Same issue here after updating to v1.10.0 this morning. In my case I think it's when I have more than 1 plate in my design file.

If I have all my models on a single plate and hit slice, everything is good. If I add a new plate and drag 1 model to it then slice that plate, performance drops to like 1fps and I can no longer pan around the camera on the preview tab.

I'm on macOS Sonoma 14.6.1.

I rolled back to the previous version.

Same issue here after updating to v1.10
I'm on macOS 15.0.1 .

Same macOS 15

[mikegabriel]

For curiosity, is everyone on an Intel chipset or do we have issues across both Intel and M series?

I'm on an Intel I9 2.3GHz.

thanks all for reporting this issue

@sagatxxx @northdakota @aayevtushenko @HO44-PROJECT @mikegabriel @zanuda2raza @WangNingkai

do you also meet this issue with the same steps with @mikegabriel ?
if using only 1 plate, is the performance ok?

Yes, after adding new plate - app become unresponsive

[Haidiye00]

Hello, we suspect it may be a problem with the graphics card or graphics card driver. Could you please provide your graphics card model and driver? Thank you

[lanewei120]

Hello @northdakota
we have tried on our mac mini and macbook, with m1, m2, m3 chipshet
can not reproduce it

could you help to record a short video for the detailed steps
and could you help to upload the logs here?

Hello, can you switch the language to English, then close the software and reopen it to see if it works properly

[CodeByZach]

Hello, can you switch the language to English, then close the software and reopen it to see if it works properly

I have the exact same issue and I'm using English.

[northdakota]

Hello, can you switch the language to English, then close the software and reopen it to see if it works properly

I've swithed to English, restart app and issue still happened.

Also i've tried to create a new project instead of using old one.

• Created new project
• added random stl file to single plate
• slice
• all ok
• create a second plate
• copy and paste model from plate 1 to plate 2
• slice
• issue reproduced again

[northdakota]

Also i don't see any anomalies with CPU and GPU
First spike - it's opening Bambu Studio
When reproduce the problem - no spikes

[FiredEgg-bambu]

@northdakota Try reducing the screen refresh rate to 60Hz?

[Haidiye00]

Hello, can you take a screenshot according to this? Thank you~

[Haidiye00]

Hello, can you help test this method? Follow the screenshot to close the two boxed options, then restart the software and help test if there are still any issues? thank you

[HO44-PROJECT]

Hello, I just woke up (UTC+1) and discovered I'm not alone!
Thanks for the suggestions and investigating.

I disabled these two boxes, restarted the software.
Open, slice... very quickly
Once in preview, the problem appears.
View change (i.e., preview to device) is about 5 seconds.
Unable to move the plate with the mouse in preview

I also made the test to work with a single plate project and yes, the software acts as expected with one plate.
I added a second plate with a second model, the software hangs

[WangNingkai]

Close the two boxed options,There is no change.

[FiredEgg-bambu]

@HO44-PROJECT can you please take a try to change the resolution or reduce the refresh rate？ Thanks for your help！

[HO44-PROJECT]

Changed from 60 Hz to 50 Hz, problem is here
Changed to 720p, problem is here
Changed to another resolution, problem also.

I've restarted the studio between tests

The problem still appears once in preview, just after slicing.

[nakedgremlin]

Hi @Haidiye00 I've been tracking some of the conversation on the two thread covering this issue, and I did uncheck the two boxes noted in build 1.10.0.89 and it's still showing the same behavior in the Preview screen -- slow movement, software hang identical to @northdakota and @HO44-PROJECT .

This only happens on projects with more than one build plate.

I'm also on Intel Core i9 2019 iMac, display is 50 Hz.

[HO44-PROJECT]

My complete configuration. I have two displays. I made the test with either one or two connected

Can you provide your email address? We will send you some beta installation packages, and we need your help to locate this issue. Thank you very much

Same here. it just hangs out with a "beach ball of death" after I hit the slice button. Especially with projects with mltiplу build plates.

1.10.0.50 same issue

[northdakota]

1.10.0.50 issue present

[HO44-PROJECT]

1.10.0.68 same issue too, sorry.

[HO44-PROJECT]

I noticed that if I go back to the "prepare" tab, then the "preview" tab, then I can now move the object.

This is my test case:

1. 1.10.0.68 fresh install
2. Open an existing project with multiple plates.
3. Slice the first plate, studio goes to preview
4. Application doesn't answer, can't move the object in space
5. It takes about 30 seconds to go back to the "prepare" view while showing the "spinning wheel cursor."
6. Choose the view tab.
7. Application is now answering

[QZBT]

The same situation occurs on Macs with Intel CPUs.
When slicing is completed, staying on the preview interface will become unresponsive.
If you can click Return to the Preparation Page, it will return to normal.
Temporary solution: Click Return to the Preparation Page as soon as possible before slicing is completed.

[mikegabriel]

I reinstalled 1.10.0.89 this morning and did a bit more testing and for me it does seem to take a significant performance drop the second I add an additional plate.

If I start with an empty file, right click the build plate and add a primitive -> 3D benchy and then slice, everything performs normally.

Now If I click Add Plate and then reclick my first plate so it's active, drag the benchy so that I can click Slice plate again, it's completely unusable in the preview tab and beachballs.

Here's a video of the above: https://github.com/user-attachments/assets/9c523c28-ad98-4f28-904b-ab95ac7c98ac

[refk1]

Issue is FIXED for me: I had a huge lag problem (spinning pizza) and similar issues as others mentioned. I restarted my Mac and still had the same issue. I restarted again and with no apps open, I ran the CleanMyMac app and opened the slicer and now everything seems to be working like normal. Perhaps it's a cache issue. I was also seeing issues like the attached image. Have not tested to see if it's still doing it after running that app.

[refk1]

https://github.com/bambulab/BambuStudio/releases/tag/v01.09.07.52 Could you please test if this version is working properly? Thank you，I would like to confirm again, please

On this version - all looks fine. No hung

I was able to fix the issue by running CleanMyMac after a system restart. No lag and I am able to move the plate around like before. Perhaps it's a cache related issue.

Same here.
Only after cleaning the cache with the above mentioned app I was able to run v1.10.0 without the interface becoming unresponsive, but It was just temporary.

[HO44-PROJECT]

I was lucky enough to be able to help the Bambu guys who worked late to figure out the case. They are friendly and worked late and hard and found the cause. Stay tuned.

[mikegabriel]

Just confirming that the above hotfix preview appears to have resolved the issue on my end. I've opened a few files that all were giving issues yesterday and they are working today.

[CodeByZach]

Talk about a timely response and resolution! More often than not, companies like Apple and Sony allow customer feedback to go unheard. So as not to take for granted, I think it's worth commending when we get things right!

Cheers :)

[mikegabriel]

Yes, I was already sold on the printer itself but the response shown here has only solidified my purchase. This issue could have easily been ignored and I'm sure it would have by many other companies.

Thank you!

[HO44-PROJECT]

I do agree with all of you. Thanks a lot !

The hotfix seems to have resolved the responsiveness problem.

[WangNingkai]

the hotfix provided seems to have resolved the issue.Thanks a lot !

[HO44-PROJECT]

The new version 1.10.1.50 fixes this issue.
A big congratulations to the whole Bambu team

[sxdjt]

Confirming that 1.10.1.50 fixed the issue... and is much faster when slicing multiple plates.

Thank you Bambu!
