Unresolved Uneven printing

Hi there a few things to check.

1. make sure your microswitches that support.the x axis are correct by doing a paper level.
2.ensure the bed is seated correctly (there are magnets that hold it in place sometimes the.bed gets shifted

 

Indeed. @Geof is right.
Auto bed leveling will help, but not absolutely cure, an un-level bed. If it is too far out it will simply give you the best average it can.

Manually leveling (at a minimum the X axis) is required to get the best results.

Check out the first video.

 

That may not solve it 100% in your case, since (to my eye) that looks like it may need some leveling on the Y axis.
However the process is the same, but you adjust the Y by adding shims under the bed where the rail is held by the magnets.
Paper shims (small bits of a paper sheet) work fine. (specifically in your case that one corner looks 'low' and might need a shim or two)

Do the X leveling and see if the autoleveling is good enough at that point or if you need to adjust the Y manually.

 

After the x leveling (paper level) mine was good enough but i still shimmed it just because...well im just crazy like that lol. The less the autolevel has to compensate the better
