Problems with the Y Axis

I've started having issues with my Y Axis motor or the belt not really sure what's causing the issue. I've tried tightening the tension on the belt, that helped a bit, I think. I even took off the T16-2GT pully and made sure it was orientated correctly on the motor shaft and that didn't improve anything. Both times after adjusting I've run the axes self test and the Y axis keeps failing. I'm including a video of the issue, but my best guess is the Y axis or the carriage is out of alignment maybe. I'm unsure since I've only had my printer for little over a month. 

The first video is when the issue started and before I adjusted tension on the belt. The second is after I adjusted the belt and made sure the T16-2GT was oriented correctly on the motor shaft.

I found the issue, and you guys were right. I was just looking in the wrong place. I was checking for something blocking the carraige or the bearings from moving. What I didn't consider was the cord to the heatbed preventing the Y axis from moving all the way forward. It was getting caught on the BuddyBoard enclosure and caused the Y axis to fail every time. If I were paying more attention I would of noticed. Thanks everyone for your help!

Realized I didn't include the videos correctly in my original post.

RE: Problems with the Y Axis

It look slike something is limiting the distance that the Y axis can travel  can you see if anything is stopping full length movement of the Y axis

 

I try to make safe suggestions,You should understand the context and ensure you are happy that they are safe before attempting to apply my suggestions, what you do, is YOUR responsibility. Location Halifax UK...

I looked everywhere and can't find anything that might be preventing the carriage from traveling all the way back and forth. Could the belt being too tight cause this issue?

RE: Problems with the Y Axis

Try to re-flash the Firmware, there is something wrong either with the Y homing or Y axis length set. What does say the Y axis test result?

When the printer homes, for the other end move  it is calulating the number of steps to reach the end of the oposite Y position. If it homes earlier than at the start of the sheet, than it bumps to the end and the the motors skipps the steps creating this "nice" sound.
