I feel your pain somewhat, but I've worked through many of the difficulties. When you run the live CD (I used the latest Ubuntu 10.04), the first time you try to run the sim AXIS, it asks if you'd like to copy the files to your home directory. I answered YES. It makes a copy of all the EMC2 stuff in your home directory, which is:
/home/ubuntu When you try to run a program, there are two red buttons on the left. The leftmost is the ESTOP, and you must click it to get it out (out of ESTOP). The next one is the power button, and it needs to be clicked to push it in, but it doesn't look much different when it's in than when it's out. Then you try to run the program that is loaded by default, and you get the error you cited. I don't know the exact phrase, but your paraphrase is accurate. At this point click on "MACHINE" then a pull down menu gives you access to "Homing" then you can click on Home All. EMC2 will do some fancy stuff, and then let you run a program. The programs in /home/ubuntu/emc2/nc_files/examples (perhaps there's another level I've missed) are owned by root, who you aren't since you are ubuntu. The solution is to open a terminal window and type cd /home/ubuntu then type : ls -l to see if anything is owned by root. If it is, then type sudo chown ubuntu:ubuntu * Forgive me if you are more advanced than my instructions convey, but sometimes the extra stuff may help. The 'sudo' allows you to act as root. The 'chown' says to change the owner of files or directories. the first ubuntu is the new owner, the second ubuntu is the new group. Don't know if the second one is needed, but so far it hasn't hurt me. The star says to change every file or folder you find. If this isn't the case, perhaps someone else will correct me. Now we need to go to the next directory: cd emc2 ls -l If there's anything that needs ownership change, change it. If not, let's go on. The next directory should show in the listing in case I get the order wrong, or leave a level out since I'm not booted up into EMC2 ubuntu (you see I'm running Linux Mint for EMAIL purposes and all non EMC2 stuff because ubuntu thinks I don't deserve write access to my other hard drives.) I believe from EMC2 there are two options, the one in which the configuration files are kept, and nc_files. If your mileage is like mine, you may have to edit axis.ini, and (at least in the simulator) make EMC2 believe it has and enormous Z-axis to handle programs. The axis positive and negative limits are near the end of the file, and I usually have trouble with going beyond the Z axis limit. Again if this is owned by root, you will need to change owners. If you don't have security issues, so you don't need this PC protected by passwords, and you have already installed EMC2 ubuntu, then you may be able to get rid of your password by opening a terminal. Click through: Applications-->Accessories-->Terminal Then to become root type: sudo su Then to delete your password type: passwd --delete ubuntu or... instead of 'ubuntu', whoever you chose to be during the installation. If you want a password, but want to be logged in automatically when ubuntu starts, then delete your password (as shown above) then close the terminal. Then click on: System-->Administration--> Users and Groups On the left click on the user you are just to highlight it. Then on the right, password should say 'none'. Click on 'Change' to the right of none. Then you can enter a new password, and check the box that says 'Don't ask for password on logon'. Grace to you in this matter, cogoman On 08/08/2011 08:14 AM, charles green wrote: ubu8 and ubu10 + emc2 installs both provide the Axis gui errors, "cant do anything without homing" for any mdi command following the machine completing the homing sequence.? is there a way to get an up to date live cd with relevant patches and current bug fixes, or is the distribution only intended to be a 'let's see what happens' type of thing for fluent command line linux personnel? ------------------------------------------------------------------------------ uberSVN's rich system and user administration capabilities and model configuration take the hassle out of deploying and managing Subversion and the tools developers use with it.
