See the CO2 laser beam, using the Mahoney brand Visual Beam Alignment Tool

A brief clip showing the CO2 laser beam centered in the cross-hairs. The Mahoney brand Visual alignment tool is mounted on the second mirror mount, while the first mirror mount has its knobs adjusted. With this tool, beam alignment is conducted while the laser is powered on. Buy it and use it to save time because you conduct a speedy beam alignment on your CO2 laser engraver. This tool works on any size laser engraver/cutter, while I show it on the video with a 1500 mm wide by 1200 mm deep.
