All the spindle control stuff would be on TB3

(the SSR outputs for FOR and REV and PWM for the speed control)

Those are unused resources (for sserial expansion) and not relevant to
configuration (unless you want to repurpose those I/O pins)

current latest download of LinuxCNC V2.9.8 will not install GRUB on several PC's

Category: Installing LinuxCNC

Also be aware that Trixie no longer uses /etc/apt/sources.list.d
Instead it uses the new deb822 format and places its sources in /etc/apt/sources.list.d
And as you said, for a DVD install, the source files will be configured to look on the ISO, not at the Debian mirrors

But the default Debian download on their home page is the netinst ISO, same as LinuxCNC. You need to follow the link to other downloads and select the complete installation image to install on an offline PC. The Linuxcnc 2.8 installer on Debian 10 used the same installer so nothing has changed for many years.

I found out the hard way this week that the Debian installer deletes packages that are not used at run time. eg if you go to the trouble of deploying LinuxCNC built from source in the installer, (eg a 2.10pre version), you must reinstall the dependencies if you want to rebuild the image.  The build time dependendcies are removed before the ISO is created.There are settings that are meant to prevent this but they did not work for me.

The days of Debian fitting on a single DVD must be over. I thought they maxed out at 4.7 gb. The image I built  yesterday came in at 5.15 gb.

I'm off to buy a CPU cooler today. Debian 12/13 do not manage heat well or my 20 core Lenovo i7 is underspec in the CPU cooling department as it regularly overheats and hangs during video rendering or compiling. Hopefully I can shoehorn one in in this small desktop case!

What AI thinks of Flex GUI

Category: Flex GUI

Here is what I think about FlexGUI: It's freaking awesome! I'm really enjoying the interface; it's a total game-changer for building my custom LinuxCNC GUI. Thank you for all the hard work you put into it.

One thing I'm missing is a live preview/sync in the G-code editor.

Are there plans to implement 'Scroll-to-Line' or 'Active Line Highlighting' during a program run? Or is there a technical limitation in the current widget architecture that prevents this?

Thanks.

I've finally gotten a little time to work on this again!

I'm still planning to use the MR-J3-70A drives, which I have already. What is the current state of support for the copper network drives?

That would be the 7I96S manual that lists the terminal block pins for
step/dir, analog out. encoder  and SSR channels.

These are also listed by mesaflash's  readhmid command

Mon interface est une carte Mesa qui prescrit de ne pas activer le WiFi pour des raisons de temps réel. Alors, j'ai respecté cette consigne sans avoir osé tester si cela était vraiment utile.
Depuis ma demande initiale, j'ai trouvé comment faire en sorte que le module DS1307 s'intègre bien au système en rédigeant un petit service qui se met en route durant le boot.
