The only time you have to deal with degrees is joint or axis positions from/to EMC. They are degrees because gcode is degrees, I guess.

The important thing is you need to be running a brand NEW version of EMC2. I think only the latest 2.2.8 EMC2 update will have this in it. Otherwise, you'd need to update from CVS source.

[Emc-users] Ubunto Installation Problems
I'm trying to boot from the ubunto 8.04 live cd with EMC. I checked the md5sum and it is correct. I get a ubunto prompt, and it tries to boot, but then I get the message BusyBox v1.1.3 Debian 1:1.1.3-5 ubuntu 12) Built in Shell (ash) enter help for a list of commands (initramfs). Same thing happens if I try to check the cd for defects. Wonder what I'm supposed to do now?

Re: [Emc-users] Ubunto Installation Problems
When that happens, it indicates that the installer is not able to read the cd. I'm not aware of any troubleshooting information that it is useful to gather at that point, or any specific solutions to this problem besides trying a new CD burn if you haven't already. You might try downloading the official ubuntu 8.04 cdrom image from ubuntu.com. If the installation completes with that cd image, you can then go on the network and add the emc2 packages using the emc2-install.sh method described on our website: http://www.linuxcnc.org/content/view/21/4/lang,en/ On the other hand, if you get the *same* error when using an official ubuntu 8.04 cd image, then you can ask for help on websites like ubuntuforums.org or search for help on help.ubuntu.com.

Re: [Emc-users] Ubunto Installation Problems
That usually happens if it can't detect your harddrive controller or disk. Not much you can do about it thought, maybe try the 6.06 LiveCD or the plain Ubuntu 8.04 disk, then follow the instructions from www.linuxcnc.org to install emc2 on it.

Re: [Emc-users] Ubunto Installation Problems
When I first began with EMC over a year ago (6.06 version of Ubuntu), I ran into issues getting ubuntu to load up. I was using a dumpster desktop. I eventually succeeded using the method Jeff suggests. One of the things that hampered me was too little RAM. Make sure you have at a minimum 256 or more. A recent build on a second machine to run the simulator on, I put all the RAM in that box to do the install, then dropped it back to the minimum ram it has now.

Re: [Emc-users] Ubunto Installation Problems
Sometime it works to change out the CD drive. I had much better luck with 8.04 live than I had trying to install the non-rt Ubuntu. MD5sums were always OK. YMMV Good Luck.

Re: [Emc-users] NetMos 9805 PCI Parallel Port Card Problem (I/O Ports disabled)
Thank you very much. The differences between this output and output on my computer are only in addresses. (:00:10.0 and I/O port addresses). On my computer I/O port address, if I can good remember, are something like a400, a000, d400, d000, ., 9800 etc, but all I/O ports are disabled. I did not know, that this addresses are so important. I will try to do tomorrow, what you have suggested and I will get real output of lspci. Anyway, thank you very much. Your information seems very helpful. I will be able to test it tomorrow and inform you about results.
