Prusaslicer: [Feature Request] : Allow free Z placement of object

[benkayuk]

It would be a useful feature to allow an STL to be imported, and for there to be an option to allow free movement of the object also in the Z direction.

This would allow objects to be stacked. A typical usage case would be printing an electronics enclosure box, say with a base thickness of 5mm.

Secondary STL's (for instance mounts for bus-bars, Wago connectors etc) could then be imported into the same project, raised up to a Z-height of 5mm, and placed within the enclosure box, such that a one piece print is achieved.

Currently, the secondary STL's are locked to the bed-level height, and therefore 5mm of the STL is "lost" within the thickness of the first "main" STL.

You can stack objects if you load the other objects as volumes (parts) of
the first object.

Thank you, I was not aware of this as a method...it works, as long as advanced or expert modes are selected.

[bubnikv]

you can, either by entering the numbers in the transformation matrix table,
or by selecting the volume in the side panel, and then dragging the volume
in the scene.

This method, unless I am doing something wrong, still does not allow the
added "part" to be moved in relation to the main object?

If I import main object, then right click - add part...I cannot then edit
the second parts location relative to the main object

Does it fulfill your needs?

[benkayuk]

Yes, it works. It would be great if there was a way to "snap" objects together. For instance, I'm putting the flat base of a part, onto the upper flat surface of another part. At the moment I have to drag very carefully or manually input the z height....then slice to make sure it's not too low or too high by viewing the g-code layer by layer.

In a similar way to how you can snap an object surface to the bed-level, it would be a very cool feature to allow this between volumes of an object.

I have a different use case, but the ability to stack objects would be useful. In order to increase productivity, I need to stack layers of parts to be constructed. That is, a layer of parts, then a small layer of support material, and then another layer of parts, and so on. However, without the ability to move a part off the bed, this is not possible.

This is possible in Simplify3d (Image attached).

@mgg4 Would you ever use such a feature to "increase your productivity"? I personally would never do that, I would rather restart the printer.

@benkayuk snapping objects together is a completely different animal from the original request.
