While working on the frame I also filled out some more of the design details. This included the design of a new hotend mount such that the hotend could be mounted to the small linear slide. It's based in part off of the E3D bowden mount I had designed for my Printrbot LC. However, this version can fit TWO E3D hotends side-by-side for dual printing. I'm still not fully satisfied by the design and may revisit it later to add wire routing options as well as adding a mount point for an auto leveling probe.
Moving forward, there's still quite a bit of work. I've already purchased the last of the "hard to get" materials, which should arrive by next week. My next goal is to get the H-gantry operating. Before that can fully happen, I need to build up some of the external shell. This includes a base below the printer for the electronics to hide in, the side paneling, and the motor mounts. Once the H-gantry works I just have to get the Z axis built, and then the major mechanics are finished!
