Only cut on flat, pre-approved material (wood, cardboard, acrylic, etc. ) If you're unsure if a material can go into the cutter, ask a teacher.
Watch the laser cutter while your work is printing (feel free to bring your laptop over and work while watching).
If a fire starts, pause your print and call over a teacher.
Before using the laser cutter, you need to make an Illustrator file with the design you want made. Check out the Illustrator page to learn how Illustrator works.
