Hi all I have just put together a video showing how to make your laser pointer position indicator use the same optical path as the CO2 laser beam. This enables much more accurate positioning of the cut and facilitates realigning the laser after the part is removed and replaced in the machine. The idea is not new, since I read about it on cnczone originally, but can be easily reproduced. Usually a beam combiner is needed which is expensive. My solution is relatively cheap and can be made on your laser cutter. Here is the link
