I did a multiple part print today and it worked out well. You just need to make sure that the higher parts are printed last because of another bug in CP6: Printer head crashes into center object when printing sequence is by object
Otherwise it works well, just be sure if you set the plate to print by object you move one object slightly (to see the borders fit):
because only after that the slicer will rightfully slice the different objects.
p.s.: On the picture the red part is printed first, if the orange part yould be printed first the printer would crash into the orange part when he switches filament to the red one!
I painted in yellow approximately the path the print head would go on filament change and if any old part is in it’s way it crashes into it!
