Machine bed not shown

[theprocrastinator 0]

Hi.

When running Cura 5.7.0 or 5.8.0 machine or 3d models are not shown.

Better see the attached pictures.

No OpenGL warnings are shown and 3d drivers seems to be right.

Any hint?

Thanks

• Do they show up properly in Prepare mode?
• Try going to Preferences > Configure Cura..., turn on Force layer view compatibility mode and restart Cura (just because it shouldn't be a problem doesn't mean it isn't).
• If you could go to Help > Show Configuration Folder and attach the cura.log file in there to a post then we can spelunk through that to see if there's anything interesting.
• That looks like Linux (and by that I mean it doesn't look like Windows or Mac). Are you running under X or Wayland? I've heard Cura can have problems running under Wayland (but haven't tested it myself because Nvidia still can't be bothered releasing drivers with decent Wayland support).

1. Both, Prepare and Preview shows nothing.

2. Force layer... turned on. Nothing happens.

3. No cura.log generated. See the attached capture with the content of the folder

4. Yes, I'm using Arch Linux. Sorry for the lack of information. And yes, I'm running under Wayland. But this is the first time getting this issue.

 

5. Many thanks for your fast and extensive response.

Try looking in ~/.local/share/cura (I still don't know why it creates folders in both locations) for a file called stderr.log and then in the 5.8 directory in there for the cura.log file.

 

Also: what graphics card do you have and what driver are you using?

Seems that OpenGL is not detected.

FWIW, I get a whole lot more information in nvidia-settings when running under X:

 

The log file suggests that it can only detect OpenGL 3.2 capable drivers available:

2024-08-30 00:15:06,483 - DEBUG - [MainThread] UM.Qt.QtApplication.initialize [192]: Detected most suitable OpenGL context version: 2.0 No profile

Although since Cura won't use that it just drops back to 2.0 (which is compatibility mode).

But then when it tries to create an OpenGL view it craps its pants:

(repeat a bazillion times)

 

First thing which has probably already been done in the background: make sure you have xorg-xwayland installed (you probably have something which depends on it installed already, but can't hurt to make sure). Not sure if that'll help, but it (probably) can't hurt.

 

You should probably submit a bug report and see if they can help (or at the very least... get it reported as a bug so they can add it to the list of bugs to fix). Make sure to include your system info, the log files, and you should mention that you're running it under Wayland.

 

Also, if you can, try running it under X, and if that works probably mention it in your bug report, although then they might just tell you that it's the Nvidia drivers at fault - and they wouldn't necessarily be wrong. Wayland support in the Nvidia proprietary drivers is still pretty immature (I'm usually a pretty early adopter - why do you think I'm running Tumbleweed?) but even I'm sticking back on X for the foreseeable future.

I have ran Unigine Heaven benchmark and seems to work right but seems it only detects OpenGL 3.2.0

I'll keep searching.

xorg-xwayland was not installed but installing it doesn't make a difference.

[Slashee_the_Cow 410]

So looks like your system supports OpenGL 4.6 and OpenGL ES (OpenGL for Embedded Systems, a subset of OpenGL aimed at things like phones) 3.2 (which is the last version of it). Not sure why Unigine would (presumably) resort to OpenGL ES (maybe something to do with the "GLRender::GLRender(): Unknown NVidia GPU"?). If Cura is also trying to use OpenGL ES that could be your problem. Unfortunately I can't really help you here as the newest device I have with a mobile Nvidia chip has a GT555M - which is to say "not very new".

 

I could take a complete stab in the dark and say "make sure everything is set to maximum performance mode" to try and get it to favour regular OpenGL but the answer probably isn't that simple.

Good news: it's not just you.

Bad news: it's not just you and they haven't fixed it for other people yet.

Definitely worth adding a comment saying you have the same problem.

 

If your laptop has switchable graphics between the GPU and integrated on the CPU - and most do - you could try using one of the options in this page on the Arch wiki to try and force it to use the integrated graphics and see if that makes a difference.

$ QT_QPA_PLATFORM=xcb ./pathto/UltiMaker-Cura-5.8.1-linux-X64.AppImage

Seems to solve the problem.

 

Models take a lot to load.

Try opening the Marketplace (at the top right), click the gear icon at the top right of that, scroll down to "USB Printing" and disable that. No idea why it works but for many people it fixes that problem.
