ubuntu 10.04 Lcnc2.7 JA8 custom kins was created by bkt
is possible to install some version of Joint_Axes on ubuntu 10.04 and Lcnc 2.7? Where can download these version?

I get JA8 from git but I doubt if I can successfully install it on a PC with Ubuntu 10.04 and 07.02 LCNC ..... I fear jumps out some lack of dependencies .

Tanks for suggest. (for now I want to keep ubuntu10.04)

It should be no problem at all to compile JA8 on 10.04 (or, to be more accurate, no more trouble than compiling any other version).

Just try it, and work through the problems one by one.

You can try the following commands to check the build dependencies

$ cd debian
$ ./configure
$ cd ..
$ dpkg-checkbuilddeps

That will give a list of packages which is almost ready for a mammoth "sudo apt-get install" command. Some editing is needed in cases where it gives options or a minimum version number.

ok ok ...... in my case:
Code:
.../home/.../linuxcnc_JA8/script/rip-environment linuxcnc /......./config/n/n.ini

but I return an error

and in print.txt
Code:

Why these? .....

To run a self-compiled version of LinuxCNC you typically need to open a terminal and run
Code:
. linuxnc-dev/scripts/rip-environment
(which really is dot space at the beginning) to set up that particular terminal session to use your version, then start linuxcnc from the command line with
Code:
linuxcnc

To make a shortcut run the new version you have to actually install during the compile process. You can do this with ./configure --prefix=/usr but it is probably best to try it out without messing up the installed version first.

In a terminal...
Code:
cd /home/myInstallationFolder/scripts . rip-environment linuxcnc /config/myconfigfolder/myconfig.ini

Isn't the same? .... I try in these way and I get the error ...... tomorrow I try in these :

. linuxnc-dev/scripts/rip-environment


For controll .....you put the link to check the version JA8 correct ? ..... I checked and mine is full of gitignore ..... I would have installed a fake .

ok ..... whit complete command in a terminal :
Code:
cd myinstallationfolder-of-JA8 . config/rip-environment linuxcnc
start JA8 and I can choose my config from Lcnc-JA8 menù .... the script reconfigure ini and hal file or, as in my case, bring the ini and hal file modify by hand .... this is ok.

But I use custom deltakins kinematics (is different from tripodkins, use 2 side of triangle and the length of 2 link ... than I add other 2 axis) need to compile for JA8 version. Mine is .c file ..... I think I can compile it with gcc but in whitch directory of JA8?

Once you have run the . rip-environment script then "sudo halcompile --install yourkins.c" will install the kinematics in the correct place.

Alternatively you can put your kinematics with the others in src/emc/kinematics and edit the Makefile to add your kinematics to the normal compile.

git.linuxcnc.org/gitweb?p=linuxcnc.git;a...bc48665a300515b#l888

If you search for "trivkins" you will find 5 entries, just duplicate those lines for your kinematics.

It is likely that the "halcompile" method is more suitable for your situation.

ok ok stupid question ..... using
Code:
sudo nautilus
I copy compiled version of my custom deltakins from Lcnc 2.7 rtai/module to myistallationfolder-of-ja8/rtlib and all works ....

Bu I see that I have the original issue .... external jog not jogging in world mode .... axis +/+ button jog works in all mode .... I try to set teleop mode after all axis are homed but this not solve.

Than the terminal show me these first and than run correctly my config
Code:
waiting for s.joints waiting for s.joints waiting for s.joints waiting for s.joints waiting for s.joints waiting for s.joints waiting for s.joints waiting for s.joints

but there is not joint.s in my conf in any place. Not at all.

These a piece of hal file for jog .... net joint-select-a => joint.0.jog-enable # <= hm2_5i25.0.7i77.0.0.input-16 ...obviuusly these net joint-select-a is connect with hm2.....16pin in an other parts of file ....

[quote="k-1" post=65414but there is not joint.s in my conf in any place. Not at all.[/quote]

The "s" here is a variable that holds the status data for the LinuxCNC system. There is never an "s" axis in LinuxCNC.

What are you external-jogging with? Buttons or MPG?
