Linuxcnc on Intel NUC unsupported kernel version? was created by 3D-Master
Hello,
i was trying to install Linuxcnc on my Intel NUC NUC7PJYH2 with Ubuntu installed, using this website (github.com/KurtJacobson/RF45-CNC/wiki/In...g-LinuxCNC-on-Ubuntu) but when i tried to install the kernel and modules (sudo apt-get install linux-image-3.4-9-rtai-686-pae rtai-modules-3.4-9-rtai-686-pae) i got:
E: amd64-microcode: unsupported kernel version!
E: intel-microcode: unsupported kernel version!
and when i tried to install the headers (sudo apt-get install linux-headers-3.4-9-rtai-686-pae) i got:
die folgenden pakete haben unerfüllte abhängigkeiten:
linux-headers-3.4-9-rtai-686-pae:i386 : hängt ab von: gcc-4.6:i386 ist aber nicht installierbar
E: probleme können nicht korrigiert werden, sie haben zurückgehaltene defekte pakete
just for info i tried installing Linuxcnc using a usb stick but it didnt show up as boot device, only ubuntu did work and i thought i could install linuxcnc on ubuntu
my ubuntu version is 18.04.1 LTS codename bionic
kernel version is 4.15.0-38-generic
can someone help me?

The link you gave mentioned using Ubuntu 18.04........which is quite a few major versions different.
Why don't you install Linuxcnc from the official image ?
To transfer the downloaded image to a USB stick on windows use Win32DiskImager, the other utilities such as Rufus, are to smart for their own good for transferring Linuxcnc iso to a USB stick.
The Linuxcnc image has to transferred to the usb disk by a "raw byte by byte" method, which Win32DiskImager does, other utilities (from what I have seen) is the mount the image and copy the files to the USB disk, this method does not work.
If you are using Linux to transfer the image use dd.
These are the 2 methods that work and you will have no trouble with.

I would try the Debian Stretch image here:
www.linuxcnc.org/testing-stretch-rtpreempt/
This has a much newer kernel (4.9) than the Wheezy image with 3.4.9 RTAI kernel
if this does not work, you may have to install a recent Ubuntu or Debian dist and build a Preempt-RT kernel ( latest Preempt-RT kernel is currently 4.18.12 )
If this is just for simulation (not running hardware) you can run LinuxCNC with the stock (non-RT) kernel

He was asking about RTAI kernel... Are you using software stepping? (parallel port)

This is for a NUC = no parallel port

Now with the stretch version i see:
UEFI : USB . SMI USB DISK 1100 : PART 0 : OS BOOTLOADER
but when i click on it i get:
GNU GRUB version 2.02~beta3-5
minimal BASH-like line editing is supported. foer the first word, TAB lists possible command completions. Anywhere else TAB lists possible device or file completions.
grub>
and when i enter Boot it says:
error: you need to load the kernel first.

i finally was able to install the stretch Linuxcnc version (linuxcnc-stretch-uspace-amd64-r12). so far i made a quick latency test and got around 40.000 and 50.000 (the smaller number is the upper and the higher number is the lower number). Is this good enough for an ethernet connection to mesa cards considering i wanna build a 5 axis machine with a spindle and tool magazine servo (all with encoders)? I have already disabled energy saving options and wifi/bluetooth. Is there anything more i can disable?
thanks
thanks
