Until I loaded a program and tried to verify with the built in graphics screen. Kept getting an overtravel alarm. Turns out all my work offsets and tool offsets had been reset to machine defaults, all on thier own. For quite some time I've had a G54 all setup for my vise and a G59 preset for an indexer, but had to "find" all of them again.
But this is only the 2nd time I remember it happening.
