Debian 13

Installing LinuxCNC 2.9 (Master)

System > Adminstration > Synaptic Package Manager Search for linux-image and install the following packages.


When booting up select Advanced options for Debian GNU/Linux and pick the rt kernel.

After booting up open a terminal (Ctrl Alt t) and make sure you have the rt kernel.

uname -a
Debian 13 Uname

Now you can remove the non-rt kernel and header by opening the Synaptic Package Manager and search for linux-image. This will make sure the PC boots up to the Preempt_RT kernel every time.

If your not using a Mesa 7i96S you can install LinuxCNC from the Debian repo. Open a terminal with (Ctrl Alt t)

sudo apt update
sudo apt dist-upgrade
sudo apt install linuxcnc-uspace
sudo apt install linuxcnc-uspace-dev

If you have a Mesa 7i96S don’t install LinuxCNC or Mesaflash from the Debian repository, they are not new enough to know about the 7i96S. If you have installed LinuxCNC from Debian remove it in the Synaptic Package Manager.

Open a terminal (Ctrl Alt t) to build and install LinuxCNC clone into the ~/emc directory. Install the depenencies then build the deb and install it.

When you get a blue screen just press Enter for the default.
