Do you have a link? I have no idea what that is (it isn't a 7i92) but I do see a little "LinuxCNC" logo so possibly it is a clone.
Except to be a clone there would need to be an FPGA chip in that big pad array in the middle.

The "real" 7i92 is here:
store.mesanet.com/index.php?route=produc...t_id=378&search=7i92
or here:
eusurplus.com/index.php?route=product/pr...t_id=168&search=7i92


Is it this one?

I would probably pay the extra for Mesa support and warranty.

Hi Andy,

many thanks for your support.
What do you think would be the best / cleanest way?
Update or new installation with the ISO?

By the way, for my DELL Optiplex 3060 this would be the "LinuxCNC 2.9.4 Debian 12 Bookworm PREEMPT-RT ISO" ?

Best regards
Jens

Hello,
Thank You for reading my post.Yes - the installation was on a formatted/clean HDD and the ISO-Image was OK. The only software I additionally use on the Machine is FreeCAD (as an App-image) to generate the g-code for my projects.
I attached a zip-file with my complete configuration.
My cnc is simple, so I did the following adjustments:
- I use a script for dynamic tool measurement. So I can use FreeCAD's g-code with different tools in a single project.
- I use a delay after starting the spindle
- I use a debounce for the probe
You will find these changes in the ini-file and hal-files. These changes does not affect the described Issue.
I’m afraid my post is in the wrong category. I should have chosen “qcvcp.” Because problem belongs to the display category.
Is it possible/necessary to change the category?
Thank you for your help


 

Beide Latenzzeiten sind schrecklich.

The first image is running a realtime kernel, but the jitter is larger than is really useful. (0,4 ms in a 0,025ms thread will not work )

The second image shows a system that is not even running a realtime kernel, so the jitter is huge, 10ms or more.

You should try installing the latest realtime kernel and see if things improve after reboot.
sudo apt-cache search linux-image-rt
will give you a list of available realtime kernels. Find the newest listed and then
sudo apt-get install linux-image-rt{rest of the name}

Alternatively you could tre a fresh install from the LinuxCNC ISO image.

Can you describe how the setup is failing?

One thing that may be wrong is that the "width" seems very large. This is the number of encoder counts each side of the tool slot that is considered properly aligned. Normally it would be at most tens of counts.

The "scale" is meant to be the number of encoder counts between pockets. If your system has 1 servo motor revolution per pocket then your scale is probably correct, but if one servo motor revolution is one carousel revolution then you should divide the encoder full rev counts by the number of pockets.

I am aware that "carousel" has grown to the point that it ought to have a dedicated manual section. (Or maybe there should be a section on toolchangers in general. It's a big subject)

I couldn't attach the SVG files either. But I have attached bitmap reviews so that folk can understand what GraphViz is. 

What's the GUI? It looks specialised.

Hello Chris,
sorry for the late reply,
After Problems with other Software I did a fresh installation a few weeks ago. With all updates the versions are: "QtDragon_hd Version 1.5 on Linuxcnc 2.9.7"
For creating g-codes I use FreeCAD as an APPImage on the same machine, so there is no other software installed on the Computer.

Any one using this card?
pleas help i bought one 
New in linux cnc 

Hallo Leute,

nachdem ich nach ständigen Fehlermeldungen beiden Rechner nun nochmal komplett neu aufgesetzt habe, funktioniert nun alles sauber und ohne Fehlermeldungen, jedoch ist die Latency sehr viel schlechter als vorher.

Da ich von der alten und neuen Installation jeweils ein Image gezogen hatte, kann ich hier (mit etwas Zeitlichem Aufwand) schön vergleichen.
Nun ist mir im Latency Test aufgefallen, dass die alte Konfig einen aktuelleren Kernel verwendet (6.3.0), die Neuinstallation jedoch den 6.1.0. Nun wollte ich auf die Version 6.3.0 upgraden. Da ich nach wie vor kein Debian-Experte bin, Google mir hier nicht wirklich weiter hilft und ich bei diversen Versuchen über den Paketmanager Key-Errors bekomme, frage ich mal in die Runde.

Hier mal die alte Installation (Kernel 6.3.0)
  

Hier der frisch installierte Rechner
 

Vielen Dank schon mal
Gruß Jens

See above post to links for rc3 downloads.
Stupid things fixed:
Firefox-ESR installed
evince (pdf reader) installed
default kernel is aarch64 6.12.34+rpt-rpi-v8-rt (Raspberry Pi built RT_PREEMPT kernel)
