Core XY update 2.5

Just a quick update

Its alive!  Well X and Y are doing the coreXY thing

I had real issue getting the X axis to move as nicely as I wanted. It would move but was stiff. I wanted the axis to be 'loose'. ie without belts if the printer was on its side I expected the head to move down towards gravity, same as Y does.  After a lot of mucking about I worked out that the top right (in the above image) mount of the X carriage needed a shim. Two pieces of paper where enough to bring it into alignment.

The next hurdle is the heated bed. Its on a 3mm piece of aluminum,  so the instant you try and solder it all the heat is drawn away.
