Download Information

New Installation

  1. Download the ISO (EU Mirror)
  2. Verify the MD5SUM matches 76dc2416b917679b71255e464ede84ec
  3. Burn the ISO to a CD.
  4. Boot the computer with the CD and install.
  5. Connect to the internet and get any updates If you do not install updates, you will not have the latest version of LinuxCNC.

(Do Not Update the Ubuntu LTS version!)
  6. Read the Getting Started Manual

Other Installation Options from one of the LinuxCNC Live CDs.

You can also try out LinuxCNC without installing anything to your hard disk.

The LinuxCNC Live CD are based on Ubuntu 8.04 "Hardy Heron" LTS and Ubuntu 10.04 "Lucid Lynx" LTS with additional packages maintained by the LinuxCNC development team.

Note: Do Not upgrade Ubuntu from 6.06 to 8.04 or upgrade from 8.04 to 8.10. The precompiled versions of LinuxCNC are only compatible with the Ubuntu version they were compiled with. Upgrading will remove the LinuxCNC packages and make your system unable to run LinuxCNC .

With this configuration, you continue to get all the benefits of Ubuntu, such as security updates and excellent community-based support for the base OS, plus support of the LinuxCNC components by the LinuxCNC team. (Ubuntu is the preferred way to use LinuxCNC).
