LinuxCNC 2.8 Downloads
- LinuxCNC 2.8.2 Debian 10 Buster PREEMPT-RT ISO
The Debian 10 Buster ISO uses a PREEMPT-RT patch which is close to mainstream Linux but does not, in some cases, give quite such good realtime performance as the previous RTAI kernel. It is very often more than good enough. It should probably be the first version tried even if using a parallel port. This is compatible with all Mesa and Pico interface boards.
- LinuxCNC 2.8.0 Debian 7 Wheezy RTAI
- LinuxCNC 2.8.2 Debian 10 Buster RTAI
The more adventurous can install the Buster ISO and then install the experimental RTAI kernel as described in 2.8 documents
- LinuxCNC 2.8.1 Raspberry Pi OS based on Debian 10 Buster
Raspberry Pi 4 Uspace compatible with Mesa Ethernet and SPI interface boards.
LinuxCNC 2.7 Downloads
The Debian 7 Wheezy ISO uses RTAI which LinuxCNC has used as the Realtime layer since the very beginning. This gives the best real-time performance and is generally a better choice for software stepping using a parallel port. However making a stable version of a 4.x Kernel for Stretch (and eventually Buster) has proven difficult, which is partly why we still distribute the EOL Wheezy. This is compatible with Mesa PCI and PCIe and Pico interface boards but is not compatible with Mesa Ethernet interface boards.
- LinuxCNC 2.7.14 Debian 7 Wheezy
The Debian 9 Stretch ISO uses a PREEMPT-RT patch which is closer to mainstream Linux but does not, in some cases, give quite such good realtime performance. It is very often more than good enough. It should probably be the first version tried even if using a parallel port. This is compatible with all Mesa and Pico interface boards.
- LinuxCNC Uspace 2.7.0 Debian 9 Stretch
The LinuxCNC Buildbot builds several different versions of OS’s and is the best way to get the 2.8 (master) version. If you have a gantry type of machine the 2.8 supports dual motor gantry homing.
More information on downloading and installing is in the LinuxCNC Documents
LinuxCNC debian packages aka .deb files can be installed on a system with dpkg from the command line or with GDebi as a graphical install method. You will need to have a Preempt RT kernel to run Uspace.
