Hey All! I just got my new Ender 3 on Friday and it's been doing great! However I bought the tempered glass bed as well as better springs, but, I have been having difficulty with the bed leveling calibration since, and I'm not exactly sure what's going on.

Mostly I've been having an issue in the front left corner using a 5 square bed level test print I grabbed from the Tomb of 3D Printed Horrors on youtube. It seems to print the skirt without issue, but as soon as it gets to the lower left square (the first square it tries to print after the skirt), I get results similar to...

One corner failing

... I've tried a few times. It seems the PLA is not adhering to the bed initially and screws the whole square up. The others seems to print fine. I've tried raising that corner and lowering it with no success.

It could be that I just need to clean the bed, but I don't have any alcohol at the moment. I'd need to go out tomorrow to get some (which I plan to do), but other than that...

Any suggestions?
