Repetier Host 2.0.5 crashes on view gcode generated by Slic3r

guffy

hi
Repetier host crashes on my pc when i sliced with Slic3r.
Steps:
- load the gcode file (as example see link below)
- try to zoom-in/zoom-out with wheel
Also it creashes immediatelly after a model sliced.

PC:
Windows 10 pro x64, 1709 16299.192
Graphics - on board Intel HD 3000 in Core i7 2600K

See first lines in log. You see it selected the microsoft generic OpenGL driver. That one always crashes sooner or later.

So th ebig question is how to convince OpenTK to select the OpenGL driver of your graphic card. On laptops this often depends on the energy saving settings or graphic driver setting. If you set it to full powe rit often switches to use the right driver instead.

guffy

thanks for answer. it's not laptop, it's ordinary desktop pc.
i had guess that it looks like some issue with opengl, but it's interesting that when the application shows STL model or gcode sliced by Cura - it works almost well, no issues with rendering. only gcode produced by slic3r inspires crash

guffy

by the way, i had launched repetierhost.exe from commad line window and didn't see any output from them to the console. is it writes a log to some file? or i have to explicitly eneble tracing by a command line switch?

Repetier

I mean the log window in host, the lower part with the output. there you see it used generic 1.1. Host requires 1.5 or higher to work good. Not sure why OpenTK sometimes does not choose a available good OpenTK driver. That is the library we use for OpenGL visualization. Cura is written in a different language and uses a different library. All I can say is that this often happens when a pc has 2 graphic cards and on laptops and that graphic card and power saving settings can have an influence on it.

guffy

oh, i see - i didn't find most obvious place :)

that's interesting. i don't know how to you initialized and used the opentk, i'm not familiar with opengl and don't use c# last years.
but simplest opentk sample i have made on my pc (added opentk as nuget package) shows that it looks like opentk can use intel's opengl 3.1 on my machine.
And it's true - open gl extension viewer 5.0.9 also says that supported version is 3.1 (driver 9.17.10.4459 from 19/05/2016)

the opentk dll that nuget downloads has version 2.0.0.0
the opentk shipped with repetierhost looks like has version 1.2.2336.6514
may be it's the reason

(i had mean gcode files generated by cura, not cura application itself. those gcodes don't inspire the crash)

Repetier

Intersting. I was using OpenTK.Next which was the official "hot" version with most improvements. Seems like it is not hot any more. Have send you a pm with a test version using OpenTK 2.0. Please test if it works. We use GLControl and not GameWindow so it might still have problems or hopefully not.

guffy

thank you very much for support, especially on weekend :)
i have got your file. it's really has opentk and glcontrol ver 2.0, repetierhost loads it (i checked with process explorer)
unfortunatelly this doesn't help. :(
glcontrol still initialized to use opengl 1.1.
thank you anyway

later i will try to find an example how to build simplest application with glcontrol. i will share results

Repetier

That would be great, because I have no pc with that problem. When I'm back I will post you how it gets initialized at the moment.

Repetier

Here what I use:

if (Main.main != null && Main.main.ThreeDSettings.AntiAlias) mode = new GraphicsMode(mode.ColorFormat.BitsPerPixel, 16, 0, 4, 0, 2, false); mode = new GraphicsMode(mode.ColorFormat.BitsPerPixel, 32, 0, 4, 0, 2, false); gl = new OpenTK.GLControl(mode,1,5,GraphicsContextFlags.ForwardCompatible);
differs if antialias is on or off (hope you have it off).Important part is double buffering and RGB color.

Repetier

Just forgot, there is no official GLControl working with 2.0 so I used OpenTK.GLControl_IK which matches and works (ok for me:-).

guffy

hi
I have made the sample. it looks like it works well.
I also had used GLControl_IK

packed solution https://drive.google.com/open?id=1Tpteo_T3JTOvEd0RDWubGEaLLkNhJUIg

guffy

that's funny. i have changed initilization code as yours, but it still work properly.

i can make guess that may be an additional componet (GDI+?) in your project indirectly initiliaze opengl and then opentk fails

guffy

byt the way. i had tested repetier host you had gave me on my work PC. it corretly detected opengl 4.5 on intel hd 630

Repetier

Have rechecked it and I have 2 versions and copied it from the unused :-(

Th eone used uses just new GLControl(mode); that has opengl context 1.0 as default so 1.1 would match. Have now changed it to use 1.5 forward compatible in the hope that it then is forced to use the real driver, which seems to work for you so my hope is that this is the reason.

Have send you a pm with download link for testing.

First, thanks for an awesome printer application!

Unfortunately, I also have this problem, it worked previously, but no longer for some reason. My CuraEngine slicer works fine, but Slic3r crashes the application.
I use an older computer together with my 3d Printer with an Intel Core I3 M 330, running Windows 10.
Intel no longer supports this processor and hence not a driver for the CPU build-in graphic adapter on Windows 10 so that it can run OpenGL. So I have no way of Getting Open GL up and running, or don't know how.

Is it not possible to handle the exception in the application. Or, alternatively implement a 'top level exception handler' so that the application does not crash?
I also use Repetier Host v2.0.5

Repetier

What does slic3r crashes application mean? Crashes slic3r or does host crash when reading the sliced result?

In the later case you can disable filament and travel visualization (in toolbar the 2 eyes) and it will not try to show them and should hence not crash. Drawback of course you see no preview but that can only be solved by having a OpenGL driver > 1.5. For printing you should confider using repetier-server so a crash of host does not stop printing. Host can print and connect to printer through the server.

guffy

hi
unfortunatelly new version dosn't help :(
the issue somewhere deeper. You properly init GLControl, but WGL somewhy doesn't properly get entry opints of GL functions and doesn't load intel's GL dll
Repeater host (GL control constructor, obtaining entry points, loaded modules):

Test application (i ensured that it also worked as x64 process):

guffy

so it looks like now it's not blame of RH. i guess something wrong with Windows or Intel's OpenGL, but i'm not sure.
I made a test:
1. renamed original repetierhost.exe -> repetierhost1.exe
2. copied my application to C:\Program Files\Repetier-Host and renamed it to repetierhost.exe
3. started both.

Also i copied entire RH to D :\Repetier-Host. didn't help

so it not path, not bitness, not opentk dlls. i have no idea at the moment

Repetier

I only remember it happening with intel HD 3000 graphic cards. Have also an other intel graphic card that works without the problem. So at least this driver is prone of the problem.

Question is still why it works for your test and not host. In your sample you had samples =4 which is not the case for the host unless you enable anti alias in preferences and restart. Maybe worth a try.

The way to wgl entry points seems identical but result differs, so really hard to say why both behave different if everything else seems the same.
