Laser cutters are an excellent tool for cutting and engraving wood and acrylic glass. To get started, you will need a vector file (bought online or created by yourself in inkscape/illustrator) and a laser-safe material. This page will give you an overview over the laser cutter, safety information, and instruction on how to use it. Before using it, you must complete a machine introduction course.

Safety
Laser cutters are dangerous in various aspects. There is an invisible laser beam that can permanently damage your eye. The fumes that escape while laser-cutting or engraving materials are at least unhealthy, in some cases toxic and worst case can cause severe health issues when inhaled. There is also a chance of starting a fire if operated incorrectly.
- Undergoing a training course is mandatory before you start using the laser.
- Do not tamper or work around any safety measures, including the machine activation or laser safety circuit.
- Always (with no exception) supervise the machine or have someone supervise it for you. Do not leave the laser cutter unattended while a job is running.
- Immediately e-stop the machine in case of a fire and after that start extinguishing it.
- Stop the laser job and investigate if you smell or hear anything weird.
- Make sure nobody stays in the pit (performing work, ...) and hang the white/red chain before starting the laser.
- Never attempt to laser-cut unknown or dangerous materials. If in doubt, do not laser-cut.
Laser-cutable materials
We recommend that new users cut/engrave poplar (wood) or MDF. A good list of dangerous and safe materials can be found here. If you are unsure what material it is or if you can not find information if it is safe to laser, always default to 'unsafe' and do not laser-cut.
Preparing your files
- Connect your computer to the "munichmakerlab" wifi. The password is written on the postbox mounted on the workshop door.
- Using the (windows pre-installed) "remote desktop" or (mac, additional software) "Microsoft Remote Desktop", connect to "laserpc" (or IP 10.10.20.81). The username and password are 'makerman'.
- Once connected, navigate to the Z:\laser\ folder and create a folder with your (lab-unique) name or nickname
- Now you can copy and paste vector files (.ai, .dxf, .svg) from your local computer into the folder on the computer
- Open LightBurn on the laserpc (icon on the desktop) and import (ctrl + i) your file
