== Powering up the machine == | |||
With very few exceptions, the same order of operations should always be maintained for safe proper operation: | |||
1. Open cutting area and remove any objects from the working bed. | |||
2. Plug in circulation pump to a 110v circuit. (currently does not power on with chiller), | |||
3. Power on 120-240 voltage converter (box on trolley with green light-up switch) | |||
--Verify that power is applied to the chiller and air pump. These are 220v appliances and need to be plugged directly into the voltage converter. | |||
4. Set up ventilation fan outdoors, leave unplugged but switch unit on. During colder temperatures only run exhaust while cutting is taking place. | |||
5. Activate power to laser cutter from switch on back of unit. | |||
6. Deactivate E-stop with a twisting motion, and power on laser with key switch on front panel. | |||
The laser is now active and ready to accept instructions from the laptop. | |||
== Using the machine == | |||
regurgitate the above here | |||
== Shutting down the machine == | |||
Following the same steps in reverse order will help ensure the machine is left in a safe mode. | |||
1. Activate E-stop to render the work-area safe. | |||
2. Clean out remnants from the cutting area. | |||
3. Turn off power from the key switch, this will turn off the work-light. | |||
4. Deactivate/put away exhaust fan | |||
5. Power down voltage converter (green switch) | |||
6. Unplug circulation pump | |||
7. Turn off power to back of unit | |||
