Ultimaker 3 passing limits

[Ste_297 0]

Could anyone advise what is going on here.

 

I paused a print as the first layer had failed, during the pause process the head moves to the front of the printer but doing this resulted in the head protruding past the footprint of the printer housing. Normally this wouldn't concern me much but I have a Perspex door fitted to the front of the unit and it has snapped the hinge.

 

What would cause the head to protrude this far past the limits

 

The door needs to be fitted for health and safety reasons in my place of work.

 

Cheers
