A while back I’ve bought a J Tech Photonics laser add-on for my X-Carve CNC mill. It wasn’t cheap. I paid €405 for the complete set. This included: The laser and driver module, the 3D printed mounting kit + fan and a pair of safety glasses. The laser set: taken by Robosavvy
The installation Mike Merzke at Merzke Custom Woodworking has made a great video showing his installation of the laser kit to his X Carve.
