While mounting

  • Hi, i received the Printer Tuesday 5 dec.
    I'm mounting it but i encountered a big issue.
    The Thread of the 18B piece (and the twin piece) does not fit with the M3x20 screw.
    While trying to screw it... the screw loses its fillet.
    What i'm missing?
    Is there the chance to have the two piece replaced instead of re sending everything back?
