We x y z all working and tolerances not bad. Tied a pen on and drew a line on x and y and seems good using a square.

But I have a bit of a problem with one side of the x axis. As it moves across one side starts to make a noise as though it was starting to bind up. Does not do it in the reverse direction. I have loosened the rails to allow them to move but makes no different. could be the bearings may have been knackered being put of and on the rails as it was built. I have a spare set to try. Disconected and pushing it there is no problem. It probably is the rail/ballscrew tightening.

Have to wait till the weekend now but promise some pictures or maybe video soon.
