Finalize the 380mm underside crossbeam.
Take the temp front 30x30 corner bracket off the underside crossbeam. Sandwich a 16mm M5 screw into a corner 30x30 bracket, the Tower Bottom Brackets Crossover Merge part, the steel plate bracket into the crossbeam extrusion and the base part.
On each side of the 380mm crossbeam attach the vertical 355mm extrusions. This should be attached with a corner 30x30 bracket, and the Tower Bottom Brackets Crossover Merge parts.
On the back of the vertical extrusions install the Z Axis Motor Bottom Right and Z Axis Motor Bottom Left parts. The bottom of those parts should be exactly 44mm from the base of the printer.
NOTE!: The y idler and motor mount are on the wrong side here. swap them!
Install The 320mm Z Rods in the Z Axis motor parts. Align the rods flush with the bottom of the motor mount. Use a Z-Rod securer to secure the rod. This part should contain a hert-sert part with a 16mm M3 screw to tighten it to the rod. Mount the securer to the motor parts with a 12mm M3 screw and a 16mm M3 screw where it also mounts to the z-motor astrosyn dampener. Mount the other side of the Z-motor with a 12mm M3.
Continue with the X axis gantry.
