I took my idea from this video, https://www.youtube.com/watch?v=0BgHm7daDY0&list=PLoFLvlE8fuJW8SfWxZ-plQjTgZi5nN3PB&index=10 i could not do exactly the same because i have laser that is mounted to the machine all the time so I designed a bracket that is bolted onto the laser using existing screws. my laser is NEJE A40640 and laser i used is Amazon.com .
