There is nothing as much fun as learning to use technology to help you create new projects. It’s what drives us to build the best CNC Router kits we can for our customers. So, it’s no surprise that one of the questions we often hear is if we have a Laser accessory for the Evolution 3, Evolution 4 or the KL series.
Laser cutting and engraving is a great CNC application. While it seems logical for BobsCNC to manufacture a laser engraver we have chosen not to. And since our CNC Routers were not designed to be used for CNC laser engraving we don’t recommend modifying them. For us, the issue is customer safety. The 100-watt C02 lasers we use for production are specifically designed to contain not only the material we cut but also all the laser radiation in a safe environment.
While most hobby machines don't use more than a 5-watt laser, whether it be a diode or some other type, the risks for burns or possible eye damage are real and extremely serious. The safest course for us is to encourage our customers to look for products specifically designed for laser engraving.
A word about eye protection. There are a number of short videos on YouTube that address lasers and eye protection, they are well worth watching. If you are going to operate a laser engraver remember three simple rules. 1. Always wear eye protection that is rated to filter out the wavelength (color) of the laser you are using. 2. Only use eye protection that guarantees an Optical Density (OD) of 5+ or more. 3. Avoid all direct and reflective contact with a laser beam. Never underestimate the possibility of an eye injury. Damage to the cornea or worse to your retina will be permanent.
