== How to Laser cut? ==
The laser cutting process with the Epilog Zing is as follows:
# Prepare your file and select your material
# Move your file to the laser cutter computer (you may use one of the many USB keys owned by the Makerspace)
# Turn on laser cutter setup
# Prepare laser cutter
# Click print and select print settings
# Start the cut
# Turn off laser cutter setup
# Clean up
=== 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.
=== Move file to the laser cutter laptop ===
Once you have saved your file as a .pdf, move it to a USB drive and bring it over to the laser cutter laptop. Open your file on the laptop.
=== 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.
* '''Air filter:''' Power button at bottom front.
* '''Air compressor:''' Switch Located on top left hand side
=== Prepare the laser cutter ===
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.
*# Make sure the laser cutter is on.
*# Press the pointer button. You should see a red dot under the laser head. That is the current location of the laser.
*# Press X/Y off. You should be able to freely move the laser cutter head.
*# Move the laser head so that the red dot is at the desired origin.
*# Press set home. You should no longer be able to move the laser head and you home is set.
* '''Focusing laser:''' We '''do not''' use the automatic focus function on the laser (Please, '''NEVER''' check the box for Auto-Focus it will break the laser), therefore you need to manually focus the laser before your cut.
*# Make sure the laser is on.
*# Place the material on the laser bed. You want to make sure that the area you are cutting is parallel to laser bed and the track on which the laser head moves. If there is a variation in height, you will see a variation in properties of the rastering and vectoring done by the laser
*# Use the focusing tool present inside the laser cutter.
*# Press the Focus button on the laser cutter control panel. The laser head will move over slightly, make sure that the material is still under the manual focus.
*# 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.
=== Click print and select settings ===
On the computer, click print. The print setup window will appear.
# Change the printer to the laser cutter you are going to be using.
# Click on properties. This will bring up a page on the laser cutter settings. Consult the laser cutter manual for the proper speed and vector settings. More information on settings can be found on the Laser Settings page. When you are done selecting all your settings, click ok. This will take you back to the print page.
# 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.
=== Start cut[edit | edit source] ===
# Make sure that the glass cover is down and that you have prepare the laser. Check that your job is set on displayed on the laser cutter.
# Press the green go.
# While the laser cutter is cutting, do not leave the laser cutter unattended. If small flames appear, '''do not panic.''' As long as you piece is not actively burning, you are ok. 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 stop button, 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 go button.
=== Turn off laser cutter setup[edit | edit source] ===
When you are finished all your cuts, turn off the laser cutter, air compressor, and air filter.
=== Clean up[edit | edit source] ===
So that our laser remains operational, it is important that we clean up after each cut. Clean off any debris that can be found on the the laser cutter bed. Using the handles on the front of the laser cutter, open the front of the laser. Empty the debris tray and replace it.
