Good flippin grief...

It was the power lead to the spindle, got snagged on a burr on a piece of aluminium at the top of the z axis.. Sorry guys... On the plus side, when I do make an appearance on this forum, I do seem to make you all sound like geniuses!!!!

Going to have my thumb surgically removed from my ass before seeing if I can create another 'high tech' problem..

Thanks all..!
