I “finished” the CNC router yesterday and have gotten a chance to try it out this afternoon. As you can see in the video, it works ok but it does have some serious problems. I am going to have to rebuild the gantry structure to increase the rigidity and reduce the leverage of the Z axis. Luckily with my new-found experience and of course the help of the CNC router itself, this shouldn’t be too terribly difficult of a task.
