Air Assist Nozzle for K40 Laser: A Simple yet Effective Upgrade The air assist nozzle for K40 laser engraver features a clamp that securely attaches to the machine's head using a standard 3mm bolt. This design ensures a snug and stable fit, allowing for optimal performance. The nozzle tip itself is held in place by friction, which provides a reliable seal without any additional fasteners. However, it's worth noting that the small hole at the end of the nozzle tip can be challenging to align with the laser beam, especially if the machine is not properly calibrated. In such cases, the beam may create its own path through the material, rather than passing through the intended hole. Fortunately, trimming the nozzle tip is a relatively straightforward process that can be done to suit individual needs. This flexibility makes it easy to adjust the nozzle to ensure optimal performance with different materials and settings. When printing with PLA or other filaments, we highly recommend using support material to prevent warping and ensure smooth, high-quality results. By taking this extra step, users can achieve professional-grade prints that showcase their creativity and skill.
