This is my dads machine, he knows hes a idiot and just wasn't thinking.

He had the piece too wide so it was hanging over the side, screwed it down to the spoil board and when he jogged it to go for his pick up it hit the wood. When he took the board off and went to home it, it touched the home limit on one side but not the other, now we can't jog anything (X, Y or Z). I'm assuming the table is out of square and the gantry is out of alignment and he has to fix the table and probably take apart the gantry and put it back together so everything lines up again. Thats just a guess though, did anyone else make this mistake and know how to go about fixing it. I don't know how the sensors work, so even if something is out would that stop all the jogs to stop working?

Any help would be appreciated, thanks.
