All the latest Bambu Studio updates are crashing and unstable

Bambu Lab Software
1

The newest version I can use is 2.6.0.51, and even it has some instability issues 30% of the time. Updating to any newer versions cause studio to be almost unusable with nearly at 80% crash rate just upon launching the software. If I can get past launch, it usually crashes when loading a project or slicing a new project. I will often just launch the program, see a splash screen for a few seconds, and nothing. Fails to launch before I even see the GUI.

What in the world is going on here? I can’t really pinpoint in which version instability become an issue, but when I rolled back 2.6.0.51 was the newest version that remotely had stability.

This happens on both my gaming laptop, and my desktop computer, as well as a buddies computer who is just trying to get into the software side of 3d printing, so I know its nothing to do with one specific computer.

What is the solution here? I can’t live with this instability. Am I going to have to the go the jailbreak/orca slicer route or does bambu have any plans to fix their software or just keep releasing flawed updates that don’t address the issues?

I don’t have any issues.

I don’t know if anyone is going to be able to help you though unless you provide some specifics, such as actual versions you have tested and computer details they are tested on. You have provided specific statistics by percentage but those percentages don’t mean a lot without having the actual numbers they represent.

Again, the only stability issues I have had with Bambu Slicer was the last version and the issue it had with MacOS but after searching the forum I had found that a in-term solution had been provided and this last update has fixed the bug that was causing that problem. I am going to assume you already did that as well though so again I suggest providing more details for those who are more knowledgeable that they might stand a chance of offering help.

All are windows 11 machines up to date with windows updates.

Machine 1: 13900 Intel Core I9, 4070 Ti, 64gb ram and 4tb NVME raid drive array.

Machine 2: 14900 Intel Core I9, 4070, 16gb ram, 2tb NVME

Machine 3: 14700K Core I9, 5070 Ti, 32gb ram, 4tb NVME

Version Tested: 2.8.0 Public Beta - Launches 1 out of 5 times into the program, if successful, it crashes upon loading or slicing a model.

2.7.1.62 Public - Same results

2.7.1 Public - Same results

2.7.0 Public - Same results

2.6.1 Public Beta - Lower amount of crashing, 4 out of 5 times the program launches, will allow me to load a project or slice a model. Still an occasional crash maybe 20% of the time.

2.6.0 Public Release (Hotfix) - The newest version I’m able to run with a reasonable degree of stability. Still crashes on launch under 10% of the time.

Prior to these updates studio had no issues besides the memory leak problem that requires an occasional relaunching of the program to free up the ram it was consuming in extremely large projects (would occasionally eat ~50g of the 64g available ram and not relinquish it after the slicing process was over)

If this was only on one machine I’d consider it isolated, but its happening on every machine I own plus a friends in an entirely different location and network. This is clearly something with the software.

Maybe, but since it’s working on many other peoples’ systems, could you have some specific software or configuration on all of those systems that might be the culprit? You are common to your systems and maybe you or your friend shared something between you both that is causing the issue?

And it doesn’t even have to be recent. Some software doesn’t cleanly uninstall. It could be dregs from a while back.

Just as a question, Bambu has a popup that can appear when you start the program that warns of conflicts with things like nvidia drivers and some other system software. Are you getting any warnings of conflicts?

There is something else you could try. Bambu also makes the software available as standalone, not installed executables. It’s so you can load it on a USB drive and use it on other computers without installing it.

I haven’t used them but this is the link Bambu gives to them. Maybe someone else can point you straight to the zip files themselves. Anyway, the thought is since they are self-contained, maybe they could get you past whatever conflict might be happening. I do think it’s a software conflict though. If it was an actual problem with Studio this board would be lit up with posts.

No conflicts or warnings when launching it. I have made this recent discovery however. The crashing doesn’t start until I install the bambu network plugin. I can install the software, close it, launch it over 2 dozen times successfully, but upon trying to login and subsequently installing the “network plugin”, the crashing begins to happen all over again.

I don’t believe it to be software or config related because we do not have anything common between me and the friends computer. We have some of the same games installed, but thats about it. The computer is in a different state, never been touched by myself, and he has no other 3d printing related software installed yet. He had actually never had bambu studio installed prior to this, and just downloaded the latest version off the main site just to encounter the same issues that I’m having.

I will try the stand-alone versions and see if I have any different results. Thanks!

I’m really having a hard time figuring out why me and my friend are the only 2 people with this issue. I’ve even installed it onto my extra machines to confirm, and the crashes still happen just the same. All on standard, up to date windows 11 installs.

On a side note, I’ve previously tried dealing with bambu support over an unrelated issue where they shipped me the wrong order from the bambu store, and it took over 3 weeks to sort out due to massive communication break down, no follow ups, talking to a different person each time I reply to the ticket, so I have little to no hope they can even comprehend the issue at hand based on my previous experience with them.

I’m not familiar with the network plugin but it’s in there on my system and working fine. I’m not on the very latest version of Studio though. I’m on the last release and not this newest one. And if this was a problem with Studio or the network plugin-in I’d expect a lot of people would be reporting it.

Software is pretty complicated, though. The modern development environments have fingers into everything and that can allow conflicts to emerge even between very different kinds of software. It still could be a conflict especially if something replaced a dll or some other resource Studio or the network plugin also uses. Some “bad” software pulls that bull in a china shop thing and may change or even remove stuff other software relies on.

I have no idea if that’s what’s going on for you but it does occasionally happen. Again, just going by the simple observation you guys are the only ones reporting this right now.

Not enough experience or knowledge to help further. There are crash reports in Windows and those would likely point to where the issues happens and could provide more clues as to why. Bambu will probably want to see them if you do go through their support.

You may be stuck going through Bambu, though. Or maybe some here more familiar can help out.

How up to date is your BIOS? Between my 13900k and 14900k I’ve had my fair share of stability issues with both Bambu Studio and OrcaSlicer. What finally fixed it was one of the latest BIOS updates as well as further reducing the AVX offset in the BIOS.

I’m having issues as well with the beta that don’t seem to be present on the official releases.
