When I click “auto arrange”, all the parts are placed to the left side of the printer bed.
Why are the parts not centered? Is it intentional or is it a bug?
If I’m trying to come up with an explanation, I will guess that the parts are somewhat aligned to the poop chute in the X axis. But is that really the reason? This only happens with the H2D, no? 
One of the great mysteries of the world. I would guess it has something to do with minimizing travel. 
I suppose that the automatic placement of parts in a slicer like Bambu Lab Studio depends on the machine used, the size of the build plate, and the chosen print mode. The software optimizes the space based on these parameters, which explains why the positioning isn’t centered and varies between machines. This helps maximize the build plate surface and reduces unnecessary movement during printing.
Because that’s where the auxiliary part fan is, putting the keel in front of it help cooling the cantilevers
My theory is that it aligns it closest to the camera with a combination of toolhead travel.
