Prusaslicer: Auto Arrange, You Have Literally One Job
Prusaslicer: Auto Arrange, You Have Literally One Job
My eye's not twitching. Your eye is twitching.
And it did it's job, didn't it? Are they arranged or not?
"Are you not
entertainedarranged?"did its* job
And you did your's.
Do not question the auto arranger if you know whats best for you
I'm with you, but is it possible this helps in some way with nozzle movement that might not be easily visible? Just trying to figure out why it would even consider this placement.
If I reduce the count one it will arrange them in a neat grid, albeit with one row shorter than the other. And there is an element of randomness, if you click the arrange button again it will sometimes place the outlier on the other side.
I have no idea what the fuck its thought process is.
Make the movements visible in preview. Most probably it makes the total movement shorter when switching between parts.
There may be multiple solutions to the fitness algorithm it's applying. So you may sometimes see one and sometimes the other depending on some "random" variable.
You have the right idea! The slicer takes all printhead movements into account and likely shaves off a fraction of the total print time by positioning one object like this.
Ah... Perfectly arranged, as all things should be 😘🤌🫴
Yeah it drives me a bit insane too. I often end up just manually placing everything. I wish it had a mode where you roughly place things and it spaces them consistently without significantly changing their relative positions
Cura is guilty of this last part too. It'll flip parts around however it sees fit, which isn't ideal because then you get z-seams in all different areas, so matching parts no longer match.
They all printed ok with no interference between the parts. All parts are perfectly usable when they are removed from the print bed.
Why does it matter that they're not in perfectly straight rows and columns?
I think it tries to keep things as close to the center of the bed to minimize travel.
does it matter though? in the end, they all fit and have reasonable distance from each other
It can, but it will depend on the material. I've had much better luck with warping by packing multiple models tightly together when printing in ASA.
If you've ever played Resident Evil or the like, you should know never to rely on auto-sorting. It's never more efficient than doing it manually. :p
Lol rookie. Add the 12th delete the 1st.
Bambu studio (shameless rip off of Prusaslicer) does the exact same thing and I hate it
I wouldn't call it a shameless ripoff, it's a fork. Which Prusaslicer was as well. I'm actually glad they did that rather than making yet another closed source slicer. That means that enhancements that Bambu puts in can very likely be ported over to Prusaslicer, and vice versa. It's a win for everybody.
Which then gave us orcaslicer (fork of bambu) which has been a godsent for having my mainsail UI in the slicer itself.
Nesting is nasty 🙃
Please note that the traveling salesman problem is NP hard, so the auto-arrange algorithm will never aim for a "perfect"/ fastest arrangement. It just ensures that the parts have a minimum distance to each other while keeping them as close as possible to the center of the build plate
