I'm trying to finish up the fabrication and assembly steps of the printer quickly so that I can move on to test runs. I finished assembling the Z axis structure this week and mounted it in the frame. I probably over-engineered it a bit, but the stiffness of the table is very critical to the precision of the print. I can always go back lighter an cut out more metal.
Unfortunately my cable routing scheme interferes with the Z axis motor, so I'm going to have to drill new holes to route the cables. The Version 2 design has the X/Y plate flipped which will make cable routing *much* easier.
Next steps are to CNC mill the aluminum build plate assembly and extruder motor assembly. I've 3D printed a mockup of the head mounting plate to test the design:
