Sloped printing when printing dual parts

[tomasf]

Hi,
any idea how do resolve this problem ?
Printing a single box works fine.
Printing two boxes at the same time ( command "copy object" ) gives a sloped result...

That looks very strange. Could be step loss, if the gcode is alright. Maybe try printing simple cubes to test?

if its object position depending then maybe your table turns/rotates in x/y when moving in Z
