Taking photos would be a good idea right now. It’s possible that nothing is broken and you just need to factory reset it - or that all kinds of things are damaged. You are standing in front of the printer; we cannot see it. 
Try doing a factory reset and taking a few photos, and then maybe we can judge more accurately; otherwise, we can only guess. Maybe you’ll get lucky and the factory reset will do the trick. This forces the printer to recalibrate itself.
Also check whether everything can still be moved by hand to the end of its range without grinding or strange noises - when the printer is switched off, not when it is on. Check the belt tension, too.
…and if everything looks good, I’ll do a reference run, also known as homing. This can be accessed via the printer menu, the house icon.
