Hi Laurent, I'm rebuilding a 260VMC, the electronics were replaced by Mach 3, but has been as its my first rebuild any other photos you have of it 'naked' would be of great help. Information on these things is as rare as rabbit horns and any that would help keep me from making mistakes would be most welcomed.
PS I have just rebuilt all three ballscrews, Scott Sayers from GMS Ball Ltd ([email protected], 01903 264601) was really helpfiul and extremely knowledgable.
