Thanks for paying attention rodw. I'll make a new install and tell you the results.



Sorry you wasted your time. In my original post, I did say
If you are running a Mesa ethernet card you will need to install the preemptive kernal befiore installing Master.

No problem.I have learned from your post and andy's post.Also, I have learned how to customize the installation (minimal display server, minimal desktop manager, minimal window manager, grub themes, apt sources.list, kernel install and isolcpus). Thank you for sharing your time.

Hello again. I made a new install using the wheezy image. I installed the master branch. The current Lcnc version is 2.8.0 . Where to start, now?

Just start the config:

linuxcnc-dev/configs/sim/gmoccapy/gmoccapy-JA/Gantry/gantry_mm.ini

Do not forget to start from terminal and do a rip-environment befor starting the config.

Than change the sim config to fit your needs.

My plan is to get to gmoccapy but have started playing in axis as a starting point. I have read that is is the best for troubleshooting. It has a window you can open up to watch all of the inputs and outputs as LEDs on the screen which is very useful. So start by running stepconf and set up a system and then see if anything moves. It will create a config.

I found there is 4 things to do in Axis before you can run any gcode.
1. Turn off the estop
2. Turn on the machine
3. Home all
4. Touch Off

Then you can press start and it will run.

As I don't have limit switches in place quite yet, I had to change some of the homing settings

Hi rodw. I think I have problems with master install. I'm lost here. here you are what I did:
I used Linuxcnc live Debian image. which has the 2.7 Lcnc version.
I disabled the Lcnc and Lcnc-dev from synaptic package manager.
I got the devlopment version:
git clone git://git.linuxcnc.org/git/linuxcnc.git linuxcnc-dev
cd src
./autogen.sh
./configure --with-realtime=/usr/realtime-3.4-9-rtai-686-pae
make

At this point I see the make repeats with no stops.
Can you tell me what to do, please?

I believe the trouble shooting tools you are referring to is Halshow and or Halmeter. Both of which are accessible in Gmoccapy, or any other Linuxcnc UI. They can actually be run separately independently of any ui in Linuxcnc (Halscope as well). They only need halrun running at a minimum.

In a terminal four useful commands are:

halcmd loadusr halmeter
halcmd loadusr halshow
halcmd loadusr halscope
and
halcmd loadusr sim_pin ...

(sim_pin needs a list of pins / parameters / signals? and allows you to set the values, very good for exercising a system)

rather than type "halcmd" all the time you can join a running HAL session with
halcmd -kf
and then just type HAL commands (show, setp, sets, net, del loadrt, addf, etc etc)

But in Gmoccapy there are buttons to open those windows at the bottom of the Maintenance screen.
