2.10 or 2.9 will work but you need a recent build.
(newer than 1 month ago)


 

Ther is no 2.10, where can i find it and i download the 2.9 now, and same problem help please

You cannot use the standard release as they are only updated about once a year.
For a binary update, you need to use the image built by the LinuxCNC buildbot:

buildbot.linuxcnc.org/

(The page is a bit old as 2.10 is the current LinuxCNC master version and 2.9
is the current release version)

 The other option is to build from source:
