    Parts list has been added. Plate drawings to be added soon!

    By chance are you going to have a CAD model of the assembly sometime soon?

    Years ago I worked on a design for a part transfer system using linear rails and ball screws and now that I'm building a machine for myself my first one will be based on wheels and extruded aluminum rails and gantry plate assemblies and as we all know ball screws and linear rails will work better.

    After I get my first machine built my next endeavor will be similar to yours.

    The best I am going to be able to do is post models of the plates that will be used. I am not going to CAD model the machine assembly.

    The plates are almost completed, however untested, so when I post I will caution everyone on that.

    Perhaps I will model the assembly in my spare time...I’m trying to plan for the linear rails in my head. To me it seems if the design incorporated the linear rails mounted to the extruded aluminum rails the design will be very rigid but maybe kind of big. But if you saw a real CNC machine it would maybe help make it understandable as to why industrial machines are relatively accurate.

    Looking very nice. I'm currently building a very similar Z axis. Those bearing blocks look like a mucher nicer fit than the ones I crammed onto my machine :p

    Thank you! I'm trying hard to make this happen. Really a great learning experience. Appreciate the feedback!
