Now that more people are begining to design their own Lasers after gaining confidence from building Bart plans. I though about creating a thread we could also use which contains ethier links to videos on youtube or company websites which contain images and videos of the internals of a laser cutter. I know I have been looking around on youtube at the chinese manufactures websites and youtube videos to see if I can spot how they all tension their belts for example. I have found some great videos which have shown me a lot about how they are put together.
Here is the beginings of my youtube playlist for laser cutters.
