Injury due to the workpiece coming loose during routing. An emergency stop button is located next to the CNC router. There are various options for clamping the workpiece to the CNC bed. These should be used in excess and if any movement is observed, the emergency stop button should be pressed. 5/3 The e-stop should be tested before cutting actually begins. The user might not be aware of the Superbox CNC Router advice. Update wiki page to include this.
Ensure a QR code for the wiki page is prominently displayed by the machine. 		3
