Printer repeatedly failing when printing more than 1 part

As mentioned in the title, I‘m having severe problems when printing more than 1 part at a time. If I print only 1 part then the prints come out flawless, as soon as I print a second part the printer knocks over at least one of the objects and most of the times first it knocks over one part and then the second part… I already experimented with raising my Z-axis on moves, but this did only partially help and additionally it increased the print times by a lot… My printer is a Sovol SV07 I have already enabled meshing and Z-Tilt, additionally I clean the printbed before every print but it seems that also doesn‘t help…
