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

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?
