If you currently have a DIY CNC or 3D printer without a shiny, red emergency button get in touch, I may be able to send you one.
Dress for the occasion
• Always eye protection and closed-capped boots.
• Wood can often create fine sawdust, so make sure you wear safety goggles, as well as a half-mask to cover your nose and mouth.
• Never wear baggy clothes, neckties, and jewellery.
• Only wear gloves when your machine is not in operation and you are handling materials.
• If your machine is loud, wear hearing protection such as soundproof buds or headphones to prevent damages to your ears.
• Don’t use a machine before making sure that all machine guards, interlocks, and other safety devices are installed and fully operational.
• Before you turn on your milling machine, make sure that your materials are centred into the router’s chuck. Then lock the guard in place before turning on the machine.
• Check all motion control switches daily.
Clean and Tidy
• Remember to completely power of the machine before deciding to clean it or perform maintenance.
• The area around the machine should be clear of oil and coolant spills. Keep the surrounding area free from obstructions.
• When finished, always clean debris from inside the machine before using it again. Avoid letting chips build up in the machine.
Looking after your machine
• Don’t ignore maintenance! Try to stop all problems before they start.
• Check your machine for damage before you power on. A damaged part could potentially ruin your machine, or worse, injure you.
• Don’t put too much weight on the table. Excessive weight increases wear, and may even cause motion failures, affect accuracy, and damage the machine.
Use your senses
• Illuminating lamps should be adjusted so that light is not directed into the operator’s eyes.
• If you are milling metal or another thermally conductive material, give the piece time to cool down before removing it from the vice.
• All CNC machines should have an emergency shutoff switch, preferably located on the control panel.
• Install a limit switch for additional safety. This will not only protect your hardware, but it will reduce the risk of fire.
• As your CNC machine will be wired to the mains power, there should be an isolator in the circuit to allow safe isolation from the power.
