Ok there was some issue with the x/y squareness. It is corrected and I made a test, seems to work on the small part... I will launch a bigger part tonight and tell you how it went tomorrow!
For the other questions, yes, it tends to be worse at the bottom right of the glassplate.
How did you think of the squareness?
Thanks a lot!
(I will mark "best answer" when all the tests are OK, I became a bit paranoid with this machine...)

Check if your machine x/y is square

The process is the same on um2 than umo+
Also. Does that happens near the area where the bowden curves more? Is the spool at almost the end? (That can increase the friction making fluctuations on the extrusion).
Anyhow probably someone else has more ideas.
Edit: Did you said Unilube on the rods???? You mean Only on the Z screw right?? All the other smooth shafts only require sewing machine oil.
Also, is the feeder clean?
