Linux OS and CommandCNC

 Updates for CommandCNC™ and for SheetCAM POSTS

As of September 2019 we started shipping systems with an updated Linux OS we call CNC-Xf.  It is derived from Xubuntu 18.04, and it is now a 64-bit OS.  Practically this means that if your system was shipped on or after 9/18/2019 you probably need the 64-bit update below.  If you download the wrong one for your system it will not install and will show an error message saying you need the other installer.
A simple way to tell which OS you have is by the system menu in the top left corner of the screen.

CNC-Xf menu button:    download this update:
LINUX 64-bit CommandCNC Update 1.2.2

Xubuntu 14.04 menu button:    download this update:
LINUX 32-bit CommandCNC Update 1.2.2

<div id=”commandcnc”>This is an update file for systems that already have CommandCNC installed on the Linux computer that was received from CandCNC with the purchase of a Linux System or Linux upgrade.</div>

IMPORTANT! After updating, be sure to open and resave all your CommandCNC profiles in the configurator to update them and make them compatible with the new version of CommandCNC

1.2.2 has gantry homing improvements, outputs turn off in Estop, ethernet port is properly locked to CommandCNC again.
contains some bug fixes (see Updates Manual below).  The 64-bit version installs a new system kernel and changes some options to fix issues with some computers.  You must reboot the computer after installing this update if you are running the new 64-bit OS!
