Hah!, but no! It's incorrect when I use the keyboard jog. Cursor key left / right should move the X-axis. (It did before and does when I restore my original setup.
I'll sort it out next weekend. Thanks.

Hi, Fern.
I can't seem to get this to work. I started again and had AXIS running properly. Here's what I did next:

- Extract NativeCAM download to my home folder. This will install a folder NativeCAM-master.
- For some reason the unzip creates ~/NativeCAM-master/NativeCAM-master/. I moved the inner one up to ~/ to keep the file paths shorter.
- Go to ~/NativeCAM-master and double-click on ncam.py. It will install the NativeCAM application in standalone mode and open it up.
- Open a Terminal window.
cd ~/NativeCAM-master
sudo ./ncam.py -i ~/PathTo/MyMillIniFileName.ini -c mill
- Start AXIS pointing it to my ia-mill.ini.

Hi, Fern.
I can't seem to get this to work. I started again and had AXIS running properly. Here's what I did next:

- Extract NativeCAM download to my home folder. This will install a folder NativeCAM-master.

DO NOT EXTRACT...
Instead open a terminal in ~
and use : git clone github.com/FernV/NativeCAM.git

- For some reason the unzip creates ~/NativeCAM-master/NativeCAM-master/. I moved the inner one up to ~/ to keep the file paths shorter.
- Go to ~/NativeCAM-master and double-click on ncam.py. It will install the NativeCAM application in standalone mode and open it up.
- Open a Terminal window.
cd ~/NativeCAM-master
sudo ./ncam.py -i ~/PathTo/MyMillIniFileName.ini -c mill

NEVER USE 'sudo' with ncam.py, it will create directories where you only have read permissions

Erase ~/NativeCAM-master and everything you created with those commands and follow the instructions.
All in a normal user terminal in your home directory

1- clone with : git clone github.com/FernV/NativeCAM.git
2- cd NativeCAM
3- ./ncam.py to make sure it runs stand alone and no package is missing, you can delete ~/nativecam directory later
4- close nativecam

I RECOMMEND THAT YOU NOW RUN : sudo ./nondeb_setup.py c
THEN ISSUE THIS COMMAND : sudo ./nondeb_setup.py

Try : linuxcnc /home/cnc1/NativeCAM/configs/sim/axis/ncam_demo/mill.ini
This will start linuxcnc with nativecam embedded

When satisfied, convert your inifile with this command from ~/NativeCAM directory :
./ncam.py -i /home/cnc1/linuxcnc/configs/ia-mill/ia-mill.ini
A backup ia-mill.ini.bak will be created.

Run linuxcnc normally using : linuxcnc /home/cnc1/linuxcnc/configs/ia-mill/ia-mill.ini

Thank you very much for your help. I've followed your instructions exactly and am almost there.

This starts AXIS but without the NativeCAM panel.

Can you spot my error?

Thanks again.

From '/home/cnc1/linuxcnc/configs/ia-mill/ncam' delete 'cfg', 'graphics' and 'lib' subdirs/links
Sometimes it fails to delete old stuff, I have to find out why but the cause may be you started ./ncam.py with a 'sudo' command before.

Restart lcnc with : linuxcnc /home/cnc1/linuxcnc/configs/ia-mill/ia-mill.ini

From '/home/cnc1/linuxcnc/configs/ia-mill/ncam' delete 'cfg', 'graphics' and 'lib' subdirs/links

Done + a few more that I found.

linuxcnc /home/cnc1/linuxcnc/configs/ia-mill/ia-mill.ini

NativeCAM error popup:
Error creating link : /home/cnc1/NativeCAM/examples/mill -> /home/cnc1/linuxcnc/configs/ia-mill/ncam/catalogs/mill/projects/examples

followed by another:
Error creating link : /home/cnc1/NativeCAM/examples/plasma -> /home/cnc1/linuxcnc/configs/ia-mill/ncam/catalogs/plasma/projects/examples

Then AXIS opens without NativeCAM.

Your errors : Code : [Errno 13] Permission denied
are the result from running : 'sudo ./ncam.py'

The directory : /home/cnc1/linuxcnc/configs/ia-mill/ncam
is owned by the superuser
You will have to delete it with : sudo rmdir /home/cnc1/linuxcnc/configs/ia-mill/ncam

You should not have any problems with /home/cnc1/NativeCAM directory

Then restart : linuxcnc /home/cnc1/linuxcnc/configs/ia-mill/ia-mill.ini

Hi, Fern.
I deleted all the NativeCAM folders and files, installed again as per your instructions above and it works correctly now. Thank you for your time and your excellent application.

Replied by gmouer on topic Ncam crashing after taking updates
Hi Fern,

I have a Ncam system that has been working flawlessly for quite some time. I have NOT installed the recent updates that you released in the last month as yet.

Today, I took updates on the computer (op system and lcnc)and now Ncam/Lcnc crashes on startup. I am getting some glade errors related to NativeCam as shown in the attached screenshot. (Ignore the Hidcomp errors, I got those under control). The updates today included a update for Linuxcnc to 2.7.9 , before today the system was operating under 2.7.8 which ran fine.

Hopefully you can help me out.
