Hey everyone, I am pretty new to this and am searching for help. I want to print with the Ultimaker 3 and use the cura software version 2.4.0. My problem is that I need different models to be positioned all at the same starting point. So something like the front left corner of the models should always be positioned at the same place relative to the edges of the printing plate. Has anybody done this yet or knows how to do this? Thanks in advance!
