Are you printing using print one at a time or print all at once? For the last piece just import another one instead of using multiply.
If you print one at a time:
When moving pieces around you should see a gray shadow on the grid around the selected object representing the free space needed around for the print head to move and not get in contact with other pieces. Move the pieces slowly and you should be able to position the 12 pieces.
You can also try to rotate the piece 90 (around x) to see if you can reduce the required free space around the objects.
Thank you for your comments.
I am "printing one at a time".
I tried "importing one more item" and autoplace moved every other piece to weird locations including off the build plate instead of putting that piece where it would fit in the corner, see image below:
The gray shadow seems much smaller than the apparent Cura rule for manual placement. Please try it for yourself. Everytime I move a part so the gray area is still 1cm away from the first part (and its skirt), the first part part jumps 1cm further away. In fact, try this:
- Place one part on the build plate.
- Multiply that one part 1 copy (a second part will be placed).
- Then grab that second part and move it 0.5cm away from the first part and notice that the first part moves even further from the second part as shown in the image below. Therefore, manual placement does not observe the same rules as autoplace.
Rotating parts does not help in my case.
I agree that I am trying to cram a lot onto the plate, but there have been times when autoplace put a part in that bottom corner and left another location free, so I know it can be placed there. This makes me think there are differences with the autoplace and manual-place spacing rules.
I think I know the problem now; Manual-place erroneously uses the gray area as the boundary for "all" parts even though it should only use the gray area of one part to the surrounding actual part shapes, and Autoplace only uses the gray area of one part at a time to the actual neighbouring parts (as it should) except for some locations like in my example of that corner part.
