... unless you have the same problem I have (and some others).
I cannot level the bed because the back-right is lower than the back-left. Something that should not be possible but it is in my case. No problem for smaller objects but I'm now trying to print an object with the maximum dimensions for the UM2+.
The right back corner does not stick all the time!
So, an auto-leveling that takes a not-so-good build plate and compensates for the un-alignment would be so nice!
