Here is the 3rd installment of the rep-rap build. I've had this done for a few days but only had the time to update on it now. The Y-axis bed is installed along with the motor, pulleys and belt. The belt will need a final tensioning with a small tensioner but it moves freely and is basically done.
After the Y axis was done I moved on to installing the Z axis.
The clamps were squared up and even and the smooth rods with printed bearings were installed.
After that was done the threaded rod was installed to drive the Z axis. The rod and nuts are installed on the Z bracket along with a spring to provide tension and avoid the nuts from pushing back out.
The motor to threaded rod couplers were installed and the motors were mounted and a quick test by turning the rods by hand was done to make sure they worked.
In part 4 I'll be installing the X axis motor and the extruder base.
