hello,

i did ethercat master driver reinstallation from generic to natural which is on the chipset on the board for some performance configuration for time period reduction... everything works well till I do not switch power of slave 24V mains off... after that ethercat master service is still active but bus is death... I have to do 
for restart the ethercat bus ... how to do it automaticly or am I missing something?

regards...

Last night I had the same problem on Raspy 5,
I must have solved it with --fix-missing
as it tells you at the bottom in the terminal
hi

My suggestion is to give up ecat-io and look for other solutions, such as mesa card or fpga or arduino (I don't know how fast they are

But I like ethercat
But it  adds additional expense and complexity.
I am tempted to get one of these to play with it. Once I finish the mesa control box I am working on...

Thanks man, sorry about the frustration.....

Very sorry. I don't have write access to the website so depend on others who I give the ISO to.
Please try my ISO in Google drive, I know it works as I have tested it on real hardware.

I used the latest I could find

Just to be on the same page
Did you use this one:
 

from here:
linuxcnc.org/downloads/

Note, for the gcode to reload you need to switch to the 'AUTO' mode screen in gmoccapy.

Seems likeI lost the hashbang in the first line of the python code in my last post.
I just fixed that, so copy/paste the fixtd python code above and try again.

The kinematic compensates for tool length.

Are you sure you have connected the required pins:

Hello,
I think I'm making a mistake somewhere
The file.txt file is in the config folder, but I think it cannot find this file.

./python/file-check.py: 1: import: not found
./python/file-check.py: 2: import: not found
./python/file-check.py: 3: import: not found

wow, that looks really professional, you can tell it's not the first time you've done it.

I wouldn't know what to say about it either, you're doing really well!

There are easier ways to start playing around with kinematics. I would suggest to have a look at 'millturn', also have a look at the linked paper:

forum.linuxcnc.org/38-general-linuxcnc-q...atic-mechanis#306700

[edit]
Just for completness, 'trivkins.c' uses functions in 'kins_util.c':

 

But again, unless you know your way around with C I would strongly recommend using the .comp method with 'halcompile --install  your_path/your_kinematic.comp' as in the 'millturn' example pointed out in the link above.

Hello, I am a beginner trying to learn LinuxCNC. Please note that not only that I am totally new to LinuxCNC, but I am also totally new to working with CNC machine, G code, and the C programming language, so please forgive me if I ask stupid questions. Since I don't have any lathe or mill that I can experiment with (without messing things up), I am playing with LinuxCNC on a virtual machine (Debian inside VirtualBox). I have successfully managed to build LinuxCNC using run-in-place method as instructed in this guide linuxcnc.org/docs/master/html/code/building-linuxcnc.html .

Right now, I want to understand how .c kinematics files work in LinuxCNC. So, as a first step, I did a little experiment by modifying the inverse kinematics function in trivkins.c (located at src/emc/kinematics/) as shown.

My understanding is that the inverse kinematics translates the position of the tool into joints variables, so by putting a negative sign in front of pos -> tran.x before passing that to identityKinematicsInverse function, I expect the machine to move in -x direction whenever I command the machine with G code to move in +x direction (like G0 X10). 

After I have modified trivkins.c, I compiled the file and rebuild LinuxCNC by going into /src and use  ./autogen.sh, then ./configure, and then make. 
However, as you can see in the photo attached   , when I open axis.ini config (which I believe it uses trivkins.c), the machine still do engraving in the +x direction. Nor did it go to X-10 when I command it with G X10.

I tried modifying trivkins.c in different ways, such as setting some directions to a constant, but I still experience the same result. So what did I do wrong here? Why I see no changes in AXIS after I modified the kinematics files. I am pretty sure the trivkins.c was compiled because when I deliberately put syntax error line in there, make threw an error

This is looking amazing!   I am impressed with how smooth that boomerang video looked!  Absolutely fantastic work my friend!  Thank you very very much for your hard work!
