Well at first look it seemed bad but after further investigation it wasnt as bad as I had feared. The Y axis ballscrew has come off the end and some of the balls have come out, so thats the bad. The Y axis trucks were half off the rails but seems the balls stayed in and also looks like there is no damage other than sheared screws on the wipers and a few bent guards.
I also feared the Z had come off the end of the rails and ballscrew but seems the guard had stopped it just before the end so it seems to be ok. Guard is a wee bit buckled but nothing I cant sort.
So all in all a lot better than I had first thought and maybe will even be able to just reload the balls into the ball nut, just have to work out how I gain access to the ballscrew/nut to get it out. I am hoping I dont have to lift it off the rails as that would be a major PITA.
