LinuxCNC 2.9.2 has been released.

This is a bugfix release, with the most obvious change being that run-from-
line in the Axis interface should now be working again.

Packages have been prepared for:

Buster - uspace - amd64 (PC) armhf (Pi) arm64 (Pi with 64-bit kernels)

Buster - RTAI - amd64

Bullseye - uspace - ams64 (only)

Bookworm - uspace - amd64, arm64

Bookworm - RTAI - amd64

For existing users of 2.9.1 on the above platforms this should be offered as
an automatic update.... read more

LinuxCNC 2.9.1 has been released

(there was no 2.9.0 release)

This marks a major new release of LinuxCNC.

Due to the difficulty of supporting both Python3 and Python2 and various out-
of-date libraries the 2.9 release of LinuxCNC is only supported in Debian
Buster or later, Ubuntu Focal and later and Rasbian 12 and later. Furthermore
we are no longer building any 32-bit versions of any packages.... read more

There will be a meeting of LinuxCNC developers, users, and enthusiasts in
Stuttgart, Germany, during the weekend from Friday October 6th to Sunday
October 8th 2023.

This will be a pretty informal meeting, there is no registration, no entrance
fee, no badges, no speakers, and no set agenda. It is a chance for people
interested in LinuxCNC to meet each other, show off their projects, and talk
about issues, fears, hopes, and dreams.... read more

LinuxCNC 2.8.4 has been released.

This release, unusually soon after the 2.8.3 release, is mainly to address a
side effect of the ongoing chip shortage. It has become difficult to build
most of the popular Mesa hardware interface cards. One card that is reasonably
available, the 7i96S is not supported by LinuxCNC 2.8.3. This release adds
support for the 7i96S to the 2.8 branch.

We also welcome a new language to the translations, a Czech translation is now
available for Gmoccappy.... read more

LinuxCNC 2.8.3 has been released.

This is, again, mainly a bugfix release, but includes a new GUI
(“Craftsman”)built on Glade.

All users are encouraged to update.

A new ISO is likely to follow in time, but this should be an automatic update
for most installed 2.8 systems.

Note that at the moment there is no kernel-space RTAI (2.8.3-rt) package for
Buster. It is likely that a 2.8-rt package will be made available in a few
days, but it is possible to run linuxcnc-uspace on an RTAI kernel if the
additional package linuxcnc-uspace-rtai is installed.... read more

After many months of work by Petter, Jérémie, Steffen and Hans the LinuxCNC
documentation has been restructured into a format that can be cloud-translated
by Weblate.

This allows anyone to translate the docs from English into another language
that they also speak.

You can help!

Spotted on Hackaday, a packing robot for Raspberry Pis controlled by LinuxCNC
running on a Raspberry Pi.
The blog post gives quite a detailed description of how the system is
controlled using a mixture of Ruby scripting and the linuxcncrsh remote
control interface.

Spotted on YouTube, LinuxCNC integrator Halász Attila has retrofitted a
sizeable Heckler and Koch BA25 machining centre. The tool changer looks to
have been very neatly integrated.

LinuxCNC has been accepted into the main Debian
distribution. This means it is
now possible to install a fully functioning LinuxCNC system, including a
Preempt-RT realtime kernel
suitable for running real hardware, entirely from official Debian package
repositories.

This is a huge milestone and I’m very grateful to Steffen Möller and Petter
Reinholdtsen from the Debian project for joining us and providing extensive
help and support in this effort.... read more

LinuxCNC 2.8.2 has been released.

This is mainly a bugfix release, though it also adds a new HAL component
(“sendkeys”) for creating input device events from HAL pins.

All users are encouraged to update.

In addition there is a new RTAI kernel based on 4.19.195. This comes with a
new version of RTAI 5.3. Both should be automatically installed with the
2.8.2-rt version of LinuxCNC. If you are using the ISO install or know that
you are running the preempt-rt kernel this need not concern you.... read more

page for information on how to connect,
including directly in your web browser.... read more

Recently mentioned on the forum is a bioprinting BCN3D Moveo robot controlled
by LinuxCNC. The hope is that one day a similar system could print replacement
body-parts in-situ.

If you were wondering what 5-Axis TCP kinematics could do, this is a good demonstration. The tool continues to run through a simple pattern of squares while the workpiece rotates and tilts underneath it.
