• Perform a “machine origin return” (homing) to avoid collisions.
• Manually jog each axis to check smooth travel across its full stroke.

Step 2. Workpiece Setup and Clamping

• Place a sacrificial board (spoilboard) on the worktable to protect the surface.
• Position the workpiece securely on top of the board.
• Use clamps, T-slot fixtures, or vacuum table (if available) to fix the material.
• Double-check stability—loose workpieces may cause vibration or tool breakage.
• Set the workpiece origin:
Move the spindle close to the edge of the workpiece.
Slowly lower the tool until it just touches the surface.
Zero the coordinates (X, Y, Z) in the control software.

Step 3. Tool Installation and Changing

• Ensure spindle power is off before changing tools.
• Move spindle to a convenient position and place a soft pad underneath in case the tool drops.
• Use the correct wrenches to loosen the collet nut and remove the current tool.
• Clean the collet and chuck to remove dust or chips.
• Insert the new router bit (not fully to the end, leave ~2mm gap) and hand-tighten the nut.
• Use two wrenches to firmly tighten, but avoid excessive force.
• Reset the Z-axis origin after tool change.

Step 4. CNC Programming and Cutting

• Confirm the following before machining:
Tool is firmly clamped.
Workpiece is securely fixed.
Correct NC program (G-code) is loaded.
Workpiece origin is properly set.
• Start the program at a reduced feed rate (30–50%) for safety.
• Monitor the operation closely; once stable, increase feed rate to normal.
• Always supervise the cutting process—never leave the machine unattended.

Step 5. Power Off and Shutdown

• Return the machine to its home position.
• Remove the tool if necessary, leaving the collet nut on the spindle.
• Switch off the machine power.
• Shut down the computer and software.

With these steps, even beginners can safely operate a CNC router. Regular maintenance, correct tool selection, and proper clamping are the keys to smooth machining and long equipment life.
