Replied by ajanfahri on topic Advice on Designing a GUI for a Custom C-Based EtherCAT CNC Controller on Linux
You're absolutely right, trajectory planning is a challenging task.

Our journey started about 20 years ago with milling and EDM machines. Back then, we were developing our software in C/C++ on DOS 6.22. I still remember spending days debugging our milling and EDM applications.

You can take a look at some of our old DOS applications here:

Later, we moved on to plasma cutting machines, and now I'm working on a laser cutting machine using Linux, Xenomai, and EtherCAT.

Your points about reliability and keeping the GUI separate from real-time motion control are very valuable. Thank you for sharing your experience and advice!

The project is still under development. The CNC software I have worked with is proprietary, so I cannot share its source code.

My current project is a separate development using Linux, Xenomai for real-time capabilities, and EtherCAT for motion control. I'm still working on the architecture and exploring the HMI approach.

Seems to be gated behind account login. Is the source code available?

I registered on the site for trying the community edition.
But could not download the deb or the src to be able to try anything.
Even the link to the manual gives a 404 error.
I would appreciate a heads-up on this thread once you get a chance to get the site working.
Thanks,

Trajectory planner is not an easy task, so i would stick with LinuxCNC for that (as do most companies using it) and do your HMI/GUI for it.
C/C++ is fine, React i have no clue (is that a version of Java script?), but whatever you end up using, make sure that if it crashes, it does not take the trajectory planner and real time stuff with it.

For me reliability is paramount, so i stick with Axis GUI mostly, i distinctly recall some 10 years back messing with Linux deleting stuff while the machine was working, i broke something, screen went black, keyboard was not doing anything, but the machine went on to finish the part over two hours after blacking out!
Having industrial machines With LinuxCNC running 24/7 for nearly 15 years without ever having any issues is something big companies can not do, of course as most of those still use windoze! :)

Where can we view the source code?

Since you asked me to show my work, I'm developing my own CNC controller using C, Ubuntu Linux with real-time capabilities, and EtherCAT.You can find more about my software development work at https://www.fahriworks.com.I'll share more technical details about the CNC project as development progresses.Wishing everyone the best with their projects!

Thanks for your suggestions! I'll look into your recommendations.(FlexGUI and QtPyVCP.)

However, I'm developing my own CNC controller from scratch rather than using LinuxCNC. The real-time control core is written in C, and I'm integrating EtherCAT for servo communication.

I'm mainly trying to decide on the best HMI architecture for my own system: a native C/C++ GUI or a modern React-based web interface communicating with the C control core through a separate backend.

I'd be interested in your thoughts on this architecture, particularly regarding reliability, real-time performance, and communication between the HMI and the control core.

Thank you. It turned out that my internet provider was having problems accessing your website. The provider has already resolved the issue. Access to your site has been restored.

It is working, but there are issues for sure, probably due to panic caused by some news yesterday and may server getting shut down completely.
Both our servers are working, but i could not access the forum from yesterday afternoon till today morning, but i could access the website just fine.
In the meantime, use a free proxy located in USA, it will work fine for browsing etc, but i would not use it to login anywhere.

Cannot access main website linuxcnc.org was created by andrey.pawl
Hello,I can open the forum (forum.linuxcnc.org) without any problems from my home computer, but the main website linuxcnc.org does not load at all (even when using a VPN). From mobile data the main site works fine.It looks like my home IP might be blocked on the main site. Is this possible? What could be the reason, and what is the recommended way to resolve such an issue?Thank you.

This looks a lot like a wiring issue, at an educated guess, one of the Mesa outputs to Y2 is tied to 5V.
