove |
| + | * Press the Ok button. | ||
