I´ve got a problem with my UM3 since I printed with ABS.
The auto bed levelling doesn`t work correctly. The distance between the noozle and the bed is:
front right: too far
back right: too small
left side: fits roughly
The only way to get a print is to chance the level with the right screw during printing of the first level.
I also tried manual bed levelling, but this doesn´t work either.
Does anybody has
