Y-axis moving on UM2

I am having trouble getting my Y-axels moving back and forth on one of my UM2s. Here is a short movie showing it "in action":

Anybody have any suggestions on how to solve this problem?

Yes, fixing it is pretty simple.. You just need to position the head in the x-direction, so that the grub screw on the rear pulley on that rod is facing down into the body of the printer. Then loosen the grub screw on the pulley. Next push the axis rod all the way towards the front of the machine, and while holding it there, slide the rear pulley and spacer tight up against the rear bearing. Tighten the grub screw again. Now the rod can't slide back and forth any more.

I find that a ball-end 2mm hex screwdriver is ideal for tightening these screws - much easier than the standard Allen keys. Something like this:

Additionally, it looks like the LED strip wiring in that corner is rubbing on the other axis' pulley. Push that out of the way so it doesn't catch. You can put a drop of superglue behind it to stick it to the front plate and hold it out of the way if it helps.

Loosen the set screws on the pulley, push the rod into place, push the pulley as far as it will go against the body of the printer and finally re-tighten the set screws. Rinse repeat on the other side if necessary.

edit: Dammit

Thank you both. That was really simple
