# Laser Cutter

<p class="callout warning">Reading this page does not replace training. You must be checked off on this tool before using it.</p>

The laser cuts and engraves sheet materials using a focused beam. It is self-serve once you have been trained.

<p class="callout warning">To be confirmed: the full operating procedure (model, startup, focusing, job setup, ventilation, shutdown). Only the rules below are sourced so far. The machine's details are in Atlas: https://atlas.waukeshamakers.com.</p>

## Certification required

Yes. See **Training and Certification: How Certification Works**.

## The rule posted on the machine

**Never leave the laser unattended while it is running.** Stay with the machine for the whole job, watching it, not just in the room. Lasers can set the material on fire, and a small flare-up becomes a real fire within seconds when nobody is watching. If you need to step away, pause or stop the job first.

## Before you start

- Do the general checks in **Training and Certification: Pre-Use Inspection**.
- **Check your material.** Only cut materials on the approved list, and never cut anything you cannot identify. See **Digital Fabrication: Laser-Safe and Prohibited Materials**.
- Make sure the exhaust or filtration is running. See **Shop Safety: Air Quality**.
- Know where the nearest fire extinguisher is. See **Shop Safety: Fire Safety and Hot Work**.
- Clear scraps and leftover pieces out of the bed.

## While it runs

- Watch for flames. A brief flicker at the cut point can be normal; sustained flame is not. Stop the job if flames persist.
- Do not open the lid or defeat any interlock while the laser is firing.

## When you are done

- Wait for the smoke to clear before opening the lid.
- Remove your parts and all scraps from the bed. Small scraps left behind are a fire hazard for the next job.
- Report any problem; see **Shop Safety: Tagging a Tool Out of Service and Reporting It**.
