[Emc-users] Latency issue
Hello all, I'm new to this group and also to EMC. I have just succesfully installed Ubuntu 6.0.6 and EMC and updated it to 2.2 without problems. When I tried to configure EMC however, I was confronted to the latency issue (close to 100 uS) mentioned in the docuentation, related to MSI boards. My computer is a laptop Dell C610 Pentium III 1Ghz. I'm not sure what kind of board or chipset it uses but it looks like if I'm suffering exactely this issue, as when I run the latency test, the numbers are low (in the region of 10 uS) but aproximately every 64 seconds, it has a pick which tales latency up to close 100 uS as mentioned. I have followed the directions I got from linuxcnc.org page which includes replacing the binary module rtai_smi.ko and modify rtapi_conf, but when I tray to save this file with the changes done, I'm not permited to save it as it is read only and apparently, I have no permisions. Is someone there who can direct me on how to get arround this barrier?. May be the solution is simple, but I have to mention that I'm also new to Linux. Thanks in advance.

[Emc-users] Is updating EMC@ impossible without internet?
Hi, Updating emc2 seems impossible without an internet connection on the machine. Is this true? My trusty USB flash drive means I can transfer the files easily from another internet connected machine. I tried downloading and copying the 2.2.1 source files and there is no GCC compiler in the Ubuntu install so the install failed. I tried to get the build-essential turned on in Ubuntu but it seems to require an internet connection so that failed. So far the only way I have successfully updated emc2 is to wait for the Live CD and reinstall. Am I missing something or is this just the way it is? And, can a future Live CD include a gcc compiler?

Re: [Emc-users] Latency issue
On Linux, modifying system files requires the use of administrator (root) privileges. I would do an activity like this in the terminal window with sudo: sudo cp rtai_smp.ko /usr/realtime-2.6.15-magma/modules/rtai_smi.ko (assuming you have already changed to the directory where you compiled or downloaded rtai_smp.ko) I have updated the page http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?FixingDapperSMIIssues to give this instruction, so that hopefully the next person won't have the same problem.

Re: [Emc-users] Is updating EMC@ impossible without internet?
You need to copy the emc2 2.2.1 deb package. You can find it here: http://www.linuxcnc.org/emc2/dists/dapper/emc2.2/binary-i386/ Maybe if you try to install it (dpkg -i /path/to/emc2_2.2.1_i386.deb) it will tell you there are some dependencies missing. You should write those down, and write me an email with them. You can probably find the missing dependencies at http://packages.ubuntu.com/dapper/ Regards, Alex - Original Message - From: xtra209 [EMAIL PROTECTED] To: emc-users@lists.sourceforge.net Sent: Wednesday, November 14, 2007 4:05 PM Subject: [Emc-users] Is updating EMC@ impossible without internet?

apt supports offline operation with the --print-uris option. You can find various instructions on how to do this, though I have never tried it myself. e.g., http://olympus.het.brown.edu/cgi-bin/dwww?type=text/plainlocation=/usr/share/doc/apt-doc/offline.text.gz Jeff - This SF.net email is sponsored by: Splunk Inc.

True - Either to download packages, or CD images. So far the only way I have successfully updated emc2 is to wait for the Live CD and reinstall. Am I missing something or is this just the way it is? Reinstalling is the Microsoft way. In the world of Linux (and in particular, with Debian based distros) just wrong. And, can a future Live CD include a gcc compiler? I'm pretty sure we could fit JUST the gcc compiler on the CD, If you look on the unmodified Ubuntu CD, you *will* find gcc. What is missing from this modified emc2Live is most of the development tools one would normally expect. Indeed, in the early days of EMC CDs, Ray was always insistant on tools libraries being included. but to put all the delevoper files required to compile EMC2 on the CD definitely would not fit. Maybe somebody could bundle all these up and put them on a CD. I have the tools, scripts, and repository mirrors to do just such a task. Takes minutes to edit a package list and trigger a full build (which usually runs for 30 minutes or so). I think I actually know enough to do this one. (Gulp, have I just volunteered?) debmirror apt-ftparchive man pages will point you in the right direction. But DON'T look at the crazy way that emc2 repository tries to mimic a Debian/pool layout.. --- - This SF.net email is sponsored by: Splunk Inc. Still grepping through log files to find problems?

Re: [Emc-users] new 5 axis simulation
at build time, stuff in src/emc/usr_intf/axis/scripts/ gets copied to bin/ stripped of its .py extension and made executable. this is done in the Makefile, and for some odd reason each script has its own entry there. so, add 5axisbridgegui to the Makefile, or just rename the binary, or make a symbolic link to the actual script so you dont have to 'recompile' every time you change it. -fenn On Wed, 14 Nov 2007, Stuart Stevenson wrote: Gentlemen, I tried to copy the files to new file names so I could modify them.

Re: [Emc-users] Is updating EMC@ impossible without internet?
We've missed the easiest way to update an off line machine with 6.06 and I suspect later versions. Just download the deb, drag it onto the desktop and click on it. The system is smart enough to recognize a deb and start the package management stuff. Ray On Wed, 2007-11-14 at 16:36 +0200, Alex Joni wrote: You need to copy the emc2 2.2.1 deb package.

I first clicked on the file after putting it in my home folder.

Then I did a sudo dpkg -i /path/to/emc2_2.2.1_i386.deb. All went well and the new emc2 is installed without a hitch! This is on an extra linux machine which I try things out on before risking my working machine. I think I'm ready to try it on the real deal.
