Download problem found and fixed

Thanks to everyone who reported that the Debian packages could not be downloaded from www.cnc.gmbh/download even when logged in. The cause is found and fixed, please try again.

What happened: the shop server read the whole package (about 30 MB) and pushed it to the browser in one piece. The web server behind the shop allows only two seconds per send operation, so on a normal internet connection the transfer was cut off before the first chunk was through. The browser then received an empty file, or nothing at all. The login itself was never the problem.


If it still does not work for you, please post the file name, your browser and roughly the time of the attempt so I can check the server log.

You're absolutely right, that's exactly the point.
I created an issue on github linuxcnc-ethercat and received information that the problem was not only known to the authors, but had been solved long ago. You just need to download the deb package from the getset branch instead of main, or set a different source in the apt settings (I haven't checked it yet, but I believe it works).
But how is an average user who is not a LinuxCNC developer supposed to know about this?
He'll just do exactly what I did - update what he has installed, find out it doesn't work and start swearing...

Small update: I made a free online version of the OD turning cycle, so you can try it without installing anything.

turngcode.com/en/generator/?utm_source=l...m_campaign=generator

Enter stock and finished diameter, length and cutting data - it shows the passes in a 2D view (same simulator as in the program) and gives you a ready .ngc for LinuxCNC (G7 or G8, G54-G59). The calculation runs on the server and is the same as in the program, line for line. No sign-up, no email.

The other 11 cycles are still only in the program. If you try the online one, I'd like to hear what is missing or wrong - especially from those who turn on LinuxCNC every day.

Hi everyone,

We're looking for testers for a new LinuxCNC interface to Dynomotion's KFLOP (USB) and Kogna (Ethernet) motion controllers.

LinuxCNC's G-code interpreter and user interfaces (AXIS, gmoccapy) drive our third-order, jerk-limited trajectory planner (TP3), with velocity, acceleration and jerk limits per axis or per actuator. Motion execution and servo control run on the controller, so the PC needs no realtime kernel. It installs as its own LinuxCNC build in your home folder, beside any LinuxCNC you already have: LinuxCNC 2.10 built from source with four small patches, its realtime motion module replaced by a userspace one that talks to the controller. Initialization and machine functions are C programs on the controller, and a simulation mode runs without hardware.

Demo, LinuxCNC in Debian inside VirtualBox on a Windows PC:


(Please set quality to 1080p for better viewing)


Getting started: the QuickStart covers the VM, the install, the controller firmware and the first runs; on a Debian 13 PC the same install script should do it without the VM. The source is TomKerekes/KMotionX on GitHub , and FEATURES.md lists what works and what does not yet.

This is under development, and we would like to hear how it does on different machines and configurations. Please post in this thread, successes as well as problems: which controller, what you were doing, any error messages and the relevant configuration files, and install.log for installation problems.

Thanks for helping us test it!

Hi automata, hi NWE,

thanks a lot for trying it out and for reporting this and sorry for the trouble. You're right: the download section and the manual link on cnc.gmbh are currently broken. The site was just migrated to a new system and the file links didn't make it over correctly.

I'm fixing it right now and will post here as soon as the .deb packages, the source code and the manual are downloadable. Your registration stays valid, so no need to sign up again.

Thanks for your patience and looking forward to your feedback once you have it running!

Daniel

I see an email half way down the front page yurtaev.com/ with instructions to contact that email for purchasing cards.

What association does your software development have with open source LinuxCNC forum? Free advertising?

getting the same errors here

I can't find a link on your website to the CNC controller software.
The FahriWorks CAD and the CNC Monitoring System are cloud based services? I disassembled the CNC Monitoring System file I downloaded from fahriworks.com, I see it would send all CNC telemetry to api.fahriworks.com then I have to log in to your server with a pin to view my machine data.

Thanks for checking it out!

The source code isn't publicly available, so I'm afraid I can't share it. The page isn't actually a login screen; the frontend is built with React, and the backend is written in C/C++.

However, I'd be happy to explain how it works or help in any other way if you're interested.

Thanks again for your interest!

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:
doscapture.fahriworks.com/

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,
