Matsuura retrofit

Aptly-named forum user “skunkworks” has been working this year to retrofit a Matsuura MC 500v2. The long-running forum thread covers topics like rigging up a spindle encoder that detects the passing teeth of a 69-tooth gear, wiring up a whole pile of Mesa hardware, through setting up the tool changer and doing some rigid tapping.

Tiny, tiny screws

LinuxCNC developer Chris Radek originally wrote spindle-synchronized threading before the software was even called LinuxCNC. Much later, he used LinuxCNC to create these crazy-small screws for his glases frames (the US dime shown for scale is 18mm diameter): Blog post

LinuxCNC 2.7.5 released

LinuxCNC 2.7.5 has been released.

This release includes a fairly large change to the controller, intended to make Abort (eg, hitting Escape while running a program in Axis) work more correctly. This change also affects controller startup, including the processing of [RS274NGC]STARTUP_GCODE. Please be on the lookout for any surprises in these areas, and let us know if you notice anything amiss.... read more

4-axis milling on a Cincinnati

Forum member LAIR82 has retrofitted this Cincinnati Milacron with 4 axes. In this video, you can see a sample of the rotary axis, and a glimpse of the “gscreen” gui. In another video in the forum thread you can see the toolchanger in action. It is controlled with the Coursel Component “and a pretty heft chunk of ladder logic.”

Joints/Axes branch finally merged!

The joints-axes branch has been merged into the master branch!

Joints/axes was a project to separate “joints” (roughly: motors) from “axes” (roughly: cartesian coordinates), in order to better support machines where a single motor does not directly drive motion along an axis, such as gantry machines, delta robots, robot arms, hexapods, and similar.

Everyone running the development version of LinuxCNC (what’s tentatively called “2.8~pre”) will be affected by this change.... read more

LinuxCNC 2.7.4 released

LinuxCNC 2.7.4 has been released.

This release fixes bugs all over: in hm2 sserial, GUIs, xhc-hb04, hy-vfd, stepconf & pncconf, and in the docs. 2.7.4 adds support for RTAI 5.0, though we have no debian packages yet, sorry. It also adds a component to help drive some kinds of gantry machines (named “gantry.comp”).

All 2.7 users are encouraged to upgrade.

My thanks go to all the people who have helped out on the forums, mailing lists, and IRC, to the poeple who brought this round of bugs to our attention, and especially to the developers who have committed bugfixes and improvements:... read more

RTAI 5.0 support merged

Support for RTAI 5 has been merged into LinuxCNC 2.7 (and into the “master” development branch).

RTAI kernel packages are available for Debian Jessie, based on Linux 3.16.7 and RTAI 5.0-test1. At this time only i386 (686-pae) is supported, we’re still having trouble with amd64.

In order to use it, you need to install Jessie (i386) using the regular debian.org installer, add “deb http://linuxcnc.org jessie base” to your sources.list, install the linux-image and rtai-modules packages from there, and reboot.... read more

As always, thanks to everyone who contributed:... read more

New RTAI kernel: Linux 3.16.7 with RTAI 5.0-test1

Update: RTAI-5 support has been merged into mainline. The 2.7 and master branches build and run right out of the box. More info here.

New RTAI kernel packages are available for Debian Jessie, based on Linux 3.16.7 and RTAI 5.0-test1.

This new realtime kernel is not ready for widespread deployment yet. I’m soliciting early testing from developers and advanced users who are comfortable manipulating apt sources, installing kernel packages, and building linuxcnc from source.... read more
