*Laptop: The laptop is used to upload the design that need to be cut to the laser. It is also used to configure all the necessary setting of the laser. Note that the operating system running on the laptop is Windows 7.

*Air Filter: The filter should always be attached while performing a cut, the laser cutter is not to be used without the filter, this ensures that the air in the room is safe for users and limits potentially hazardous debris.

*Air Compressor (compressed air): A steady flow of air to blow smoke and cutting residue away from the beam path and optics of a laser cutter. It's simple, but critical; without it, smoke can obscure and reflect the laser beam, foul lenses and mirrors, and severely degrade cut quality.

One way for the user to interact with the laser is by using the control panel. The list below describes the properties of each button found in the laser cutter control panel.

Note, the focusing tool for the Epilog Zing is different from the other laser cutters, it is attached inside the machine itself and can move back and forth, hence showing the distance between it and the material to be cut.

===Prepare your file and select your material===

Before you are going to start laser cutting, you need to get some prep work out of the way. First you need to create or select your file. If you are rastering an image, you can select or create an image in any program or use an existing picture. If you are rastering an image, you can select or create an image in any program or use an existing picture.

If you want to add vector cuts, you need to use a program that has the ability to create vectors. We use a free program called Inkscape. A guide on how to use the program can be [[Digital technologies/Laser cutting/Vector graphics- Beginner|found here]]. Unfortunately, you can’t print directly from Inkscape, you need to simply save your file as .pdf.

===Turn on the laser cutter ===

There are three items to turn on:

−

* '''Laser cutter:''' Switch on left hand side at the back. When you turn on the laser cutter, let the head move around freely. Refrain from touching any other buttons until it has finished this process.

The laser cutter needs to be adapted to the material and image you are going to cut. This is done by changing the height and the laser’s home. The height affects the laser’s focus, and the home is related to the center engraving. More information about this can be found on the laser settings page.

−

* '''Setting home:''' This is setting the origin for the laser. If you do not have center engraving, select. This will be the top left-hand corner of the piece. For more information, see the laser setting page.

*# Using the up and down arrows, lower or raise the bed until the manual focus guide is resting on the material without being lifted off the base. Try to swing the focusing tool back and forth. If the tool doesn't move freely after its first swing, that is, it returns to its original position, the laser has been correctly focused.

#Make sure that the picture is set to Actual size. If it is set to fit the vector lines will most likely not work.

# Select orientation, either auto, portrait, or landscape. Most of the time, this will be set to auto portrait/landscape. This means that the laser will look at the size of the image you are attempting to cut and the size that you have added in the properties page. It will attempt to place the image in the way that it will fit best. If you want your image in a specific direction, select either portrait or landscape.

When all settings are chosen, click print. If you look over to the laser cutter the name of the file should appear on the control panel. Wait until the data light is no longer flashing.

If at any point you are unsure, pause your cut and find the Makerspace Coordinator on duty. You can pause your cut by pressing the red button, Stop, it will always finish the line that is cutting before it ends. If it needs to be stopped for safety purposes and it is not stopping with the Red Button, use the On/Off switch on the left side of the laser. Leave the lid closed. To resume, press the green button, Go.
