Bambu Studio crashes after slicing – solved (NVIDIA problem)

Bambu Lab Software Bambu Studio

I had a problem with Bambu Studio crashing every time after slicing for large models. I have an NVIDIA graphics adapter, and I found a driver setting that got rid of the problem – now it never crashes even for very large models.

The setting is called “Threaded optimization” and you have to turn it Off.

There are several ways to apply this setting under the NVIDIA Control Panel. One can do it globally for all programs, but I choose to do it only for Bambu Studio. In the NVIDIA Control Panel, go to “3D Settings → Manage 3D Settings → Program Settings” and add Bambu Studio to the program list (if it is not already there). Locate the setting called “Threaded optimization” and turn it Off.

Thank you!!! This fixed the crashing I was having on a fairly simple model that I was slicing in vase mode. Never would have thought it could be NVIDIA related.

I’m glad it helped!

Grateful thank you from me as well - was completely unable to do anything useful with Bambu Studio 2 (with new H2D) as it crashed on 90% of slice/send operations. The NVIDIA settings change fixed it immediately, much more helpful than the support response I had.

Good to hear! I have notice some stability issues lately with Fusion 360 when running simultaneously with Bambu Studio, I don´t know if it is related to the driver setting. But Bambu Studio still works fine all the time.

Man, this just took away all of my frustration. I had to keep going to my MacBook to slice files; it was a pain. Thank you.

Thanks for documenting this!
Using BBL Studio while we wait for Orca to be H2D-ready & was becoming very frustrated with the instability on my workstation, especially when it worked okay on my old (slow) box.
You saved my sanity… or at least the small amount I have remaining.

Thanks, it also helped my i9, 64 GB NVidia powered machine…

Threaded Optimization: OFF

However , this should be addressed by the SW developer of BambuStudio… as it looks like it is an old / badly adopted GPL engine with not thread-safe way of programming…

Mike, you are absolutely right - the problem is most likely within Bambu Studio, the driver setting just cover it up. I will notify the support about this, maybe it can help them find a real solution.

Thanks

Don’t know if it’s related, but I opened this issue on their github back in April 2023 and they said it’s a known problem:
Bambu Studio crashes hard when using camera view and RTX 3070 Ti Laptop GPU · Issue #1648 · bambulab/BambuStudio · GitHub

@sprior thanks for pointing this out, but I think the circumstances where the BS crashes are quite different. But who knows, it might be the same underlying cause.
