I have been away from my machine build for some time now due to an illness. I am finally back in the game and have gotten my laser working and reviewed my files I have for the acrylic limit switch mounts and noticed I only have the X and Y. In the book there is a set mentioned for the U axis? Is this the same as the one for the Y? Also, does this go on the opposite rail on the right front or is this used for an end limit on the left rear?
Thanks for your time
