Hi,

Still in regard to the image linuxcnc.org/iso/rpi-4-debian-bookworm-6...25-01-27-0404.img.xz, I have found the following information useful:

1. The desktop is XFCE, we can find out using the command echo $XDG_CURRENT_DESKTOP.

2. In regard to enabling Wifi.

This image comes with no network manager tool, nmcli is not available.

ChatGPT suggests the following steps. And I have carried them out successfully.

Please note, I had to switch to superuser to run the below commands.

To switch to superuser, use sudo su -.

a. Connect Using wpa_supplicant (If No NetworkManager).

b. Generate a configuration file:

[
wpa_passphrase "<WIFI_NETWORK_NAME>" "<WIFI_PASSWORD>" | sudo tee /etc/wpa_supplicant/wpa_supplicant.conf
]

c. Start wpa_supplicant:

[
wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf
]

Please note wlan0. I think this is called network device name. We can find it out using the command ip link show, there are several output entries, I just guessed which on is the Wifi one, and lucky it was correct

d. Obtain an IP address via DHCP:

[
dhclient wlan0
]

e. Persist WiFi Connection (For Boot Time). Ensure it's enabled at boot:

[
systemctl enable wpa_supplicant
systemctl start wpa_supplicant
]

f. Test connectivity:

[
ping -c 4 8.8.8.8
]

It should give successful responses.

g. I restarted the machine. And still have Wifi, but there is no Wifi icon. I have not been able to get it to display.

3. In regard to Remote Desktop Connection.

I followed this article phoenixnap.com/kb/debian-remote-desktop and get it to work successfully.

Connecting from my Windows 10, the desktop just displays rubbish. It is not usuable.

4. In regard to directory sharing.

Samba works successfully, just like in Ubuntu and Raspbian. The setting up process is pretty much the same.

Thank you and best regards,

You can also open the synaptic manager and search:

linux-image

Right click the latest rt preempt signed kernel version and select for installation. Then click apply in the top menu. See if that works

Sorry it looks like it's maybe missing in the kernel build.

Restart and try running again

Copy each of the missing dependency names and run

sudo apt install dependencyname

once the missing deps are installed it should complete update without complaint. I've not seen that before though.. kind of odd

After restarting, I ran

sudo apt update
sudo apt upgrade

And again, it came back with errors, so I ran

sudo apt --fix-broken install

It also came back with errors:

 

This report is much shorter. Reading through it, it isn't apparent to me what is happening.

Much appreciated, you've been a great help,

Once again thanks.....oh if there's anything you feel that maybe missing in the thread I mentioned feel free to add to it. It'd be great if, as a community, we could try and assemble a lot of info in the one place.

Cheers

Hi Rob,

Thank you to you, too. Without your help, I would not be able to get through this so quicky. I apologise for my late reply. I got caught up in some Fusion 360 stuff

I think this is what you meant: forum.linuxcnc.org/9-installing-linuxcnc...-4-5?start=10#320959 ?

Thank you and best regards, Rob.

Hi,

Thank you for the thread. It is very informative.

In regard to the image linuxcnc.org/iso/rpi-4-debian-bookworm-6...25-01-27-0404.img.xz
and locale, I have been able to verify that locale en US.UTF-8 works for PNCConf.

And after using menu-config to set the locale, I had to restart the machine for it takes effect.

After machine restarted, we should verify the locale. On a terminal window type locale the output should match.

-- I did try to set the locale to en AU.UTF-8 and it did not work.

Thank you and best regards,

...behai.

 

(Sorry for double posting. Cant edit last post, can only see the block quote when i try to edit)

I found a solution for my missing WiFi connections.
Second method mentioned in the top reply. (first method didn't work for me)
askubuntu.com/questions/71159/network-ma...s-device-not-managed

***
.....
Then open the file:
sudo nano /etc/network/interfaces
Delete everything in that file and copy and paste the following:

auto lo
iface lo inet loopback

Save, stop and start network manager:

sudo service network-manager restart
***
I had to reboot my whole system but after that WiFi works like expected.

Try running update upgrade again, if errors are encountered, run the following

sudo apt --fix-broken install

To set up my computer, I followed Dr. Dflo.
www.drdflo.com/pages/Projects/CNC-Mill.html#linuxcnc
Click on linuxcnc from the left menu.The last line of the paragraph has a specific link for setting up for Probe Basic, so that is what I have been following.

He lists this link: kcjengr.github.io/probe_basic/quick_start.html

From here, I downloaded the Debian 12 bookworm image (on my win 11 computer) and followed the instructions to make a bootable usb drive. I probably used the link to make the image but am not 100% sure......it was a simple utility like what is listed.

I ran that usb drive on my new computer for this mill: Intel NUC mini desktop Core i5-9300H, 8GB ram, 256 GB SSD. It removed windows and only Debian is installed.

It appears it was Debian 12.2.0, as you can see from the first commands I typed into the terminal (text file below).

I just updated Debian by using sudo apt update and sudo apt upgrade from the terminal.

It gave me an error on lines 705 and 722:

Let's see if I attached the file correctly.....
 


What does this error mean and how do I address it?

I have not yet restarted the computer, but ran the command to check the debian version and it is still 12.2.0. I will do a restart and check again.



 

I can at least confirm a pi 5 that is able to find WiFi networks. In my case nmtui did work I chose something I remember was called ‘activate network’ and it would show a bunch (and prompt for password).

With kind regards,
Jairo 

edit: this is on the latest linuxcnc image 2.9.4 by rodw 

Thanks for the reply jairobbo!
That is really weird. I did exactly that but my list appear empty. Fresh install 2.9.4 and thensudo apt install network-manager
Did you use the 2.9.4 from downloads page, I think thats rodw's, right? Version of Rpi5? (I have the 4GB)

I also tried sudo apt install network-manager-gnomeAnd when I pop down the little menu there is a grayed out text "device not managed" and under that is only VPN connections. Any idea what might be off on my system?

I am new to LinuxCNC. I just performed a fresh installation using (rpi-4-debian-bookworm-6.12.11-arm64-ext4-2025-01-27-0404.img) with the Remora component. Can someone guide me step by step on how to set it up with a BTT SKR PRO V1.2?


Thanks,

If by daughtercard you mean the 7I84U, any firmware with a sserial port will do.

(basically and 7I96S firmware that does not use the serial expansion for modbus etc)

Yep, the 7I84U would be the daughtercard to the 7I96s. 
OK, I will try making it work with the FW you linked above.
As an aside, I have it downloaded already but have a bit of an issue making it show up in MesaCT even though I think it's in the right folder, but that's probably just me still overseeing something - will read some more posts and/or try mesaflash in the terminal. 

I'm new here and have same servo so decide to try your setup files. I was not able to achieve success with your files like MWalz did.
Maybe you can help me? Here is my output:

Yeah the whole switch from Ubuntu to Debian cost me a ton of money. I'm a Linux guy myself and I can work in any Linux distro even if it hurts my eyes, but we couldn't do that to our customers, most of whom are scared of Linux in the first place. We stayed on 2.6 until UEFI forced us to update to 2.8 and then again when parallel ports finally dried up and mesa cards forced us onto 2.9. Now PC motherboards are almost obsolete in general, and the switch to rpi was forced, but has actually been pleasant thanks to a lot of yours efforts
