Improved 3MF compatibility for multiple printer models: Blows

It would be nice to turn this OFF. I feel like this was a BIG step back for how I use Bambu Studio when printing a single large project, to an X1C and the A1M.

Switching nozzle size, to shrink / enlarge all the plates was fine, when all the PARTS stayed in place. Yes, switching the Printer to the A1M meant the 256 (X1c) plates of parts all overlapped the edges of the now smaller plate. But that’s fine, I already printed it, and may want to print it again, at that size. But now, because all those parts overlapped the the plate when switching printers, it just spreads those parts everywhere. Including stacking them up on each other, and rotating their orientation. WTF?

Print to X1C 256x256

Switch to print some parts on A1M - Seriously?

Not only did it reorient those four pieces to vertical and stack them on each other, but it changed the filament type as well! Seriously?

I get it, the A1M isn’t going to print PC, but I wasn’t going to, I was going to print one of the, smaller pieces, in PLA. This is just terrible.

It also just completely wipes out the arrangement of parts on the left side of the plate section. It used not mess with anything over there when switching printers / plate sizes.

Stockpile of parts - arranged with 256 plates (X1C)

Switch printer and plates -

It just smashes them all together. When you go back to the X1C, they do back to place. Unless, when in A1M and smaller plates, you move parts to the left side from some (smaller) plates. Then when switching back to X1C - The left side parts are again smashed together with the ones you moved while in A1M. And it deleted the empty plates. Moving the other parts up. This just blows, for how I use it.

Please Bambu, give us an option to disable this ‘feature’, and DON’T MOVE parts to the left of the plates. Why would you? Baffling…

I expected this new feature to fail.

It hopes to achieve too much, something you proved by expecting too much of it.

It was never going to resolve models too large for the A1 mini just because you selected the A1 mini.

In an ideal world and what you said at the bottom…

This makes more sense, although I would argue a better solution.

Let the user arrange ll as they used to, arrange by plate as they used to and a DIFFERENT key combination (maybe add CTRL in the mix) gives this new magic pray move.

The problem you have it is needs to be one thing or the other. The A1 mini cannot print the PC type, so it has to be set to something, it can’t be in a temporary state of limbo as you can’t publish that.


I liked the old way, if it couldn’t fit when you jumped to the A1 mini, you could jump back to a full-size build-plate version tweak and it goes back to what you had.

It was a good idea, with a flawed roll out.

The other option, I would settle for, is to have the lock on a plate also lock the size. (And current parts on the plate.) Seems like a no-brainer to me…
