UCCNC screen problems.

Postby jrafales » Fri May 26, 2017 5:57 pm

Hi, I have a issue with the UCCNC 3D toolpath viewer. As you can see it doesn't works and there isn't screen update in it.
Any suggestion?
Computer is IBM Lenovo, Windows XP professional SP3, Graphics Sis 661fx, all updated. OpenGL 1.3 supported. Framework 2.0 to 4 instaled and updated...
You can see the problem in attached file.
I have tried all UCCNC versions and reisntalled all including S.O.
Thanks.

1. Have you tried version 1.2038? It has a workaroud for a Windows/OpenGL problem.
2. I found some infos on this page. Maybe, you should try a BIOS update.
3. While toolpath is displayed wrong, is the program usable? I mean, when you click a button, does it react immediately?

Hi, thanks dezsoe.
I updated BIOS to the lastest version, reinstalled video drivers to the lastest version from SIS page and installed UCCNC version 1.2038. I have the same problem.
The progran is usable, all is working except 3D toolpaht viewer.

The computer is an IBM Lenovo ThinkCentre E50 8773-78G

Thanks.

I remember this same problem a customer reported to us earlier.
I think it was the same SIS graphics card model you have.
We debugged the issue that time and the problem was an OpenGL function not working on this card.
If I recall it was a function about Vetrtex buffers handling and I clearly remember that the card falsely reported some of it's capabilities,
I mean it reported capabilities which it was not capable of doing, so we could not resolve this issue with this card unfortunately.
So, this is basicly a bug in the OpenGL implementation on the card which we can't resolve.

My only advice can be to try to install another graphics card into the computer. If it has a AGP or PCI or PCI-e slot then you should be able to install another graphics card.
I do not recall any other cards than SIS having this kind of issue.
