K40 laser path adjustment helper

thingiverse

I made a huge cleanup of my K40 laser, and I needed to adjust the laser path afterward. To do this safely, I decided to use a safe laser pointer before loading 40W of laser power into it. To achieve this, I designed these small disks to hold a small laser pointer exactly in the center of the tube space. The design is suitable for a 10mm laser pointer, the same type used in those machines. Firstly, you need to print one piece with a hole, which will be placed near the first mirror in the bracket. Then, you'll require two pieces of laser pointer holders that are mounted together in the second bracket. Once the laser pointer is powered on, you must adjust its beam to align with the hole in the first piece. After this step, you can safely play around with the mirror alignment until you're satisfied with the result. This method may not provide the most accurate alignment, but it will give you a great starting point for safer work with the real laser tube. Fortunately, this approach worked perfectly for me on the very first try.
