I have even installed Debian 9 from an ordinary Debain ISO (not Linuxcnc), then installed the Preempt-RT kernel using Synaptic (Ordinary Debian repositories), then installed Linuxcnc from Buildbot also using Synaptic. (without having to jump through any special hoops).
Now for the asterisk, That was only in a VM to see if it could be done, I never tried it on real hardware, or ran a machine with it. Todd Zuercher P.

The closest currently is the LinuxCNC + 2.7.14 Stretch ISO here: http://www.linuxcnc.org/testing-stretch-rtpreempt/ Though for X86 its pretty easy to build a Preempt-RT kernel (even a very new 5.xx kernel for new hardware support) and run linuxCNC on most Debian based distributions (I have it running on Ubuntu 18.04, Mint 18, Mint 19, Debian Stretch, Debian Wheezy, BunsenLabs Linux ATM) > > I've also noted that anything for the my pi has done a vanishing act > also, no updates for my pi driven Sheldon lathe in months now.

Then it generally runs well till the next power bump. I haven't noticed any KB issues with our RPI test machine (its been running 24/7 with a SPI interfaced 7C80 since last July, it _was_ neccesary to enable hardware OpenGL or the backplot was dreadfully slow... > >> >> Peter Wallace >> Mesa Electronics >> >> >> >> _______________________________________________ >> Emc-users mailing list >> Emc-users@lists.sourceforge.net >> https://lists.sourceforge.net/lists/listinfo/emc-users > > > Cheers, Gene Heskett > -- > "There are four boxes to be used in defense of liberty: > soap, ballot, jury, and ammo.
