Native cam help with ini.file/ subroutine_path was created by Dougefresh

I'm having a noob issue with controlling my cnc once native cam is intergrated. I can control my cnc from my original configuration file but when I try with native cam I cannot.

I'm thinking I have to copy over the ini. File from native cam to my original ini.file?

What linuxcnc version are you running?

Can you post your ini file?

Here is the readme of Ncam;

github.com/FernV/NativeCAM

go into terminal and issue this command from your home folder:

Code:

git clone https://github.com/FernV/NativeCAM ncam

When complete you will have a new folder named ncam in your home directory. Enter the directory and follow the read me for imbedded ncam into axis.

In your ini you have to edit your display section and also your paths sections. The relative bits are in asterisks in the sim .ini I copied and pasted here.

Warning: Spoiler!

NativeCAM for LinuxCNC - realtime CAM

This is reading for any installer but if you are a linuxcnc developper you should also read README-DEV

Clone or extract in a ~/sub-directory of your choice with read/write rights

Open a terminal window in the same directory

Make sure these files are executabbes : ncam.py uninstall-features (to restore the modified files after you delete the old version)

You need to install python-lxml if not allready installed, the command is : sudo apt-get install python-lxml

1. Simple usage - Stand alone mode

1.Copy then paste one of these commands :

for mill : ./ncam.py -iconfigs/sim/axis/ncam_demo/mill.ini ; ./ncam.py -iconfigs/sim/axis/ncam_demo/mill-mm.ini ;

for plasma : ./ncam.py -iconfigs/sim/axis/ncam_demo/plasma-2d.ini ; ./ncam.py -iconfigs/sim/axis/ncam_demo/plasma-2d-mm.ini ; ./ncam.py -iconfigs/sim/axis/ncam_demo/plasma.ini ; ./ncam.py -iconfigs/sim/axis/ncam_demo/plasma-mm.ini ;

However it is not meant to be usefull stand alone unless LinuxCNC was/is loaded with the right SUBROUTINE_PATH

2. Best way - Run embedded

1.Issue / copy then paste the following command

sudo python setup.py

This will create required links and modify files. You do not do this more than once except maybe after lcnc updates because it will replace the files and erase the link, until NativeCAM is integrated in the distribution To restore the system, simply issue the command : 'sudo python setup.py c'

2.Start LinuxCNC with one of these commands (copy/paste) :

for mill : (axis interface) linuxcnc configs/sim/axis/ncam_demo/mill.ini ; linuxcnc configs/sim/axis/ncam_demo/mill-mm.ini ;

(gmoccapy interface) linuxcnc configs/sim/gmoccapy/ncam_demo/mill.ini ; linuxcnc configs/sim/gmoccapy/ncam_demo/mill-mm.ini ;

for plasma : (axis interface) linuxcnc configs/sim/axis/ncam_demo/plasma-2d.ini ; linuxcnc configs/sim/axis/ncam_demo/plasma-2d-mm.ini ; linuxcnc configs/sim/axis/ncam_demo/plasma.ini ; linuxcnc configs/sim/axis/ncam_demo/plasma-mm.ini ;

(gmoccapy interface) linuxcnc configs/sim/gmoccapy/ncam_demo/plasma-2d.ini ; linuxcnc configs/sim/gmoccapy/ncam_demo/plasma-2d-mm.ini ; linuxcnc configs/sim/gmoccapy/ncam_demo/plasma.ini ; linuxcnc configs/sim/gmoccapy/ncam_demo/plasma-mm.ini ;

for lathe : (not supported yet) linuxcnc configs/sim/axis/ncam_demo/lathe.ini ;

3.Open a project in the examples directory

for mill : Basic spacer.xml ; Fun wheel demo.xml ;

for plasma : plasma test.xml ; plasma demo.xml ;

3. Tutorials

1.Use menu help->NativeCAM on YouTube

or follow this link

4. Translation

1.Under development

5. Setting-up your own file

Thanks cncnoob. I will try again tonight. Im still a little confused on how to modify the subroutine path. So you just copy the files from the native cam ini. To your my-mill ini. Created by linux cnc?

Maybe seeing your modified ini. File would help me to better understand.

Here is my ini for axis. Look for my path's and how they are modified from yours. Be sure to follow the readme I linked. The display section is where you really need for ncam to embed into axis.

Attachment not found

You must edit your ini file to reflect these changes. The ini that your machine uses to load linuxcnc.

I finally got ncam to load embedded when I start linux cnc. Im getting an g-code error when I try to load a work peice. Im positive I dont have a file in the right place...

Sounds like you don't have the paths correct for where ncam is located.

Send me an email and I'll respond with my number. I'll walk you through it.
