There are a few things to keep in mind when using the laser cutter:

• Never use without turning on the extraction! The laser melts through the material being cut and can release harmful fumes. It also causes damage to the machine by fogging up the mirrors and making the laser less efficient.
• Never look directly at the laser beam as it can cause eye damage.
• Always make sure that the laser is set to the correct power and speed, if it is set to too high an intensity it can set light to the material on the laser bed.
• If cutting acrylic sheet remember to remove the protective covering from both sides of the material as it causes risk of fire, harmful fumes and will ruin the surface of the piece you want to cut.
