Homing Problem

[dfw3d 4]

My ultimaker 2 seems to be be having trouble homing. I've installed Pronterface and when I move in the X or Y direction, it shows that it's hitting the endstops around the middle of the machine and won't go any further. Also won't return to the home position. On a separate note and hopefully related, I'm getting gaps between the lines in my first few layers. It doesn't happen on the infill, just the bottom and top layers. For this, I've tightened all pulleys, tightened the feeder screw, atomic method many times. I'm hoping all these issues are related. Thanks for any feedback.

UPDATE: I got the line gaps back to normal. Just needed to adjust the build plate a little.

Haven't had any replies so I've just been working off some of the other similar posts. I think I've narrowed it down to my x-stop. I can move +x, but not -x. When I swap cables with the y-stop, I get the same problem on the y. Just want to know if I need to replace the x-stop, or if there could be another reason for this. If so, where can I find one?
