5 tips for great laser cutting

1. Read all the instructions that come with the laser cutter. You do not want to learn as you go. You can damage the machine if you run the gantry out of the work area. If you can’t figure something out, contact customer service.

2. Never disable any safety features and always wear safety glasses intended for laser use. Make sure all cooling systems are working properly to avoid damaging the laser tube.

3. Make test cuts and keep an operation logbook so you can determine the proper settings and speeds for various materials. This also will give you a baseline so you can judge the performance over time of the laser cutter.

4. Always use the fastest speed and the lowest laser power settings needed to complete the job. All jobs should be completed with one pass. If you use more than one pass, the edges will get over heated and reduce the quality of the cut or engraving.

5. Never cut metal parts or PVC plastic. Metal will reflect the laser and can damage the optics. PVC material produces a corrosive vapor when laser cut, this can damage the optics as well as precision CNC manufactured parts in the laser cutter. Most instruction manuals will show acceptable and unacceptable materials to use.
