My E3V2 worked well for 1 weeks but yesterday i heard some sounds (like a "clac") and my prints were not good on X axis. I tried again today and i keep on listening this sound. For now my printer can't print circles but hexagons !! Do you have an idea about that ???
Also make sure there's nothing (debris) caught up in the belt on the drive, idler or tension gears.
@frenchprinter Please check whether the belt of X and Y axis is loose, if it is, adjust the belt to the best tightness.
