Problems with new computer

I built a new computer just for linuxCNC. I had it working on an old PC, but the latency times were really bad and it took forever just to boot up. This is my new build:

Gigabyte E350N motherboard
Gskill ripjaws 4GB 1600 MHz CL7
Intel 32GB SSD with LinuxCNC installed

Being that I had it running on the other machine I thought that this would be easy to get going. I verified that the parallel port is at 0x378 IRQ=5 and in stepconf I entered in the correct address. This is the error that I get when running my machine profile.

Any help is greatly appreciated.

Perhaps an Opengl problem.

Does glxgears run?

Have you tried running linuxcnc with the mini or tklinuxcnc interface?

Hi

There are problems with the drivers for the video chip on this board under 10.04

linuxcnc.org/dapper/emc2/emc2/index.php/...0-and-gigabyte-e350n

You don't say what your latency results were. If you do a test you may or may not have problems with glxgears (it does not load as much as axis).

Do what Rick suggests re alternative Guis, which should confirm it a driver GLX problem

The best solution would be to install 12.04 and then use Sebs 3.4.55-rtai debs.
The driver support is much improved in 12.04

highlab.com/~seb/linuxcnc/rtai-for-3.4-prerelease/

regards

I was getting latency times of about 4000 static and 6200 under moderate to heavy loading and computational tasking. I will give the drivers a try per that thread that you linked then I will post back here. Thanks for the help.

I tried the work around listed on the help page by entering:

sudo apt-get install libgl1-mesa-swx11

Then I restarted the machine and received the same error as before. Then I tried the driver install that was listed in the other thread and installed the AMD 12.10 driver per the install instructions. After I uninstalled the old ATI driver I restarted the computer and had the "low graphics mode" and I selected "repair" and "load default (generic) Xorg". Then I installed the recommended AMD driver 12.10. At this point I restarted the computer and got the "low graphics mode" so something must not have gone right during the install. I did some research and re-installed fglrx per instructions on ubuntu.org and this allowed the computer to start up normally without any errors, but I still get the same error when running the machine profile. I tried to create a new profile using stepconf, and that one failed as well and never started up.

I feel like I have tried so many things to get this working that I must be messing up more as I go along changing things. With that I decided to upgrade to 12.04 and try 3.4.55. Good news is I got drivers for everything and now my speakers work at least so I can watch youtube how to videos. Small victories I guess.

Here is what I did in the order that I did it:

I did the complete 12.04 upgrade
Downloaded the 3.4.55 files from here: highlab.com/~seb/linuxcnc/rtai-for-3.4-prerelease/
I installed the source file then the manual, then header fies and doc file.
Neither image file would install, one just wold not compile, the other said there was a dependency issue.

So figured I would give installing linuxCNC a try and it did not work for the following reason:

The following packages have unmet dependencies:
linuxcnc : Depends: python (< 2.7) but 2.7.3-0ubuntu2.2 is to be installed
Depends: python2.6-tk but it is not installable
Depends: python2.6-imaging but it is not installable
Recommends: hostmot2-firmware but it is not installable
E: Unable to correct problems, you have held broken packages.

So first I installed python 2.7.3 and then installed 2.7.3-0ubuntu2.2 and tried to install linuxCNC again. Same exact error. What am I doing wrong here?

Have you tried a non-graphical GUI? It doesn't seem to be an option in Stepconf, but it is a simple change to the INI file:
www.linuxcnc.org/docs/html/config/ini_co...ub_display_section_a

Try changing "[DISPLAY] DISPLAY = axis" to "[DISPLAY] DISPLAY = tklinuxcnc"

I have another SSD that I am not using so I think that I am going to do a fresh install and try this too. Thanks for the help.

I did a fresh install on the other SSD of 10.04 and did the above fix for the display in tht INI file and it worked like a champ. I still need to run latency tests and setup my machine configuration, buy I got my test motor turning. Thanks for all the help.
