Hello, First time posting just recently found the open builds site and am intrigued. I have some ideas for various projects I am looking at building. I have an idea and question about a couple of the technologies involved. I have seen the various projects and the setup for the linear rails. I was wondering if the cBeam could have the open rails added to the vSlots on the faces with the v pointing away from the center and at that point a ball screw could possibly be used in the channel with the wheels running on the open rail on the out side. Is the open rail not very widely used at the point? Thanks
