They are numbered after the network chain. 0 is closest to the master, 1 is next, 2 is nextnext and so on .
Can't change that afaik. Rearrange the network cables if you have to have a certain numbering.

Happy it was so easy this time :)

What version of mesaflash and LinuxCNC do you have?

mesaflash --version


To install the latest LinuxCNC version, go to github.com/LinuxCNC/mesaflash
 then scroll to the bottom for "Quickstart" instructions.

Okay, I just copied the linuxcnc config directory from monokrom-vcp to my config directory.

Go sim.monokrom/plasma
Code:
debian$ linuxcnc xyz.ini
Gives the following, missing module imp which is deprecated when searching for it.
Code:

There is a yellow blinking light. I'll try to see if I can measure anything on 1x with my multimeter.
Thanks for all your help and the awesome mesa products.

On another forum, I saw the os3t-01 from robot3t.com. It's an ohmic sensor that can supposedly handle hf.
Does anyone have any experience with this company or their products?

Hello! Please tell me how to update Mesaflash to the latest version and why it is missing in the latest version of LinuxCNC? Also, please tell me which firmware version I need to flash the board to get 4 axes with 4 encoders? Thank you very much!

You are completely correct. Do you have a clue as to why slave 3 switched to slave 0, and is there a way to force the order?

I few of the dependencies were missing. 
Code:
debian@plasma:~$ monokrom_plasma --install Traceback (most recent call last):   File "/usr/bin/monokrom_plasma", line 8, in <module>     sys.exit(main())              ~~~~^^   File "/usr/lib/python3/dist-packages/monokrom/plasma/__init__.py", line 8, in main     monokrom.main('plasma', opts)     ~~~~~~~~~~~~~^^^^^^^^^^^^^^^^   File "/usr/lib/python3/dist-packages/monokrom/__init__.py", line 104, in main     copy_tree(src, os.path.expanduser('~/linuxcnc'), update=1)     ~~~~~~~~~^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^   File "/usr/lib/python3/dist-packages/setuptools/_distutils/dir_util.py", line 127, in copy_tree     raise DistutilsFileError(f"cannot copy tree '{src}': not a directory") distutils.errors.DistutilsFileError: cannot copy tree '/home/debian/.local/share/monokrom/linuxcnc': not a directory

I hope the --install is the next step.

Do you have a blinking yellow light on the THCAD?

If you set  the THCAD frequency divider to 1X you can probably
measure a change in the frequency as a voltage change on the F+
or F- relative to ground. Not sure of the polarity but full scale
should be about 2.5V at full scale and maybe 0.3V at 0V

I would need to study a bit about the probe wiring.

Replied by Gogonfa on topic Help with Wireless Handwheel XHC-WHB04B-6 (wrong Product ID)
Thanks @rodw,
today I built LinuxCNC 2.10-pre directly from the git repository, using the 6.12.48+deb13-rt-amd64 real-time kernel together with the Probe Basic GUI.Getting Probe Basic up and running was a bit tricky — some of the Python libraries it relies on are deprecated and no longer available in Python 3.13, so I had to make a few adjustments. But it’s working now!I also changed the ID for the wireless handwheel (not yet tested), and EtherCAT is running as well.

Since replacing the 7i97t, I haven't had any of the ohmic wired up while the plasma is running. I have only tried to get it working with the plasma off, so the 7i97t encoders should be fine.
I was more referring to the thcad output.
Can measure voltage between f+ and f- with the ohmic circuit open and again with it closed to test the thcad?

For the capacitor you mentioned, would I wire the torch tip to capacitor and the other end of the capacitor to star ground. Then run a separate wire from torch tip to thcad? Or would I wire both the star ground and the thcad to the capacitor?

A question about Axis Position Labels. It says labels including all offsets. In 'dro_lb_z' G43 / G49 has no effect

And remove the [url= or [/url] from the sources. I don't know what is going on with this editor.

This is just from the top of my head. I do not know if all steps are necessary:

1) Prerequisites for python3:
Code:
sudo apt install python3-pyqt5 python3-dbus.mainloop.pyqt5 python3-pyqt5.qtopengl python3-pyqt5.qsci python3-pyqt5.qtmultimedia \ python3-pyqt5.qtquick qml-module-qtquick-controls gstreamer1.0-plugins-bad libqt5multimedia5-plugins pyqt5-dev-tools python3-dev \ python3-setuptools python3-wheel python3-pip python3-six python3-docopt python3-qtpy python3-pyudev python3-psutil python3-markupsafe \ python3-opengl python3-vtk9 python3-pyqtgraph python3-simpleeval python3-jinja2 python3-deepdiff python3-sqlalchemy git python3-distro \ python3-serial

2) Then I followed those instructions for a development install:  www.qtpyvcp.com/install/dev_install.html

3) Adding:
Code:
read:deb [arch=arm64] [url=https://repository.qtpyvcp.com/apt]repository.qtpyvcp.com/apt[/url]

to the sources list in:
Code:
/etc/apt/sources.list.d/kcjengr.list


Note that if you have an x86 64-bit CPU it should be something like
Code:
read:deb [arch=amd64] [url=https://repository.qtpyvcp.com/apt]repository.qtpyvcp.com/apt[/url]

4) Finally:
Code:
$ sudo apt install python3-monokrom

As mentioned, this is just as I roughly remember it. I could be off here. I've tried a lot of things till I was successful.
