So i did some remastering to the live cd of linuxcnc 2.5, also made a lite version using Xfce4, this version has only the bare minimum to run LCNC.. I added the Linuxcnc tux logo to the installer, I also modified the plymouth splash to use the Tux LinuxCNC logo on boot. For a live .iso only, i disabled the installer and configured Syslinux to boot straight into the OS, no menu's. Im in the process of writing a gui that only uses the frame buffer, and will eliminate Xorg completely. I'm not sure what i will gain here but when i run the Rtai module kernel latency test in Xfce4 or Gnome version i see a 2000ns difference in the max latency when compared to running it in CLI. Im not positive how this correlates between the latency test shipped with linuxcnc hopefully someone on here can chime in with that, or ill take a look at the source code and figure it out. I'll take some screenshots later this afternoon. the Xfce4 iso is only 250mb. Also only ships with the En language package, though adding the locale package's back in is trivial and only adds about 20Mb of additional space.
If your wondering what the point of this is, I want the OS to feel as if, its only linuxcnc for the machine's i design. I have been unable to duplicate the RTAI latency i can get with the shipped package from linuxcnc on any other distro so i decided to stick with Ubuntu. I built the lite version using Ubuntu-mini-remix a great starting .iso for those interested. I will be using a Compact Flash drive on the controllers with my machine. It will load the .iso live into ram on boot every time this makes updating a breeze i can remotely send a new .iso if bug fixes or improvements are made to the os and linuxcnc itself. I'll leave this open for comments or criticism. Thanks Gabe ------------------------------------------------------------------------------ Don't let slow site performance ruin your business.
