  on 7i96 where should I wire the in position signal output and alarm signal output from the 2HSS86 Hybrid Servo Driver 

Yes, thank you! I should have come back here to report this as solved.

Even after waiting for a few days, upgrading LinuxCNC via the package manager still kept us on QtPlasmaC version ending in 84. Not sure what's up with the buildbot. So I set up a Debian VM here and built a deb from source to install on cutnweld's table. The QtPlasmaC version now ends with 88 and the pause issue is resolved. Thanks again for an awesome plasma control interface.

Following up, how did this go? Is the issue solved?

All are still usable and functional, all can still be downloaded, and all can run machines just fine, except EtherNET Mesa cards.

You can download and install ANY distro that is derivative of Debian and install LinuxCNC on it, from the latest Debian Pup, to several other "lite" distros that i would not consider lite at all.
Almost all of them will work in Live mode, so download, boot, test, and if you like it install it and LinuxCNC with:

Have a look at my ethercat xml for those drives, as I have nothing in the SyncManager 0 and 1 idx.
I did have an xml reading the drive digital inputs, which I'm sure was in the 2 and 3 idx, but I'm not sure where I saved it, and I've still not got as far as adding them to my current test setup.

You probably want to start simpler with just the enabling/motion

Strange, LibreOffice is excluded from the Debian Live-build ISO we create
github.com/LinuxCNC/linuxcnc-live-build/...e-lists/desktop.list
I don't know of any games installed.

Could you point out where these files are in linuxcnc or how you have come across them?

You can do as follows:
1. Download the Debian 13 installer.
2. During installation, deselect all window managers so that the system installs in text mode.
3. Do apt install xfce4-desktop linux-image-rt-amd64 linuxcnc (I'm writing from memory, maybe it needs to be done a little differently).
The system installed in this way will fit on an 8 GB disk.
It won't be comfortable to use, but LinuxCNC will work properly.

Notice the error window in the attached screenshot where I'm trying to run a subroutine from an external file.
It looks like a error created when extracting the subroutine name from the .ngc file that contains it, the first character of the subroutine is not any character that I recognize.  This code exists in General LinuxCNC Questions as part of pocketing program and
the .png file there was made on linuxcnc12.04 LTS.  The window overlapping linuxcnc shows the Debian kernel being used.
 

Is there a super-minimal LinuxCNC installation available? When I install the Debian-LinuxCNC ISO, all sorts of programs—such as LibreOffice, games, multimedia apps, etc.—get installed along with it. Isn't there an OS version that installs truly only the bare essentials? No one needs LibreOffice, games, or anything like that on the machine.
Thanks,
Hans.

Hi New guy here...

I am trying to get a 3 axis mill up and running. I am using three CL3 57E drivers for the axis(es) and have a A6 750w Servo motor for the spindle. 

Debian is up and working and Ethercat is installed. The cia402 is also integrated. Everything boots and looks good. I am running Linuxcnc 2.9.10.

UI is qt_dragon. Slaves are all there and go over to OP when linuxcnc starts... There are no errors other than a 5000 ns time out for the CL3 57Es no time out error for the A6 though? The Stepper motors do not energize... No buzzing, nothing and can be moved by hand. 

Button for the coolant work in the UI but the motors will not (just the CL3 57Es) activate and move. I don't know if I have missed something... I have spent the last 3 days searching the forum looking for answers and trying different things. It would be great if you guys could take a look at my config  files and let me know what I missed.

Thanks 
   

You might do a simple output voltage check with no load to make sure the issue is with the 7I76U card

All  step/dir outputs should measure very close to 5V or 0V. nay on between voltages suggest a damaged
output driver chip

Mesa can repair the card for a nominal charge but shipping will add up.

I have used the Teknic software and run an auto tune and it helped but the problem still exits.

I havent changed the step input resolution settings(which is 3200 steps/rev) because other folks have no problem nor should I. I can see a tuning change being needed per machine but not a reconfig of input vs resolution.

Thanks PCW;
Would it be more cost effective to replace the board or have it repaired?

Kind Regards,

I have an ATI graphics chip built into a Compaq presario, It is also called an ATI radeon 200 express graphics adaptor. If I was running Ubuntu 24.04 I would have to load the AMD graphics open source driver to get it working at all. Using the pre-empt kernel from the 2.9.10 released ISO it works fine and runs the latency histogram fine . I suspect a deep seated bug in the open source driver or the hardware itself which is one reason I'm going to Debian instead of Ubuntu.
