Sure! Inside linuxcnc - or better said: in src/emc/nml_intf

My app uses nml-interface to interface backend of linuxcnc. I tried to follow 
axis, so I guess, I interface the nml-channels of task-manager.
Of cause, I use shared-memory side of nml, no network at all.

My test-scenario is start axis as usual from linuxcnc (which starts the 
backend as defined in ini-file) and then start my app from eclipse-ide. 
There I can debug my app and have all I need at my fingertips.
For the C--stub I use gvim and run gcc from commandline. Additionally I have 
some helpers that check nml-layer for changes ...

So my intention for jogging was, to use axis for jogging and my app as 
visualizer. This way I developed the rest of the app.
But that does not to work with jogging.
Or at least, I don't know how to make it work.
>From what I found in nml-layer I could change my app to execute jog-commands, 
but not show, what's going on.

What the heck is it?

And obviously I don't have one. I do have a handheld that I think works 
with the Mach that came with a 6040 mill but its never been plugged in.  
Doesn't have a real jog dial so its just something to be tossed AFAIAC.

Yes, but Wheezy is too old.

Do you have an xhc_wh04b-6 ? If not, then ignore it. If you do, stop
using Wheezy.

[Emc-developers] just noticed this on my wheezy box

[Gene Heskett]

Greetings all;

fyi, master build.

gcc: fatal error: no input files
compilation terminated.
expr: syntax error
gcc version  too old: skipping hal/user_comps/xhc-whb04b-6

gcc is uptodate, for wheezy.

Cheers, Gene Heskett

[Emc-developers] startup anomaly on OLD LinuxCNC

[Jon Elson]

Yes, I KNOW, this is a REALLY old version, but just thought 
I'd report it.


I'm running LinuxCNC 2.5.4 on my Bridgeport mill.  I just 
used it a couple days ago, everything worked
fine.  I started it up today, homed, and forgot to load the 
toolpath, and pressed R with the LinuxCNC
toolpath still loaded.  I immediately noticed it was heading 
for the wrong place and hit esc to abort it.
I then loaded the correct .ngc file, and when I pressed R, 
it again headed toward (0,0).
I reloaded the toolpath several times, getting the same 
response from that path and another old toolpath I tried.


Finally, I exited LinuxCNC and restarted, homed, loaded the 
toolpath and all was fine.
I believe I have experienced something like this behavior 
twice before, and never was able to put my finger on what 
was wrong.


I am using the Axis GUI.

Yes, someday I will update this system, but it does all I 
need right now, I don't do any LinuxCNC development on it, 
just cut metal.


Thanks for any comments,

Jon

Where are you looking? Inside Linuxcnc? Or in some kind of servo driver?
