I have acquired most of the bits I need to dig in to this project. To really get going, I need to begin the dis-assembly. I am a little apprehensive to dig in as I do not have a back up printer for printing the bits that will invariably come up... So I have come up with a stop-gap. I have already printed off some x-ends that are sized to fit the linear rails of the x-axis and I can put these anywhere along the x, connected to my existing print bed, which will be handy because I am waiting on the manufacture of a new aluminum super-sized bed.

Frame construction is underway.

As for the z-axis, I printed out a coupler to accommodate my larger diameter threaded rod. The diameter of the original rod of the printrbot was 6mm, my new 600mm rod is 8mm. Not a great pic...
