I dont do ABS, so have no direct input, however it's a good idea to use the latest firmware and software as issues may already have been addressed,
the developers are unlikely to go back to a previous version of firmware or software, to address a problem, as they have already moved on!
on your Cube, it looks as if your first layers are unable to shrink as they cool because they are affected by the bond surface to the PEI build plate and heat from the build plate where as higher layers can shrink more. because they are not constrained and less affected by heat from the build plate
is your printer in an enclosure?
If you don't have an enclosure, try putting a large cardboard box over the printer whilst it is printing and see if you get better results!
I try to make suggestions that I believe to be well founded and safe,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.
