same for me

[MackBambu]

@Laurent-K @nmkr @Hamudulu @benjaminkott Could you send me the configuration file? It’s located in C:\Users\USERNAME\AppData\Roaming\BambuStudio. After that, you can try clearing the configuration file and try again.

BambuStudio.zip

after deleting the configuration file and reopening bambustudio the error still exists

Hey everyone, I found the cause, it’s due to an incorrect string conversion format. Please switch your locale to English for now, and I’ll fix the issue shortly.

can confirm - switching from german to english resolved the issue

[benjaminkott]

@MackBambu can confirm, can now be loaded.

[Laurent-K]

HI, ok I did it and now it works but I had to close and open 2 times.

[MartinChan3]

@Laurent-K Have you tried switch Language to English?

[Laurent-K]

Yes and it works with English language. Sorry if my explaination was not ok. the first time I did it it crashed, but I opened the software again and it works now. Thank you !

[Givaro72]

I tried English but no luck importing a stp file. OBJ works but the only thing what i see is that circles ar not round anymore, but divided in segments. Where to change that ? For now I downgraded to the previous version.

[Steff1964]

Same here, will try English version or downgrade.

[SorenTheSwede]

Can also confirm that switching from Swedish to English solved the problem

[Vespisti1969]

But that cannot be the solution. There are people who do not speak or understand English.

[benjaminkott]

@Vespisti1969 please see https://github.com/bambulab/BambuStudio/issues/5186#issuecomment-2470555626 it´s a workaround until a patch was issued.

[Vespisti1969]

@Vespisti1969 please see #5186 (comment) it´s a workaround until a patch was issued.

I‘ve read it and use this workaround. For me its ok, but maybe other people have a problem to undrstand english well. Im sure that bambu will fix the issue very fast.

[boinjoe]

For me it was not working. Switching from German to englisch made it Wiese. Now the program crashes directly after opening.

Please also add detailed help on the Step File Import Parameters dialog that explains what the impact is of the settings. Mouseover help (like a ?) and detailed help added to the Wiki pages would be helpful.

[MartinChan3]

@boinjoe Can you delete the .conf file under BambuStudio temporary folder and restart Studio again?

Same here.

I will be updating the wiki soon.

[MackBambu]

Same here.

Clean up the configuration file or open BambuStudio.conf, find the lines for angle_deflection and linear_deflection, and delete them. They might have been set to incorrect values.

[3DWORX-SA]

How about using simple, understandable terminology in the dialog like "Higher resolution/detail" and "Lower resolution/detail"? The numerical values can still be displayed and editable, but please it costs nothing to make it easier for users to understand. Thanks

Please use the above version to resolve these issues you may encounter before we officially release the Hotfix version.

[Vespisti1969]

Thanks a lot for the very fast Fix. Works great also on Apple Pro M2 Chip.

The v01.10.00.94 preview (Windows) still has an issue when a STEP file is imported.

The "Loading" dialog is displayed:

Then the Step file import parameters dialog is displayed: (should be STEP in uppercase)

If Cancel is selected, the import cancels immediately. But if either of the settings are moved, and then Cancel is selected, it takes a very long time (with a large CAD model) to Cancel while the number of triangles is calculated - it should also be immediate and the calculation of the number of triangles should be aborted/interrupted immediately. I have had to force close BS to restart (with a large CAD model).

It should also not be possible to enter invalid values - I saw a comment in another thread that this was possible and that a settings file had to be edited to rectify this.

Also, a button to "Restore defaults" (those used before the new dialog) would be helpful. What values are used if "Don't show again" is checked - some defaults or the last selected values?

Thanks

@3DWORX-SA In fact, I have optimized this part. Could you share the STEP file?

It should also not be possible to enter invalid values - I saw a comment in another thread that this was possible and that a settings file had to be edited to rectify this.

If the 'Do not show again' option is enabled, it will default to using the last set value.

[3DWORX-SA]

@MackBambu Sure - but I cannot post it publicly and there's no PM system that I can find on Github - how can I email it to you privately, purely for the purposes of testing this and with the assurance that it will be deleted thereafter and not shared with anyone else?
