Doesn't have an option for setting LANGUAGE.

Had to use
sudo update-locale LANGUAGE="en_AU:en"

Then log out and login for it to take effect.

Thanks, that image was prepared by James Walker (Joco) one of the qtpyvcp developers.
All of these features can be set using sudo menu-config which brings up this menu.

LinuxCNC on Raspberry Pi 5

Category: Installing LinuxCNC

Just checked out your new image that you linked a couple of posts ago. Video works ok when using min hdmi to DVI adapter.
Just for those of us that are a bit silly what is the correct procedure & values to setup
1: LANGAUGE (currently unset)
2: LC_ALL (currently unset)
LANG = "en_AU.UTF-8" is fine.

Currently starting to test the new hm2_spix driver

Mesa firmware versions and updating

Category: Driver Boards

Hi Behai. I purchased a couple of these cards from the US. I built a CNC around this card and a raspberry pi five. If you want to chat about it, I’m at the top of the South Island.
 

Hi @RNZ,

Thank you very much for the offer. I appreciate that... I know nothing about CNC. I am learning at the moment.

I am learning HAL :) I have been a run-of-a-mill computer programmer, conceptually I have no problem understanding HAL, but I am not yet familiar with all the stuff in HAL yet. For example, I have learned that there is a motion module. But I don't yet understand what it is about, and its properties etc... I have much to learn till I can questions which hopefully make sense :)

Have a good weekend...

Best regards,

...behai.

The builder we have forked is based on Debian, not Rpi but we do fetch and build the Rpi  kernel from source.
That way you get the best of both worlds.
Linuxcnc is a Debian application so all the menu features are installed from Linuxcnc deb files.
Its not intended as a generic Rpi installation so it won't include any standard pi applications which could add additional latency.

Newbie looking for a hardware configuration based on Raspberry Pi

Category: Computers and Hardware

Salve,
Thank you so much for this new resource. I think i'll start playing around with it as soon as i get a Raspberry Pi. i wonder what is the maximum control frequency using this solution.
I see you are a professor. I'm currently a computer engineering student at UniCal. i wish there would be a similar project at my university :(.
Hope you do well. Thanks again.

I have been retired for a couple of years now.
If you want, I can give you the name of a UniCal teacher who, in addition to knowing me personally, could answer your questions.
In the meantime, I'll see if I can find the digital copy of this thesis which could be a good starting point for your work.

LinuxCNC on Raspberry Pi 5

Category: Installing LinuxCNC

Thanks for getting back to me.

I wanted to that that I got the image to burn onto a card through random internet searches / and re-try's. I'm sure we are all familiar with middle of the night stubbornness. LOL

Once burned the image seemed quite quite good to me with the caveat that my next step will be to get my 7i95T board configured so I haven't yet tested end-to operation.

I used saved versions of all the raspberypi.org and raspbian.org config files for apt including the keyring files that are needed. So it was quick to update/upgrade/apt install a reasonable collection of Pi specific config tools.

So thanks for making that image available.

I do have a few questions/hopes about embedding some of those tweaks into the Pi 4/5 specific IMG's.

1) Include the Pi specific APT/PGP files on the conditional build you are using for the Pi.

2) Include the core Pi executables as well with serious bonus points for adding those to the default app-lauch UI like is being done for LinuxCNC.

Those two things would substantially reduce the newbie headwinds for those that are either new or rusty on Linux.

Thanks so much for all your work!

Richard

Ciao.

Meanwhile, congratulations on the good work.

I am also Italian and have been working with LinuxCnc and Raspberyy for a long time and I took care of its translation into Italian.

LinuxCNC-RIO - RealtimeIO for LinuxCNC based on FPGA (ICE40 / ECP5)

Category: Computers and Hardware

I'm trying to get the gowin toolchain up and running on rpi5. It gives me an error when execute making all.
cnc@raspberrypi:~/riocore/Output/TangNano9K_spi_rpi5/Gateware$ make clean
rm -rf rio.fs rio.json rio_pnr.json rio.tcl abc.history impl
cnc@raspberrypi:~/riocore/Output/TangNano9K_spi_rpi5/Gateware$ make all
gw_sh rio.tcl
/opt/gowin/IDE/bin/gw_sh: 2: Syntax error: Unterminated quoted string
make: *** [Makefile:34: impl/pnr/project.fs] Error 2
cnc@raspberrypi:~/riocore/Output/TangNano9K_spi_rpi5/Gateware$ 
I see you've already mentioned this error. I downloaded and cloned the dev version and it still doesn't work. Any tips...

I see there is another option 'generic_spi'. I will test that on rpi5 too just to get that toolchain working. I don't want to take the TN9 out of the device and program on windows anymore.

Newbie looking for a hardware configuration based on Raspberry Pi

Hello everyone,
I’m not sure if I posted this in the right section, but if I did, I’ll move it to the correct place if possible.
My name is Marco, and I recently came across LinuxCNC. I’m planning to build a new 3-axis CNC (which will be upgradable to 4 axes in the future) using LinuxCNC on a Raspberry Pi 4 or 5. I’ve found there are a lot of options available and would really appreciate some help deciding which one to pick.To clarify things a bit, here are some of my findings:These are some options I’ve looked at:
1) Linumeric V3
2) 

3) github.com/ChrisWag91/PI-LCNC
4) www.forum.linuxcnc.org/18-computer/51816...lug-and-play?start=0
5) github.com/jzolee/HAL2UDPI’ve tried to choose one, but I’m still quite confused, so I thought I’d ask someone with more experience than me.
Since I’m Italian and don’t speak English very often, there’s a chance I might have made some mistakes in this post.
Thanks a lot in advance for your patience and attention!

PS. in the past, i had the opportunity to work with a 3-axis cnc running on mach3 via the LPT port. If it matters by any chance.

Real-Time Kernel with Orange Pi 4 LTS

Category: General LinuxCNC Questions

Perhaps something wrong with the kernel config? You could try to install the kernel deb that I uploaded to see if that helps. Otherwise you might need to install more software, just install a complete desktop will be the fastest route to find out.
 
from then I tried so much and still couldn't compiled a real-time image which linuxcnc be installed and its latency shows up.
Could you please guide me after placing patch (patch-6.6.63-rt43) in the /patch/kernel/archive/rockchip64-6.6 and configuring fully preemption option, what changes do I need to do?

Despite all my efforts, I was unable to successfully build a real-time version of Armbian.
Since I need a lightweight operating system, my review of the available Armbian versions showed that most of them have high latency and noticeable lag.
I am looking for a build of Armbian similar to the version provided for Raspberry Pi, which is both lightweight and optimized, with excellent latency performance.
Please help me to get through this.

Many thanks Zayoo !

i have add the code to the dev branch for testing.

if you want to use it, you can add
"rpi5": true,
to your json config

like this:
{
"name": "IceShield",
"description": "RIO-IceShield on Raspberry PI5",
"boardcfg": "IceShield",
"protocol": "SPI",
"rpi5": true,
....
