It has been a while since my last update, but work on the machine has been ticking along slowly. Family and work commitments mean that I can only get the odd hour here or there to work on it. The gantry is the largest moving part in the machine. It rides back and forth on the longest axis and moves the z-axis carriage from side to side. At this stage I decided to paint the MDF using a semi-gloss paint; the machine was still in pieces at this point and I figured I wouldn't want break it up when it was finished just to paint it. It took a while to line up the pipes probably due to my inaccurate cutting out of the pieces, and I had to sand the back of the z-axis carriage slightly where it was binding.
