New LinuxCNC Multi-Channel System – Looking for Testers & Feedback

Category: Show Your Stuff

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,

Advice on Designing a GUI for a Custom C-Based EtherCAT CNC Controller on Linux

Category: Show Your Stuff

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! :)

Show Your Stuff: My Custom CNC Controller

Category: Show Your Stuff

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!

Advice on Designing a GUI for a Custom C-Based EtherCAT CNC Controller on Linux

Category: Show Your Stuff

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.

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.

New LinuxCNC Multi-Channel System – Looking for Testers & Feedback

Category: Show Your Stuff

Hi all,

a quick update from the multichannel LinuxCNC project I posted about earlier (looking for testers with real machines). Everything now lives on our new site: www.cnc.gmbh

What you'll find there:

Try it online – a live test environment where you can run the multichannel system in your browser, load programs for several channels and see how the synchronisation (wait marks, channel coordination, Sinumerik-style syntax) behaves, no install needed.

Download - the current .deb packages for Debian [12/13] (amd64, [arm64]) plus the full source code. Build instructions are included.

Config generation offer, since the most common question is "how do I get my machine running with it", we're offering, for a limited time, to generate the complete LinuxCNC configuration (INI/HAL, channels, axes, spindles, I/O) for your retrofit, works for existing LinuxCNC setups you want to migrate as well as brand-new retrofits. Send us your machine data and drive/IO hardware via the form on the site, and you get a ready-to-run multichannel config.

Feedback, bug reports and especially reports from real machines are very welcome, either here in this thread or via the site.

Thanks,
Daniel

Jogging a 2nd Spindle

Category: AXIS

Right now I don't think there is any form of "active" spindle. There is the primary spindle which responds to commands with no spindle designation or $0 commands. And all spindle commands intended for spindles other than the primary one must be appended with with $n, where n=the spindle's designation number.

Before the addition of multiple spindle support, one of the main work arounds was to create custom M-codes to designate "active" spindles that would then receive the standard spindle commands. But that isn't how the current multi-spindle support works. In some ways I think that is almost a better way to make it work. And It still can be done this way, but it does make for a much more complicated hal configuration.
