What year and which controller do you have in that Precix? I have a controller and extra new boards for mine. I've spent thousands chasing a Y axis problem only to discover that the main program in the QNX software had an error in one line of setup code. I have since dismantled my machine, kept the electronics and the tabletop. My machine started to freak out after I machined a 1" cast aluninum vacuum top for it.
