As you can see from the photo, when I’m trying to print quite large holes with supports, the walls near the top surface are dragged inside pushed by the movement direction of the nozzle. This ruins the accuracy of the print of about 2 mm on a 30 mm length which is insane. It doesn’t matter what kind of supports I use inside the box, the walls are still pushed inside of it.
I think this issue could be possibly be fixed by changing the orientation of the first ceiling layer but I did not find an option in Bambu Studio to do so.
The first ‘ceiling’ layer is a bridge, light blue in color. That’s a big ole bridge, it’s not going to work out well imo, it looks like 10-15% support to support it.
I’m confused by the pictures, hard to tell which orientation is which but it looks like the left side of the picture of the printed part is sucking the two opposing walls towards it.
I think we need more info and some better pictures / angles of both the part and the slicer view to better understand.
All in all, if you can’t find an orientation to avoid that massive bridge it might be a bit challenging but shouldn’t be impossible.
I changed bridge print orientation and put a 3 mm wide 30% infill 3D honeycomb around the walls, now the accuracy is 1 mm off instead of 2. Well, it’s something
