Crazy indeed!
Before your edit you told that it crashed into the endstops,
that means that it probably looked at the wrong endstop pins.
Does M119 report something else this time?
Is it TRIGGERED when you press the endstop?
Or is it TRIGGERED when it has been released?
Are you sure you wired your top endstops to the max pins?
I have seen Ramps examples where people connect the min pins,
but since a deltabot works 'upside-down' that probably won't work.
