Laser Blowing System

Laser Blowing System Updated the entry due to the fact that it became unavailable Laser Engraver Project Laser Engraver Update Laser Blowing System Rotary Axis for Laser Engraver Update Laser Engraver for Rotary Axis A little bit of theory ... Solid-state lasers were not originally created for engraving, and even more so for cutting materials, but it just so happened - they can ... They engrave well, and cut more or less, but to improve the cutting process, you need to intensively blow through the burn-through. The laser is not very powerful 5.5W, some materials need to be cut in several passes, and after the first pass of the beam, coal forms in the groove and the gap is too narrow for oxygen to enter, because it is a combustion catalyst. That's why a very simple compressed air supply system was created. Also, the blowing system is very good at removing smoke, which can smoke the laser focusing lens during cutting and engraving. Due to the fact that my compressor is designed for an airbrush and has a small receiver, I made the delivery system so that it would be efficient in working with this compressor, and it worked. I used a copper tube, 2mm thick and 1mm inner hole. They are used in refrigerators and air conditioners, and of course they are easy to find and buy. Fittings for soft tube used for a diameter of 4 mm with a M6 installation thread. I printed the fitting for connecting the quick-release connector, since there was no adapter with the required thread available. I ordered it for the future, but I also prepared STL it for a metal fitting and a plastic one that can be printed. You can see for yourself how this time the burning takes place on the video. This time I used several materials that I was often asked about cutting after the publication of the previous video. As for the cut itself - in principle, I could cut each of these materials in one pass at a slow speed, but the cut quality is much cleaner, if you make two or more passes at a higher speed, th
