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

And finally for up to date info on the RPi and the images please jump to:
forum.linuxcnc.org/9-installing-linuxcnc...the-rpasberry-pi-4-5

Hopefully this will end up as a one stop for most issues and advice.

Regarding Network Manager

This will install the panel applet and network-manager making managed networking easier to setup.

For a description on networking the debian way.
wiki.debian.org/NetworkManager

I'll admit I'm not a huge fan of the std xfce panel setup, but that's easy enough to change.
Actually I prefer MATE and have made images for myself with the MATE desktop without any of the XFCE4 hangover, but it is simple enough to install MATE on the std linuxcnc image, whether amd64 or arm64.

With regards to wifi & networking in general.installs network manager & the gnome applet. The reason this has been left out is because there were some latency issues, I think with the 12.x series being far better this is not such an issue.
I like the gnome applet as I like to turn wifi off when running Linuxcnc.

If a touch screen enumerates as HID it will just work. As the images we build use the RPi-Linux sources it may be a kernel module that isn't included in our build to support non HID touchscreens.
On screen keyboard, just a package we don't include.
Reasons for not using RPIOS, the fact that it uses wayland as a default and X compatibility layer is very slow, so slow that there is a significant difference when running latency tests between wayland (as stock) and changing to X.
Branding is also an issue, something I really want to deal with. Debian isn't so restrictive, hence the reason the PC images changed from Ubuntu to Debian.

There is also a thread some where on the forum regarding Linuxcnc on RPIOS. The topic author slips my mind at this moment.

I think I'm not far from the goal?
Does anyone have a config file for functional linuxcnc 3 axes?

refer to the remora documents, and the github repo

I'm going to replace the BOB and convert it to the EC500. Will Remora firmware work with the probe basic gui?

you can use whatever linuxcnc gui you choose

I was thinking about this, trying to think of a general process.
Thinking out loud:
What you are asking for is similar to coupling axes on DROs.
In your case it seems Z (linuxcnc controlled?) axis is the bed and your manual one is the quill.

This is quite a common machine layout.

I feel like using an linuxcnc's extra joint for the manual quill would be appropriate.
This would display the extra joint position in the GUI.
Then tell the GUI to couple the joints for Z for touch off.
maybe the GUI could be set up to show the extra joint position naked when 'uncoupled' and combined when 'coupled'.
Not that far from what you are doing anyways, just feels a little more official/
AXIS sim has a sample config to show extra joints so you could see the idea with the DRO display.

Thoughts?

Good morning. I wanted to ask for clarifications on a problem that I encounter both on a real machine and on sim/axis. The version is 2.9 pre0.
If I command m3 s800 and after g33.1 z-50 k1, the tapping is performed correctly, the spindle turns in m3, stops with deceleration after z-50 and returns to m4 until it exceeds the initial z in deceleration, and then returns to the initial z.

If I command m3 s1000 and after g33.1 z-50 k1, the tapping is not performed correctly, the spindle turns in m3, the z reaches -50 and no longer returns to z +, I send back with the spindle rotating.

If I command m3 s2000 and after g33.1 z-50 k2 the tapping is performed correctly, the spindle turns in m3, stops with deceleration after z-50 and returns to m4 until it exceeds the initial z in deceleration, and then returns to the initial z.

If I command m3 s3000 and after g33.1 z-50 k2, the tapping is not performed correctly, the spindle turns in m3, the z reaches -50 and does not return to z +, I return with the spindle rotating.

This value the spindle are on real machine, on sim have value for spindle velocity much hight, but problem is the same .
on linuxcnc 2.9.0 pre0 is the same at 2.10.0-pre0

On fanuc system, the spindle have 2 acceleration value.
One for velocity mode, when work in m3 or m4 and the second accelleration for tapping.

i have test change encoder resolution and mesa card , but the problem not is hw.
some test:
if change acceleration the spindle and is much fast , the m3s1500 is ok.
The acceleration value the spindle change reaction on return the z axis .

because ?

Yes, thank you all for your help, my T420 was the problem, switching to an other PC fixed it

But now i have a new problem

I need this custom pinout on my Card to run my Stepcraft D420

How do i get a bin File for the 7i92TM to match that?

I happen to like the RPIOS default desktop (LXDE-PI) way better than LinuxCNCs (XFCE or whatever it is) and a host of other reasons, including the Raspis built in touchscreen support and on-screen keyboard. Everything, including wi-fi, just seems to work. Its easy to install LinuxCNC on it. If anyone is interested, I'll start a new thread.

I use a momentary switch and will insert a 4.7 k ohm resistor. Thanks for your help!

You would need to add an external resistor from 3.3V to each input (0 through 7)
connected to a switch, assuming the switch switches to ground (a 4.7K resistor is a reasonable value)

If the switch/button has NO and NC contacts you can do without the resistor, but a normal
SPST switch needs the resistors.
