Litexcnc install

[horcsab]

Dear Peter,

I replaced the PC with a new one and I am experiencing the following installation problem.
Linuxcnc Debian 12 Bookworm PREEMPT-RT ISO freshly installed.
Python3, pip3 installed and Litexcnc installed.

Oss-cad-suite is also installed.
When compiling firmware (litexcnc build_firmware *.json --build) I always get the error "Litex is not installed. Please run 'litexcnc install_litex' first."

If I issue the litexcnc command, it shows the litex commands (build_firmware, convert, flash,...).

What can I do wrong, what might not be set correctly?

[Peter-van-Tol]

At this moment I'm on holiday, so have this answer is from my mobile phone and from my head. My apologies, more detailed answer I can send on Sunday.

I see that the documentation / error message is maybe outdated. The command litexcnc install_litex has been replaced with litexcnc install_toolchain; did you run this command? If not, this will solve your error.

Will change the error message.

This is what I used on Ubuntu. I found this in one of the discussions:

sudo apt-get update && sudo apt-get -y upgrade
sudo apt-get install python3-pip python3-wheel python3-venv
python3 -m venv ~/.local --system-site-packages
echo -e "" >> ~/.bashrc
echo -e "# set PATH so it includes user's private bin if it exists" >> ~/.bashrc
echo -e "if [ -d "$HOME/.local/bin" ] ; then" >> ~/.bashrc
echo -e " PATH="$HOME/.local/bin:$PATH"" >> ~/.bashrc
echo -e "fi" >> ~/.bashrc
. ~/.bashrc
pip install litexcnc[cli]

litexcnc install_toolchain --user
sudo env "PATH=$PATH" litexcnc install_driver
. ~/.bashrc

Of course Peter is way more competent. Maybe this helps

[Peter-van-Tol]

You're spot on with the recipe 👍, cannot improve on that.

kzali and Peter,
Thank you for your help!
The problem was solved, I reinstalled the machine and then installed it according to the above instructions. It worked!

Have a nice rest everyone!

So, next problem,

firmware build...

What am I not setting correctly in the pwm section?

[horcsab]

I changed the keyword to pin, but the error is the same.

[Peter-van-Tol]

The error is different, it now says it expects the name of the pin. So this means you have to install the latest version from GitHub instead of PyPi.

pip install git+https://github.com/Peter-van-Tol/LiteX-CNC

[Peter-van-Tol]

Above should install the development version, which includes the feature you are looking for.

No further installations required.

[horcsab]

Thanks Peter!
It worked!

[Peter-van-Tol]

You're welcome.

Please share your experience with LitexCNC.

[Peter-van-Tol]

I see this as a bug. Break down of what happens: - the error only happens when memory cannot be allocated for a module, i.e. `pwm` in this case; - I don't think this is hardware related, so most-likely the byte with the number of instances received from the FPGA is zero (which prevents allocation of memory); - either in the firmware there is an error or in the driver. Going to check which part has been changed with the latest modification, as this behavior I didn't experience before. Op za 17 aug 2024 om 08:57 schreef Csaba Horvath ***@***.***>:

Quick check: after installing the development version of the firmware, did you also re-install the driver? There has been a change in the driver which could explain the behavior you are experiencing. Op za 17 aug 2024 om 15:58 schreef Peter Van Tol ***@***.***>:

A driver update solved this problem.

However, I find that the ethernet connection is disconnected for some reason. During continuous pinging, the connection is interrupted more and more often, and then the connection with the card is terminated.

Could the card be faulty?
5A-75E v8.0

[horcsab]

I tried a previous firmware setting on the card and it works.
I am attaching the previous json file, this ok.
CSABA-5A-75E.json

And new json, is not ok.
FUW400-5A-75E.json

If you have some time, could you check what the error could be? I can't find it.
Thanks!

[horcsab]

Currently, 20kHz PWM is set for the test, but I will reduce this. I am attaching the existing documentation.
At the moment, I only have the basics, I still have a lot to improve on the settings, and the conversion electronics are not perfect yet.

I replaced the 74245 circuits on the colorlight board with SN74CBT3245APWR.With this, the level adjustment was solved and the outputs became bidirectional.

[Peter-van-Tol]

I like the schematics! Gives inspiration of creating my own 0-10 Volt converters.

As I can see in you your HAL, the servo's are running in position mode. Even when running as low as 1 kHz, I have the feeling that the resolution of 400.000 positions along an axis is too low. This ultimately depends on the size of the machine whether this is acceptable. Whilst having tinkered on PWM anyways, I think adding dithering is a good next step. The aim is to make PWM with full 32-bit resolution, independent on the frequency.

[Peter-van-Tol]

See also #108

[horcsab]

Sorry for my bad English. I will try to describe my experience.

I still don't understand a lot about linuxcnc, that's for sure.

The motor drive receives an analog signal, the range of which is +/-10V. According to my experience, it is sufficient to control this with a resolution of 1-2mV.

If I understand correctly, the positioning of linuxcnc works in such a way that the incremental encoder on the motor axis gives the position. And in linuxcnc there is the command position. If these two values ​​differ, the regulating +/-10V signal is created from the difference between these two values. The larger this error is, the larger the signal is, of course with reversed sign.

I don't understand why the resolution of 400,000 would be insufficient for PWM. A value of 40000 should be enough.
I just tried driving an old SOPREL DC motor on the table, which has a 500 pulse/revolution encoder at the end of the shaft.
The encoder is processed with 4x resolution by Linuxcnc and apparently works perfectly. Both at low and high speeds. The maximum speed of the motor is 3000rpm.

[Peter-van-Tol]

My bad, as I didn't read well enough your HAL-file. The output for your servo-drive determines the speed, not the position! In case of speed, the resolution is well enough. I can still learn everyday! With your explanation, I can follow what you are doing and it should work.

BTW: your English is good enough. It isn't my primary language either!

I would like to recommend to install a newer version of LitexCNC, by using the following command:

pip install git+https://github.com/Peter-van-Tol/LiteX-CNC@119-feature-request-revamp-watchdog

In this version, a few bugs have been resolved and new features have been implemented:

• better watchdog ([Feature request]: Revamp Watchdog #119)
• user LED and button supported ([Feature request]: Support user LED and button #117)
• more stepgen modes supported ([Feature request]: Add PWM/direction and UP/DOWN to PWM #104), also fixed bugs in the stepgen, making stepping at higher rates possible
• different PWM modes supported ([Feature request]: Add PWM/direction and UP/DOWN to PWM #104)
• fixed version of the toolchain

To use these version, it is required to re-install both the driver and toolchain:

litexcnc install_toolchain --user
litexcnc install_driver

See attached file with the required changes.

config.json

If you want, I can also share the build firmware.

Could you try again. And if it does not work, try to get some more information on the error with git status as suggested in the error.

[romanetz]

Well, I had the same issue. Litexcnc, been installed from pip repository, creates script named litexcnc in virtualenv/bin directory. Litexcnc, been installed from git repository, doesn't create the script but is callable in virtualenv via call: python -m litexcnc вс, 5 янв. 2025 г. в 00:27, Peter-van-Tol ***@***.***>:

[Peter-van-Tol]

To install the driver, you need sudo to run. However, when running sudo, it will not take the correct environment.

You can use the following command, to keep the current PATH variables untouched:

sudo -E env PATH=$PATH litexcnc install_driver

or, when litexcnc is not recognized:

sudo -E env PATH=$PATH python -m litexcnc install_driver

I thought it was in the documentation, but this was not released (yet). My bad...

[Peter-van-Tol]

Version 1.3.0. has just been released. Also, the documentation has been revised!

[EhsanRasouli1371]

🙏🙏🙏

[romanetz]

Just change permissions of the destination folder, make it writable to regular user: sudo chmod 777 /usr/lib/linuxcnc/modules Also, of course, a recompilation and reflashing of the board is needed. вс, 5 янв. 2025 г., 14:05 EhsanRasouli1371 ***@***.***>:
