So we have this rep 2. Over the weekend I attempted a very slow 45 hours print. It failed. However, the problem is now that when ever the print head comes near the front of the Y axis it starts making grinding sounds. This is to say when its near the front of the print bed closet to the front of the machine. When I attempt to start a print it seems to think the center of the machine is on the left side of the print bed. All the while making grinding sounds. It seems to have some trouble going left. No idea what is going on. I've reset all settings to default. I am going to see if I can update firmware its at 7.5 now. any suggestions would be helpful.

Update. It is grinding any time it moves on the X axis. So when it gets hear the front and any time its trying to move on X.
