Ianus is born (well the prototype test bed is at least)
Ianus is a dual head Cartesian with Independent Z axes on a common X and common Y platform.
The Y axis is the worktable which is full width and slides backwards and forwards on the bed frame.
The X axis is mounted to the head of the gantry and slides full width.
The independent Z axes are mounted to the X axis on the gantry one per side initially, though this could be modified to present more independent Z axes ie 4.
The tubes and fittings I wanted have arrived and I have assembled them to trial the ideas. I bought the pipe and clamps from http://www.hunts-pipeline.co.uk/ they are located in Normanton, West Yorkshire, UK
